BackgroundOnly 3 % of osseous tumors occur in the foot. The metatarsals are the –most common site whereas the calcaneus and talus are less common sites. Because these tumors are rare, the aim of our study is to assess the functional and the oncological outcome of patients with benign hindfoot tumors managed by curettage. MethodsThe clinical and radiological data of 41 patients diagnosed with benign hindfoot tumors were retrospectively reviewed. The study included 31 males and 10 females. The average age was 23.68 (range, 5–49) years. The average follow-up period was 92.7 (range, 12–244) months. ResultsAt the last follow-up visit, the average Musculoskeletal Tumor Society scoring system (MSTS) score was 28.12 (range, 21–30). MSTS scores were higher in patients with latent tumors (P = .028) and patients managed by simple curettage (P = .018). The recurrence rate in calcaneal tumors was higher than those in the talus. The overall complication rate was 12.2 % (5 of 41 patients). Infection and subtalar arthritis were the most common complications. ConclusionCurettage of benign bone tumors of talus or calcaneus proved to be an effective method in the management of these patients. Their functional outcome is also excellent. All the complications are manageable without long term morbidity. Level of evidenceLevel IV Therapeutic study.
