Endoscopic Curettage and Bone Grafting of Enchondroma of Proximal Phalanx of Finger

Abstract

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.
