1. Attention is drawn to a type of foot in which painful plantar callosities form under one or more metatarsal heads. The affected metatarsal heads are shown to be depressed, or dropped, and this dropping is not caused by toe deformities.

2. An operation is described which elevates a dropped metatarsal head by a wedge osteotomy through the base of the metatarsal.

3. The various deformities of the tread are described, and the possible causes of this condition are discussed.

4. It is stressed that corrective metatarsal osteotomy is not appropriate for patients with deformities of their toes, who require correction of the toe deformity.

1. A method of arthrodesis of the ankle is described which combines the compression principle of Charnley with the medial approach to the joint described by Pridie.

2. Fusion occurred promptly in seventeen out of nineteen cases. In one case fusion was delayed, and in one case there was failure of fusion.

1. A modification of the Grice extra-articular subtalar arthrodesis is described.

2. The results of this operation are presented.

1. A modification of the Keller's arthroplasty is described, in which one of two types of distractor–intramedullary wire and external staple–is used to maintain normal length of the great toe for three weeks after operation.

2. The results of the modified operation are analysed. They appear to show that the use of a distractor can be expected to produce an improved end result and to aid post-operative wound healing.

3. The possible reasons for the improvement in results are discussed.

4. The intramedullary wire and the external staple are compared with respect to ease of introduction, effectiveness in maintaining distraction and end results.

A classification of Smith's fractures into three types is proposed. It is suggested that the majority of these fractures are caused by a pronation injury. The reduction of Smith's fractures by supination is described and the importance of the supinated position during splintage is stressed.
