Case Discussion

Talar Coalition.

This is a rare condition. Many times may remain undiagnosed until it becomes symptomatic.

Tarsal Coalition is a fibrous, fibro-cartilaginous or ossified abnormal union of two bones, resulting from non-segmentation of primitive mesenchyme cells. The reported incidence is 1to 5.6% of general population. CN – Calcaneo-Navicular (44%) and TC  - Talo-Calcaneal (48%) are the most common. With Talo-Navicular and Calcaneo-Cuboid also being seen less commonly. Bilaterallty is seen in upto 50 – 60% of the occurences.
