The carpal tunnel in the wrist is formed by the interconnected carpal bones and the transverse carpal ligament (TCL). The tunnel contents include the median nerve, which is susceptible to entrapment in the space-limited tunnel leading to carpal tunnel syndrome (CTS). CTS patients have increased flattening of the median nerve which is alleviated after surgically transecting the TCL to increase c...

The carpal tunnel was investigated by high-resolution computed tomographic (CT) scanning of two cadavers, two healthy persons, and 20 patients with carpal tunnel syndrome to outline normal and pathologic anatomy. The following changes leading to median nerve compression in the carpal canal were demonstrated by CT: (1) thickening of the transverse carpal ligament with resultant decrease in the v...

Carpal tunnel syndrome, the most common entrapment neuropathy of the upper extremity, is caused by compression of the median nerve as it travels through the carpal tunnel. Classically, patients with the condition experience pain and paresthesias in the distribution of the median nerve, which includes the palmar aspect of the thumb, index and middle fingers, and radial half of the ring finger. A...

INTRoduCTIoN Carpal tunnel syndrome is a most common peripheral compression neuropathy (1). It is caused by mechanical compression of the median nerve as it traverses the carpal tunnel of the wrist. Classic signs and symptoms are numbness of the lateral three digits and weakness of the thenar muscles due to atrophy (2). Important diagnostic tests include electromyography (EMG) and nerve conduct...

A 70-year-old woman presented left hand neuropathic pain and nocturnal paresthetic brachialgia. The neurological examination was unremarkable except for positive Scratch Collapse Test (SCT) suggesting left Carpal Tunnel Syndrome (CTS) (Figure). Subsequent electromyographic evaluation was consistent with left CTS. The SCT is a new clinical maneuver for peripheral nerve compression diagnosis that...

BACKGROUND Carpal tunnel syndrome is the most common neuropathy in the upper extremity, resulting from the compression of the median nerve at wrist level. Clinical studies are essentials to present evidence on therapeutic resources use at early restoration on peripheral nerve functionality. Low-level laser therapy has been widely investigated in researches related to nerve regeneration. Therefo...

Acute median nerve compression usually occurs from increased pressure within the carpal tunnel and forearm compartments. Although the hyperesthesia from burns may mimic symptoms of acute compression neuropathy, clinical diagnosis should be made from history, clinical signs and symptoms. Early recognition and decompression of the carpal tunnel either as part of the burn excision or along with es...

Lipoma is a relatively frequent, benign soft-tissue tumor rarely located in the hand. A lipoma of the hand causing a carpal tunnel syndrome by compression of the median nerve is exceptional. We report the case of a 70-year-old female presenting with a carpal tunnel syndrome. A compression of the median nerve by a lipoma was discovered during surgery. Transverse carpal ligament release with lipo...
