Analysis of bony bridge over bicipital groove

Introduction Bicipital groove or intertubercular sulcus is bounded by lesser tubercle medially and greater tubercle laterally. The contents of this groove are long head of biceps brachii, synovial sheath and ascending branch of anterior circumflex humeral artery. The groove is bridged by transverse humeral ligament. This ligament has been found to be ossified. This osseous tissue may damage the contents of bicipital groove during biomechanical movements of the arm. The ossification of this ligament is a new discovery known to the author and bears clinical implications. Hence the study has been carried out. Case report During examination of bones in the osteology lab in the Department of Anatomy, we came across a rightsided humerus showing complete ossification of the transverse humeral ligament. The incidence is 1%. This osseous bridge extended from the lateral margin of the lesser tubercle to the medial margin of the greater tubercle. The horizontal, vertical lengths and thickness of the ossified ligament were 7, 5 and 2 mm, respectively. Discussion The ossified ligament may cause tendinitis of the long head of biceps brachii leading to anterior shoulder pain. It may also cause tenosynovities. Conclusion Knowledge of the ossified transverse humeral ligament may be of immense Analysis of bony bridge over bicipital groove
