桡骨头切除对肘关节远期稳定性影响的临床研究

Clinical research of the impact of resection of radial head on long-term stability of elbow joint

目的:探讨桡骨头切除对肘关节远期稳定性的影响。方法:对单纯行桡骨头切除的30例桡骨头粉碎骨折患者作长期随访,分别从临床指标及放射学指标两方面进行评估。结果:术后随访2～10年(平均5.5年),桡骨头切除后会出现较多的并发症,如肘、腕关节疼痛(占66.7%及40%),前臂旋转功能障碍(占40%),桡骨干上移、侧移(占30%),肘、腕关节骨性关节炎(占76.7%及60%),下尺桡关节脱位或半脱位(占26.7%)等。结论:临床上要重视桡骨头粉碎性骨折的治疗,桡骨头切除会出现较多的并发症,应慎重选择,不可作为单纯性桡骨头骨折的首选方法。

Objective： To disscuss the impact of resection of radial head on long-term stability of elbow joint.Methods：30 patients with comminuted radial head fractures were followed-up for a long-term,and conducted an evaluation of them from clinical and radiological aspects,respectively.Results：The postoperative follow-up lasted for 2-10 years（average 5.5 years）,a lot of complications occured after resection of radial head ,such as arthralgia in elbow joint and wrist joint（66.7% and 40%）, disorders of spin function of forearm（40%）, up-shift and side-shift of radial shaft（30%）, osteoarthritis of elbow and wrist joint（76.7% and 60%）,and distal radioulnar joint dislocation and semidislocation（26.7%）and so on. Conclusions：It shoud pay more attentions to the clinical treatment of comminuted radial head fractures .The excision of the head of radius must be performed prudently because of the complications,and it cannot be considered as the first choice.
