Struthers' ligament and associated median nerve variations in a cadaveric specimen.
نویسندگان
چکیده
A Ligament of Struthers has been identified and studied in a cadaveric arm. Its relationships to a rudimentary supracondylar process, the pronator teres muscle, the median nerve, and the medial epicondyle of the humerus are described. Compared to an extensively studied series of normals, the ligament in this case was associated with abnormally proximal branching of the median nerve, a finding which is surgically significant and not addressed in the literature to date.

Anatomic Variations of Brachial Plexus: A Cadaveric Study
Introduction: The brachial plexus is responsible for the innervation to the upper limb and some parts of the thorax. Variations in the branching of the brachial plexus are common and have been reported in 65.3% of the population. The variations (Atypical communication) of brachial plexus have significant clinical and surgical importance. Methods: In this study 10 upper limbs which belonged...
متن کاملUnusual high-origin of the pronator teres muscle from a Struthers' ligament coexisting with a variation of the musculocutaneous nerve.
During routine anatomical dissection of the right upper extremity of a 53-year-old woman cadaver, an unusual high-origin of the pronator teres muscle was discovered. The fibers of the aberrant muscle arose from two bone origins--the medial epicondyle and a small supracondylar process of the humerus, and from a tendinous arch (Struthers' ligament) extending between them. In addition, there was a...

OBJECTIVE The objective of this study was to determine the frequency and anatomical characteristics of Struthers' ligament and the supracondylar humeral process and evaluate the clinical implications in compressive neuropathy of the median nerve . METHOD We dissected 60 arms from 30 cadavers (26 males and 4 females): 15 were previously preserved in formalin and glycerin and 15 were dissected ...

متن کاملMedian nerve compression by Struthers ligament.
A 61-year-old patient presented with progressive weakness, pain and numbness in the left arm and hand. On examination the abnormalities were confined to the distribution of the median nerve, and electrophysiological testing localised the lesion to the segment just proximal to the elbow. At surgery Struthers ligament was found compressing the median nerve. No bony spur was found by palpation or ...
