1. A further report is made upon the problem of rigid valgus foot due to talocalcaneal bridge, supplementing the original report in 19483.
2. A group of cases has been identified in which the bone anomaly is incomplete and does not reveal itself directly by x-ray. In many cases characteristic secondary roentgenographic changes in the talonavicular joint are present and the heel is fixed in valgus.
3. So far, all such cases explored by operation have revealed themselves to be due to the existence either of the calcaneal or of the talar element of a talocalcaneal bridge. In either case the bone mass limits movement by acting as a bone block.
4. Operative treatment of rigid valgus foot should be limited to the relief of disabling pain and the correction of severe deformity. It should consist in subtalar fusion through a medial approach, supplemented by talonavicular fusion when necessary.
