Clinical, Neurophysiological and Sonographic Characteristics of The Carpal Tunnel Syndrome Isolated and Against the Background of Polyneuropathy

Abstract

In article the clinical, neurophysiological and sonographic characteristics of 36 patients with existence of the clinical signs of a carpal tunnel syndrome a divided into two groups is given. 18 patients from a carpal tunnel syndrome with polyneuropathy of various etiology with average age of 55.1±5.79 years and the second group of 18 patients average age of 52.7±11.34 years with the isolated carpal tunnel syndrome entered into the first group. To patients clinical trial, a nerve conduction studies and sonography (66 wrists - 34 in 1 group and 32 in the 2nd group) joints and adjacent soft tissues and peripheral nerves for determination of the area of a median nerve was conducted. Results of the carried-out statistical, including correlation analysis of clinical and neurophysiological and sonographic indicators are described that allowed to draw conclusions on features of a carpal tunnel syndrome at development it at patients with polyneuropathy in the form of a tendency to formation of a bilateral carpal tunnel syndrome with swelling of a trunk of a median nerve, as a rule without the accompanying damages of joints and other adjacent soft tissues. And also more expressed defeat of terminal departments of axons of motor fibers, development of an axonal degeneration as motor and sensor fibers, and demyelination of sensor fibers with accurate correlation dependence on the area of a median nerve.
