We analysed the results of arthroscopic synovectomy of the wrist in 18 patients (19 wrists) with rheumatoid arthritis who had not responded to conservative treatment. The patients’ symptoms were assessed using visual analogue scales for pain and satisfaction. Standard posteroanterior radiographs which were taken pre-operatively and at final follow-up were analysed using a modified Larsen scoring system (normal, 0; total destruction, 40). The mean follow-up period was 29.2 months (24 to 45). The mean pre-operative pain score was 8.58 which decreased to 3.58 one year after surgery and increased again to 4.42 at final follow-up. This suggested a gradual increase in pain with time. The mean satisfaction score was 6.26. The mean modified Larsen’s score was 9.8 pre-operatively and 13.9 at final follow-up, which demonstrated the slow progression of degenerative changes.

Arthroscopic synovectomy for rheumatoid arthritis of the wrist allows effective pain relief and high patient satisfaction, although any prolonged benefits will require long-term follow-up.

The extent of necrosis is the main determining factor in the outcome of osteonecrosis of the femoral head and is best measured by MRI.

Using statistical analyses, we have evaluated the accuracy and repeatability of seven different methods of measuring the extent of necrosis, of which three demonstrate good or acceptable accuracy. For the general observer their repeatability is poor; only for experienced observers were they reasonable. We conclude that within an institution or for personal use, the accuracy of some methods is acceptable, and repeatability reasonable. None is appropriate for international use.
