骨髓腔中的软骨瘤是一种良性肿瘤，由成熟的透明软骨组成。它偏爱手指的尺侧管骨，最常见于近端指骨，次常见于中间指骨和掌骨，且在远端指骨罕见。对于软骨瘤的治疗选择包括保守规律随访或手术。手术指示为有症状的软骨瘤或病变大于3至4厘米。本技术说明的目的是报告指近端骨的软骨瘤的内窥镜清除和骨移植的技术细节。这种微创方法可以保护涉及指骨的皮质完整性和骨膜。© 2023作者。

An enchondroma is a benign tumor in the medullary cavity of bone, which is composed of mature hyaline cartilage. It has a predilection for the ulnar-sided tubular bones of the hand and occurs most commonly in the proximal phalanx, and less commonly in the middle phalanx and metacarpals, and rarely in the distal phalanx. The treatment options for enchondromas include conservative regular follow-up or surgery. Operation is indicated in symptomatic enchondroma or lesions larger than 3 to 4 cm. The purpose of this Technical Note is to report the technical details of endoscopic curettage and bone grafting of enchondroma of proximal phalanx of finger. This minimally invasive approach can preserve the cortical integrity and periosteum of the involved phalanx.© 2023 The Authors.
