The Proximal Femur in Egyptian (Morphometric and Radiological Study)

Zaki M, Shona S, Sayed W and Ghada A

Introduction: Knowledge about the different diameters of the head and neck of femur is essential in orthopedic surgery for prosthesis and nail application. The aim of this study was to evaluate the average FNA in the young Egyptians and the effect of age on it. Also, matching sex and side differences of the angle were done by using CT. In addition, the different growth parameters of the proximal femur were measured by using plain X-ray. Side, sex differences and correlation analysis between these parameters were also done.

Material and methods: Two hundred cases subjected to the plain X-ray from both sexes (110 males and 90 females) with age above 25 years old were used in the present study. The following measurements were taken the vertical diameter of neck (VDN), vertical diameter of head (VDH), transverse diameter of neck (TDN) and transverse diameter of head (TDH). Computerized tomography (CT) pelvis for the FNA was done in fifty cases. The study was limited to children aged from 6-11years. The children were of both sexes.

Results: In the present work, there was a significant difference of the VDH in the female cases regarding side. It was 6% and 8% lower in females compared to that of males on the left and right sides respectively. Also, there was a significant difference of the TDH in both sexes regarding side in the present study. The TDH was 5% lower in females as compared to that of males on the both left and right sides.

Conclusion: The mean values of the main measurements of the proximal femur of Egyptians differed from the values found in other populations. There was a significant difference between the males and females. Strong correlation between the different diameters on both sides was found.
