An
important consideration in the evaluation of the biomechanics of the tendons
and median nerve in the carpal tunnel is the normal range of variation in
their conformation and relative arrangement within the tunnel under otherwise
equivalent external conditions. The purpose of this study was to investigate
the range of median nerve deformation and position within the tunnel over a
series of imaging evaluations and following a set of specific pre-scan
activities. The results demonstrate
the complex motion and deformation of the median nerve in both neutral and
flexed wrist positions.
