Involvement of toe phalanges by giant cell tumor (GCT) is extremely rare; tumors in these locations tend to be aggressive. Whereas aggressive GCTs of the distal phalanx may be managed successfully by en-bloc resection without reconstruction or amputation, management of these lesions, when they involve the proximal phalanx, can be challenging. We present a Campannaci grade III GCT of the hallucal proximal phalanx in a 14-year old girl that had breached into the dorsal soft tissues and the metatarso-phalangeal joint. Wide local resection of the proximal phalanx along with reconstruction arthrodesis with an autologous, non-vascularized fibular strut graft was performed. There was no recurrence at 3 years of follow-up. The patient had an excellent functional outcome. To the best of our knowledge, this is the first case reporting the outcomes of fibular strut arthrodesis for salvage of GCT of the hallucal proximal phalanx.
指骨巨细胞瘤（GCT）累及趾骨极为罕见；这些部位的肿瘤往往具有侵袭性。虽然通过整块切除而无需重建或截肢可成功治疗末节指骨的侵袭性 GCT，但当病变累及近节指骨时，处理这些病变可能具有挑战性。我们报告了一例 14 岁女孩的跖骨近节趾骨 Campannaci 分级 3 级 GCT，该肿瘤已侵犯背侧软组织和跖趾关节。我们采用广泛的近节趾骨局部切除术，并使用自体非血管化腓骨支柱移植进行重建融合术。3 年随访时无复发。患者的功能结局极好。据我们所知，这是首例报告腓骨支柱融合术保肢治疗跖骨近节趾骨 GCT 的病例。
