The Shoulder Joint - Structure - Movement - TeachMeAnatomy
2024年10月8日 · The shoulder joint is formed by an articulation between the head of the humerus and the glenoid cavity (or fossa) of the scapula. This gives rise to the alternate name for the shoulder joint – the glenohumeral joint. Like most synovial joints, the articulating surfaces are covered with hyaline cartilage.
Shoulder Joint Tear (Glenoid Labrum Tear) - OrthoInfo - AAOS
The head of the upper arm bone (humeral head) rests in a shallow socket in the shoulder blade called the glenoid. The head of the upper arm bone is usually much larger than the socket, and a soft fibrous tissue rim called the labrum surrounds the socket to help stabilize the joint.
Shoulder joint - Wikipedia
The shoulder joint is a ball-and-socket joint between the scapula and the humerus. The socket of the glenoid fossa of the scapula is itself quite shallow, but it is made deeper by the addition of the glenoid labrum. The glenoid labrum is a ring of cartilaginous …
Glenohumeral (Shoulder) joint: Bones, movements, muscles
2023年10月30日 · The glenohumeral joint is the articulation between the spherical head of the humerus and the concave glenoid fossa of the scapula. Being a synovial joint, both articular surfaces are covered with hyaline cartilage. The glenoid fossa is a shallow pear-shaped pit on the superolateral angle of scapula. The concavity of the fossa is less acute than ...
Glenoid fossa - Wikipedia
It is a shallow, pyriform articular surface, which is located on the lateral angle of the scapula. It is directed laterally and forward and articulates with the head of the humerus; it is broader below than above and its vertical diameter is the longest. This cavity forms the glenohumeral joint along with the humerus.

2023年8月8日 · The glenohumeral articulation involves the humeral head with the glenoid cavity of the scapula, and it represents the major articulation of the shoulder girdle. The latter also includes minor articulations of the sternoclavicular (SC), acromioclavicular (AC), and scapulothoracic joints.
Glenohumeral Joint - Physiopedia
The glenohumeral (GH) joint is a true synovial ball-and-socket style diarthrodial joint that is responsible for connecting the upper extremity to the trunk. It is one of four joints that comprise the shoulder complex. This joint is formed from the combination of the humeral head and the glenoid fossa of the scapula.
Glenohumeral Joint Anatomy, Stabilizer, and Biomechanics
2022年9月9日 · the primary biomechanical role of the rotator cuff is stabilizing the glenohumeral joint by compressing the humeral head against the glenoid
Glenoid Fractures - StatPearls - NCBI Bookshelf
2023年8月4日 · The glenoid fossa can be fractured when a high-velocity blunt force causes the humeral head to impact the glenoid cavity. These fractures are typically transverse and occur along the direction of the impact of force. Glenoid avulsions and rim injuries are more common and usually occur in association with an anterior shoulder dislocation and do ...
Clinical anatomy and biomechanics of the glenohumeral joint …
2017年1月21日 · In addition, the anatomy and biomechanics are described from their functional perspective as passive and active stabilizers. The bony passive stabilizers include the glenoid, humeral head, and the proximal humerus. The soft tissue passive stabilizers include the glenoid labrum, the glenohumeral ligaments, and the glenohumeral joint capsule.
