Since the capitellum was intact and displacement of fracture fragment was anterior, antero-medial approach through the interval between flexor pronator muscles medially and the brachialis
muscle laterally was utilized.
In 10% of cases a third head arises from the superomedial part of brachialis
and is attached to the bicipital aponeurosis, which descends medial side of the tendon of insertion .
In the middle of the arm median nerve crosses from lateral to medial side in front of the brachial artery and accompanies it lying medially .In the cubital fossa the nerve passes beneath the bicipital aponeurosis and lies above brachialis
Prior cadaveric shoulder rotator experiments showed that 90Adeg of external shoulder rotator abduction creates instability due to a lack of participation by the biceps brachialis
, coracobrachialis, anterior deltoid, major pectoral, and subscapularis, all of which could favour stabilisation of the glenohumeral girdle.21 Furthermore, the ER are susceptible to major fatigue, which could be a source of variability during strength generation tests.22 Stabilisation straps typically increases reliability in strength as shown in related studies.23 FED does not have its own stabilisation straps.
Dorsal wall of trunk-armour embayed anteriorly to accommodate head; tergal angle situated far forward; anterior median dorsal plate with breadth/length index between 100 and 128; pectoral articulation subcephalic; funnel pit of processes brachialis
in anterior ventro-lateral very small; pars pedalis under angle to longitudinal body axis.
(22) As mentioned before, the anterior capsule and brachialis
are thin and atrophic in rheumatoid arthritis and offer less protection to the median nerve and its branches.
Localization of motor entry points and terminal intramuscular nerve endings of the musculocutaneous nerve to biceps and brachialis
In all other upper limbs normal course of musculocutaneous nerve was seen on dissection, in which musculocutaneous nerve were piercing coracobrachialis of its respective side and giving branch to coracobrachialis, biceps brachii and brachialis
muscles (Figure 2).

fuer die operation en an der oberen extremitat" [Anesthesia of the brachial plexus for operations on the upper extremity].
In order to reduce the occurrence of triceps related complications even further, Pierce and Herndon (61) advocated a triceps-sparing approach that utilizes a medial window between the triceps and the brachialis
and a lateral window between the triceps and the mobile wad of Henry.
The radial nerve supplies sensitive innervation to the postero-lateral skin of upper limbs and motor innervation to triceps brachialis
