Displaced fractures of the lateral humeral condyle have been successfully treated with closed or open reduction and pinning. However, there is no consensus as to when the implants should be removed, with the recommended time ranging from 3 to 8 weeks. The purpose of this study was to assess the results after treatment of displaced lateral condyle fractures of the humerus in children and formulate guidelines for removing the implants. Fifty-five patients with displaced fractures were included in this study. A modified Hardacre functional rating system was used to grade the final clinical result. In 50 patients the fracture was clinically and radiographically healed at 6 weeks, in 4 patients at 5 weeks, and in only 1 patient at 4 weeks. The implants should not be removed until healing can be demonstrated radiographically. This time averaged 6 or more weeks in most of the patients in this study.
肱骨外侧髁移位骨折已通过闭合或切开复位及穿针固定得到成功治疗。然而，对于何时取出内固定物尚无共识，推荐时间从3周到8周不等。本研究的目的是评估儿童肱骨外侧髁移位骨折治疗后的结果，并制定取出内固定物的指导原则。本研究纳入了55例移位骨折患者。采用改良的Hardacre功能评分系统对最终临床结果进行分级。50例患者骨折在6周时临床及影像学愈合，4例在5周时愈合，仅1例在4周时愈合。在影像学证实骨折愈合之前不应取出内固定物。本研究中大多数患者的这一时间平均为6周或更长时间。
