强直性脊柱炎累及髋关节的全髋人工关节置换术

目的 探讨对强直性脊柱炎累及髋关节患者实施全髋人工关节置换术的临床特点、手术技术难点及中长期疗效.方法 对1986年5月～2004年6月34例(41髋)强直性脊柱炎累及髋关节患者施行全髋人工关节置换术并进行随访,所有患者均得到完整的临床及X 线片资料,平均随访时间为7.1年(2.2～19.3 年).结果 所有患者术后的临床症状及髋关节活动度均得到明显改善, Harris评分术前平均为33.9分(13.0～59.2分),术后改善为86.2分(72～96分).髋关节术前总活动度为45°(0～150°),术后改善为130°(70°～210°).随访时3例(4髋)出现假体的松动(均为骨水泥假体),其中1例患者术后10年行股骨柄及髋臼杯假体翻修术,其余患者无假体松动和下沉.2例(2髋)术后发生髋关节脱位, 2例(3 髋)髋关节周围出现轻度异位骨化.结论 强直性脊柱炎累及髋关节患者行全髋人工关节置换术后在髋关节活动度改善方面略差.术中应注意到此类患者因骨盆旋转对安放髋臼杯假体方向所产生的影响,减少术后关节脱位等并发症的发生,中、长期疗效令人满意.

Total hip arthroplasty in ankylosing spondylitis: an analysis of 181 hips

The results of cemented total hip arthroplasty (THA) in patients with ankylosing spondylitis were studied to determine the utility of THA for these patients. A total of 103 patients with ankylosing spondylitis underwent 181 THAs; 72 patients (69.9%) had bilateral surgery. The mean follow-up was 10.3 years. The mean age of patients at surgery was 47 years. Before surgery, 42 hips (23.2%) were ankylosed. Revision surgery was carried out in 25 hips (13.8%). Heterotopic ossification was present in 21 hips (11.6%); however, no patients had functional impairment or reankylosis. At final follow-up examination, 173 hips (96%) had an excellent (low) pain score, and 53 hips had a normal or near-normal function score (29.2%). The probability of survival of the implant was 71% at 27 years. THA provides long-term improvement in hip function for patients with ankylosing spondylitis.     

Total hip arthroplasty in fused hips with spine stiffness in ankylosing spondylitis

Ankylosing spondylitis (AS) is characterized by involvement of the spine and hip joints with progressive stiffness and loss of function. Functional impairment is significant, with spine and hip involvement, and is predominantly seen in the younger age group. Total hip arthroplasty (THA) for fused hips with stiff spines in AS results in considerable improvement of mobility and function. Spine stiffness associated with AS needs evaluation before THA. Preoperative assessment with lateral spine radiographs shows loss of lumbar lordosis. Spinopelvic mobility is reduced with change in sacral slope from sitting to standing less than 10 degrees conforming to the stiff pattern. Care should be taken to reduce acetabular component anteversion at THA in these fused hips, as the posterior pelvic tilt would increase the risk of posterior impingement and anterior dislocation. Fused hips require femoral neck osteotomy, true acetabular floor identification and restoration of the hip center with horizontal and vertical offset to achieve a good functional outcome. Cementless and cemented fixation have shown comparable long-term results with the choice dependent on bone stock at THA. Risks at THA in AS include intraoperative fractures, dislocation, heterotopic ossification, among others. There is significant improvement of functional scores and quality of life following THA in these deserving young individuals with fused hips and spine stiffness.

Total hip arthroplasty in ankylosing spondylitis

Total hip arthroplasty was performed on 29 hips in 19 patients diagnosed with ankylosing spondylitis over a 13-year period. The results were analyzed retrospectively with an average follow-up period of more than four years. Complete pain relief was achieved in 97%, and significant gains were made in ambulatory capacity. The limited gains in total range of motion (average improvement 75 degrees) were felt to be primarily due to the high incidence of Brooker Class III and IV myositis ossificans (23%) and long-standing soft tissue contractures.

Total hip arthroplasty in Japanese patients with ankylosing spondylitis

The purpose of this study was to examine the postoperative results following THA for ankylosing spondylitis, which is very rare in Japanese. We performed uncemented THA in 31 hips between 1982 and 2007. Patients were followed up for a mean of 12 years. The 10-year survival rate was 100%, and the 15-year survival rate was 63.5%. Revision surgery was performed in 4 hips. Complications developed in 5 cases. Two patients sustained an intraoperative non-displaced fracture at the level of the calcar femorale. Three patients experienced postoperative dislocation. Although the study scale was small because of the very low prevalence (0.0065%) of the disease in Japan, the survival rate was similar to those reported overseas. All revision cases were due to mechanical loosening of the acetabular component of Lord THA, suggesting that the low survival rate was due to the performance of the prosthesis and not the pathology of ankylosing spondylitis.
