2023年11月2日 · Like all synovial joints, the elbow joint has a capsule enclosing the joint. This is strong and fibrous, strengthening the joint. The joint capsule is thickened medially and laterally to form collateral ligaments, which stabilise the flexing and extending motion of the arm.

Because of the proximity of several ligaments, aponeuroses, and capsule in the limited area of the elbow joint, the precise anatomy is difficult to understand. In the current narrative review, we focused on two anatomical perspectives: the capsular attachment and …

2023年9月11日 · The elbow joint is a synovial joint found in the upper limb between the arm and the forearm. It is the point of articulation of three bones: the humerus of the arm and the radius and the ulna of the forearm. The elbow joint is classified structurally as a synovial joint.

The elbow joint is covered by a synovial membrane, which is surrounded by a joint capsule. The joint capsule extends from the margins of the articular surfaces of the capitulum and trochlea on the humerus, to the coronoid process anteriorly; and to the olecranon fossa posteriorly.

The anterior joint capsule is usually thinner and more transparent. It remains under tension when the elbow is extended and relaxes when the elbow is flexed. The greatest capacity of the joint capsule is 30–35 ml at 80° of flexion, when it is fully distended.

2017年10月8日 · Describe the capsule and ligaments of elbow joint. Fibrous Capsule : It is lax and thin anteriorly to allow the flexion and extension movements and is strengthened on either side by the collateral ligaments. Above it is attached to the medial epicondyle, margins of coronoid, radial and olecronon fossa, and lateral epicondyle.

2023年2月1日 · The stress distribution and transfer of the joint capsule, ulnar cartilage, and ligaments were obtained under different injuries and flexion angles, to explore the influence of capsule injures on the stability of the elbow joint.

The elbow joint is one of the most complex joints in the human body as it incorporates 3 articulations within its joint capsule, namely the ulno-humeral joint, radio-capitellar joint and the proximal radio-ulnar joint.

These bones connect the wrist to the elbow forming the bottom portion of the hinge joint. The elbow joint is actually three separate joints surrounded by a watertight sac called a joint capsule. This capsule surrounds the elbow joint and contains lubricating fluid called synovial fluid.

2016年8月28日 · JOINT CAPSULE. The anterior capsule inserts proximally above the coronoid and radial fossae . Distally, the capsule attaches to the anterior margin of the coronoid medially as well as to the annular ligament laterally. Posteriorly, the capsule attaches just above the olecranon fossa, distally along the supracondylar bony columns.
