【摘要】 目的:探讨肱骨大结节囊性变发生率与肩袖撕裂之间的关系。方法:回顾性总结了2006年至2008年于北京大学第三医院运动医学研究所接受肩关节镜治疗的肩袖撕裂患者74名和复发性脱位患者71名,分别为肩袖撕裂组和复发性脱位组。测量患者MRI及X线片上显示的囊性变的最大直径,并且使用X线片评估大结节及肩峰的硬化、增生情况及形态。结果:所有患者中,39.3%患者的MRI中发现有囊性变。肩袖撕裂组,60.8%患者的MRI显示有囊性变,44.6%患者的MRI及X线片同时显示有囊性变。复发性脱位组,16.9%患者的MRI显示有囊性变,8.5%患者的MRI及X线片同时可见囊性变。肩袖撕裂患者中,有囊性变的患者平均病史23个月(7天-20年),未发现囊性变的患者平均病史26.8个月(1-120个月)。X线片显示,肱骨大结节囊性变及局限性密度减低,同时伴有III型肩峰及大结节增生硬化的患者均为肩袖撕裂患者。结论:肩袖撕裂患者出现肱骨大结节囊性变的比例明显高于无肩袖损伤患者,囊性变发生率与病史无明显相关。更多还原

【Abstract】 Purpose We studied on the relationship between rotator cuff tear and cysts in the greater tuberosity of the humerus.Methods Between 2006 and 2008,145 patients received shoulder arthroscopic surgeries in our institute,of whom 74 were diagnosed as rotator cuff tear and 71 as recurrent dislocation.Patients were then divided into rotator cuff tear group and recurrent dislocation group.The maximum diameter of the cysts was measured on MRI and X-ray.Sclerosis,osteophyte and acromion shape were evaluated in X-ray.Results MRI examination found cysts in 39.9% of all patients.In rotator cuff tear group,60.8% patients were found with cysts on MRI,while 44.6% patients showed cysts on both MRI and X-ray.In recurrent dislocation group,16.9% patients were found with cysts on MRI and 8.5% patients showed cysts on both MRI and X-ray.The average duration of symptoms was 23 months(7 days-20 years) for patients with cysts,and 26.8 months(1-120 months) for the patients without cysts.In the study,patients with cysts or density decrease on the X-ray and combined with type III acromion or sclerosis were all diagnosed with rotator cuff tear.Conclusion Incidence of humeral tuberosity cysts in rotator cuff tear group was significant higher than that in recurrent dislocation group.However,there was no significant association between the incidence of cysts with the duration of shoulder pain.更多还原
