Triceps Brachii Muscle demonstrating a fourth head
Clinical Anatomy, 2006Co-Authors: Shane R Tubbs, George E Salter, Jerry W OakesAbstract:Variations of the Triceps Brachii Muscle are apparently rare. We report an additional attachment site of the medial head of the Triceps Brachii found on the left side of a male cadaver. This head originated from the posterior aspect of the surgical neck of the humerus. Clinicians diagnosing or treating patients with weakness or pain of the posterior arm should consider anomalous Muscles in this region that may result in neurovascular compression.

surgical anatomy of the axillary nerve within the quadrangular space
Journal of Neurosurgery, 2005Co-Authors: Shane R Tubbs, Alan C Aikens, Justin P Martin, Leslie L Weed, George E Salter, Elizabeth C Tylerkabara, Jerry W OakesAbstract:Object. There is a paucity of literature regarding the surgical anatomy of the quadrangular space (QS), which is a potential site of entrapment for the axillary nerve. Muscle hypertrophy of this geometrical area and fascial bands within it have been implicated in compression of the axillary nerve. Methods. Fifteen human cadavers (30 sides) were dissected for this study. Measurements of the QS and its contents were made. The mean height of this space was 2.5 cm and the mean width 2.5 cm; its mean depth was 1.5 cm. The axillary nerve was always the most superior structure in the space, and in all cases the nerve and artery hugged the surgical neck of the humerus just superior to the origin of the lateral head of the Triceps Brachii Muscle. This arrangement placed the axillary nerve in the upper lateral portion of the QS in all cadaveric specimens. The nerve branched into its muscular components within this space in 10 sides (33%) and posterior to it in 20 sides (66%). The cutaneous component of the axillary nerve branched from the main trunk of the nerve posterior to the QS in all specimens. Fascial bands were found in this space in 27 (90%) of 30 sides. Conclusions. Knowledge of the anatomy of the QS may aid the surgeon who wishes to explore and decompress the axillary nerve within this geometrical confine.

ulnar nerve innervation of the medial head of the Triceps Brachii Muscle a cadaveric study
Clinical Anatomy, 2013Co-Authors: Marios Loukas, Shane R Tubbs, Sharath S Bellary, Neslihan Yuzbasioglu, Mohammadali Mohajel Shoja, Robert J SpinnerAbstract:Although the ulnar nerve is closely associated with the Triceps Brachii Muscle, the literature does not normally describe it as supplying this Muscle. However, recent research has examined the ulnar nerve in the upper arm and identified branches supplying the medial head of the Triceps Brachii Muscle. This study aims to expand upon this research by describing the course and incidence of these branches in a larger sample size. We examined 50 specimens in 25 cadavers. Ulnar innervation of the medial head of the Triceps Brachii was identified in 14 specimens (28%). The mean distance of the ulnar nerve branch midpoint was 26% along a line between the surgical neck and an epicondyle line, with a range of 11–39%. Innervation of the Triceps Brachii Muscle by the ulnar nerve has important clinical and surgical implications. Clin. Anat. 26:1028–1030, 2013. © 2013 Wiley Periodicals, Inc.

the first experience of triple nerve transfer in proximal radial nerve palsy
World Neurosurgery, 2018Co-Authors: Mohammadreza Emamhadi, Sasan AndalibAbstract:Background Injury to distal portion of posterior cord of brachial plexus leads to palsy of radial and axillary nerves. Symptoms are usually motor deficits of the deltoid Muscle; Triceps Brachii Muscle; and extensor Muscles of the wrist, thumb, and fingers. Tendon transfers, nerve grafts, and nerve transfers are options for surgical treatment of proximal radial nerve palsy to restore some motor functions. Tendon transfer is painful, requires a long immobilization, and decreases donor Muscle strength; nevertheless, nerve transfer produces promising outcomes. We present a patient with proximal radial nerve palsy following a blunt injury undergoing triple nerve transfer. Case Description The patient was involved in a motorcycle accident with complete palsy of the radial and axillary nerves. After 6 months, on admission, he showed spontaneous recovery of axillary nerve palsy, but radial nerve palsy remained. We performed triple nerve transfer, fascicle of ulnar nerve to long head of the Triceps branch of radial nerve, flexor digitorum superficialis branch of median nerve to extensor carpi radialis brevis branch of radial nerve, and flexor carpi radialis branch of median nerve to posterior interosseous nerve, for restoration of elbow, wrist, and finger extensions, respectively. Conclusions Our experience confirmed functional elbow, wrist, and finger extensions in the patient. Triple nerve transfer restores functions of the upper limb in patients with debilitating radial nerve palsy after blunt injuries.
