Osteochondroma of the talus: three varying cases.

Osteochondroma of the talus is a rare entity that can cause pain, swelling, restriction of movements, synovitis and tarsal tunnel syndrome (TTS). We present three such cases with varying presentation. Case 1 presented with synovitis of the ankle along with a bifocal origin of the talar osteochondroma. Case 2 presented with TTS as a result of compression of the posterior tibial nerve. Case 3 presented with deformity of the foot. In all the three cases, the mass was excised en bloc and histologically proven to be osteochondroma. In case 3, the ankle joint was reconstructed with plate, bone graft and arthrodesis of the inferior tibiofibular joint. All the three cases had good clinical outcomes.
