Motor Branch Biopsy of the Pronator Teres Muscle in a Patient with Painful Forearm Neuropathy
نویسندگان
چکیده
Histological evaluation of a peripheral nerve is often the final diagnostic work-up for a neuropathy of unknown origin, and a distal sensory nerve is usually biopsied. Here, we report the case of a female patient with painful unilateral neuropathy in the upper arm. According to the histological evaluation of the pronator teres motor branch, vasculitis seemed to be the most probable cause of the condition, and steroid therapy improved the patients' symptoms. A biopsy of the motor branch of the pronator teres muscle nerve may be considered a valuable diagnostic option in selected cases with neuropathy affecting the upper limb, when performed in cooperation with neurologists and orthopedic surgeons.

Additional muscle slips from the bicipital aponeurosis and a long communicating branch between the musculocutaneous and the median nerves
Introduction Pronator teres usually originates as two heads, the superficial humeral head from medial epicondyle and the deep ulnar head from the coronoid process. The median nerve passes between the two heads, and the ulnar artery passes deep to the deep head of the pronator teres in the cubital fossa. Flexor carpi radialis, another superficial flexor of the forearm arises from common flexor o...

The clinical and electrophysiological picture of seven patients with the pronator syndrome is contrasted with other causes of median nerve neuropathy. In general, these patients have tenderness over the pronator teres and weakness of flexor pollicis longus as well as abductor pollicis brevis. Conduction velocity of the median nerve in the proximal forearm is usually slow but the distal latency ...
متن کاملPrimary writing tremor.
We describe a patient who complained of jerking of the right forearm on writing. Active pronation of his arm produced several beats of pronation/supination tremor. A burst of tremor also could be elicited by tendon taps to the volar surface of the wrist, to the finger extensors, and to pectoralis major, and by forcible supination of the wrist delivered by a torque motor. The subject's writing d...

We present a case of a torn pronator teres muscle of the right forearm that occurred following prolonged batting during recreational cricket. Previous reports of cricket injuries to batsmen describe phalanx fractures due to direct ball impact. However, we could find no prior reports of pronator teres or other upper-extremity muscle injury. Our patient demonstrated a high-grade tear to the prona...
متن کاملMechanical evaluation of the Pronator Teres rerouting tendon transfer.
We simulated pronator teres rerouting using a three-dimensional biomechanical model of the arm. Simulations comprised the evaluation of changes in muscle length and the moment arm of pronator teres with changes in forearm axial rotation and elbow flexion. The rerouting of Pronator Teres was simulated by defining a path for it through the interosseous membrane with re-attachment to its original ...
