An avulsion fracture of the proximal fifth metatarsal may result in a symptomatic nonunion and hinder athletic performance. Nonoperative management is often successful in alleviating symptoms. When symptoms persist, surgery can be undertaken to repair the nonunion or excise the avulsed fragment.
The excision of the avulsed bone fragment is evaluated in the management of symptomatic nonunions.
Case series; Level of evidence, 4.
Excision of the avulsed fifth metatarsal fragment was performed in 6 male high-performance athletes with symptomatic nonunions. The remaining edge of bone was contoured and smoothed.
All 6 patients experienced an uneventful operation and recovery, returning to competitive play at a mean of 11.7 weeks. Activity-related pain and discomfort abated after the excision and rehabilitation. No surgical complications were noted.
Surgical excision of the avulsed fragment from the proximal fifth metatarsal is a safe and effective alternative intervention when nonoperative methods fail.
第五跖骨近端撕脱性骨折可能导致症状性骨不连，并影响运动表现。非手术治疗通常可成功缓解症状。当症状持续存在时，可进行手术修复骨不连或切除撕脱的骨碎片。
评估切除撕脱骨块在治疗症状性骨不连中的作用。
病例系列；证据等级，4 级。
对 6 名有症状性骨不连的高性能男性运动员进行第五跖骨近端撕脱骨块切除术。对剩余骨缘进行塑形和打磨。
6 例患者均顺利完成手术并康复，平均 11.7 周后重返竞技运动。切除和康复后，与活动相关的疼痛和不适减轻。未出现手术并发症。
对于非手术治疗失败的患者，切除第五跖骨近端撕脱骨块是一种安全有效的替代干预措施。
