To describe pertinent anatomic findings during repair of chronic, partial distal biceps tendon tears and to compare the complications of surgery with a similar cohort of acute, complete tears.
Partial distal biceps tendon ruptures showed a consistent pattern of pathology involving disruption of the lateral side of the tendon insertion involving the small head of the biceps. Degenerative intratendinous ganglion formation was present in one third of cases. Repair of chronic, partial distal biceps tendon injuries may have a higher incidence of posterior interosseous and lateral antebrachial cutaneous nerve palsies.
Level of evidence: Therapeutic III. Copyright remains with the authors and publisher.
