Tumors affecting tarsal bones are a rare occurrence, accounting for approximately 1% of primary tumors of the skeleton, with the calcaneus being the most frequent site. Osteoblastoma occurrence in the bones of the foot is not infrequent, ranging from 3.4 to 11.1% of the cases in different series, with the talus most common followed by the calcaneus. Total excision of the calcaneus can be the treatment of choice in aggressive benign tumors and in selected cases of malignant tumors. Reconstruction of the heel after total calcanectomy is a challenging procedure and different techniques have been proposed. Due to the rarity of this condition, most of the reports in the literature involved a single case with no series reported. We describe two cases of aggressive osteoblastomas extensively affecting the calcaneus requiring total calcanectomy. In order to restore a functional weightbearing hindfoot after calcaneus excision, in both cases we performed a heel reconstruction by vascularized iliac crest graft fixed to the talus and the cuboid. Oncological, radiographic and functional results of these procedures at an average followup of 7 (range, 6.6 to 7.7) years are reported.

Abstract

Tumors affecting tarsal bones are a rare occurrence, accounting for approximately 1% of primary tumors of the skeleton, with the calcaneus being the most frequent site. Osteoblastoma occurrence in the bones of the foot is not infrequent, ranging from 3.4 to 11.1% of the cases in different series, with the talus most common followed by the calcaneus. Total excision of the calcaneus can be the treatment of choice in aggressive benign tumors and in selected cases of malignant tumors. Reconstruction of the heel after total calcanectomy is a challenging procedure and different techniques have been proposed. Due to the rarity of this condition, most of the reports in the literature involved a single case with no series reported. We describe two cases of aggressive osteoblastomas extensively affecting the calcaneus requiring total calcanectomy. In order to restore a functional weightbearing hindfoot after calcaneus excision, in both cases we performed a heel reconstruction by vascularized iliac crest graft fixed to the talus and the cuboid. Oncological, radiographic and functional results of these procedures at an average followup of 7 (range, 6.6 to 7.7) years are reported.
