What is a coracoid fracture?
Coracoid process fractures are an uncommon type of scapular fracture. They do not often occur in isolation and are often associated with acromial, clavicular, or other scapular fracture, as well as glenohumeral dislocation or acromioclavicular joint injury.
Can you feel coracoid process?
The coracoid process is palpable just below the lateral end of the clavicle (collar bone). It is otherwise known as the “Surgeon’s Lighthouse” because it serves as a landmark to avoid neurovascular damage.
Do humans have coracoid?
In therian mammals (including humans), a coracoid process is present as part of the scapula, but this is not homologous with the coracoid bone of most other vertebrates.
What does the coracoid do?
The coracoid process (from Greek κόραξ, raven) is a small hook-like structure on the lateral edge of the superior anterior portion of the scapula (hence: coracoid, or “like a raven’s beak”). Pointing laterally forward, it, together with the acromion, serves to stabilize the shoulder joint.
Is the coracoid process a bone?
The coracoid process is a hook-shaped bone structure projecting anterolaterally from the superior aspect of the scapular neck.
What does the coracoid bone do?
The coracoid is a stout strong bone that connects the cranial edge of the sternum to the shoulder joint complex. It opposes the powerful contraction of the major pectoral muscle during the downstroke of the wing.
What is the purpose of the coracoid?
What is the difference between coracoid and coronoid?
The key difference between coronoid and coracoid is their distribution; coronoid process is present as a pointed projection of the ulna while the coracoid process is present as a pointed projection of the scapula. Movement and structure play important roles in the skeletal-muscular system.

What is the rate of incidence for coracoid fractures?
Fractures of the coracoid process are uncommon, comprising approximately 13% of all scapular fractures and 5% of all shoulder fractures ( 19, 20 ). Coracoid fractures are usually seen with other fractures of the scapula or shoulder region; isolated coracoid fractures are rare ( 21 ).
How do you fix a coracoid bone defect?
The surgical technique involves performing an osteotomy of the coracoid to yield a bone graft that is transferred to the anterior inferior glenoid bone defect, often through a horizontal slit made in the subscapularis tendon that is subsequently closed.
What is the normal length of a coracoid?
It is determined by measuring the extension of the coracoid process laterally past a line drawn tangentially to the articular surface of the glenoid fossa. The average normal value reported in the literature is approximately 8 mm ( 7 ).
