Clinical and Radiographic Outcomes of Simple Curettage and Graft Using Allogenic Bone or Bone Substitute for Enchondroma Involving Short Tubular Bone of the Hand and Foot / 대한정형외과학회잡지

ABSTRACT

PURPOSE: We analyzed outcomes after management of enchondroma involving short tubular bones of the hand and foot by curettage and grafting using allogenic bone or bone substitutes. MATERIALS AND METHODS: Twenty-two patients (allogenic bone 15 and bone substitutes 7 patients) were recruited. Clinical results were assessed by pain, cosmetic problem, range of motion of joint and the power of grasp. Radiographic outcomes were analyzed by degree of bone defect. RESULTS: Clinically, 19 patients were classified as excellent and 3 patients as good. Three patients with K-wire fixation had pain with local irritation, which was easily controlled by removal of the K-wires. There were no complications including deep infection, delayed or nonunion, refracture. Radiographically, 20 cases were classified as group 1 (bone defect smaller than 3 mm) and the 2 remaining cases were classified as group 2 (bone defect 4-10 mm). CONCLUSION: Curettage and graft using allogenic bone or bone substitute is an effective modality of treatment for enchondroma involving short tubular bones of the hand and foot. When combined with pathologic fracture, early surgical management could shorten duration of immobilization. Surgical management might be considered for the lesion involving the foot when discovered because of high incidence of pathologic fracture.
