The aim of this study was to determine the location of the motor
points and the intramuscular branches of the wrist flexors in relation to bony
landmarks. DESIGN: Sixteen limbs from eight adult cadavers were anatomically
dissected. The motor branch points of the flexor carpi radialis and flexor carpi
ulnaris muscles and the proximal limit points and the distal limit points in
relation to a reference line connecting the medial epicondyle and the pisiform
bone or one connecting the medial epicondyle and the base of the second
metarcarpal bone were identified. RESULTS: For the flexor carpi radialis muscles,
the motor branch points were located at a distance of 27% +/- 6% of the reference
line, whereas the proximal limit points and the distal limit points were located
at a distance of 21% +/- 5% and 37% +/- 8% of the reference line. For the flexor
carpi ulnaris muscles, the corresponding data were 32% +/- 8%, 23% +/- 6%, and
43% +/- 9%. CONCLUSIONS: The results may assist in enhancing accuracy when
localizing points for neuromuscular blockade of the wrist flexors. The optimal
area for flexor carpi radialis muscle injection is at a quarter point and that
for flexor carpi ulnaris muscle injection is at one-third point along each
reference line from the medial epicondyle.
