目的：证实桡骨头骨折旋前复位石膏固定的可行性，为临床提供依据。方法：作者解剖观察了７例成人上肢标本，依据解剖学观察结果，用旋前复位石膏固定法治疗了３３例桡骨头骨折。结果：其中２６例患者获较为理想的复位。解剖学研究证实，前臂屈曲位旋前时桡骨外移、肱二头肌松弛，肱桡关节间隙增大，均利于复位。结论：经临床应用和解剖学研究证实，旋前复位治疗桡骨头骨折可大大提高桡骨头骨折的治愈率 Objective: To confirm the feasibility of fixing gypsum before pronation of radial head fractures and provide the basis for clinical practice. Methods: The authors examined 7 adult patients with upper extremity specimens. According to the anatomical findings, 33 cases of radial head fractures were treated with anterior displacement gypsum fixation. Results: 26 patients were more ideal reduction. Anatomical studies confirmed that the forearm flexion position when the radius of the pronation shift, biceps muscle relaxation, brachioradjabial joint space increased, are conducive to reset. Conclusion: The clinical application and anatomical study confirmed that pronation reduction for the treatment of radial head fractures can greatly improve the cure rate of radial head fractures
