Intraosseous Ganglion Cyst of the Scaphoid Treated by Curettage and Zaidemberg’s Vascularized Radial Bone Graft

Abstract

An intraosseous ganglion cyst is an uncommon pathologic condition with histological similarities to the soft tissue ganglion cyst. Carpal bones especially the scaphoid is a rare location of an intraosseous ganglion cyst. We report the case of a 42-year-old right-handed man who presented with a painful left wrist evolving for nine months. The pain was localized at the anatomical snuff-box. It was increased with activity and slightly relieved with analgesic medication. Plain radiographs of the left wrist revealed a radiolucent cystic lesion of the scaphoid without any fracture, loss of joint space or degenerative changes. CT-scan confirmed the lucent area with a sclerotic margin within the scaphoid, communicating with the joint space. Through a volar approach, curettage and a Zaidemberg’s vascularized radial bone grafting was performed.
