Abstract

fetched live from OpenAlex

BACKGROUND: Minimally invasive pain relief treatments targeting articular nerves have emerged as treatment options for chronic joint pain, bridging the gap between conservative management and surgical intervention. These procedures have not been developed for the elbow joint due to insufficient anatomical knowledge of the articular branches innervating the elbow joint. OBJECTIVE: To determine origin, course, frequency, landmarks, and capsular distribution of the articular branches supplying the anterior elbow joint. DESIGN: Anatomical dissection study. METHODS: Six upper extremity specimens were meticulously dissected. Articular branches were traced from their origin on the brachial plexus to their termination. Origin, course, termination, and landmarks of each branch were documented and photographed in high resolution. A frequency map was generated to visualize the capsular areas supplied by each articular branch. RESULTS: The musculocutaneous and/or median nerve gave rise to an extramuscular branch supplying the capsule deep to brachialis (83%). The median nerve supplied the medial capsule via a direct articular branch (17%), branches to flexor digitorum superficialis (100%), and a branch to pronator teres (67%). The anterior interosseus nerve supplied the capsule over the proximal radioulnar joint (67%). The radial nerve provided articular innervation to the lateral capsule via a radial branch to brachialis (83%), branches to extensor carpi radialis longus (100%), and branches to supinator (100%). CONCLUSIONS: Detailed anatomical knowledge of the articular branches supplying the anterior elbow joint is essential for identifying potential targets for therapeutic intervention and exploring selective blockade of articular nerves to alleviate pain originating from specific capsular areas.

Not 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.
