Twenty-three rheumatoid arthritis patients were assessed at an average of 59 months after operation, which exceeds the resorption time of P(L\/D)LA 96\/4 according to animal experiments. Palmar subluxation exceeded half of the bone thickness in 39 joints before operation and in nine at the last follow-up. Ulnar deviation decreased from 25\u00b0 to 5\u00b0, extension deficit from 32\u00b0 to 15\u00b0 and active flexion from 76\u00b0 to 63\u00b0. The results are comparable with published data on silicone implant arthroplasties. Implant resorption did not induce any significant osteolysis in the medium term and the restoration of the structure and function of the hand was maintained after implant resorption, probably as the guided fibrous tissues had replaced the dissolved implant.<\/jats:p>","DOI":"10.1177\/1753193408099833","type":"journal-article","created":{"date-parts":[[2009,3,12]],"date-time":"2009-03-12T21:09:28Z","timestamp":1236892168000},"page":"179-185","source":"Crossref","is-referenced-by-count":24,"title":["A Midterm Follow-Up Study of Bioreconstructive Polylactide Scaffold Implants in Metacarpophalangeal Joint Arthroplasty in Rheumatoid Arthritis Patients"],"prefix":"10.1177","volume":"34","author":[{"given":"P.
