Warner & McMahon (1995) studied 7 patients with isolated loss of the long head of biceps proximal attachment to quantify whether — and by how much — the biceps tendon contributes to superior glenohumeral stability during scapular-plane abduction, using blinded bilateral radiographic measurement.
When a patient presents with isolated long head of biceps rupture or tendinitis, recognize that loss of this tendon produces measurable superior humeral head migration during abduction — particularly relevant in patients with type-II or III acromial morphology, where concomitant acromioplasty at the time of tenodesis may reduce impingement risk.
