Osteoporosis was assessed at the hip (Singh's index) and calcaneus (calcaneal
index) using conventional radiography in 80 patients (31 men, 49 women) with
fracture neck of femur. Forty four patients had intracapsular fracture neck of
femur (ICFN), and 36 extracapsular fracture neck of femur (ECFN). Fractures
occurred more with increasing age in both groups, with female preponderance in
the older age group. Osteoporosis was more severe as age advanced. Singh's index
decreased from 5.2 to 3 (ICFN), and from 4.1 to 2.65 (ECFN) with age. Calcaneal
index decreased from 4.4 to 2.9 (ICFN) and from 4.1 to 2.6 (ECFN) with age. In
summary degree of osteoporosis, assessed at the hip and calcaneus, increased
with increasing age. Other recent studies have shown that calcaneal bone density
is a valid method to predict future risk of hip fracture.
