Introduction: The femur is the largest and strongest bone of the body that forms the skeleton of the thigh. The morphometry of proximal end of femur are variable between different individuals with different Nationality. The aims and objective of the study is to find out the morphometric measurements- Femur Length, Femur head diameter, Femur neck shaft angle, and Femur neck length, breadth and thickness. Methods: A total of 75 femurs of both sex were collected from the Department of Anatomy, MCOMS, Pokhara. The parameters on proximal femur were measured manually with the help of measuring scale, thread, protector and vernier calliper. The collected data were analyzed with Microsoft Excel 2007 software and represented graphically. Results: In the present study, the average femoral length for entire femur was 42±2.81 cm, femoral head diameter was13.05±0.9 cm, femoral neck length was 4.12±0.32 cm, femoral neck breadth was 2.94±0.30 cm, and femoral neck thickness was 2.36±0.42 cm. The femur neck shaft angle of left femur was significantly higher than that of right femur (P-value 0.03). There was no difference between other dimensions of proximal end of right and left femur. Conclusion: The results of the present study show that the dimensions of proximal femur in Nepalese Population are different as compared to other countries population. The knowledge of different dimensions of proximal femur will be important in anthropological and medico-legal practice for sex determination and as well as to radiologists and orthopaedic surgeons for diagnosis and planning of treatment.

Abstract Purpose The goal of total hip endoprosthesis is to achieve painless and functional hip for long term. Accurate reconstruction of hip anatomy largely depends on the implant design. In order to select an implant in correspondence with the native hip, the proximal femoral morphology has been in focus of many studies in the past years. The purpose of this study is to analyze proximal femoral geometry in the Croatian population by radiographic evaluation. Methods We conducted a retrospective study analyzing conventional radiographies of the hip, obtained within the last four years from the database of Clinic for Orthopaedic Surgery Lovran. The number of studied patients was 300,168 women and 132 men. The proximal femoral geometric parameters assessed were as follows: femoral head diameter, femoral neck length, neck-shaft angle, angle of femoral neck anteversion, and lateral femoral offset. The results obtained were compared between genders and with results of other studies. Results Proximal femoral anatomy differed in femoral head diameter and lateral femoral offset between males and females in our group of patients, while femoral neck length, femoral neck shaft angle, and femoral neck anteversion have shown similar values in both genders. Our study also showed specificity of the Croatian population in almost all parameters of proximal femoral anatomy, in comparison with other ethnic groups. Conclusion Our results support the observation on high diversity in the morphology of the proximal femur and the specificity of the proximal femoral anatomy of the Croatian population.

BACKGROUND The peculiar waddling gait of a female attracts most of the anatomists to measure and compare the neck-shaft angle (NSA) of the femora. The femoral neck shaft angle is greater in women due to greater pelvic breadth and shorter femur. Neck-shaft angle was measured by the angle that the neck makes with the shaft of the femur and it is measured on the ventral surface of femur taking the long axis of femoral neck with the long axis of the proximal end of the femur. It gives information about the race it belongs to and normally measures 120° to 140°. The intention of this study was to establish the femoral neck shaft angle variations in adult male and female for medico-legal and anthropometric studies. METHODS This cross-sectional study was conducted on 84 adult human femora of unknown sex in the anatomy department, Sriram Chandra Bhanja (SCB) Medical College, Cuttack, Odisha, from May 2018 to April 2019. We included all the femora which were free of damage or deformity and fully ossified indicating adult bone. Femora with any pathological changes i.e., cortical bone deterioration, extreme osteophyte activity, osteoarthritis and fracture etc. were excluded from the study. The NSA was measured by protractor and goniometer. RESULTS In the present study the NSA range for the right femur of male was 108° - 135° and for the right femur of females 117° - 135°. The left male femur was 118° - 135° and the left female femur was 120° - 135°. The mean neck shaft angle of male femora was 125.9° and the female femora was 125.7°. These measurements show that the values were more in males than the females. The value of the present study was statistically significant between male and female i.e., P < 0.0001. CONCLUSIONS These measurements are important in the medico-legal cases, reconstructive orthopaedic surgeries, hip replacement surgeries and also while constructing suitable prosthesis. This will also be helpful in the detection of sex by anatomists and forensic experts. KEY WORDS Neck Shaft Angle, Medico-Legal, Anthropometry and Goniometer

Abstract Background When performing femoral reconstruction in patients with Crowe type IV developmental dysplasia of the hip (DDH), anatomical deformity presents many technical challenges to orthopedic surgeons. The false acetabulum is suggested to influence load transmission and femoral development. The aim of this study was to describe the morphological features of dysplastic femurs in Crowe type IV DDH and further evaluate the potential effect of the false acetabulum on morphological features and medullary canal of Crowe type IV femurs. Methods We analyzed preoperative computed tomography scans from 45 patients with 51 hips (25 hips without false acetabulum in the IVa group and 26 hips with false acetabulum in the IVb group) who were diagnosed with Crowe type IV DDH and 30 normal hips in our hospital between January 2009 and January 2019. Three-dimensional reconstruction was performed using Mimics software, and the coronal femoral plane was determined to evaluate the following parameters: dislocation height, dislocation ratio, height of the femoral head (FH), height of the greater trochanter (GT), GT–FH height discrepancy, height of the isthmus, neck-shaft angle, femoral offset and anteversion of the femoral neck. The mediolateral (ML) width, anterolateral (AP) width and diameter of medullary canal of the proximal femur were measured on the axial sections. Further, canal flare index (CFI), metaphyseal-CFI and diaphyseal-CFI were also calculated. Results Compared with the normal femurs, the Crowe type IV DDH femurs had a higher femoral head, larger GT–FH height discrepancy, larger femoral neck anteversion, higher isthmus position and smaller femoral offset. Dislocation height and dislocation rate were significantly larger in the IVa DDH group (65.34 ± 9.83 mm vs. 52.24 ± 11.42 mm). Further, the IVb femurs had a significantly lower isthmus position, larger neck-shaft angle and smaller femoral neck anteversion than IVa femurs. The ML, AP canal widths and the diameter of medullary canal in both DDH groups were significantly smaller than the normal group. Dimensional parameters of IVa femurs were also narrower than IVb femurs in most sections, but with no difference at the level of isthmus. According to the CFIs, the variation of proximal medullary canal in IVb femurs was mainly located in the diaphyseal region, while that in IVa femurs was located in the whole proximal femur. Conclusions High dislocated femurs are associated with more anteverted femoral neck, smaller femoral offset and narrower medullary canal. Without stimulation of the false acetabulum, IVa DDH femurs were associated with higher dislocation and notably narrower medullary canal, whose variation of medullary canal was located in the whole proximal femur.

Objective: This study was conducted to investigate the risk of hip fracture using proximal femoral morphometry in fractured and nonfractured postmenopausal women.Methods: We conducted an observational cross-sectional study with 138 postmenopausal women (49 fractured and 89 nonfractured). The hip axis length (HAL), femoral neck axis length (FNAL), acetabular width (AW), femoral head width (FHW), femoral shaft width (FSW), and femoral neck shaft angle (FNSA) were measured in all cases by dual energy X-ray absorptiometry. We also studied the correlation between body mass index (BMI) with all the parameters in fractured and control groups.Results: The mean age, height, weight, and BMI were 61.24±3.23, 163.94±7.84 cm, 71.88±9.14 kg, and 26.72±2.78 kg/m², respectively, in fractured patients. In nonfractured patients the values were 59.73±5.32, 161.73±4.25 cm, 69.54±6.25 kg, and 26.74±2.23 kg/m² respectively. The mean HAL, FNAL, AW, FHW, FSW, and FNSA were 130.5±3.18 mm, 111.26±3.64 mm, 18.2±1.91 mm, 53.46±1.51 mm, 37.45±1.82 mm, and 132.76±3.15 degree incase group and 130.84±4.74 mm, 112.48±4.08 mm, 17.57±2.32 mm, 53.4±1.86 mm, 35.29±1.82 mm, and 128.76±3.6° in control group, respectively.Conclusion: The femoral parameters such as HAL, FNAL, AW, and FHW do not indicate any correlation between fractured and control groups, whereas FSW and FNSA were significantly higher in case group. The FNSA was having significant negative correlation with BMI in fractured group while that was having a significant positive correlation in the nonfractured group. This observation will be helpful in exploration of its clinical significance in proximal femoral fracture.Keywords: Proximal femur, Morphometry, Postmenopausal, Fracture.
