The calcaneal angle in Nigerians. Relationship to sex, age, and side of the body.

The authors studied the calcaneal angle in Nigerians and found it to range from 28 degrees to 38 degrees with a mean of 32.83 degrees (SD 2.84 degrees). The calcaneal angle in Nigerians is not significantly related to sex, age, or side of the body (left or right). Proper alignment of the calcaneus is essential for the maintenance of the arches of the foot, for standing erect, and for walking and running. Thus the calcaneal angle must be borne in mind whenever reconstructive surgery is performed.
