Pectoralis Major Rupture: Evaluation and Management
Bibliographic record
Abstract
Pectoralis major tendon ruptures are being reported with increasing frequency and primarily occur in young, high demand, male patients. The injury results from an eccentric contracture of the muscle most commonly while performing the bench press maneuver during weight training. In the setting of both acute and chronic injury, physical examination is critical for a timely and accurate diagnosis. During physical examination, comparison with the opposite side is imperative, and findings may include swelling, ecchymosis, loss of the anterior axillary fold, and a decreased pectoralis major index. Surgical treatment of acute ruptures is superior to nonsurgical treatment and results in improved functional outcomes and high levels of return to work and sport. Repair of chronic tears is more challenging and may require reconstruction with autograft or allograft tissue. Despite advances in surgical technique, tendon rerupture, persistent pain, and wound infection remain a concern.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
