摘要

BACKGROUND:The mechanism responsible and the best form of treatment for fractures of osteochondromas remain unclear.
PURPOSE:We studied the incidence, cause, treatment, and outcome of fractures of osteochondroma over a 17-year period.
STUDY DESIGN:Retrospective cohort study.
METHODS:We retrospectively reviewed all cases of osteochondroma at one institution over 17 years (1985 to 2002) to identify cases of fractures. These patients were then contacted for follow-up.
RESULTS:Seven cases of fracture through the stalk of a pedunculated osteochondroma were identified. All fractures were sustained during physical exercise. One fracture was due to a direct blow, and the others to indirect muscle or tendon injury. Five patients were treated surgically with excision of the osteochondroma, and the other two received nonoperative treatment consisting of restriction of physical activity and observation. In all cases, patients were able to resume sporting activity within 4 to 8 weeks. The recovery period was shorter for patients who received surgical treatment.
CONCLUSIONS:Surgical excision of the fractured osteochondroma may be preferable for patients engaging in sport.

背景: 负责的机制和骨软骨瘤骨折的最佳治疗形式仍不清楚。
目的: 我们研究了 17 年来骨软骨瘤骨折的发生率、原因、治疗和结果。
研究设计: 回顾性队列研究。
方法: 我们回顾性分析了一家机构 17 年 (1985 至 2002年) 的所有骨软骨瘤病例，以确定骨折病例。然后联系这些患者进行随访。
结果: 确定了 7 例通过带蒂骨软骨瘤柄的骨折。所有骨折都是在体育锻炼期间维持的。一种骨折是由于直接的打击，另一种是由于间接的肌肉或肌腱损伤。五名患者接受了手术切除骨软骨瘤，另外两名接受了非手术治疗，包括限制体力活动和观察。在所有情况下，患者都能在 4 到 8 周内恢复运动活动。接受手术治疗的患者的恢复期更短。
结论: 骨折骨软骨瘤的手术切除可能是从事运动的患者的首选。
