Abstract

A study on the variations of the forearm and hand muscles was carried out at the Kasturba Medical College International Centre, Manipal, India. Eighty one limbs were included in the study. In 2 limbs (2.46%) the flexor digitorum superficialis muscle (FDS) had only three tendons; Accessory bellies of the FDS were found in 22 limbs (27.16%); The accessory belly of FDS was dividing into two tendons in 1 limb (1.23%) and in 2 limbs (2.46%), a high origin (in the carpal tunnel) of lumbricals was noted. The variations reported here may be of importance for the orthopedic surgeons, plastic surgeons and other medical disciplines.
