Introduction In the current system of providing medical aid to wounded servicemen, along with the conservative primary surgical treatment and minimally invasive extrafocal fixation, high-tech surgical interventions of considerable complexity with the use of additive and tissue-engineering technologies have been coming to the forefront. It is necessary to determine their place in the current algorithm of limb bone defect management, which was the substantiation of our study.

The purpose of the study was to improve the algorithm for selecting a treatment method for patients with associated gunshot defects of the forearm based on the literature and clinical observations.

Materials and Methods We analyzed scientific articles in PubMed and Scientific Electronic Library (eLIBRARY.ru) platforms, published from 2004 to 2024, on the basis of which we could refine the algorithm of treatment method selection for patients with associated gunshot defects of the forearm. The developed algorithm was used to treat 178 patients with gunshot fractures of the forearm.

Results The review of the literature established the main provisions and principles that are applied in the reconstruction of the forearm with an associated defect. When choosing the method of bone defect management, a great number of authors tend to build a “reconstructive ladder”, moving from less severe (one bone) and extended defects (small defect up to 2 cm) to more complex (both bones) and massive defect (more than 10 cm). Upon having considered the revealed regularities, we improved the algorithm of surgical treatment of the latter, which is based on two classification principles: defect extention and location. Reconstruction of the forearm as a dynamic system after diaphyseal fractures requires consider the state of the radioulnar joint. The function of the latter depends on the length ratio of the radius and ulna bones. Therefore, we substantiated small (up to 2 cm) forearm bone defects that can be managed by simple surgical methods. Another fundamental addition to the algorithm was the allocation of a patients’ group with a defect of one forearm bone and a fracture of the other bone (defect-fracture); this combination allows avoiding complex surgical methods for reconstruction and use segment shortening.

Discussion The treatment of associated forearm defects is challenging, the choice of reconstruction technique remains uncertain, and the required consensus is lacking. Several forearm reconstruction techniques are available, yet there is no reliable evidence of their effectiveness in terms of treatment time, complications, reoperations, and functional recovery.

Conclusion The algorithm proposed for the treatment of extensive gunshot-associated defects of the forearm allows us to consider the change in the anatomy, make a surgical plan based on the reconstruction vector, and select optimal surgical techniques.

Introduction Proximal carpal row resection has been used for many decades as a “salvage procedure” for progressive wrist collapse. Improving the technique of its implementation, as well as introducing various modifications of the technique into practice are an important area for achieving better results of surgical treatment.

The purpose of this work was to demonstrate aspects of the modified proximal row carpectomy (PRC) technique and the immediate results of its use.

Materials and methods Eight patients aged from 24 to 57 years (seven men and one woman) were treated with the modified PRC technique. Treatment results were assessed using an adapted QuickDASH questionnaire, a visual analogue scale (VAS), based on patient satisfaction and radiographic results.

Results The average duration of surgical intervention was (149.0 ± 35.5) minutes. In the postoperative period, six patients (75 %) underwent fixation with an Ilizarov apparatus, the rest with a plaster splint. The average range of motion of flexion and extension was (67.5 ± 18.3)°, range: 40–95°. The patients had an average of (35.6 ± 16.13)° extension, range: 10–65° and (31.87 ± 10.9)° flexion, range: 10–45°. Patients reported decreased grip strength after surgery. Pain syndrome according to VAS at rest was equal to 0–1 points and 3–4 points when the affected limb was loaded. Six patients completed the QuickDASH survey, with a mean score of (14.83 ± 4.25) points. All patients are satisfied with the result of treatment and the absence of pain at rest. Patients returned to their usual work.

Discussion Unlike the conventional dorsal approach through the III–IV tendon canals, the use of two mini-approaches provides a better cosmetic effect and makes it easier to restore the integrity of the tendon canals, which are important for the prevention of desmogenic contractures. The use of the Ilizarov apparatus has proven to be the method of choice, providing absolute stability and reduction of pain in the postoperative period. For patients under 45 years of age with increased functional demands, a balanced approach is required when choosing PRC or intercarpal arthrodesis, depending on which functional parameters are more important to the patient.

Conclusion The analysis of short-term results of using the modified PRC technique shows that it reduces the invasiveness of the operation, improves its esthetic result, provides pain relief and a satisfactory range of motion and grip strength.

Introduction Total knee arthroplasty (TKA) is the treatment of end-stage osteoarthritis in patients who failed to respond to conservative treatment in providing significant pain relief and improving joint function. The medial parapatellar approach (MPP) allows adequate patellar eversion and sufficient knee flexion to expose the knee joint, but the incision through the quadriceps tendon may impair the extensor mechanism of the knee post-operatively. The subvastus approach (SV) completely spares both the quadriceps tendon and muscle and provides adequate exposure of the knee joint for the replacement procedure, SV maintains integrity of the patellar blood supply and reduces post-operative pain resulting in shorter hospital stay.

The aim of this prospective study was to compare the results of the medial parapatellar and subvastus approaches in primary total knee arthroplasty (TKA) regarding postoperative pain, recovery of muscle strength, range of knee motion and return to regular daily activities.

Materials and Methods Sixty patients underwent TKA at El-Hadara university hospital in Alexandria. The medial parapatellar apphroach (MPP) was performed in 30 patients while the subvastus approach (SV) was used for the other 30 patients. The choice of approach was randomly assigned.

Results The statistical analysis of the results at the end of a 6-month follow-up showed that there were no significant differences between the patients in group 1 (MPP) and group 2 (SV) with respect to age, gender, comorbidity, side operated or body mass index (BMI). Regarding the functional knee scores (IKDC, WOMAC), there were no differences at 4 weeks, 3 months and 6 months postoperatively between the two groups. However, we found better outcomes in the SV group regarding the VAS score during the first five postoperative days, earlier quadriceps recovery by assessment of Straight Leg Raising test (SLR), while the operative time was longer in the SV group with less blood collected postoperatively in hemovac drain in the same group.

Discussion In our study during the operation via the MPP approach, the index suture positioned at the superomedial border of the patella and the opposite suture on the medial retinacular flap had enabled the surgeon to avoid patellar maltracking during closure of the wound. In the SV group, the L-shaped incision of the medial capsule was considered an efficient landmark for accurate soft tissue closure avoiding the patellar maltracking.

Conclusion The subvastus approach offers the advantage of keeping the integrity of quadriceps muscle and the extensor mechanism remains intact post-surgery. It causes less pain and less blood loss postoperatively than the regular parapatellar approach. The patient could recover the knee function in a shorter time with fewer complications, which is greatly in line with the concept of ERAS (Enhanced Recovery After Surgery).

Introduction Lengthening and correction of limb deformities using Ilizarov external fixation is a frequent standard operation. However, the risk of complications associated with limb lengthening, including superficial or deep infection, contractures, secondary deformity, and fractures after device removal associated with delayed bone consolidation, remains significant.

The purpose of the work was to identify the features of bone lengthening with an external fixator in combination with elastic intramedullary nails, titanium or titanium with a composite hydroxyapatite coating, in the conditions of shortening of the lower extremities of acquired etiology.

Materials and methods The study included 64 patients, of which 31 patients underwent monofocal lengthening of the femur, 33 patients underwent monofocal lengthening of the tibia.

Results The mean external fixation indices (EFIs) of the groups compared for similar lengthening types (femoral or tibial lengthening) did not differ significantly for the types of intramedullary nails implanted. In femoral lengthening, a significant effect on the EFI had the nail type and the ratio of “nail diameter / medullary canal diameter”. The dependence of EFI on the nail type in tibial lengthening was associated with the ratio “nail diameter / internal diameter at the osteotomy site” (p = 0.023). Two-way ANOVA showed that the effect of the nail type on EFI depended on the nail diameter/ internal diameter at osteotomy site ratio in the tibial lengthening group (p = 0.034).

Discussion In acquired shortening of the lower extremities, there is no difference in EFI by using titanium elastic nails or intramedullary nails coated with composite hydroxyapatite. The use of a combined technique, in any case, has advantages: it provides good and excellent results without serious complications during lengthening in patients with shortening of acquired etiology. The strong positive correlation between the bone diameter/internal cortical distance ratio at the osteotomy site, coupled with the significant influence of the nail type and nail diameter on EFI, suggests that both factors should be considered together in future studies.

Conclusion In shortening of the lower extremities of acquired etiology, the use of a combined bone lengthening technique, comprising an external fixator in combination with elastic intramedullary nailing, provides good and excellent results without serious complications.

Introduction Congenital clubfoot is a frequent malformation of the lower extremities. However, the causes of this pathology in children are still unclear. The identification of the factors associated with congenital clubfoot is a relevant problem, the solution of which will allow a prenatal prevention of clubfoot in newborns thus reducing the number of patients with this pathology.

Purpose The search for possible risk factors leading to a violation of foot development in the fetus and their significance in the occurrence of congenital clubfoot in children.

Materials and methods The study was of retrospective nature and was carried out in pairs “Mother-Newborn”. It included examination of 149 children. The first group (n = 97) was compiled by the “Mother Newborn” pairs, in which the child had a typical form of congenital clubfoot; the second group (n = 52) were pairs in which the baby was healthy. The data obtained were processed using tables 2×2 and logistics regression.

Results According to the results of the study, it was found that the greatest sensitivity and specificity of congenital clubfoot was associated with the external factor of nicotine dependence in pregnant women (SE = 0.32; SP = 0.90) and the factor of hereditarily burdened congenital foot pathology in close relatives (SE = 0.16; SP = 0.98). An acute respiratory viral infection in the anamnesis, anemia in a pregnant woman or toxicosis did not show statistically significant causal connection with the occurrence of congenital clubfoot according to the analysis using the method of logistics regression (р > 0.05) and they should not be used as prognostic ones.

Discussion The data obtained by us on the paramount significance of the two “risk” factors of the congenital clubfoot development (nicotine dependence in a pregnant woman and hereditarily burdened disorder of congenital foot pathology among close relatives) were reflected only in a few scientific sources.

Conclusion The risk factors of the greatest sensitivity, specificity and causal relationship with the congenital clubfoot development were associated with the adverse effects of the external factor of nicotine dependence during pregnancy and burdened heredity associated with congenital foot pathology in close relatives (р < 0.05).

Introduction Surgical methods for osteoporotic burst vertebral body fracture repair have their advantages and shortcomings. The use of circumferential stabilization and corrective vertebrotomies in elderly patients is highly invasive and carries great surgical risk. On the other hand, minimally invasive methods lead to recurrence of the deformity. Thus, in the treatment of patients with such pathology, it is necessary to choose a surgical method that allows achieving optimal results.

Purpose of the work was to compare the results of surgical treatment for osteoporotic burst fractures in thoracolumbar vertebral bodies using the developed method and methods of circular and hybrid stabilization based on clinical and radiological criteria.

Materials and methods The study was retrospective. Three groups of patients were formed according to the type of surgical intervention. Inclusion criteria were patients with primary osteoporosis who did not receive osteotropic therapy before surgery, with osteoporotic fractures (type OF3 and OF4) of the vertebral bodies of the thoracolumbar location (Th10–L2). The follow-up period was 12 months. The following criteria were assessed: the amount of kyphosis correction (according to the Cobb method), the amount of residual postoperative kyphotic deformity, as well as its recurrence in the long-term postoperative period; sagittal balance of the torso (Barrey index), subjective evaluation of the patient’s condition (VAS). Quality of life assessment was not performed.

Results There were no statistically significant differences in the dynamics of sagittal balance during the follow-up period between the groups (p > 0.99). There was no difference between groups in clinical outcomes (VAS) at follow-up (p > 0.05). A statistically significant difference in the magnitude of kyphotic deformity and its correction in the specified postoperative periods was revealed between the hybrid fixation groups and the corrective vertebrotomy group. No difference was found with the circular stabilization group.

Discussion Due to the high risks of poor outcomes of anterior spinal fusion, in particular, implant subsidence, to avoid anterior spinal fusion, we used a method of focal kyphosis correction and posterior spinal fusion with autologous bone. The method proposed by the authors for the correction of focal kyphotic deformity in the treatment of patients with osteoporotic burst fractures of the vertebral bodies combines satisfactory correction of focal kyphosis with minimal surgical invasiveness, which reduces the risks of complications and poor outcomes. The proposed method may also be combined with hybrid fixation.

Conclusion The developed method for focal kyphotic deformity correction in the treatment of osteoporotic burst fractures of vertebral bodies provides satisfactory correction of focal kyphosis, reduces the risks of complications and poor outcomes in comparison with circular and hybrid stabilization.

Introduction The differential diagnosis of periprosthetic joint infection (PJI) is challenging in patients with systemic diseases due to identical clinical and laboratory patterns and activity of the inflammatory process.

The objective was to evaluate the diagnostic data and results of debridement of PJI in patients with rheumatoid arthritis using a case series.

Material and methods A retrospective analysis of surgical treatment of PJI was produced in patients with rheumatoid arthritis between 2014 and 2022. PJI was verified based on ICM criteria. A poor outcome included the presence of clinical and laboratory signs of infection on admission to the second stage of treatment and recurrence after successful debridement.

Results Among the 524 cases of PJI, 35 (6.7 %) were patients with rheumatoid arthritis with 48.6 % receiving antibiotics prior to admission. Culture-negative infection was recorded in 38.4 %. PJI was not confirmed in five cases (14.3 %). High average values of inflammatory markers were registered in the blood (ESR, CRP and D-dimer) before and after debridement; decreased ESR and leukocyte count in the synovial fluid was statistically significant. Favorable outcomes were obtained in 82.9 % of cases at mid term with every fifth patient treated with a spacer or arthrodesis.

Discussion The incidence of culture-negative infection in patients with systemic diseases was reported as much as 27–37 %. A systematic review of the literature showed that the percentage of band neutrophils in synovial fluid has a sensitivity of 95.2 % and a specificity of 85.0 %, with an optimal threshold of 78 % sufficient to verify infection. The poor outcomes we identified resulted from two- or three-stage surgical treatment. Other authors reported better outcomes with two-stage debridement.

Conclusion Culture-negative infection was common in cases of PJI observed in patients with rheumatoid arthritis. Favorable outcomes were seen mostly with two-stage surgical treatment. Inflammatory markers ESR, CRP and D-dimer did not reach normal values during diagnosis and treatment of infection indicating the inapplicability of standard diagnostic criteria for PJI in patients with rheumatoid arthritis.

Introduction Premature arrest of bone growth is the most common complication of bone fractures at the growth plate level.

The purpose of the work was to evaluate the structural reorganization of metaepiphyseal cartilage following its direct injury with metal and biodegradable wires in an experiment.

Materials and methods The metaepiphyseal cartilage of the distal femur of 18 lambs of both sexes was studied. The age of the animals at the beginning of the study was (43.92 ± 0.8) days, by 60 and 120 days (102.63 ± 0.82) and (161.1 ± 0.9) days, respectively. The animals underwent transphyseal insertion of wires/ pins: series 1 — Kirschner wires, series 2 — titanium wires, series 3 — poly-L-lactic acid pins. The duration of the experiment was 60 and 120 days. Clinical and radiographic studies were carried out. Histomorphometry was performed using an AxioScope.A1 microscope and Zenblue software (CarlZeissMicroImagingGmbH, Germany).

Results Reactive changes in the growth plate at the interface with the wire were manifested by proliferation of chondrocytes in the zone of proliferating cartilage and in the reserve zone; the minimally expressed changes were noted in series 2, the most pronounced were in series 1. By the end of the experiment, at the interface with the wire in series 1, blood vessels penetrated into the metaepiphyseal cartilage; in series 3 the amount of the fibrous component was increased, which indicates further formation of “bone bridges” and “fibrous bridges,” respectively. In undamaged areas of the growth plate in all series, the zonal structure was preserved. By the end of the experiment, increased values of the thickness of the metaepiphyseal cartilage were noted (1.2 times higher than the control), differences between series were a tendency; in series 2 and 3 the ratio of metaepiphyseal cartilage zones was comparable to the control; in series 1 the proportion of the proliferating cartilage zone was increased by 4 %.

Discussion The main problem with growth plate injuries is the formation of bone tissue or fibrosis, which affects the growing process. Currently, the question of choosing a treatment tactic for growth plate injury depending on the size of the “bone bridges” is debatable. Relevant are future comparative studies of the regeneration of metaepiphyseal cartilage defects after the use of fixators made from different materials.

Conclusion Histomorphometric characteristics of the growth zone reliably showed that the insertion of wires, regardless of their material, was not accompanied by inhibition of the bone-forming function of the distal metaepiphyseal cartilage of the femur.

Introduction The Ponseti method is the first choice for congenital clubfoot with the possibilities of transverse tenotomy being underexplored in repair of the Achilles tendon in pediatric patients.

The objective was to identify specific features of the Achilles tendon repair after experimental transverse intersection and preserved peritenon, vessels and nerves of growing rabbits.

Material and methods The experimental study included 20 Chinchilla rabbits of both sexes aged 1.0–1.5 months used as a biomodel with a weight of 1476.0 ± 114.3 g. Rabbits were sacrificed in groups of five by air embolism under local anesthesia at 15, 30, 60 and 90 days of surgery.

Results The tendon defect zone was represented by small areas of dense fibrous scar tissue with some cellular fibroblasts, and tendon fibers of unremarkable architectonics arranged in a mutually parallel waves could be seen in the layers of connective tissue at 90 days. The thickness of the first-order collagen fibers increased to 8.9 ± 1.32 µm and comparison with the normal value of 9.2 ± 1.88 µm showed no statistically significant difference (p = 0.38). The thickness of the second-order collagen fibers increased to 28.1 ± 1.28 µm during the time, and comparison with the standard measurements of 28.3 ± 2.23 µm demonstrated no statistically significant difference (p = 0.64).

Discussion According to the literature, the ability of the tenoblast to synthesize structural proteins and regulatory biomolecules after injury decreases with age and leads to fibrous restoration of the tendon and formation of a permanent scar. Our study on growing rabbits showed that the organotypic structure of the experimental tendon restored at the intersection site at 60 days with the Achilles tendon defect being represented by the tendon-like tissue at 90 days.

Conclusion The Achilles tendon was shown to regenerate in optimal conditions after the dissection and preservation of the peritenon, vessels and nerves with tendon tissue being formed within a short time (3 months after the intervention) being identical to the original.

Introduction Strategical approaches to managing patients with a greater tuberosity fracture of the humerus are controversial and there are discussions about surgical treatment options. Nondisplaced fractures require no surgical management. Shoulder replacement can be indicated for the surgical treatment of proximal humeral fractures with limited function of the upper limb and difficulties in refixation of the rotator cuff tendons due to the peculiar anatomical location of the tendon fixation. Solution to this problem can improve the quality of life of patients with greater tuberosity fracture of the humerus.

The objective was to evaluate the treatment outcome of a patient with a greater tuberosity fracture of the humerus repaired with open refixation of the rotator cuff tendons and medialization of the border of the articular surface of the humerus.

Material and methods A 46-year-old patient presented with limited movements and severe pain in the left shoulder after humerus dislocation and a greater tuberosity fracture.

Results The condition was repaired with an open repair of the rotator cuff tendons and medialization of the border of the articular surface of the humerus. The patient reported neither pain nor limited movements in the left shoulder at the one-year follow-up.

Discussion Treatment options for patients with a greater tuberosity injury remains controversial. The effectiveness and results of organ-saving surgery have not been explored and require scientific evaluation using a larger cohort of patients.

Conclusion Excellent functional results were achieved in a patient with injury to the greater tuberosity using surgical refixation of the rotator cuff tendons and medialization of the cartilaginous surface.

Introduction Treatment of malunited periarticular fracture of the distal metaepiphysis of the radius in a complicated setting is challenging and involved orthopaedic care and related specialties of neurologists, neurosurgeons and rehabilitation specialists. New methods are offered for repair of the distal radius fractures but the results obtained to date cannot be considered satisfactory, since the treatment is aimed at the restoration of the anatomical relationships and the hand function.

The objective was to demonstrate the role of prehabilitation preparing patients for elective reconstructive surgery, to present a multidisciplinary approach to the treatment of malunited radius fracture complicated by posttraumatic compression ischemic multineuropathy.

Material and methods The medical history of a 56-year-old patient with distal radius malunion complicated by posttraumatic compression ischemic multineuropathy was reviewed. Outcome criteria included absence of complaints and restored function of the hand and the wrist.

Results A positive functional outcome was recorded after prehabilitation and surgery. Early postop, the DASH scored 35, palmar flexion measured 64° with dorsiflexion of 61° and dynamometry of 30 kg seen with the left involved hand. A faster recovery of the hand function occurred due to regression of neurological disorders.

Discussion Treatment of the distal radius malunion in a complicated setting suggests the involvement of related specialists including neurologists, neurosurgeons, professionals in functional and diagnostic radiology, rehabilitation specialists so that the approach must be multidisciplinary. A preoperative course of prehabilitation supervised by a neurologist and a rehabilitation specialist is essential for the patient to achieve a higher basic level of functionality. Surgical treatment must be a stage of multi-stage multidisciplinary treatment of distal radius malunion in a complicated setting.

Conclusion The clinical case showed an effective multidisciplinary approach in the treatment of distal radius malunion in a complicated setting. Preoperative preparation (prehabilitation) had a positive effect on the postoperative recovery and functional results.

Introduction Progress in shoulder surgery is associated with improved operating rooms equipment, advanced surgical products and minimally invasive techniques. There are rare injuries to nerves and vessels being intersected or pulled into the sutures. However, marginal tears, compression and nerve entrapment of trunks during access retraction, catheterization, inadequate correct of the patient on the operating table and errors in rehabilitation can be common.

The purpose was to identify factors predisposing to peripheral nerve injury to the upper limb during shoulder surgery and offer prevention options.

Material and methods Major studies in the field of shoulder anatomy and surgery published between 1984 and 2023 were reviewed to identify anatomical, biomechanical and perioperative factors leading to peripheral nerve injuries. The original literature search was conducted on key resources including GoogleScholar, PubMed, ScienceDirect, RSCI, Scopus. Four approaches were used for structuring and informative presentation of the data to include types of the peripheral nerve injury in the upper limb.

Results and discussion Factors predisposing to the peripheral nerve injury in the upper limb during shoulder surgery were identified in the review. Prevention measures include the patient positioned on the operating table with adequate fixation of the head and torso, regardless of the chosen position; traction of the involved upper limb with a load of not greater than 9 kg using a specialized clamp; preoperative marks of the surgical field and staining of bone landmarks; the arthroscopic ports 1–2 cm to be shifted more distally minimizing the fluid flow into the joint during a long operation. Postoperative consultation with rehabilitation specialists is essential to develop an early activation program and assess the risks of neurological disorders.

Conclusion The shoulder anatomy and the localization of unsafe zones of the shoulder, the risks associated with a particular manipulation were explored for effective preoperative planning and prevention of neurological complications in the treatment of surgical pathology of the shoulder joint.

Introduction Idiopathic scoliosis is characterized by a multicomponent deformity of the axial skeleton, surgical correction of which is advisable to improve the quality of life of patients. The SRS-22 questionnaire is widely used for its evaluation.

The purpose of the work was to identify and evaluate, using a systematic review method, non-surgical, socio-economic and other factors not directly related to surgical intervention that influence the results of SRS-22.

Materials and methods The search was performed on the PubMed electronic platform in accordance with the PICOS protocol. Initially, 280 articles were selected for the period of 2003-2023. The authors carried out further selection manually. The review was based on the analysis of 15 articles containing data to determine the influence of various factors on the results of the SRS-22 questionnaire.

Results It was revealed that the results of SRS-22 depend on many factors that are not directly related to either the spinal pathology itself or its surgical treatment. Contemporary studies assessing quality of life in scoliosis emphasize the influence of ethnic and socioeconomic factors on the results of the SRS-22 survey.

The results indicate differences in the assessment of the quality of life of patients with comparable pathologies depending on the geographical and social context. The role of three-way interaction between the doctor, parents and paediatric patient when assessing the results of the SRS-22 survey was considered. It was found that SRS-22 scores before and after the initial medical consultation did not have significant differences; and the assessment by parents did not differ from the assessment by the paediatric patient. A relationship was found between the use of “rigid” functional corrective braces and the results of SRS-22 — indicators of satisfaction with treatment, and, accordingly, the overall SRS-22 score in patients who received brace therapy were significantly higher. It was found that physical activity and endurance correlate with the quality of life of patients with idiopathic scoliosis.

Discussion The SRS-22 questionnaire is a key tool for assessing the quality of life of patients with scoliosis, taking into account their age and functional status. Over the years of using SRS questionnaires, various scientists have proposed several modifications to improve accuracy and ease of use, but only SRS-22 has become generally accepted. It is necessary to develop special additional algorithms that allow the results of various versions of SRS questionnaires to be interpreted into a single format for their analysis and comparison.

Conclusion The relationship and influence of the severity and structure of spinal deformity on the standard of living is an extremely heterogeneous and multicomponent issue. SRS-22 results are strongly influenced not only by medical factors, but also by age, ethnic, cultural, social and economic factors. There is a gradual change in SRS-22 scores in the postoperative period over decades since the moment of surgery. Parents are quite accurate in assessing their child's condition when using the SRS-22.
