Besides, the dorsoepicondylar medial muscle is described in comparative anatomy as being common to all quadruped mammals (Leche, 1900, apud Haninek et al., 2009), in which it is in complete form, that is, detached from the lower anterior edge of the latissimus dorsi muscle near its insertion tendon, passing like an arch through the axilla and descending into the arm in the plane of the medial intermuscular septum, where it ends inserted in the medial epicondyle
of the humerus (Haninec et al.).
An anatomic descriptive study of 171 plain films of normal distal humeri of children aged 4 to 15 years demonstrated that the average location of the center of the intact medial epicondyle
on AP radiographs is 0.5 mm below the olecranon fossa line and 1.2 mm anterior to the posterior humeral line in lateral radiographs.
(14) reported a FCUM that possessed only a humeral head; another muscle belly originating from medial epicondyle
lying between flexor digitorum superficialis and FCUM and was attached to triquetral, hamate bones, and flexor retinaculum.
Plain radiography and computed tomography at three months after the injury showed that the avulsion fracture of the lateral epicondyle
became displaced and malunited, the radiohumeral joint had widened on the anteroposterior view, and the posterior subluxation of the radial head had widened on the lateral view (Figures 2(a)-2(e)).
There is electrophysiologic evidence on this examination of a severe right ulnar nerve mononcuropathy at the elbow proximal to the olecranon/medial epicondyle
and proximal to the innervation of the right FCU; axonal greater than dcmyclinating neuropathic process affecting motor and to a lesser extent sensory fibers; and a mixture of acute and chronic denervation in the right 1st Dl, ADM, and FCU.

A line was drawn between lateral epicondyle
and distal radioulnar joint.
At first, the acromion process, lateral epicondyle
of the humerus and the middle part of wrist were identified and the longitudinal axes of arm and forearm were determined.
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.
Now, one K-wire was put from below the lateral epicondyle
across the fracture line into proximal fragment obliquely so as to engage the medial cortex of the proximal fragment, and the second K-wire was put from below the medial epicondyle
across the fracture into the proximal fragment so as to engage the lateral cortex.
For radio-ulnar fracture incision from medial epicondyle
of humerus to styloid process of radius.
