1. The results of synovectomy of the knee in eighty-five patients with rheumatoid arthritis are presented.

2. When reviewed between five and nine years after operation 55 per cent of 122 knees still had improvement in pain.

3. Only 31 per cent of knees lost movement.

4. Recurrence of symptoms in nearly all cases was related to the recurrence of active rheumatoid synovitis.

5. Recurrence of symptoms was a little less likely when the generalised disease improved, when the Rose-Waaler test was negative, when only one knee was involved and when the operation had been carried out within three years of the onset of disease in that knee.

1. The early signs of Paget's disease of the acetabulum and femur are described.

2. The pattern of arthritis is presented in 199 hips in which Paget's disease of bone occurred in either the femur, the acetabulum or both bones. Distinct patterns of disease occur with different bone involvement.

3. Selective narrowing of the medial segment of the joint is common and is particularly associated with pelvic disease. Why the narrowing occurs here preferentially is unexplained.

4. Protrusio acetabuli occurred in only 25 per cent of hips and usually when both the femur and the acetabulum were involved. This may be due to the presence simultaneously of weakened bone and coxa vara, the latter leading to an alteration in the direction of the resultant force across the hip joint.

5. Degenerative arthritis was present with Paget's disease in 14 per cent of hips but it may be a chance relationship in half of these hips.

1. A report is presented of the results of a trial to compare the effects of early and late weight-bearing in patients with a transcervical fracture of the femur treated by reduction of the fracture and internal fixation with a sliding nail-plate.

2. One hundred and twelve patients have been assessed clinically and radiologically three years after operation.

3. Retrospective analysis of factors that affect the outcome of treatment suggests that the two groups were fairly evenly balanced.

4. The results show that full weight-bearing two weeks after operation did not increase the incidence of failure of fixation or of non-union.

5. The higher incidence of superior segmental collapse in patients in whom weight-bearing was deferred for twelve weeks can be explained by the greater number of high fractures in this group and the greater number with a poor reduction.
