1. Synovectomy of the elbow affected by rheumatoid arthritis is a worthwhile procedure even in the presence of advanced radiological changes.

2. Relief of pain is good (93 per cent) and movement is retained (87 per cent).

3. Although the follow-up in this series was short, averaging nineteen months, the results seem to be maintained.

4. Good access to the joint may be had through medial and lateral incisions, and division of the olecranon is unnecessary. A lateral incision alone is not recommended.

5. The ulnar nerve should be preserved during dissection. Anterior transposition is needed only if there are neurological symptoms before operation.

1. Twenty-two feet injured at the tarso-metatarsal level are reviewed.

2. Experiments with eleven cadaveric feet are reported.

3. The injuries are caused by forced plantar-flexion combined with rotation in most cases. Crushing of the foot alone often does not produce dislocation.

4. A classification is suggested.

5. The results of various treatments in this small series are presented. It is concluded that anatomical reduction is important, achieved if necessary by operation and internal fixation.
