Incidence and Morphometric Dimensions of Psoas Minor Muscle in South Indian Population - A Cadaveric Study

Abstract

The present study was conducted in thirty two cadavers from the Department of Anatomy, Government Theni Medical College, Theni, Tamil Nadu, India. The psoas minor was found in two of the thirty two cadavers with an incidence of 6.25% in the present study. Apart from that, the muscle belly was longer than the tendinous part in contrast to other authors where the muscle belly was shorter than the tendon. In both the cadavers, the muscles derived its innervation from the ventral rami of first lumbar nerve on both sides. The study highlights the presence of psoas minor in South Indian population.
