The anterior ligament of the elbow is a broad and thin fibrous layer covering the anterior surface of the joint.. It is attached to the front of the medial epicondyle and to the front of the humerus immediately above the coronoid and radial fossae below, to the anterior surface of the coronoid process of the ulna and to the annular ligament, being continuous on either side with the collateral ...
The composition of the triangular ligamentous structure on the lateral side of the elbow varies widely between individuals [1] and can be considered either a single ligament, [2] in which case multiple distal attachments are generally mentioned and the annular ligament is described separately, or as several separate ligaments, [1] in which case parts of those ligaments are often described as ...
The humeroulnar joint (ulnohumeral or trochlear joint [1]) is part of the elbow-joint. It is composed of two bones, the humerus and ulna, and is the junction between the trochlear notch of ulna and the trochlea of humerus. [1] It is classified as a simple hinge-joint, which allows for movements of flexion, extension and circumduction.
Acute or chronic disruption and/or attenuation of the ulnar collateral ligament often result in medial elbow pain, valgus instability, and impaired throwing performance. There are both non-surgical and surgical treatment options.
The quadrate ligament reinforces the inferior part of the capsule of the elbow joint [1] and contributes to joint stability by securing the proximal radius against the radial notch and by restricting excessive supination (10–20° restriction) and, to a lesser degree, pronation (5–8°).
An elbow engine is a piston-based steam engine typically fed by steam or compressed air to drive a flywheel and/or mechanical load. It is based on a mechanism known as a Hobson's joint . Although not commonly used today for practical purposes, it is still built by hobbyists for its rarity and unconventionality.
From late 2016 onwards, every Bandai produced model kit, including Gunpla, were made with Japanese and English text on the box and manuals. In 2017, Bandai began the Gundam Evolution Project, which sought to improve Gunpla technology with various groundbreaking kits, such as the adoption of a new joint system or a new LED system for large-scale ...
Elbow fractures are any broken bone in or near the elbow joint and include olecranon fractures, supracondylar humerus fractures and radial head fractures. [1] The elbow joint is formed by three different bones: the ulna, radius, and humerus that permit the joint to move like a hinge and allow a person to straighten and bend their arm and these bones are connected by tendons, ligaments, and ...
