Variability of the pronator teres muscle and its clinical significance.
While investigating the cause of entrapment syndrome of the peripheral nerves in the elbow region, we observed variability of the pronator teres muscle and the relationship of this muscle to the median nerve and the surrounding vessels. Attention was also paid to the occurrence of the supracondylar process of the humerus and Struthers' ligament with regard to their ontogenetic and phylogenetic ...
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...
متن کاملPronator teres is an appropriate donor muscle for restoration of wrist and thumb extension.
OBJECTIVE To compare the detailed architectural properties of the pronator teres (PT), extensor carpi radialis brevis (ECRB), and extensor pollicis longus (EPL) muscles to evaluate the suitability of PT-to-ECRB and PT-to-EPL surgical procedures. METHODS Muscle physiologic cross-sectional areas and region-specific muscle fiber lengths were measured in cadaveric PT, ECRB, and EPL muscles (n = 1...
متن کاملAnatomical variations of the pronator teres muscle in a Central European population and its clinical significance
The pronator teres (PT) muscle is a forearm flexor with radial and ulnar heads. It is innervated by the median nerve (MN), which passes between these heads. Nerve entrapment, known as "PT syndrome", may occur in this passage. Anatomical variations in this region may be potential risk factors of this pathology. Therefore, the aim of the study was to determine the relationship between morphologic...
متن کاملEarly Surgical Treatment of Pronator Teres Syndrome
We report a rare case of pronator teres syndrome in a young female patient. She reported that her right hand grip had weakened and development of tingling sensation in the first-third fingers two months previous. Thenar muscle atrophy was prominent, and hypoesthesia was also examined on median nerve territory. The pronation test and Tinel sign on the proximal forearm were positive. Severe pinch...
