目的 评估带血管蒂豌豆骨移位治疗月骨缺血性坏死的中长期疗效.方法 1993年7月至2005年6月,采用月骨切除带血管蒂豌豆骨移位治疗月骨缺血性坏死患者11例,男6例,女5例;年龄20～67岁,平均（41.0±14.3）岁.Lichtman月骨缺血性坏死分期：Ⅲa期4例,Ⅲb期5例,Ⅳ期2例.末次随访时评估腕痛主观感受、视觉模拟评分（visual analogue scale,VAS）、患侧腕关节活动度（range of motion,ROM）、握力、Cooney腕关节功能评分及影像学变化.结果 患者随访61～202个月,平均（104.1±48.4）个月.10例患者腕痛缓解,7例达到基本无痛.疼痛VAS评分（2.2±1.9）分.患侧腕ROM为健侧的65.3%,握力为健侧的84.3%.Cooney腕关节功能评分优1例、良7例、可2例、差1例,优良率72.7%.X线片显示8例豌豆骨植入位置正常,2例向掌侧移位,1例向尺侧移位,舟豌豆间隙增宽;6例豌豆骨有正常骨小梁结构,3例萎缩变扁,2例有硬化改变;3例有骨关节炎改变.腕高比值、Nattrass指数较术前明显降低,桡舟角较术前增大,差异有统计学意义.结论 采用月骨切除带血管蒂豌豆骨移位是治疗Ⅲ～Ⅳ期月骨缺血性坏死的一种有效方法.术后虽可出现腕骨塌陷,但患者主观满意度高,握力好.
Objective To evaluate the long-term efficacy of vascularized pisiform transfer for patients with Kienb（o）ck＇s disease in Lichtman stages Ⅲ-Ⅳ. Methods Eleven patients were reviewed to analyze results after lunate resection and vascularized pisiform transfer for Lichtman stages Ⅲ and Ⅳ. There were six men and five women. Age ranged from 20 to 67 years with a average of 41.0±14.3 years. According to Lichtman stage. There were 4 cases in stage Ⅲa, 5 cases in stage Ⅲb, and 2 cases in stage Ⅳ. Assessment criteria included subjective assessment of pain, visual analogue scale （VAS）, range of motion （ROM）, grip power,Cooney wrist score and radiographic changes on each follow-up visit. The radiographic changes including pis iform bone location, shape, sclerosis change, osteoarthritis, carpal height ratio, Nattrass index, Radioscaphoid angle and ulnar variance were recorded. Results The follow-up periods of all of cases were 61-202 months,with an average of 104.1 months. Pain had improved in 10 patients and disappeared in 7 cases. The VAS score was 2.2±1.9 at follow-up visit. Range of motion of injured wristw as only 65.3% of opposite side. Grip power was 84.3% of the contralateral hand. According to Cooney score, the results were excellent in 1 case, good in 7cases, fair in 2 cases and poor in 1 case, with the excellent and good rate of 72.7%. Radiologically, 8 cases had normal position of the pisiform bone, 2 had volar displacement and 1 had ulnar displacement which leaded to widen scaphopisiform space. Six pisiform bones had normal trabecular structure, three had degenerative changes. Bone sclerosis was seen in 2 cases and osteoarthritis was found in 3 patients. Compared with radiographic parameter before surgery, carpal height ratio and Nattrass index significantly lowered and radioscaphoid angle significantly increased. Conclusion Lunate resection and vascularized pisiform transfer is an effective method for Kienb（o）k′s disease in stages Ⅲ-Ⅳ. Although carpal collapse appeared postoperatively,the results show high patient satisfaction and good function after vascularized bone transplantation.
