Replacement of proximal interphalangeal joints with new ceramic arthroplasty: A prospective series of 20 proximal interphalangeal joint replacements
Bibliographic record
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 post-traumatic 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 43 degrees to 60 degrees (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.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
