BACKGROUND: The long-term results of @entity1346 metacarpophalangeal arthroplasty in @entity1 with @entity309 are uncertain. The purpose of this investigation was to evaluate the subjective, objective, and radiographic outcomes at the time of long-term follow-up. METHODS: @entity1 with @entity309 who underwent simultaneous @entity1346 metacarpophalangeal joint arthroplasties of all four fingers by one surgeon were eligible for inclusion in the study. The results of a total of 208 arthroplasties in fifty-two hands of thirty-six @entity1 were evaluated at an average of fourteen years postoperatively. Active metacarpophalangeal joint motion, ulnar drift, and radiographs were assessed. The radiographs were reviewed for changes in bone length, erosions, and implant @entity174 . The Michigan Hand Outcomes Questionnaire (MHQ) was administered to the @entity1 . RESULTS: The mean arc of motion of the metacarpophalangeal joints improved from 30 degrees preoperatively to 46 degrees immediately after the surgery but decreased to 36 degrees at the time of final follow-up. The mean extension deficit of the metacarpophalangeal joints improved from 57 degrees preoperatively to 11 degrees immediately after the surgery but worsened to 23 degrees at the time of final follow-up. The mean ulnar drift improved from 26 degrees preoperatively to <5 degrees in the immediate postoperative period and then recurred to an average of 16 degrees at the time of final follow-up. Implant @entity174 were associated with increased ulnar drift (p < 0.001). Bone reaction adjacent to the implant was demonstrated by bone-shortening in most @entity1 and by erosions in 29% of the @entity1 . One hundred and thirty implants (63%) were broken and forty-five (22%) more were deformed at the time of final follow-up. The MHQ score averaged 48 of 100 points. The @entity1 expressed satisfaction with the function of only 38% of the hands, and only 27% of the hands were @entity158 -free at the time of final follow-up. A greater degree of ulnar drift was associated with decreased @entity1 satisfaction and a decreased score for the cosmetic appearance (p </= 0.01). CONCLUSIONS: The outcome after @entity1346 metacarpophalangeal joint arthroplasty in @entity1 with @entity309 worsens with long-term follow-up. Given these findings, the indications for and long-term expectations of @entity1346 metacarpophalangeal arthroplasty must be carefully examined in light of the improvements in the medical management of @entity309 .
