[Displaced femoral neck fractures: internal fixation or arthroplasty?].

Femoral neck fractures are a challenge for orthopedic surgeon due to the high rate of complication for such fractures. The aim of this study was to propose a treatment algorithm based on author's current concept in management of femoral neck fractures. Fractures were classified according Garden in four types but, for practical reasons, fractures were considered undisplaced (Garden I and II) and displaced (Garden III and IV). Treatment method was chosen based on next criteria: patient's age, associated pathology, patient's mental status and expectations, quality of the bone (osteoporosis), type and age of fracture, quality of reduction. Based on this criteria, the proposal algorithm may led to close reduction and internal fixation, open reduction and internal fixation or arthroplasty.
