“…The proximal femoral parameters are very important structural and functional specialization for mans erect posture 5 There are regional differences in the stature of human beings so prosthesis should be designed according to specific population 4 . It is vital to match the dimensions of the implant closely with those of the femur, as some of the complications resulting from mismatch could be aseptic loosening, improper load distribution and discomfort 11 .…”

“…Determination of the geometrical measurement of proximal end of femur was the main target 6 . The neck shaft angle (NSA) was measured by Goniometer (Fig 2) for which the axis of the neck was determined by a line dividing the anterior surface of the neck into two equal halves and the axis of the shaft was determined by the line dividing the anterior surface of the shaft in two equal halves 5 . Femoral head diameter (FHD) was measured by vernier calliper (Fig 2), and it was taken as mean of vertical diameter (distance between two extreme points along craniocaudal plane) and transverse diameter (distance between two extreme points along transverse plane).…”

“…It has a proximal rounded, articular head projecting medially from its short neck, which, in turn, is a medial extension of the proximal shaft 1,2,3 . The neck of the femur in humans is an important functional modification after man attained erect bipedal posture 5 . The femoral neck is approximately 5 cm long, narrowest in its mid part and widest laterally, and connects the head to the shaft at an average angle of 135° (125 0 by Snells clinical anatomy 2 ) (angle of inclination; neck-shaft angle): this facilitates movement at the hip joint, enabling the limb to swing clear of the pelvis.…”

“…The study of morphological features of the proximal femur like Femoral head diameter (FHD), Horizontal offset (HO) and Neck shaft angle (NSA) are very essential component in preoperative planning prior to total hip arthroplasty because it is vital to match the dimension of the implant with those of the femur 6 . These implants are designed primarily for use in Western population, whose constitutional and biomechanical factors vary from those of Indian population 5 . Otherwise, inappropriate sized or incorrectly placed prosthesis might cause aseptic loosening and improper load distribution causing huge discomfort to the patient thus ultimately affecting long term success of the operation 6 .…”

Objectives Recently, more accurate description of the femoral geometry has become of interest to engineers and orthopedic surgeons. However, an appropriate database is lacking. Therefore, the aim of this study is to present morphological parameters and their correlations, which are relevant for medical issues such as impingement after total hip replacement, as well as for implant design and the etiology of hip fractures. Methods We investigated 12 well‐known morphological parameters of the femur in 169 healthy human subjects through evaluation of 3D‐reconstructed CT scans. Pearson's coefficients of correlations were calculated using a statistical t ‐test method for each pair of parameters. Results The mean, maximum, minimum, median, and standard deviation values are reported for all parameters. Histograms showing the distribution of each morphological parameter are also presented. It is shown that absolute and horizontal offsets, total femur length, and NCVD parameters are normally distributed, but NCDF and NCDS are not. Furthermore, an inter‐correlation matrix was reported to reveal statistical correlations between these parameters. The strongest positive correlation existed between absolute offset (OSA) and horizontal offset (OSH), while the least positive correlation was found between NCDF and total femur length (TFL), and also between NCDS and NCDF. Anteversion angle (ATA) and OSA showed the least negative correlation. However, the strongest negative correlation was found between neck‐shaft angle (NSA) and greater trochanter height (GTH), as well as between OSA and NCVD. Conclusions Comprehending patients’ native bone morphology, including the variations and correlations, is essential for orthopedic surgeons to undertake preoperative planning and surgery as well as to appropriately design medical devices. Thus, more population‐based detailed databases are necessary. We investigated an extensive set of proximal femoral morphology parameters using a statistically standardized method to expand the existing knowledge. The results of our study can be used for diverse medical and biomechanical purposes.
