What does the conoid ligament do?
The conoid ligament limits anterior movement of the scapula with respect to the clavicle. The trapezoid limits posterior movement between these two bones. Both ligaments prevent the clavicle from overriding the lateral end of the clavicle.
Where is conoid ligament located?
The conoid ligament attaches to the clavicle at the conoid tubercle, which is posterior medial to the trapezoid tubercle. From superior to inferior, the conoid ligament appears as an inferior pointing cone.
What is the trapezoid line?
From the conoid tubercle an oblique ridge, the trapezoid line (or trapezoid ridge, or oblique), runs forward and lateralward, and affords attachment to the trapezoid ligament on inferior surface of clavicle. Trapezoid line. Left clavicle.
What is costoclavicular ligament?
The costoclavicular ligament binds the inferior medial clavicle (via the rhomboid fossa) to the first costal cartilage and the adjacent end of the first rib. It is composed of an anterior lamina and posterior lamina which are usually separated by a bursa.
What ligament connects scapula to clavicle?
Coraco-clavicular Ligaments
Coraco-clavicular Ligaments (CCL): These two ligaments (trapezoid and conoid ligaments) attach the clavicle coracoid process of the scapula. These tiny ligaments (with the acomioclavicular joint) play an important role in keeping the scapula attached to the clavicle and thus keeping your shoulder ‘square’.
What is Interclavicular ligament?
The interclavicular ligament is a flattened band, which varies considerably in form and size in different individuals, it passes in a curved direction from the upper part of the sternal end of one clavicle to that of the other, and is also attached to the upper margin of the sternum.
Where is the Infraglenoid tubercle?
the scapula
The infraglenoid tubercle is the part of the scapula from which the long head of the triceps brachii muscle originates. The infraglenoid tubercle is a tubercle located on the lateral part of the scapula, inferior to (below) the glenoid cavity.
Where does costoclavicular ligament attach?
What causes costoclavicular syndrome?
A scissoring action of the clavicle against the first rib narrows the costoclavicular passage and shears the neurovascular bundle. The first rib elevates toward/against the clavicle. This often occurs in clients who have laboured breathing. Tight anterior and middle scalenes and subclavius can also cause this to occur.
What are the 4 ligaments of the shoulder?
