To analyze the pathogenesis feature and treatment of talar osteochondroma.
From 2000 to 2016, 14 patients with talar osteochondroma surgically
treated in our institution were retrospectively analyzed. Of them, 10
males and 4 females were confirmed the definitive diagnosis by
combination of clinical, imaging and pathological aspects. Moreover, a
review of the published studies of talar osteochondroma was conducted to
analyze the clinical and imaging features.
The 14 patients aged from 6 to 47 years with a mean age of 20.86 years
at onset of the disease. Solitary osteochondroma occurred in 11 patents,
while multiple osteochondroma in 3 patients, associated with the
recurrent lesion in 3 cases of them. However, no malignant
transformation happened in any of them. In term of lesion location, 9
patients were involved in the left and 6 in the right foot, including
the medial talus affected in 9 patients, the lateral talus in 2, the
front talus in 3, and the rear talus in 6 patients, associated with
ankle loose body in 2 patients. The main clinical symptoms included
pain, local swelling, motion limitation and walking difficulty.
The incidence of osteochondroma of the talus is rather lower, and most of the lesions are benign ones with a male predominance. The lesions more commonly involve in the medial side than the lateral side and the rear than the front of the talus. Clinical presentation is related to the location of tumor. Conservative treatment is proper for asymptomatic patients, while surgical resection is an effective treatment for symptomatic patients.
