尺骨撞击综合征的临床及影像学特点

Clinical and imageological characteristics of ulnar impingement

目的探讨尺骨撞击综合征的临床及影像学特点。方法对2008年5月-2014年12月骨科门诊明确诊断为尺骨撞击综合征的31例患者进行回顾性分析，总结尺骨撞击综合征的主要临床表现及影像学特点。结果31例均有腕关节尺侧慢性疼痛，旋转或尺偏时尤为明显，可伴有腕关节无力感；尺腕关节间隙背例及尺侧压痛阳性，腕尺侧压力试验阳性，尺骨阳性变异者约占71％；MRI检查发现月骨近端尺侧及三角骨近端桡侧部分不同程度的信号异常。结论医师应提高对尺骨撞击综合征临床表现及影像学特点的认识水平，不断提高腕关节疼痛疾病的检出率，减少尺骨撞击综合征的误诊及漏诊率。

Objective To investigate the clinical and imageological characteristics of ulnar impingement. Methods retrospective analysis was performed on 31 cases of ulnar impingement diagnosed at orthopaedic department of our hospital. The clinical and imageological characteristics were summarized. Results All the patients presented with chronic ular wrist pain with exacerbation on rotation of the joint. Possible concommitant symptoms include pailess of wrist, tender in uLnocarpal space and positive stress sign on ular wrist. 71% of the patients exhibited ulna variation, in which abnormal signal was detected by MrI on ular side of proximal lunar bone and radial side of proximal triangular bone. Conclusion Diagnosticians need detailed knowledge of ulna impingement to improve accurate diagnosis and avoid dianostic error.
