Abstract
The Moje Acamo carpometacarpal (CMC) implant is an uncemented large ball-and-socket joint made of a ceramic material coated with a bioactive substance (Bioverit) for osseous fixation. Nine Moje Acamo CMC prostheses were implanted into nine patients with primary osteoarthritis of the thumb CMC joint. At 12 months, three implants had been revised because of progressing pain and osteolysis. In the remaining six patients, radiographs have shown progressive osteolysis around both implants in five patients. These poor results mean that we no longer perform this operation and we recommend close follow-up of all cases that have been performed.
