Introduction: Isolated enchondromas are the most common tumors of the hand. Approximately 40% affect this upper extremity, with preference for cubital rays and proximal phalanges. Risk of malignant transformation to chondrosarcoma is 1% and the risk of recurrence ranges from 2 to 15%. Our experience and results with a large number of patients with a long-term follow-up are described. Methods: Descriptive, retrospective, case series study. Patients with diagnosis of isolated enchondroma of the hand that were treated with tumor resection, curettage and iliac crest or radius autograft placement were included. After surgical treatment, hand function was assessed using the Takigawa classification, radiological results and frequency of complications or recurrence were evaluated. Results: Nineteen patients with a mean follow-up of 11 years were included. According to the Takigawa classification, function was excellent in 16 patients (84.2%) and good in 3 (15.7%). One patient had an incisional superficial surgical site infection that resolved completely. No cases of recurrence were identified. Conclusions: Good functional and radiological results were obtained after surgical treatment. Enchondromas can pose the risk of pathological fractures, recurrence and, in a lesser degree, malignant transformation; however, none of these complications were identified. The results of a simple surgical treatment option with good and excellent long-term results are described.
