“…Coxa vara is a hip deformity, where the angle between the femoral head and the anatomical axis is smaller than 120° (1-5). On the other hand, an angle greater than 135° is defined as coxa valga (1,2,5). Both deformities result in aberrant leg development, weakness of the hip joint and surrounding musculature and could originate in very early development, as a consequence of injury or surgical intervention, as well as diseases such as idiopathic or postseptic arthritis (6), metabolic bone diseases such as Paget's disease, osteomyelitis, neuromuscular diseases (e.g.…”

Introduction: The femur is a long bone (ossa longa) that forms the hip and knee joints, supporting the weight of almost the entire body. This study is based on analyzing certain angles on the proximal femur that represent anthropometrically and surgically significant parameters, with clinical significance in diseases such as metabolic and degenerative bone disorders, arthritis, various hip trauma and disease. Aim: Determining the significance of certain morphometric parameters of the proximal femur and exploration of their impact on the hip joint. Material and methods: This cross-sectional study encompasses measuring four parameters: shaft length, the collodiaphyseal angle (CDA), the medial proximal femoral angle (MPFA) and the lateral proximal femoral angle (LPFA), on adult femora belonging to the archive of the Institute of anatomy "Niko Miljanić" of the Univerisity of Belgrade, Faculty of Medicine. A digital goniometer precise to two decimal places was used for all measurements. Results: Forty-seven femora were examined, 25 of which were left and 22 right femora of unknown gender and age, since none of the examined parameters could be used in procuring such information. The average femoral shaft length was 39.9 ± 2.7 cm, the shortest 34.8 cm and the longest 45.7 cm. The Collodiaphyseal angle (CDA) was 127.64 ± 4.25° on average, with the minimum being 119.1° and the maximum 137.7°. Average LPFA was 87.21 ± 3.07°, the lowest 81.6 and the highest 93.0°. Finally, MPFA was 86.9 ± 3.73° on average, with the smallest being 78.7° and the largest 94.5°. The Medial proximal femoral angle of right femora was significantly lower than the MPFA of left femora (p = 0,016). Conclusion: Eleven samples had a CDA below normal (< 124°), with three being defined as coxa vara (CDA < 120°). One had a CDA above normal (> 135°), being defined as coxa valga. Outside of reference values, LPFA was determined on 11 samples, being below normal (<85°) in all of them, whilst MPFA had 13 with only one of them being below normal (< 80°).

Introduction: The collodiaphyseal angle (CDA) is an angle formed between the femoral neck and femoral shaft axes. It is a vital determinant of femoral neck fracture as narrower angle is often used as a predictor of stress fracture. It is also important in orthopedic treatment planning, especially hip replacement surgery. Aim: This study was carried out to evaluate the CDA values among the Bini tribe and elucidate its significance. Methodology: This study employed 200 anterior-posterior pelvic radiographs of the Bini tribe (100 males and 100 females) aged between 25 and 55 years obtained from selected radiological diagnostic centers in Benin City, Nigeria, after obtaining the Institutional Ethical Approval. They were used to evaluate the right and left CDA as an angle formed by intersection of the femoral neck and shaft axes and measured using the goniometer. Data were statistically analyzed using IBM-SPSS (version 20) with the mean, standard deviation, and range evaluated, and side and gender comparisons were done using t-test, and P < 0.05 was set as statistically significant level. Results: The average CDA was 135.56° ± 5.75° and 131.67° ± 6.15° in males and females, respectively. This angle showed significant gender differences bilaterally (P < 0.05). However, the bilateral differences in the CDA were not statistically significant among either male or female Binis (P > 0.05). Conclusion: The CDA can be employed as a morphometric indicator of sexual differences and for other clinical applications.
