title: The effect of the additional use of grommets in silicone implant arthroplasty of the metacarpophalangeal joints.
abstract: After silicone arthroplasty of the metacarpophalangeal (MP) joint there is increasing osteolysis, subsidence and fracture of the implants in the longer postoperative term. In 44 patients with rheumatoid arthritis (54 hands) 151 arthroplasties of the metacarpophalangeal joint were assessed at a mean of 3.9 years postoperatively. In 57 arthroplasties titanium protectors (grommets) were used. There were no significant differences in the clinical outcomes with respect to swelling, correction of ulnar deviation, range of active movement and grip strength. The additional use of grommets in MP joint arthroplasty slightly reduced reactive osteolysis, protected the spacers from breakage and slightly reduced the amount of pain with only a few additional complications in the midterm follow-up.
