Differentiation of Pediatric Osteochondroma From Trevor's Disease and Successful Surgical Management: A Case Report.

Osteochondroma is the most common benign bone tumor; however, its presentation in the small bones of the appendicular skeleton, particularly the talus and subtalar joint, is quite rare. Although most cases of osteochondroma are asymptomatic, symptomatic presentations can lead to joint deformity, pain, swelling, tarsal tunnel syndrome, gait alterations, and a limited range of motion. Surgical resection has proven to be an effective treatment for symptomatic osteochondromas. This case report describes the management of a rare presentation of an isolated lateral osteochondroma of the talus successfully treated with surgical excision without evidence of recurrence 1.5 years postoperatively.
