“…The mean humerus length was 287 mm, which was similar to the 302 mm reported by Guse and Ostrum [13]. The mean distance from the acromion to the upper margin was 147 mm and the mean distance to the lower margin was 195 mm (Line B).…”

“…The middle points of the acromion, the medial epicondyle, and the lateral epicondyle were used as bony landmarks. In addition, the techniques described by Guse and Ostrum [13] were used as the basis for measurements of the radial nerve in relation to the surrounding skeleton ( Fig. 1; Table 1): (1) Line A, from the acromion to the upper margin; (2) Line B, from the acromion to the lower margin; (3) Line C, from the medial epicondyle to the lower margin; (4) Line D, from the medial epicondyle to the upper margin; (5) Line E, from the lateral epicondyle to the lower margin; and (6) Line F, between the acromion and the lateral epicondyle (defined as humeral length).…”

“…The radial nerve crosses the posterior aspect of the humerus near its midpoint [13]. The site at which the nerve is most vulnerable to damage is near the junction of the middle and distal thirds of the humerus, as Holstein and Lewis [15], Bodner et al [4], and Edwards and Kurth [11] have described.…”

We analyzed anatomic distribution of the radial nerve in the upper arms in Chinese-adult embalmed cadavers (120 nerves in 60 cadavers) and compared it with findings reported for Caucasian adults. The acromion, the medial epicondyle, and the lateral epicondyle were used as bony landmarks. We used previously described techniques to quantitatively describe the location of the radial nerve in relation to the surrounding skeleton. Courses of the radial nerve relative to the humeral shaft in Chinese subjects differed from those previously reported for Caucasian subjects. The parameters that differed from Caucasians were: the distances from the acromion to the upper margin (147 ± 21 mm versus 124 ± 12 mm), the acromion to the lower margin (195 ± 36 mm versus 176 ± 17 mm), and the medial epicondyle to the lower margin (111 ± 21 mm versus 131 ± 10 mm). Our study provides information to help identify the radial nerve during surgery and elucidates racial differences in the distribution of the radial nerve between Chinese and Caucasian populations.

“…The triceps brachii has been recognized as receiving motor innervation from the radial nerve with contributions from C7 and C8, although studies have noted the branching pattern to be inconsistent [4,5]. The specific origins of radial innervation for each of the three heads of the triceps have been described [9,10].…”

The presence of a separately innervated muscle unit of the triceps may have possible surgical importance and can be used for motor reconstructions. The ulnar nerve is closely situated to the triceps muscle and rarely examined above the elbow. The aim of this cadaveric study was to explore a possible contribution of the ulnar nerve to motor innervation of the medial head of the triceps. We dissected 18 limbs from axillae to midforearm. The path of the ulnar nerve was followed, and examination was conducted of attachments to the triceps. Gross photographs were taken and samples histologically stained. Seventeen limbs had ulnar nerve branches proximal to the epicondyles that inserted on the medial head. Eleven of these branches were from the ulnar nerve trunk. The other six were nerve branches from the ulnar collateral branch of the radial nerve. The ulnar nerve and the ulnar collateral branch of the radial nerve are previously unrecognized sources of innervation of the medial head of the triceps brachii. These motor branches must be carefully preserved during the medial surgical approach above the elbow. The ulnar innervated part of the medial head of the triceps muscle may be used like an independent motor unit.

One‐third, two‐thirds: Relationship of the radial nerve to the lateral intermuscular septum in the arm

et al. 2003

The radial nerve penetrates the lateral intermuscular septum of the arm before dividing into deep and superficial branches. It may be encountered in both anterior and posterior approaches to the humerus. An ability to accurately predict the point at which the nerve pierces the septum would be valuable during surgery in the arm, and would facilitate planning an approach to exploring the radial nerve after fractures of the distal humeral shaft. It would, in particular, make minimally invasive surgical techniques less dangerous. We dissected 20 cadaver upper limbs to establish whether the radial nerve enters the anterior compartment of the arm at a predictable level. We found that in almost every case the radial nerve entered the anterior compartment at a point within 5 mm of the junction of the distal and middle thirds of a line joining the lateral epicondyle of the humerus to the most lateral point of the acromion process of the scapula. This has not previously been described, and we believe is a useful aide-de-memoir to predicting the level at which the radial nerve penetrates the lateral intermuscular septum.
