肩关节动态造影下液压扩张手法松解治疗冻结肩

Treatment of frozen shoulder by hydraulic distension and manipulation under dynamic arthrography of shoul-der joint

目的探讨动态造影下液压扩张手法松解(hydraulicdistensionandmanipulationunderdy-namicarthrography,HDMDA)治疗冻结肩的疗效及其影响因素。方法2000年3月～2001年3月间按制定的病例选择标准选择100例冻结肩患者随机分为两组,分别采用HDMDA和药物治疗进行对照研究,并观察HDMDA术中注入液量、粘连松解程度、肱二头肌长头腱滑囊显影情况与HDMDA疗效的关系。结果100例患者均获随访,随访时间1021个月。近期疗效(5个月)和远期疗效(10～21个月)HDMDA治疗组优良率分别为86%、90%,药物组优良率分别为48%、34%,两组疗效比较差异有显著性(u近=2.322,u远=3.556,P<0.05);同时发现HDMDA治疗后盂肱关节在每一方向的活动度均优于药物组(校正χ2检验,P<0.05)。HDMDA术中注入液量≤15ml者,远期随访优良率仅为25%;肱二头肌长头腱滑囊未显影的9例患者远期随访良2例、差7例。结论HDMDA是诊断和治疗冻结肩的有效方法,该法创伤小、简单易行、并发症少且疗效可靠、持久;HDMDA术中注入的液量、关节粘连松解程度尤其是松解后肱二头肌长头腱滑囊的显影情况均影响其疗效。

Objective The investigation was to evaluate the efficiency of the frozen shoulder treated by hydraulic distention and manipulation under dynamic arthrography of shoulder joint ,and analyze the in-fluencing factors on the outcome.Methods One hundred patients with frozen shoulders were enrolled the prospective and controlled study,who were divided into two groups randomly.Fifty patients were treated by the hydraulic distention and manipulation under dynamic arthrography of shoulder joint (GroupⅠ),and fifty patients were treated by NSAIDs administration(GroupⅡ).The relationship of clinical results with the amounts of injected fluid during hydraulic distention and manipulation,the range of motion,the visualized rate of the vagina synovialis of long head of biceps brachii tendon and subacromial bursa,and releasing de-gree of joint adherence were observed.The patients consisting of forty-two males and58females aging from42to74years were assessed at two time-intervals.The short term follow-up period ranged from3to6months,and final follow-up from10to21months.Results The clinical results was significantly difference between GroupⅠand GroupⅡdepending on daily activity and range of motion(P<0.05).The percentage of excellent and good results in hydraulic distention and manipulation under dynamic arthrography group were86%and90%respectively;while that of medication group were48%and34%respectively.The range of motion in GroupⅠshowed significant advantages compared to GroupⅡ(compensatedχ 2 test,P<0.05).If the injected amount was less than15ml in hydraulic distention and manipulation under dynamic arthrog-raphy group,the excellent and good rate was only25%.Furthermore,there were9cases of non-visualized vagina synovialis of long head of biceps brachii tendon in the arthrography,a good result was in2cases,poor result in7cases.Conclusion The hydraulic distension and manipulation under dynamic arthrography of shoulder joint is less traumatic,easy to perform and really an effective procedure to diagnose and treat the frozen shoulder.The amount of fluid and the degree of the shoulder adhesion are essential factors to out-come.
