Treatment of patella fractures by compressive external fixation (CEF)

Abstract

Recent traditional treatment of patella fractures are related with infection and failure of fixation. The complications that we see can be treated surgically which is cost effective and limits the function of the joint. But our locally made CEF device can effectively treat patella fractures with less complications. The transverse fracture of patella with displacement were treated by compressive external fixation, based on Ilizarov tensioned wire construct. All the patients were allowed to do movements in the joints and weight bearing postoperatively. Twenty five fractures were treated with CEF. 12 patients were treated percutaneously. Sound union was achieved in all the fractures. The CEF device was removed at 6 to 8 weeks. 12 patients regained excellent motion with a mean Insall knee score of 96 points, in an average follow up of 4 years. Minor complications like wire inflammation was observed in 5 patients which was treated by local care and antibiotics. CEF technique is a safe and effective method of treatment in patella fractures with advantages over traditional methods in case with a poor soft tissue envelope. CEF allows rapid recovery and no secondary surgery is needed.
