Kết quả thành công phụ thuộc vào một kế hoạch cẩn thận trước phẫu thuật, và một thành phần quan trọng của Kế hoạch đó là Phương pháp phẫu thuật. Việc lựa chọn phương pháp tiếp cận dựa trên nên bị chỉ định sửa đổi, | Surgical Approaches in Revision Hip Replacement Eric L. Masterson BSc MCh FRCS Bassam A. Masri MD FRCSC and Clive P Duncan MB MSc FRCSC Abstract Revision hip arthroplasty will be performed with frequency in the future. A successful outcome depends on careful preoperative planning and a key component of that plan is the surgical approach. The choice of the approach should be based on the indication for revision the particular implant to be removed the presence of acetabular or femoral bone loss previous surgical approaches used and the preferences and training of the surgeon. For simple revision procedures one of the standard approaches used in primary hip arthroplasty may be adequate. More complex cases may necessitate an extended exposure or one of the techniques developed specifically for revision arthroplasty. No single approach is suitable for all revision procedures and the surgeon must be familiar with a range of exposures if the clinical result is to be optimized. J Am Acad Orthop Surg 1998 6 84-92 Approximately 200 000 primary total hip replacements are currently being performed annually in the United States. Given a greater willingness to offer the procedure to younger patients a population that is living longer and the fact that implants have only a finite useful life span there is little doubt that the number of patients coming to revision surgery will continue to increase. Revision hip arthroplasty requires careful preoperative planning and the choice of surgical approach is one of the most important components of this plan. An ideal approach should achieve a number of key objectives. First it should provide satisfactory exposure of both the components to be removed as well as any bone defects that may be present and any neurovascular structures that need to be identified and protected. Second it should not result in uncontrolled bone or soft-tissue damage during removal of the implant. It is always preferable to perform planned adequate incisions or .
