ABSTRACT
Background: The coracoacromial ligament (CAL) as an integral component of the coracoacromial arch, plays animportant role in shoulder biomechanics, joint stability, and proprioception thus maintains static restraint dueto its dynamic interactions with ligaments, muscles and bony elements around the shoulder joint. Age-dependentchanges due to chronic stress and cellular degradation cause thickening and stiffening of the CAL that maycontribute to a spectrum of shoulder pathology from capsular tightness to rotator cuff tear arthropathy andimpingement syndrome.Objectives: This study conducted to observe the different types of CAL and its relationship with coracoacromialveil.Materials and Methods: The study conducted on 50 upper limbs at Bowring & Lady Curzon medical college &research institute and Bangalore medical college & research institute. The upper limbs were dissected at theshoulder joint complex and acromion process and coracoid process were appreciated and coracoacromialligaments were appreciated for their types and morphometry.Results and Conclusion: Four types of CAL were observed in this study. These are Y shaped CAL in 12 (24%) upperlimbs, broad banded in 8 (16%), quadrangular band shaped in 25 (50%) and multiple banded in 5(10
