MRI观察青少年专业跳水运动员腕关节损伤类型

MRI observation on the types of wrist joint injuries in adolescent professional divers

目的采用MRI观察青少年专业跳水运动员腕关节运动相关损伤类型。方法以42例腕关节疼痛运动员患者共84个腕关节作为运动组,与15名年龄相匹配志愿者(对照组)相对比,观察其MRI表现,判断腕关节损伤类型。结果运动组84个腕关节中,19.05%(16/84)尺骨远端骺板损伤,42.86%(36/84)桡骨远端骺板损伤;40.48%(34/84)手舟骨软骨下骨质硬化,64.29%(54/84)月骨软骨下骨质硬化,61.90%(52/84)桡骨远端软骨下骨质硬化;14.29%(12/84)出现骨髓水肿;25.00%(21/84)出现腱鞘或滑膜囊肿;11.90%(10/84)三角纤维软骨复合体损伤;4.76%(4/84)出现尺骨阳性变异。对照组腕关节未见明显异常改变。结论青少年专业跳水运动员腕关节损伤主要表现为骺板损伤、软骨下骨质硬化及骨髓水肿。

Objective To observe the types of wrist joint sports-related injuries in adolescent professional divers with MRI.Methods A total of 42 professional divers(84 wrist joints)with wrist pain were included into sport group,and compared with 15 age-matched volunteers(control group).MRI features of wrist joints in sport group were observed to classify the types of injuries.Results In sport group,injuries of distal ulna epiphyseal plates and distal radial epiphyseal plates occurred in 19.05%(16/84)and 42.86%(36/84)wrists,respectively,while bone sclerosis was observed in 40.48%(34/84)subchondral osteosclerosis under scaphoid bone,64.29%(54/84)subchondral osteosclerosis under lunar bone and 61.90%(52/84)subchondral osteosclerosis under distal radius.Bone marrow edema was detected in 14.29%(12/84)wrists,and tendon sheaths or synovialis cysts were found in 25.00%(21/84)wrists.Injured triangular fibrocartilage complex was noticed in 11.90%(10/84)wrists,while 4.76%(4/84)wrists had positive ulnar variation.There was no obvious abnormal change of wrist joints in control group.Conclusion Wrist joint injuries of young professional divers mainly present as epiphyseal plate injury,subchondral osteosclerosis and bone marrow edema.
