Abstract:
OBJECTIVE: To investigate the value of cementless total hip arthroplasty (THA) for the treatment of Crowe type Ⅲ developmental dysplasia of hip (DDH) in adults. METHODS: Between September 2013 and September 2015, 50 patients (51 hips) with Crowe type Ⅲ DDH were treated. There were 20 males (20 hips) and 30 females (31 hips), with the average age of 39 years (range, 19-55 years). The left side was involved in 34 cases, the right side in 15 cases, and both sides in 1 case. All patients had the symptoms of limp walking and hip pain. The disease duration was 10-47 months (mean, 26 months). The sign of "4" number test and Trendenleburg sign were positive; the Harris score was 38.9±7.1. The bilateral lower extremities discrepancy was 2.5-4.0 cm (mean, 3.3 cm) before operation. All the patients underwent cementless THA, and acetabulum by structural femoral head autograft was performed in 28 cases (28 hips). RESULTS: After operation, the incision healed by first intention. Only 2 patients (2 hips) had femoral nerve palsy, and 7 patients (7 hips) had leg swelling, which were cured after symptomatic treatment. All the patients were followed up 6-18 months (mean, 10 months). The sign of limp walking was improved after operation, hip pain was relieved in 46 patients (46 hips) and only 4 patients (5 hips) still had mild pain. The X-ray films showed bony healing at 3-6 months (mean, 5 months) after operation. At last follow-up, the patients had equal limb length with the discrepancy less than 1 cm (mean, 0.4 cm). At last follow-up, the Harris score was significantly increased to 91.2±2.8 (t=-79.77, P=0.00). CONCLUSIONS: The cementless THA is an effective method to treat Crowe type Ⅲ DDH in adults. 目的: 探讨生物型人工全髋关节置换术（total hip arthroplasty，THA）治疗Crowe Ⅲ型成人髋关节发育不良（developmental dysplasia of hip，DDH）的疗效。. 方法: 2013年9月-2015年9月，收治50例（51髋）Crowe Ⅲ型DDH患者。男20例（20髋），女30例（31髋）；年龄19～55岁，平均39岁。左髋34例、右髋15例，双髋1例。患者均伴明显跛行步态，患侧髋关节疼痛明显。临床症状出现至入院就诊时间为10～47个月，平均26个月。患髋“4”字征、Trendenleburg征均呈阳性，髋关节Harris评分为（38.9±7.1）分。单髋患者双下肢长度相差2.5～4.0 cm，平均3.3 cm。患者均采用生物型假体行THA，其中28例（28髋）行自体股骨头结构性植骨。. 结果: 术后患者切口均Ⅰ期愈合。2例（2髋）出现股神经牵拉麻木疼痛，7例（7髋）出现患肢肿胀，均对症处理后症状消失。50例均获随访，随访时间6～18个月，平均10个月。患者跛行步态均明显改善；4例（5髋）髋关节疼痛较术前明显缓解，46例（46髋）髋关节无疼痛。X线片复查示，髋关节外上方结构性植骨均在术后3～6个月达骨性愈合，平均5个月；随访期间假体均无松动、下沉；末次随访时单髋患者双下肢长度相差0～1 cm，平均0.4 cm，视为双下肢等长。末次随访，髋关节Harris评分为（91.2±2.8）分，与术前比较差异有统计学意义（t=-79.77，P=0.00）。. 结论: 对于Crowe Ⅲ型成人DDH患者，采用生物型THA治疗可获得较好疗效。.
