Одним из условий воздействия на остеорепарацию при блокируемом интрамедуллярном остеосинтезе (БИОС) является динамизация штифта.

Проведено лечение пациента 66 лет с несросшимся межвертельным переломом правой бедренной кости, осложненным поломкой интрамедуллярного штифта.

Через два месяца после проведенного вмешательства достигнуто рентгенологическое сращение перелома и функциональное восстановление пациента. Причиной отсутствия межотломковой компрессии при БИОС может являться блокировка скользящего винта латеральным кортикальным слоем периферического отломка бедренной кости. Данную проблему возможно предупредить выполнением латеральной кортикотомии при первичном остеосинтезе вышеуказанных переломов.</p></sec><sec><title>Обсуждение</title><p>Обсуждение. На основании научных публикаций и собственной клинической практики мы предположили, что показанием для выполнения LCN является нарушение консолидации при межвертельных переломах 31А3.1–3 по классификации AO/OTA, при 3 типе переломов вертельной области по классификации Boyd и Griffin, а также при всех типах подвертельных переломов по классификации Seinsheimer, когда при выполнении цефаломедуллярного остеосинтеза возникает необходимость в создании вектора межотломковой компрессии по оси бедренной кости. В приведенном клиническом случае отражен механизм нарушения консолидации при ряде переломов межвертельной и подвертельной области бедренной кости.</p></sec><sec><title>Заключение</title><p>Заключение.

The procedure can be difficult to perform in some sub- and intertrochanteric femoral fractures due to anatomical and functional features.</p><p>The objective was to demonstrate a case of successful use of an original version of the lateral cortical notching (LCN) technique for dynamization of an intramedullary proximal nail in a patient with a nonunited subtrochanteric fracture.</p><p>Material and methods The treatment was performed for a 66-year-old patient with a non-united intertrochanteric fracture of the right femur complicated by the breakage of an intramedullary nail. The LCN technique was successfully used to dynamize the IM nail.</p><p>Results Radiological healing of the fracture and functional recovery of the patient were observed at a two-month follow-up. The absence of interfragmental compression in IIN could be caused by blocking of the sliding screw by the lateral cortical bone of the peripheral femur fragment. The complication could be prevented with LCN during primary osteosynthesis of the above fractures.</p><p>Discussion Based on scientific publications and our clinical experience, we assumed that LCN can be indicated for  failed healing of intertrochanteric AO/OTA 31A3.1–3 fractures, type 3 Boyd and Griffin trochanteric fractures and all types of subtrochanteric fractures as graded by Seinsheimer with a vector of interfragmental compression to be created along the femur axis during cephalomedullary osteosynthesis. The case report showed the mechanism of impaired consolidation in some intertrochanteric and subtrochanteric fractures of the femur.</p><p>Conclusion The case report demonstrateed the successful use of the original version of the lateral cortical notching (LCN) technique for dynamization of an intramedullary proximal nail.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>подвертельный перелом</kwd><kwd>интрамедуллярный остеосинтез</kwd><kwd>латеральная кортикотомия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>subtrochanteric fracture</kwd><kwd>intramedullary nailing</kwd><kwd>lateral cortical notching</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Barbosa de Toledo Lourenço PR, Pires RE.
