- Forty patients (156 metacarpophalangeal joints) with mutilating rheumatoid arthritis were randomly allocated in a blinded manner to have either NeuFlex or Sutter implants. Indications for operation were pain and severe deformity. Thirty-nine patients were followed up postoperatively for one year. An independent physiotherapist and occupational therapist examined each one. Grip strength, range of motion, and pain during activity and at rest were measured. The Canadian Occupational Performance Measure (COPM) assessed the patients' evaluation of their occupational performance. Both groups had overall good results, but it seems that though patients' mobility and grip strength improve considerably, pain seems to do so only relatively. Most patients seem to be satisfied with the operation and their functional gain. Five out of 78 Sutter and two out of 78 NeuFlex implants broke. We found no major differences between the two designs, but the patients in the NeuFlex group seemed to be more satisfied with their occupational performance (COPM performance) ( p = 0.05).

Tidskriftsartikel (refereegranskat)abstract
- A prospective consecutive series of 20 proximal interphalangeal ( PIP) joints replaced with a new ceramic unconstrained prosthesis (MOJE) included 13 patients with osteoarthrosis, five with rheumatoid arthritis, and one each with posttraumatic infection and traumatic arthrosis. All patients were assessed preoperatively and postoperatively at one year by an independent physiotherapist and an occupational therapist who evaluated grip strength, range of motion, activities of daily living (ADL) and occupational scores (COPM Canadian Occupational Performance Measure). The mean range of motion of the PIP joint improved from 438 to 608 ( p = 0.001), and the mean grip strength from 169 - 199 N ( p = 0.002). The patients' self-perception of occupational performance, assessed by the COPM, improved significantly from 3.6 - 6.6 (p< 0.001) for satisfaction, and 3.8 - 6.3 (p< 0.001) for performance. The MOJE PIP joint replacement provides significant pain relief, improved strength and range of motion, and short-term satisfaction. Further long-term studies are therefore advocated.
