A four trunked brachial plexus and a post fixed brachial plexus: a conjunction or a co-incidence? Report of three cases.

The anatomical variations of the brachial plexus in humans have clinical significance for surgeons, radiologists, and anatomists. In a study of 60 brachial plexuses, four trunked brachial plexuses were encountered in three limbs (two female and one male), all of them being post fixed and on left side of cadavers. The third trunk in all these limbs gave rise to two anterior divisions (upper and lower) and one posterior division.

The role of the anterior border of the hip bone in sexual dimorphism: a morphometric study in the North Indian population.

Understanding sexual dimorphism is very important in studies of human evolution and skeletal biology. The ability to determine sex from unknown skeletal remains is vital and methods to do this on the various bones of the human skeleton have been researched extensively especially in the studies related to forensic anthropology. The distinctive morphology and clear sexual dimorphism of the hip bone makes it an ideal bone for sex determination.

Determination of age from pubic symphysis: an autopsy study.

The present study was conducted on three hundred and thirty-six cases brought for autopsy to the Department of Forensic Medicine, Government Medical College, Amritsar, Punjab, India, during the period 2000-2002. Pubic bones of either sex were analysed according to Todd's method (1920; 1921a,b,c) as modified by McKern and Stewart (1957) to assess and compare the known age of the corpses. Cases belonged to both sexes, i.
