Proximal compression or neuropathy of the median nerve is rare compared with carpal tunnel syndrome but recognition and management of these conditions is important. Pronator syndrome refers to compression of the median nerve around the elbow, which may present with pain in the forearm and paraesthesia in the hand. Anterior interosseous syndrome (palsy) can result from mechanical compression or ...

The anterior interosseous nerve is a branch of the median nerve. It arises from the median nerve just distal to the antecubital fossa, about 5.5 cm distal to the medial epicondyle of the humerus. [2] It passes along the interosseous membrane between the ulna and radius. It terminates in the pronator quadratus muscle around the level of the wrist. It is largely a motor nerve. It supplies the fle...

PURPOSE This study was conducted to determine the effects of 5 different finger rest positions: opposite arch, standard intraoral, basic extraoral, cross arch, and finger on finger on the muscle activity of 4 forearm muscles (extensor carpi radialis longus, flexor carpi ulnaris, biceps brachii, and pronator teres) during a simulated periodontal scaling experience. METHODS A convenience sample...

Cysticercosis is a common human infestation in the developing world. Neurocysticercosis is the most common clinical presentation of cysticercal infestation in the human body, but it may be rarely encountered in other body parts like skeletal muscle, subcutaneous tissue and eye. We report this case of an uncommon clinical presentation of soft tissue cysticercosis as an isolated forearm swelling....

BACKGROUND Medial epicondylitis of the elbow, an overuse injury characterized by angiofibroblastic tendinosis of the common flexor-pronator origin, generally responds to nonoperative treatment. Refractory cases may require surgical débridement and repair. This study discusses physical examination and imaging findings and an updated surgical technique used in patients with recalcitrant medial ep...

Background: The etiology and treatment of spontaneous paralysis variants of anterior interosseous nerve (AIN) syndrome remains controversial. Variation and multiple sites of potential compression complicate the successful performance of neurolysis. This anatomic study of the AIN and sites of potential compression in the proximal forearm facilitates critical steps involved in neurolytic procedur...

Twenty canine elbows were examined by low-field MRI. The objective of this study was to compare five magnetic resonance sequences: High Resolution Gradient Echo in the sagittal plane, XBONE T2 in the sagittal plane, Spin Echo T1 in the sagittal plane, Spin Echo T1 in the dorsal plane and 3D SST1 and XBONE T1 in the transverse plane, and to determine which sequences have the highest diagnostic v...

Carpal tunnel syndrome (CTS) is by far the most common cause of median nerve damage. The carpal tunnel is an anatomical compartment of the hand; it is bounded on three sides by carpal bones which form an arch, and on the palmar side by the transverse carpal ligament. Pathogenesis CTS results from compromise of median nerve function at the wrist, caused by increased pressure in the carpal tunnel...
