In this part, the tendon also related laterally to the ulnar nerve and the recurrent anterior ulnar vessels until its insertion into the medial epicondyle of the humerus
The muscle group responsible for forearm flexion and pronation (pronator teres, PT; flexor digitorum superficialis muscle, FDS; flexor carpi radialis muscle, FCR; FCU; and palmaris longus muscle, PL) originates from the medial epicondyle of the humerus
and supports the motion of elbow flexion .
Seven markers were taken as following: drawing a line from the medial epicondyle of the humerus
to the apex of olecranon, marking the midpoint of this line, from this midpoint six stimulation markers were placed, respectively, along the course of the ulnar nerve at 2 cm intervals.
Ulnar nerve is prone to injuries due to its anatomical topography, especially at the elbow, where it passes behind the medial epicondyle to the groove between olecranon and the medial epicondyle of the humerus
. The so-called ulnar groove is located just behind the medial epicondyle of the humerus
, at the entrance to the cubital tunnel--the next site of the possible ulnar nerve injury.
This can be seen dynamically on ultrasound with flexion and extension at the elbow with the ulnar nerve snapping medially over the medial epicondyle of the humerus
Abduct the little finger and look for the contraction of the FCU; its contraction can usually be seen at its distal tendon, more proximally at its belly, and at its proximal tendon near the medial epicondyle of the humerus
. Once seen, now palpate for its contraction while the little finger is abducting.
Sahni et al examined both elbow and wrists of 149 females of Chandigarh (age group 11-19 Y) and reported that if the epiphysis of the medial epicondyle of the humerus
not fused, the age of the girl would be <16 years.
Un-United Medial Epicondyle of the Humerus
: Radiographic Prevalence and Association with Elbow Osteoarthritis in a Cohort of Labrador Retrievers.
It then descended superficial to the muscles arising from medial epicondyle of the humerus
and was covered by the deep fascia of the forearm, pierced the deep fascia proximal to the wrist, crossed the flexor retinaculum, and formed the superficial palmar arch.
Reconstruction generally entails fixing a tendon graft through bone tunnels in the medial epicondyle of the humerus
and sublime tubercle of the ulna to reestablish valgus stability.
Finally, it inserted onto the medial epicondyle of the humerus
near the common origin of flexors of forearm.
