Anatomical variations of pronator teres muscle: predispositional role for nerve entrapment☆
OBJECTIVE To assess the anatomical variations of the pronator teres muscle (PTM) and its implication in the compression of the median nerve, which passes through the humeral and ulnar heads of the PTM. METHODS For the present study, 100 upper limbs from human cadavers from the anatomy laboratory were dissected. Forty-six specimens were male and four, female, whose aged ranged from 28 to 77 ye...
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 کاملThe pronator teres syndrome: compressive neuropathy of the median nerve.
Thirty-nine patients with a clinical diagnosis of the pronator teres syndrome were seen during a seven-year period. They typically complained of aching discomfort in the forearm, weakness in the hand, and numbness in the thumb and index finger. Cyclic stress usually brought on the symptoms. The distinctive physical finding was tenderness over the proximal part of the pronator teres, which was a...
متن کاملVariability 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 کاملANATOMICAL VARIATIONS OF THE CHORDA TYMPANI NERVE
The author studied anatomical variations of the origin of the chorda tympani nerve from the mastoid portion of the facial nerve. The studies were performed on 200 specimens of human temporal bone. It was found that the chorda tympani may arise from the facial nerve in three levels: most commonly from the mid third of its mastoid segment (70%), less commonly from the proximal third (20%), an...
