Extra-articular Malunions of the Scapula: A Comparison of Functional Outcome Before and After Reconstruction
Bibliographic record
Abstract
OBJECTIVE: To assess surgical and functional results after corrective reconstruction of malunited, scapula neck or body fractures in patients who presented with chronic pain, limited range of motion, weakness, and gross deformity of the shoulder. DESIGN: Case series. SETTING: Level I teaching trauma center. PATIENTS: Between 2000 and 2008, five patients (mean age, 44 years) underwent operative reconstruction of a malunited, scapula neck and/or body fracture. Mean time from injury to surgery was 15 months (range, 8-41 months). All patients presented with debilitating pain and weakness and were unable to return to work. When measured on three-dimensional computed tomographic scan, mean preoperative fracture deformity included 3.0 cm (range, 1.7-4.2 cm) of medial/lateral displacement, 25° (range, 10°-40°) of angular deformity, and a 25° (range, 19°-29°) glenopolar angle. INTERVENTION: Surgical osteotomy and reorientation of scapula neck and/or body, with fixation using 2.7- or 3.5-mm implants and autogenous graft, through a posterior Judet approach. MAIN OUTCOMES MEASURES: Pre- and postoperative functional measures of range of motion and strength testing and patient-based outcome scores (Disabilities of the Arm, Shoulder and Hand and Short Form-36). RESULTS: Mean follow-up was 39 months (range, 18-101 months). All patients united radiographically, were pain-free with regard to the shoulder, and expressed satisfaction with their result. Four of five patients returned to their original occupation and activities. Mean Disabilities of the Arm, Shoulder and Hand score improved from 39 (range, 27-58) preoperatively to 10 (range, 0-35) postoperatively. There were no complications. CONCLUSIONS: Malunion after nonoperative treatment of a displaced scapula fracture may be associated with poor functional and cosmetic outcomes. Operative reconstruction can yield good surgical and functional results.

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.
