Guyon's canal syndrome is a compression neuropathy of the ulnar nerve entrapment at the wrist. Compression of the ulnar nerve at the wrist by a ganglion, lipomas, diseases of the ulnar artery, fractures of the hamate and trauma are common etiologcal factors. Unlike Guyon's canal syndrome, carpal tunnel syndrome (CTS) is the most common nerve entrapment of the upper extremity. Although, open (OC...

Carpal tunnel syndrome (CTS) is a common focal peripheral neuropathy. Increased pressure in the carpal tunnel results in median nerve compression and impaired nerve perfusion, leading to discomfort and paresthesia in the affected hand. Surgical division of the transverse carpal ligament is preferred in severe cases of CTS and should be considered when conservative measures fail. A through knowl...

Previously presented evidence indicates that carpal tunnel syndrome is related to compression of the median nerve inside the carpal tunnel. Biomechanical arguments in which the extrinsic finger flexor tendons inside the carpal tunnel are characterized as a frictionless pulley-belt mechanism are presented to show quantitatively how wrist size, wrist position and hand position affect forces on th...

The transverse carpal ligament (TCL) forms the volar boundary of the carpal tunnel and may provide mechanical constraint to the median nerve, leading to carpal tunnel syndrome. Therefore, the mechanical properties of the TCL are essential to better understand the etiology of carpal tunnel syndrome. The purpose of this study was to investigate the in vivo TCL stiffness using acoustic radiation f...

Background :Carpal tunnel syndrome is a collection of symptoms due to compression the median nerve in carpal at wrist, one risk factors for occurrence syndrome, namely repetitive motion and working period. The purpose this study was determine relationship between tenure with incidence tailors. 
 Method :This type research an analytic cross sectional approach conducted on tailors Belian Vil...

Compression of the median nerve after Colles’s fracture has been well documented. The causes of compression that have been identified include haematoma within the carpal tunnel (Seddon 1975; Watson-Jones 1 976), hyperextension at the time of the injUry with direct nerve damage (Kirchman 1910; Sterling and Habermann 1973), and healing with excessive callus formation and malunion (Zachary 1945). ...

Median nerve (MN) compression is a recognized component of carpal tunnel syndrome (CTS). In order to document compressive changes in the MN during hand activity, the carpal tunnel was imaged with neuromuscular ultrasound (NMUS). Ten patients with CTS and five normal controls underwent NMUS of the MN at rest and during dynamic stress testing (DST). DST maneuvers involve sustained isometric flexi...

In 117 consecutive patients with carpal tunnel syndrome and 11 patients with a compression syndrome of the median nerve at elbow, motor and sensory conduction along the median and ulnar nerves and quantitative electromyography were compared with findings in 190 normal controls of the same age. In 25% of patients with carpal tunnel syndrome in whom motor conduction and EMG were normal, the lesio...
