The effect of wrist position on the relative motion of tendon, nerve, and subsynovial connective tissue within the carpal tunnel in a human cadaver model

Abstract: The purpose of this study was to measure the effect of wrist position on the relative motion of the middle finger flexor digitorum superficialis (FDS) tendon, subsynovial connective tissue (SSCT), median nerve, and flexor retinaculum during simulated active finger motion. The relative motion of each tissue was measured by fluoroscopy in 10 human cadavers. Measurements were obtained for wrist positions of neutral (0 degree extension), 30 and 60 degrees of flexion, and 30 and 60 degrees of extension. The shear s… Show more

“…In addition, the tendons and median nerve together with the TCL form a pulley system (Brooks et al, 2003;Fuss and Wagner, 1996;Stecco et al, 2010). During finger and hand movements the median nerve and tendons move in longitudinal, transverse, and volar/dorsal directions (Lopes et al, 2011;Ugbolue et al, 2005;Yoshii et al, 2008). The median nerve becomes compressed as the carpal tunnel contents move within the carpal tunnel (Armstrong and Chaffin, 1979;Ugbolue et al, 2005).…”

“…Additionally, repetitive finger movements could result in a higher shear strain between the median nerve and the sub synovial connective tissue (Kursa et al, 2006;Yoshii et al, 2008). However, the association between computer work and CTS remains inconclusive, and the pathophysiological relationship between keyboard typing activity and CTS remains questionable.…”
