National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Biomechanical Analysis of Personal CTS (Carpal Tunnel Syndrome) Attributes,

PB88247705

Publication Date	1978
Personal Author	Rolecki, J. M.
Page Count	79
Abstract	The importance of wrist size and the effect of high force loads on tendons were investigated in relation to carpal tunnel syndrome (CTS). The geometry of the curvature of the finger flexor tendons as they pass over the trochlea of the wrist was estimated using a relationship between the change in joint angle of the wrist and displacement of the flexor tendon to determine the radius of curvature of the tendon. Human cadaver limbs were dissected and direct measurement were made of the spatial location of the tendon. The radius of curvature of the tendon in the vicinity of the trochlea was determined by fitting polynomials to the data. The radius of curvature of the finger flexor tendons was found to range from about 0.9 to 4.0 centimeters. No predisposition of the wrist to the development of CTS was evidenced by the five bone dimensions which indicate wrist size and hand length. Variations in wrist structure were not found to be an etiological factor in the occurrence of CTS.
