Brief Summary:

Carpal tunnel syndrome (CTS) is a common condition that still lacks a reliable, objective screening test. Many anatomical aspects of the syndrome have been studied including the dimensions of the carpal tunnel and shape of the nerve within the tunnel. The investigators have observed varying amounts of muscle overlying the carpal tunnel in patients undergoing surgery for the condition. Assuming that this muscle may have a dynamic role in the development of the condition, the investigators attempted to quantify this muscle using ultrasound (US).

The purpose of this study was to devise a technique to evaluate the amount of muscle overlying the carpal tunnel.

The hypothesis is that patients with carpal tunnel syndrome will have significantly more muscle overlying the carpal tunnel than individuals without carpal tunnel syndrome.
