Coracoid
Coracoid
The Coracoid (/kɔːrəkɔɪd/; from Greek korax, meaning "raven" and eidos, "shape") is a small hook-like structure on the lateral edge of the superior anterior part of the Scapula.
Etymology
The term "Coracoid" is derived from the Greek words korax, which means "raven", and eidos, which means "shape". This is due to the structure's resemblance to a raven's beak.
Anatomy
The coracoid process is a bony projection off the Scapula. It is located on the superior, lateral edge of the scapula, and it is curved anteriorly and laterally. The coracoid process serves as a point of attachment for several muscles and ligaments, including the Pectoralis minor, the Coracobrachialis, and the Short head of the Biceps brachii.
Clinical Significance
The coracoid process can be involved in several pathologies. It can be fractured, and it can also be involved in conditions such as Impingement syndrome and Frozen shoulder. In some surgical procedures, the coracoid process may be transferred for the treatment of recurrent Shoulder dislocation.
