Hip dislocation following the treatment of femoral neck fracture - Case report

Abstract

Introduction: Femoral neck fractures are very rare in young patients and are frequently complicated by femoral head osteonecrosis and femoral neck nonunion. Case Outline: A 19-year-old girl with hip dislocation following the treatment of the femoral neck fracture is presented. The femoral neck fracture was initially treated by open reduction and three-screw fixation. After detecting the nonunion of femoral neck, valgus osteotomy was done. Secondary, iatrogenic, hip dislocation appeared. The patient had pains, and in clinical findings a shorter leg and limited range of motion in the hip - altogether 40 degrees. She was then successfully treated by open reduction, together with Chiari pelvic osteotomy and joint transfixation. Transfixation pin was removed three weeks following the operation. After that, the patient was put into the abduction device and physical therapy was started. The mentioned regimen lasted four months after the surgery, then the abduction device was removed and walking started. Full weight bearing was allowed eight months after surgery. Conclusion: As we have not found the literature data concerning the above mentioned problem, we solved it in the way that we usually do for the treatment of developmental dislocation of the hip in adolescence.
