The value of scapho-trapezio-trapezoid arthrodesis combined with "de la Caffinière" arthroplasty for the treatment of pan-trapezial osteoarthritis.
13 patients, 12 female and one male (mean age 63) with pan-trapezial osteoarthritis were treated by a "de la Caffinière" arthroplasty of the first carpometacarpal joint, combined with a scapho-trapezio-trapezoid (STT) arthrodesis. 11 could be reviewed at least 3 years after surgery (average 3 years and 8 months). Non-union of the arthrodesis occurred twice, once when no internal stabilization was used, once with the use of the staplizer. No impingement syndrome was recorded, and there was no correlation between the angular position of the scaphoid and mobility of the wrist. Two out of 11 "de la Caffinière" implants had to be removed. Loosening of the stem is unusual, but the cup remained only perfectly in place in two cases. There was no correlation between radiological and clinical findings and the overall result was good or excellent in 8 out of 13 (62%) of the cases. The grip and pinch strength were comparable to the results of the literature. This method cannot be further recommended because of the high rate of re-operation and the risk to the trapezium which has to be further evaluated.
