目的：观察肱骨内上髁炎手术治疗的临床效果，并探讨手术技巧。方法自2011年1月至2013年2月，我科对24例保守治疗效果欠佳的肱骨内上髁炎患者行开放手术治疗，切除旋前屈肌群肌腱起始处的退变组织。对比患者术前、术后的肘关节患者自我报告式 HHS2评分和 Mayo 评分，进行统计学分析以评价手术效果。结果24例术后均获8～23个月随访，平均13.7个月。分别于术前、术后1、2、6个月进行肘关节患者自我报告式HHS2评分和Mayo评分，术前HHS2评分为73.2±6.4，术后1个月为93.0±4.7，2个月为92.5±5.0，6个月为94.5±5.1；术前 Mayo 评分为72.8±5.8，术后1个月为83.2±6.3，2个月为87.9±4.9，6个月为91.7±6.0。结果显示患者的主观感觉和肘关节功能较术前明显改善。24例中19例(79.2%)长期随访效果良好，2例(8.3%)残留肘内侧轻度慢性疼痛，3例(12.5%)因发生尺神经炎行二次手术治疗，术后神经症状获得缓解。结论开放手术治疗顽固性肱骨内上髁炎疗效可靠，对于合并尺神经病变的患者，建议预防性松解和前置尺神经。“,”Objective To observe the clinical outcomes of surgical treatment of medial epicondylitis and to investigate the surgical technique. Methods From January 2011 to February 2013, 24 patients with medial epicondylitis underwent open surgery, who all had a poor response to conservative treatment. The degenerated tissues at the starting points of pronator teres tendons were resected. The preoperative and postoperative Harris Hip Scores 2 ( HHS2 ) and Mayo scores were compared, which were reported by the patients themselves with pain in the elbow, and the surgical outcomes were evaluated based on the statistical analysis. Results All the 24 patients were followed up for an average period of 13.7 months ( range:8-23 months ). The HHS2 were 73.2±6.4 points, 93.0±4.7 points, 92.5±5.0 points and 94.5±5.1 points preoperatively and at the 1st, 2nd and 6th month postoperatively. The Mayo scores were 72.8±5.8 points, 83.2±6.3 points, 87.9±4.9 points and 91.7±6.0 points preoperatively and at the 1st, 2nd and 6th month postoperatively. The HSS2 and Mayo scores showed the apparent improvement of the subjective sensation and the elbow function after the surgery. Good long-term outcomes were noticed in 19 of the 24 patients ( 79.2%). Two patients ( 8.3%) had mild chronic pain on the medial side of the elbow. Three patients ( 12.5%) had secondary procedures because of ulnar neuritis, whose neurological symptoms were improved postoperatively. Conclusions The outcomes of open surgery are reliable in the treatment of refractory medial epicondylitis. Prophylactic neurolysis and anterior transposition of the ulnar nerve are recommended in the patients with combined ulnar neuritis.
