“…It was reported that the femoral neck-shaft angle and femoral anteversion did not have a significant relationship with the development of hip osteoarthritis. 19 Therefore, it is known that the variations in the proximal femur do not have a relationship with arthrosis of the hip joint and that such conditions only cause anatomical changes. Worlicek et al, conducted a study in 2016 and showed that femoral anteversion was not a suitable reference that can be used during surgery on patients who underwent total hip replacement.…”

Background: The anatomy of the proximal femur comprises important landmarks for many orthopedic surgical procedures. However, this area exhibits morphological differences depending on race, gender and age. Besides being the insertion area of the hip flexor muscles, the lesser trochanter is also used as an angular reference in many orthopedic surgical procedures. The aim of this study is to investigate the morphologic relationship of the lesser trochanter with the femoral neck and greater trochanter.Methods: Around 67 dry femur bones (32 left, 35 right) belonging to humans of unknown gender that belong to the Ankara University Medical Faculty, Department of Anatomy were used in this study. The morphologic relationship of the lesser trochanter (TRMI) with the femoral neck (FN) and greater trochanter (TRMJ) was studied and the results were provided in a table.Results: The measured mean lesser trochanter and greater trochanter tip distance was 67.5±4.9mm (60mm-75mm). The angle between the tip of the lesser trochanter and the center of the femoral neck was measured as 35.050±5.060 (290-420) degrees. The distance between the tip of the lesser trochanter and the center of the femoral neck was measured as 15±2.8mm (10mm-20mm).Conclusions: In addition to the angular relationship of the lesser trochanter with the femoral neck, its relationship in terms of distance with the greater trochanter and femoral neck are the anatomic relationships that are noteworthy for the lesser trochanter, which is used as a landmark during orthopedic surgical procedures.

“…Abnormal morphology, such as joint deformity, has been observed to affect the development of early osteoarthritis (e.g. in cases of high neck‐shaft angle [NSA]). Other morphological parameters, such as the femoral head diameter (FHD) and the anteversion angle (ATA), influence the range of motion (ROM) of the hip joint.…”

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.
