The third-generation percutaneous chevron and Akin osteotomy (PECA) technique for surgical management of hallux valgus has shown improvement in clinical and radiographic outcomes. During this procedure, lateral translation and fixation of the first metatarsal head results in the formation of a bony prominence on the medial side of the distal aspect of the first metatarsal which can cause pain and discomfort to the patient. We describe two techniques to address this bony prominence; either i) excision osteotomy and removal of the fragment or ii) a dorsal closing wedge osteotomy retaining the bony fragment. LEVEL OF EVIDENCE: Level V, expert opinion.
第三代经皮 Chevron 和 Akin 截骨术（PECA）技术用于治疗拇外翻的手术治疗，在临床和影像学结果方面均有改善。在该手术中，第一跖骨头的外侧移位和固定导致第一跖骨远侧端内侧形成骨性隆起，可引起患者疼痛和不适。我们描述了两种解决该骨性隆起的技术；（i）切除截骨术并切除骨块，或（ii）保留骨块的背侧闭合楔形截骨术。证据等级：V 级，专家意见。
