Fractures of the proximal forearm in young children may be unstable with the elbow flexed but stable with it in extension. Fifteen such fractures were managed by immobilisation in long-arm casts with the elbow extended. Only one patient had more than 15 degrees angulation at the time of bony union. All obtained normal elbow movement at two weeks and full forearm rotation at follow-up. No casts fell off. The extended elbow cast is awkward but it provides an alternative to internal fixation for some unstable fractures.
幼儿前臂近端骨折在肘关节屈曲时可能不稳定，但在伸直时稳定。15例此类骨折通过伸直位长臂石膏固定进行治疗。只有1例患者在骨愈合时出现超过15度的成角。所有患者在两周时肘关节活动均正常，随访时前臂旋转功能完全恢复。没有石膏脱落。伸直位肘关节石膏固定虽操作不便，但为一些不稳定骨折提供了内固定之外的另一种选择。
