Morphometric analysis of angle of inclination of human adult femur from north India: A radiological study
Dilip Sudele, Mridul Tripathi
Background: The femur is the longest & strongest bone in the body and has three parts; proximal, distal end and a long shaft. The neck shaft angle varies with age, stature & width of pelvis. Knowledge of neck shaft angle is an important to know the race to which they belong but also helps in the diagnosis, treatment and fellow-up of hip fracture, slipped upper femoral epiphysis, developmental dysplasia of the hip Objective: To determine the angle of inclination in human adult femur as per morphometric parameters and to find out any variation in the angle of inclination. Material and Methods: A total of 70 cases of Antero-posterior view of pelvic radiograph taken from the Department of Radiology, IIMS & R, Integral University, Lucknow, Dahod were enrolled for present study. After taking the X-ray film, marked the inclined line on X-ray film along the long axis of the neck of femur and long axis of shaft of femur. Then the angle between them was measured. Results: Out of 70 samples most of the cases were between 20-30 years (35.7%) Among that 37(52.9%) were males while 33(41.9%) were females. The mean right angle of inclination was 126.760±4.330 and left angle of inclination was 128.100±5.340. The right side of angle of inclination was higher in the age group of 20-30 years. The left side of angle of inclination was higher in the age group of 31-40 years. The right side and left side both of angle of inclination was higher in males than females. Conclusion: Anatomical study of femur bone serves helpful data to understand different aspect of clinical disease conditions, including common site of fracture, changes in osteoporosis, associated congenital anomalies as well as medico legal cases.
