[Ulnar translocation of the carpus after surgery of the rheumatic wrist. Review of 54 cases].
Fifty-four rheumatoid wrists, on which synovectomy and caput ulnar resection had been performed, were re-examined 1 to 8 years after the operation (average follow-up: 3.8 years). The clinical results were good, and the wrists pain-free in 91 per cent of cases, with a low rate of synovitis recurrence (4 per cent), and 88 per cent of the mobility in the sagittal plane was preserved. Radiological examination revealed a moderate aggravation of carpite over the years. This evolution was not linked, however, to the fact that no intracarpal synovectomy was performed in our series since a similar evolution has been reported by authors who carry out this synovectomy. Ulnar translocation of the carpus was commonly measured in relation to the ulna axis, but as the latter tends to get into a more medial position after the surgery this analysis was incorrect. Ulnar translocation should be measured in relation to the axis of the radius, which remains in the same position. Studied in this way, the average translocation in this whole series was 2 mm. A comparative study of the operated wrist and the non-operated wrist in 27 patients revealed a significant aggravation (p < 0.2) of ulnar translocation of the carpus at radiological stages 2 and 3. This translocation remained however minimal. A combined transfer of the extensor carpi radialis brevis or longus onto the extensor carpi ulnaris did not slow down ulnar translocation of the carpus, but the other hand it improved the correction of radial deviation of the carpus and ulnar deviation of the fingers.
