Variation of Proximal Femoral Morphometry in Relation to Total Hip Replacement: A Study on Dry Femora
Objective: Objective: Considerable variations exist in geometry of proximal femur across populations, which play an important role in total hip replacement surgeries. However, a rigorous characterization of femoral geometry across different geographical localities in Pakistan has not been performed. We aimed to assess the variations of the proximal femoral geometry in dry human femur bones from two different regions of Pakistan.
Study type settings & duration: A descriptive study was carried out at Islamic International Medical College, Rawalpindi and at three different Medical Colleges in Peshawar from October 2018 to July 2019.
Methodology: After obtaining ethical approvals, complete, fully ossified bones without additional paint or visible pathology from Rawalpindi (N = 98) and Peshawar (N = 112) were included for measurements of neck shaft angle (NSA), vertical head diameter and femoral neck length. NSA was measured from sketches of bones by using goniometer placed parallel to the shaft axis, while regular scale was used for measuring vertical head diameter and neck length. Unpaired T test was performed to compare the variations of femoral geometry in a side- and region-specific manner from Rawalpindi and Peshawar regions of Pakistan.
Results: Means and SD values of NSA, vertical diameter of head and neck length of all bones were 125.85˚± 7.35, 42.17±4.25 mm and 54.2±6mm, respectively. Significant differences (p value <0.001) were observed for NSA, vertical diameter of head and neck length between bones from the two regions. The femoral geometry was similar between right and left side bones, except for NSA in .......
