Pectoralis major tendon repair outcomes: comparison of transosseous tunnel and cortical button fixation techniques.
Article in JSES reviews, reports, and techniques, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: The traditional gold standard for repairing pectoralis major tendon ruptures involves the utilization of a cortical trough and transosseous bone tunnels. However, it has been shown to create stress risers that could increase the risk of developing humeral fractures. Modern repair techniques have evolved using either anchors or cortical button fixation. There is currently no clinical outcome data comparing the outcomes between the 2 repair methods. This retrospective cohort study aims to compare the clinical and patient-reported outcomes between the cortical button and transosseous tunnel repair techniques in pectoralis major tendon ruptures. Methods: A retrospective chart review for pectoralis major tendon repairs was conducted, identifying 10 patients who underwent cortical-button fixation and 9 patients who underwent transosseous tunnel fixation between January 2011 and December 2021. Patient demographics and case characteristics were collected for comparison in addition to follow-up data on post-operative patient-reported outcomes, strength, range of motion, and complications. Results: At a median follow-up of 48 months (quartiles: 41, 50), we found that transosseous tunnel repair patients reported significantly worse scores compared to cortical button repair patients on both the Disabilities of the Arm, Shoulder and Hand surveys (5.0 [quartiles: 3.3, 8.3] vs. 1.3 [quartiles: 0.0, 2.3], Conclusion: The cortical button repair method for pectoralis major tendon ruptures may be associated with better long-term pain and functional outcomes as reported on the American Shoulder and Elbow Surgeons and Disabilities of the Arm, Shoulder and Hand surveys compared to the transosseous tunnel repair method, but further investigation is needed.
