Le. Bickerton et al., FLEXOR DIGITORUM SUPERFICIALIS - LOCATIONS OF INDIVIDUAL MUSCLE BELLIES FOR BOTULINUM TOXIN INJECTIONS, Muscle & nerve, 20(8), 1997, pp. 1041-1043
Twenty-two Flexor Digitorum Superficialis (FDS) muscles from 18 cadave
rs were dissected to find the ''Optimal Injection Site'' (OIS) for bot
ulinum toxin injections to individual bellies of FDS. Coordinates are
given as a percentage of the distance along a landmarking line from th
e medial epicondyle to the pisiform and in millimetres (mm) lateral to
it. The OIS were: FDS2: 72%, 14 mm; FDS3: 54%, 17 mm; FDS4: 49%, 7 mm
; FDS5: 76%, 6 mm. OIS measurements guide the electromyographer to loc
alize the targeted muscle belly. (C) 1997 John Wiley and Sons, Inc.
