Background: The triangular band known as the coracoacromial ligament connects the acromion and coracoid process,

forming an arch over the humeral head that protects it during abduction. Additionally, gleno-humeral stability depends on

It is frequently observed with anatomical variants as straight, quadrangular, or Y-shaped, and it can be observed as a

thick anterolateral bundle and a posteromedial bundle with a triangular base. In order to treat shoulder impingement

syndrome, coracoacromial ligament release is recommended during surgery.

Aim: The purpose of this study was to examine the different kinds of coracoacromial ligaments found in Indian cadavers,

as well as their function in shoulder joint biomechanics and surgical relevance.

Methods: Eighty upper limbs with undamaged shoulder joints that were obtained from Indian cadavers were evaluated

for this investigation. 10% formalin was used to embalm the corpses. After dissection, the deltoid was revealed and the

skin was mirrored. The anterior and middle deltoid muscle fibers were severed for further dissection. The coracoacromial

ligament was seen by exposing the superior surfaces of the acromian and coracoid processes
