The medial epicondyle protects the ulnar nerve, which runs in a groove on the back of this epicondyle. The ulnar nerve is vulnerable because it passes close to the surface along the back of the bone. Striking the medial epicondyle causes a tingling sensation in the ulnar nerve. This response is known as striking the "funny bone". [1]
The order of appearance can be understood by the mnemonic CRITOE, referring to the capitellum, radial head, internal epicondyle, trochlea, olecranon, and external epicondyle at ages 1, 3, 5, 7, 9 and 11 years. These apophyseal centers then fuse during adolescence, with the internal epicondyle and olecranon fusing last.
The medial epicondyle of the femur is an epicondyle, a bony protrusion, located on the medial side of the femur at its distal end. Located above the medial condyle , it bears an elevation, the adductor tubercle , [ 1 ] which serves for the attachment of the superficial part, or "tendinous insertion", of the adductor magnus . [ 2 ]
The trochlea has the capitulum located on its lateral side and the medial epicondyle on its medial. It is directly inferior to the coronoid fossa anteriorly and to the olecranon fossa posteriorly. In humans, these two fossae, the most prominent in the humerus, are occasionally transformed into a hole, the supratrochlear foramen , [ 2 ] which is ...
The medial intermuscular septum, is thicker than the lateral intermuscular septum. It extends from the lower part of the crest of the lesser tubercle of the humerus below the teres major , and passes along the medial supracondylar ridge to the medial epicondyle ; it is blended with the tendon of the coracobrachialis , and gives attachment to ...
Golfer's elbow, or medial epicondylitis, is tendinosis (or more precisely enthesopathy) of the medial common flexor tendon on the inside of the elbow. [1] It is similar to tennis elbow , which affects the outside of the elbow at the lateral epicondyle.
Head of radius and medial epicondyle of the humerus starts to ossify at 4 to 5 years of age, followed by trochlea of humerus and olecranon of the ulna at 8 to 9 years of age, and lateral epicondyle of the humerus to ossify at 10 years of age. [3]
Osborne's ligament, also Osborne's band, Osborne's fascia, Osborne's arcade, arcuate ligament of Osborne, or the cubital tunnel retinaculum, refers to either the connective tissue which spans the humeral and ulnar heads of the flexor carpi ulnaris (FCU) or another distinct tissue located between the olecranon process of the ulna and the medial epicondyle of the humerus.
