1. Eleven cases of congenital flat foot were studied, five of which are illustrated.

2. Ten of these cases were treated in infancy and followed for at least three years. In two cases the follow-up period was ten years and fifteen years.

3. An essential component of the deformity is equinus of the calcaneus, and treatment consisted of correction of the forefoot deformity by repeated manipulation, followed later by elongation of the calcaneal tendon and capsulotomy of the ankle.

4. The importance of recognising the deformity and beginning treatment in infancy is stressed.

1. Rupture of the brachial artery or of one of its divisions in association with elbow injuries is probably more common than a survey of the literature would imply. Three cases of rupture of the brachial artery complicating compound dislocation of the elbow are reported.

2. These cases appear to have a consistent pattern of soft-tissue damage, with avulsion of the common flexor origin, and a varying degree of damage to the biceps and brachialis. The median nerve escaped injury.

3. The method of dealing with the divided vessels does not appear to be of importance in determining the outcome, simple ligation being as satisfactory as attempts at grafting or suture.

4. In no case was there any evidence of Volkmann's contracture. Provided rapid reduction of the dislocation is effected, together with ligation of the vessels, a satisfactory return of the circulation may be expected.
