The oblique cord is a ligament between the ulnar and radius bones in the forearm near the elbow.It takes the form of a small, flattened band, extending distally and laterally, from the lateral side of the ulnar tuberosity at the base of the coronoid process to the radius a little below the radial tuberosity.

A harvested tendon, such as the palmaris tendon [11] from the forearm of the same or opposite elbow, the patellar tendon, hamstring, toe extensor or a donor's tendon , is then woven in a figure-eight pattern through the holes and anchored. [10] The ulnar nerve is usually moved to prevent pain, as scar tissue can apply pressure to the nerve. [11]
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 olecranon (/ oʊ ˈ l ɛ k r ə n ɒ n /, from Greek olene 'elbow' and kranon 'head'), is a large, thick, curved bony process on the proximal, posterior end of the ulna.It forms the protruding part of the elbow and is opposite to the cubital fossa or elbow pit (trochlear notch).
The joint capsule of the elbow attaches to the humerus just proximal to the olecranon fossa. [3] [4] ... Photo of model at Waynesburg College skeleton3/olecranonfossa;
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°).
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 ...
