Describe the structures that contribute to stability, and types of injuries likely to impact each joint.

Step 1
Step 1: Shoulder (glenohumeral joint) - Structures contributing to stability: - Static: glenoid labrum deepens socket, joint capsule and variations of capsular ligaments (glenohumeral ligaments), coracohumeral and coracoacromial arches, negative intra-articular Show more…

How does the structure of a joint play a role in its stability?How does the function of a joint play a role in its mobility?How does stability relate to mobility?

Eversion sprains produce damage to the lateral ligaments. Temporomandibular joint. Intracapsular ligaments include the ACL and PCL. Extreme ranges of motion a trade-off for lack of stability. Two synovial cavity chambers separated by an articular disc. Passive stabilizers include the anular ligament. Four sub- (e.g. subcoracoid etc.) bursae present. Talocrural joint. Coxal joint. Glenohumeral joint. Humeroulnar joint. Arterial damage entering the fovea capitis can result in necrosis. Rotator cuff acts as a dominant active stabilizer. Acetabular labrum increased the depth of the socket. Tibiofemoral joint. Lateral forces likely to cause damage to the tibial collateral ligament, ACL, and medial meniscus.
