目的评估关节镜下清除钙化性肌腱炎肩袖钙化病灶的治疗效果,探讨急性期组与慢性期组手术治疗后的疗效差别。方法收集北京大学人民医院创伤骨科2009年9月至2014年6月收治的钙化性肌腱炎病例,符合标准者28例。按照发病至手术时间的不同分为急性期组和慢性期组,比较两组术后Constant评分提升幅度,SST问卷增长个数,前屈、外旋角度改善及VAS评分下降的情况。结果急性期组在术后Constant评分(t=3.242,P=0.003)、SST问卷完成个数(t=2.080,P=0.048)、前屈角度(t=2.08,P=0.048)及VAS评分(t=2.394,P=0.024)四方面改善程度优于慢性期组,而两组在外旋角度改善方面差异无统计学意义(t=0.764,P=0.452)。结论关节镜下钙化灶清除可以显著改善患者肩关节功能、缓解疼痛。急性期患者与慢性期患者临床疗效相当。

英文摘要：

Background Calcifying tendonitis of rotator cuff is a common disease that causes pain .It frequently occurs in people at 30‐50s ,especially in women .The acute calcifying tendonitis is characterized by persistent severe pain of shoulder joint of unknow n reason .In case of severe symptoms ,emergency treatment is needed .Most patients with acute phase diseases have good efficacy for conservative treatment .However ,patients who do not respond to conservative treatment or with symptoms unrelieved that severely influence work and life ,surgery that removes the calcifying lesion under the arthroscopy is recognized as the effective treatment .Recently ,with the development of arthroscopy ,removal of calcium compounds under the arthroscopy has become a common surgery and leads to good efficacy .This study was performed to assess the efficacy of removal of calcified lesion under arthroscopy for calcifying tendonitis of rotator cuff in patients with acute and chronic phases of diseases ,and to determine the difference in shoulder joint function between acute and chronic phases after surgery .Methods General data:Cases with calcifying tendonitis who received treatment from September 2009 to June 2014 were included in this study .The inclusion criteria included :(1) who had history of severe shoulder joint pain;(2) who did not respond to conservative therapy ;(3) who received arthroscopy .The exclusion criteria included :(1) who had complicated injury of rotator cuff ;(2) who received open surgery .28 cases who met inclusion criteria were enrolled .The patients were assigned to the acute group and the chronic group by the time from the acute onset to removal of calcified lesion under arthroscopy .The acute group received removal of calcified lesion within 3 months after the onset of shoulder pain .The chronic group received removal of calcified lesion 3 months after the onset of shoulder pain that limited range of motion .28 cases had different degrees of pain and limited range of motion in the affected shoulder joi
