Background and Objectives: Coraco-acromial ligament is one of the causes in the development of the subacromial impingement syndrome and its morphology shows variation. Most commonly coraco-acromial ligament has two distinct ligamentous bands. Anatomically these bands are classified as an anterolateral band and posteromedial band. Anterolateral band frequently extends anterolateraly to the acromion and it is in continuity with the fibers of the conjoint tendon of short head of biceps brachii and coracobrachialis which is known as a coraco-acromial falx. Aim of our study was to find out the incidence of coraco-acromial falx and its presence with different types of coracoacromial ligament in Indian population.
Material and Methods: We studied one hundred- (right-50; left-50) shoulders of male cadavers for the incidence of coraco-acromial falx and type coraco-acromial ligament.
Results: Our observation shows out of 100 shoulders coraco-acromial falx was present in 55. Bilaterally it was present in 33 specimens out of 55. Also, we observed incidence of coraco-acromial falx was same in all three types (quadrangular, V shaped and multiple banded) of coraco-acromial ligament.
Conclusion: The incidence of coraco-acromial falx was found more in Indian population. Orthopedic surgeon should keep this in mind while performing surgery and clinical correlation with presence of coraco-acromial falx and rotator cuff tendon tear should be observed.
