Furthermore, Koornneef reported that the thinnest intermuscular septum was in the superotemporal region.
In the course of its development, the arch of the muscular primordium that crosses the axilla and continues as the medial intermuscular septum of the arm is interrupted and disappears, presumably by apoptosis, its remnants constituting the dorsoepicondylar medial muscle in its different types of presentation (Shah et al.), such as the chondroepitrochlear, chondrohumeral and pectorodorsal muscles (Loukas & Tubbs).
The proximal medial portal is located 2 cm proximal to the medial humeral epicondyle and slightly anterior to the intermuscular septum. The trochar is aimed toward the radiocapitellar joint and passes the ulnar nerve which is within the vicinity; the nerve should be protected as long as the surgeon stays anterior to the septum.
The belly on the medial aspect was larger and was arising from the medial margin of the olecranon process, proximal two thirds of posterior border of ulna, an aponeurosis which is common for FCU, extensor carpi ulnarismuscle and flexor digitorum profundus muscle and intermuscular septum between it and flexor digitorum superficialis muscle.
The ulnar head has an extensive origin from the medial margin of the olecranon process and proximal two-thirds of the posterior border of the ulna, an aponeurosis (which it shares with the extensor carpi ulnaris and flexor digitorum profundus), and from the intermuscular septum between it and flexor digitorum superficialis.
