Understanding of the anatomy of the radial nerve and its branches is vital to the treatment of humeral fracture or the restoration of upper extremity function. In this study, we dissected 40 upper extremities from adult cadavers to locate the course of the radial nerve and the origins and insertions of the branches of the radial nerve using surface landmarks. The radial nerve reached and left the radial groove and pierced the lateral intermuscular septum, at the levels of 46.7, 60.5, and 66.8% from the acromion to the transepicondylar line, respectively. Branches to the long head of the triceps brachii originated in the axilla, and branches to the medial and lateral heads originated in the axilla or in the arm. The muscular attachments to the long, medial, and lateral heads were on average 34.0 mm proximal, 16.4 mm distal, and 19.3 mm proximal to the level of inferior end of the deltoid muscle, respectively. The radial nerve innervated 65.0% of the brachialis muscles. Branches to the brachioradialis and those to the extensor carpi radialis longus arose from the radial nerve above the transepicondylar line. Branches to the extensor carpi radialis brevis usually arose from the deep branch of radial nerve (67.5%); however, in some cases, branches to the extensor carpi radialis brevis arose from either the radial nerve (20.0%) or the superficial branch of the radial nerve (12.5%). Using these data, the course of the radial nerve can be estimated by observing the surface of the arm. Clin. Anat. 26:862–869, 2013. © 2012 Wiley Periodicals, Inc.  相似文献

The objectives of the study are to demonstrate the innervation patterns of the triceps muscles and the most suitable branch of the radial nerve for nerve transfer to restore the motor function of the deltoid muscle in patients with complete C5–C6 root injury. Seventy‐nine arms (40 left arms and 39 right arms) from 46 embalmed cadavers (24 male and 22 female) were included in the study. The nerves to the triceps were dissected from the triceps muscles (long head, lateral head, and medial head). The lengths of the branches were measured from the main trunk. The distance from the inferior margin of the teres major muscle to the origin of the nerve to the long head, lateral head, and medial head of the triceps were recorded as well. The first branch was the nerve to the long head of the triceps in 79 arms (100%). The second branch was the nerve to the upper medial head in 30 arms (38%), nerve to the medial head in 8 arms (10.1%), nerve to the upper lateral head in 35 arms (44.3%) and nerve to the lateral head in 6 arms (7.6%). The patterns of branches to the triceps were classified according to our dissections. The nerve to the long head of the triceps was constant as the first branch of the nerve to the triceps branch of the radial nerve in the vicinity of the inferior margin of the teres major muscle.

In a routine dissection of the axillary fossa, a muscle originating from the coracoid process of the scapula and extending to the long head of triceps brachii muscle was observed. The mentioned muscle was adhering to both the triceps brachii muscle and the tendinous part of the latissimus dorsi muscle. This anatomical variation is referred to as axillary arch (Langer's muscle or axillopectoral muscle). The muscle mass was measured 9.6 cm in length and 1.4 cm in width. The accessory muscle can be a reason of an axillary mass and can exert pressure on the neighboring neurovascular bundle or lymph routes; thus, exposing a wide range of symptoms. Therefore, variations of this area should be kept in mind in surgical interventions.  相似文献

An unusual bilateral variation in the arterial pattern of the axilla was observed in an embalmed cadaver. Each axilla contained two axillary arteries of similar origins but different patterns of branching and fate. The first part of each axillary artery was a single vessel as is the norm. It gave off a supreme thoracic artery and then bifurcated into two medium-sized arteries hence referred to as regular and variant. The variant artery ran in an antero-medial course, partly covered by the one axillary vein. The regular artery gave off the thoracoacromial and two posterior branches from its second part, the anterior and posterior humeral circumflex arteries from its third part, and then continued as the brachial artery with all the usual branches except the profunda brachii on the right side. The variant gave off five arteries from the second part, a thoracoacromial artery, two separate long thoracic arteries each with a branch that ran along the intercostobrachial nerve to the arm, and two posterior branches. In the third part of the variant, the subscapular artery arose with its usual branches plus a common origin for two additional humeral circumflex arteries. The variant terminated as the profunda brachii artery to the right side while on the left side it terminated in muscular branches to the triceps. Hence, the arterial blood supply to the upper limb, and the axillary region in particular, was shared on both sides by two major arteries instead of one. These two arteries emanated from the first part of the axillary artery and may represent persisting branches of the capillary plexus of the developing limb buds. The findings have an embryological basis and clinical relevance considering the frequency of procedures in this region.  相似文献
