Shoulder: medial displacement of the biceps brachii tendon

Contributor(s): Neil Burton

Introduction

  • Uncommon - follows rupture of transverse humeral ligament.
  • Signs: lameness gradual in onset - worsens with exercise.
  • Pain/crepitation on shoulder manipulation, tendon may be felt to 'pop' out of intertubercular groove.
  • Treatment: relocation and retention in intertubercular groove.
  • Prognosis: guarded for return to full work.

Pathogenesis

Pathophysiology

  • Displacement of biceps tendon follows rupture of transverse humeral ligament.
  • Lameness is gradual in onset and worsens with exercise.
  • Tendon may be felt to 'pop' out of intertubercular groove medially on joint flexion, and return to groove on extension.
  • There may be an associated luxation of shoulder joint due to loss of cranial support.
