Enchondromas are benign bone tumours originating from cartilages. It is mainly discovered incidentally in radiographs or due to symptoms like pathological fracture or pain. Conservative treatment through regular check-up and surgical excision using curettage are the two major treatment methods for enchondromas. This review concludes that small localized asymptomatic lesions can be treated conservatively while most expanding or symptomatic lesions should be treated with simple curettage. Adjuvant treatments like high-speed burring or alcohol instillation are not recommended.

Ten consecutive patients with digital enchondroma were treated by curettage and calcium phosphate bone cement (CPC) injection under digital nerve block. Mean patient age at surgery was 39 years old (range, 26-54), and the mean follow-up period was 19 months (range, 12-31). Two patients had a pathologic fracture at the first visit. Active finger motion was allowed at three days postoperatively and all patients returned to work within four weeks of surgery. The surgical procedures were uneventful in all patients, and no complications were encountered during follow-up. The mean total arc of motion of the PIP joints and MP joints of the affected fingers was 93% of and 99%, respectively, of the arcs of the corresponding joints of the contralateral unaffected fingers at final follow-up. CPC injection is a good option for the treatment of enchondroma of the finger.
