1. One hundred and twenty-three patients with rheumatoid arthritis who had synovectomy and excision of the head of the radius performed on 154 elbows have been reviewed one to six years after operation.

2. The severity of the disease process at the time of operation was graded radiologically and an attempt made to relate this to the results.

3. Overall, the clinical results were most satisfactory; more than 70 per cent of the patients were pleased with the outcome. When radiographic deterioration of the joint was taken into account, however, only 54 per cent achieved a "satisfactory" result.

4. Clearance of the synovium through combined medial and lateral incisions gave better results than a lateral approach alone.

5. When the disease was far advanced by the time of operation any good results were likely to be short-lived.

6. The indications for synovectomy of the rheumatoid elbow are discussed in the light of these findings.

1. Sixty-eight crush fractures of the articular surface of the lateral tibial condyle have been analysed.

2. Follow-up examination at a minimum of three years after injury was carried out in all cases.

3. The only factors which appeared to influence the results were the extent of the original depression, and if this was severe, the degree of restoration obtained by the treatment. Prolonged plaster fixation was avoided.

4. At review, no patient complained of symptoms which were attributable to damage to ligaments or menisci and no patient had symptoms of late onset.

5. The results suggest that there is nothing to be gained by open reduction if the lateral condyle is depressed by less than 10 millimetres, as conservative treatment gives good results. If the depression is more severe, however, a good result can only be assured if the articular surface is successfully reconstituted, but this is sometimes difficult to achieve. It is not possible to reconstitute the surface by non-operative means.
