The Clinical Study Of Total Hip Arthroplasty For The Developmental Dysplasia Of Hip

Objective: Developmental hip dysplasia is a line of hip replacement surgery hip replacement surgery one of the most difficult. This paper discusses the treatment of total hip arthroplasty for developmental hip dysplasia clinical efficacy and hip replacement surgery experience and skills, to further guide clinical work.Methods: Hospital from August 2008 to January 2011 the same surgeon with total hip arthroplasty in 13 patients (18 hips) with developmental hip dysplasia in patients with recent mid-term follow-up. 1 case of a hip, male, female 12 cases 17 hips, the average age of 48 years (23 to 62 years). 5 patients underwent bilateral total hip replacement surgery, 8 patients underwent unilateral total hip arthroplasty. By Crowe type, 5 hips of typeâ… ,â…¡type 3 hips,â…¢type 3 hips,â…¢in 7 hips.Results: Operative time was 80 to 180 minutes, with an average 126 minutes,â… ,â…¡-type operation is relatively easy, using a relatively short time,â…¢,â…¢type of surgery relatively long time. Blood loss was 200 ~ 800ml, an average of 400ml, 400 ~ 800ml of blood transfusion ranging. Incision healed. 2 cases of hip dislocation (after 14 days, respectively, occurred in 40 days, give the closed reduction, closed reduction difficult given the other cases open reduction, postoperative recovery was good, up to now no further dislocation.) 3 to 28 months follow-up, Harris score of patients, the average Harris score improved from 49.53 pm to return to after 84.17 minutes. All patients without nerve injury, no infection, deep vein thrombosis. Suffering from hip pain disappeared completely satisfactory joint function.Conclusions: Total hip replacement is the treatment of developmental dysplasia of the hip and effective method. (1) Surgical preoperative preparation is to determine the success or failure of one of the important factors, good preoperative preparation can greatly reduce the intraoperative difficulties and postoperative complications incidence. (2) the release soft tissue around the hip joint is a complex issue. Direct impact on the extent and effect release of intraoperative and postoperative recovery of operating results. (3) the true position of the acetabular prosthesis, if necessary, reconstruction of the acetabulum using a special method, commonly used method for the bone graft surgery and acetabular cover manufacturing technology centers (the so-called center of the acetabulum is deepened acetabular dysplasia, To internalize and down the center of rotation to restore acetabular hip center center) (4) developmental dysplasia of the hip in patients with proximal femur variation exists, use the special prosthesis DDH (link prosthesis, the prosthesis small And no curved metaphyseal curvature) can also be used with Johnson & Johnson group of biological fixation of femoral prosthesis type correction. (5) Treatment of femoral osteotomy, shortening osteotomy of the removal of appropriate length to 1-3cm, 0.5cm to the satisfaction of each proposed extension of lower extremity surgery in less than 3cm to protect the soft tissue to protect the sciatic nerve, sciatic nerve intraoperative detection of a conditional recommendation. In short, total hip arthroplasty for developmental hip dysplasia is a very difficult and complex surgery, preoperative imaging improve, surgery soft tissue release in full, the original anatomical reconstruction of the acetabulum, the appropriate plant Bone and choose a suitable prosthesis, is key to successful operation.
