Exostosis of the Foot: Clinical Features and Outcome After Surgery: 腳的外生骨瘤—— 臨床特點和手術後的結果

Background/PurposeThere are two common diagnoses for exostosis occurring in the foot—osteochondromas and subungal exostoses.MethodsA retrospective study of patients with a diagnosis of exostosis receiving surgery from 2000 to 2011 was conducted. Sixty-five patients were reviewed. Fourteen cases of exostosis on the foot were identified.ResultsOut of fourteen cases of exostosis on the foot, nine had a subungal location and five were located on the foot. Four out of five cases on the foot showed histology of hyaline cartilage cap while fibrocartilage was shown in seven out of nine cases with lesions on the toes. In cases of subungal exostosis, excision was done via a transungal approach or wedge excision. Surgical outcome was satisfactory in terms of improvement in pain, cosmetic concern, and functional disturbance.ConclusionOsteochondroma and subungal exostosis are not uncommonly encountered diagnoses for bony outgrowths occurring over the foot region. Surgical outcome was satisfactory.

中文摘要背景腳上的外生骨瘤在組織學上有兩個診斷－骨軟骨瘤和外生性甲下骨瘤。方法從2000年到2011年，共有六十五個病人接受進行對骨瘤的手術。當中有十四個病例是腳上的外生骨瘤。結果十四個腳上的外生骨瘤中，九個是甲下的外生性骨瘤。在五個腳上而非腳指上的外生骨瘤中，四個骨瘤的組織是透明軟骨。在九個外生性甲下骨瘤的病例中，七個骨瘤的組織是纖維軟骨。而切除外生性甲下骨瘤的方法是經過甲下切除或楔形切除。結論骨軟骨瘤和外生性甲下骨瘤是頗常見的於腳部外生骨瘤的診斷。手術結果在改善疼痛、 外觀和功能障礙上令人滿意。
