Arthroscopic Debridement of the Elbow for Arthrofibrosis Resulting From Nondisplaced Fracture of the Radial Head
Bibliographic record
Abstract
PURPOSE: Mason type I fractures of the radial head consist of fractures that occur without displacement. Arthrofibrosis is a rarely reported complication of Mason I radial head fractures. Symptoms include pain, stiffness, and crepitus. We assessed the efficacy of an arthroscopic procedure including debridement and capsular release for patients with persistent symptoms and failure of nonoperative therapy. TYPE OF STUDY: Therapeutic study, case series. METHODS: Retrospective analysis of functional outcome data was carried out for all eligible cases treated at our institution between 1995 and 2003. Twenty procedures were performed, with 8 patients lost to follow-up. The outcome data consisted of range of motion measurements and functional indices derived from the Mayo Performance Index (MPI). Mean follow-up duration was 54 months. RESULTS: Surgical findings included extensive scarring in the radiocapitellar joint, cartilage loss in the radial head and capitellum, scarring and synovitis in the ulnohumeral joint, and scarring with adhesions in the posterior compartment and posterolateral gutter. The mean MPI score preoperatively was 64.1 and the mean postoperative score was 89.5. Total range of motion arc rose from 108 degrees preoperatively to 126 degrees postoperatively. CONCLUSIONS: The outcome data suggest that arthroscopic debridement and capsular release is an effective method of treating arthrofibrosis resulting from Mason I radial head fractures. LEVEL OF EVIDENCE: Level IV.

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.
