What is Corocoid process?
The coracoid process is an osseous structure that arises from the superior border of the head of the scapula, projecting forward and curving laterally. The coracoid process is located directly below the lateral fourth of the clavicle and connected to its undersurface by the coracoclavicular ligament.
Which two muscles have their origin on the coracoid process?
The conjoined tendon originates from the coracoid process. It is composed of the short head of the biceps and the coracobrachialis (both supplied by the musculocutaneous nerve).
What muscles attach to acromion process?
Two major muscles, the deltoid and trapezius, attach to the acromion. The deltoid, which abducts the arm at the shoulder, forms its origin along the acromion, the spine of the scapula, and the clavicle. From these origins, it crosses the shoulder joint and inserts on the deltoid tuberosity of the humerus.
Can you damage the coracoid process?
Coracoid process fracture is an uncommon injury, occurring in about 2-5% of all scapular fractures. It is often associated with other shoulder suspensory complex injuries such as acromioclavicular injuries, clavicular fractures, shoulder dislocations, etc.
What muscles are attached to the coracoid?
The coracoid serves as an important anchor for several tendinous and ligamentous structures, including, medially to laterally, the tendons of the pectoralis minor, coracobrachialis, and short head of the biceps brachii muscles, and, laterally to medially, the coracohumeral, coracoacromial, coracoclavicular, and …
How do you fix coracoid impingement?
The first line of treatment for coracoid impingement should be a program of activity modification, with avoidance of the provocative positions of forward flexion and medial rotation, and physical therapy to strengthen rotator cuff muscles and scapular stabilizer musculature [8, 10].
What kind of injuries are associated with coracoid fractures?
Injuries associated with coracoid fractures include acromioclavicular joint separation , glenohumeral joint injury , tear(s) of the ligaments and tendons inserting into the coracoid, rotator cuff tears, and fractures of adjacent bones such as the acromion, scapular spine, and lateral end of the clavicle.
What kind of pain is caused by coracoid impingement?
Some ligaments stretch between the coracoid process and the acromion. Pinching of the soft tissue structures by the coracoid process is referred to as coracoid impingement. The patient’s first inkling that something is wrong is a dull, aching pain along the front of the shoulder.
How does the coracoid process affect your movement?
Any change in the anatomy, shape of the bones, or position of these structures can alter movement. One problem involving the coracoid process is the focus of this article. The coracoid process is a small hook-like structure at the top front part of the scapula (shoulder blade).
Where is the coracoid process in the scapula?
The coracoid process is a small hook-like structure at the top front part of the scapula (shoulder blade). The coracoid process works together with the acromion to stabilize the shoulder joint
