MRI-Apparent Localized Deformation of the Median Nerve Within the Carpal Tunnel During Functional Hand Loading

The median nerve in the carpal tunnel.

A study of the variations of the course and branching pattern of the median nerve within the carpal tunnel were carried out on 60 wrists from 30 fresh cadavers autopsied in the Department of Forensic Medicine of Jagiellonian University Medical College. The results were compared with the literature. The study confirmed that the extraligamentous type of motor branch variation is most common. The ...

Ultrasound imaging of the carpal tunnel during median nerve compression

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...

Median nerve compression in the carpal tunnel.

portant that the physiotherapist should supervise the movements and make sure that the metacarpal is again moved through a full active range at the new joint. This treatment is continued until the patient can return to light work, which is usually a matter of four to six weeks. Some patients complain of pain for longer than this, but others are surprisingly pain free; one started milking cows w...

Investigation of local deformation of the median nerve in magnetic resonance images of the carpal tunnel

Altered median nerve deformation and transverse displacement during wrist movement in patients with carpal tunnel syndrome.

RATIONALE AND OBJECTIVES Carpal tunnel syndrome (CTS) is the most common peripheral nerve entrapment syndrome. Strong pinch or grip with wrist flexion has been considered a risk factor for CTS. Studying median nerve displacement during wrist movements may provide useful information about median nerve kinematic changes in patients with CTS. The purpose of this study was to evaluate the deformabi...
