“…On the opposite side, the VDH and TDH in adult male and female Caucasians and Mongoloid [14], South Indians [15] and Brazilians [16] were lower than these of the present study. he South Indian populations are vegetarians, so they lack the protein in their food habit and this may be the reason for their low dimensions [8].…”

Introduction: Knowledge about the different diameters of the head and neck of femur is essential in orthopedic surgery for prosthesis and nail application. The aim of this study was to evaluate the average FNA in the young Egyptians and the effect of age on it. Also, matching sex and side differences of the angle were done by using CT. In addition, the different growth parameters of the proximal femur were measured by using plain X-ray. Side, sex differences and correlation analysis between these parameters were also done.

“…he TDN was 7% and 8% lower in females as compared to theses of males on the right and let sides respectively. In support of the current work, many authors reported similar side diferences of theses parameters among populations from India and Brazil [1,15,16]. he mean of all these studies, were lower than theses of the present study.…”

Novel potential marker for native anteversion of the proximal femur

et al. 2016

Identifying native femoral version from proximal femoral landmarks would be of benefit both for preoperative assessment as well as intraoperatively. To identify potential markers for femoral anteversion, an empirical framework was developed for orientation-independent analysis of the proximal femur from pelvic CT to allow for segmentation of the proximal femur into five constituent regions: Femoral head, femoral neck, greater trochanter, lesser trochanter and femoral shaft. The framework is based on the identification of differences in the radius of curvature at anatomic zones of transition between regions of the proximal femur, followed by non-linear geometric shape fitting. The framework is applied to 86 proximal femurs segmented from pelvic CTs, with at least 2 cm of proximal femur remaining below the lesser trochanter, obtained for non-musculoskeletal pathology to investigate potential proximal femoral markers for native femoral version. The analysis of the proximal femur suggests a fixed relationship between the maximal femoral canal diameter 1 cm proximal to the base of the lesser trochanter from the center of the greater trochanter and the femoral neck axis of 4.13° +/- 4.99°. Further full-length femoral studies are needed to confirm the relationship of the maximal canal diameter as a proxy for native femoral anteversion. Published by Wiley Periodicals, Inc.

“…1 ). For evaluating femoral neck length, the articulo-trochanteric distance (ATD) [ 23 ] and femoral neck length ratio [ 24 ] was measured and calculated, respectively. For evaluating acetabular morphology and subluxation, Sharp angle [ 25 ], acetabular roof angle [ 26 ], lateral center-edge angle (LCEA) [ 27 ], medial joint space (MJS) width ratio [ 28 ], and center-head distance discrepancy (CHDD) [ 29 ] were measured.…”

BackgroundThe purpose of this study was to evaluate the radiologic outcome of percutaneous medial hemi-epiphysiodesis using a transphyseal screw for the management of caput valgum associated with developmental dysplasia of the hip (DDH).MethodsEighteen hips (18 patients) having caput valgum treated with screw hemi-epiphysiodesis were followed for more than 2 years, and were included in this study. The mean age at the time of the index operation was 8.3 years (range, 4.3 to 10.7 years) and age at the latest follow-up was 12.2 years (range, 9.4 to 16.4 years). The screw in 5 hips was changed into a longer one at postoperative 21.8 months (range, 14 to 29 months) because the proximal femur outgrew the screw. The screws in 11 hips were removed at the mean age of 10.9 years (range, 8.0 to 14.5 years). We retrospectively analyzed the change in various radiologic parameters over time.ResultsThe mean Hilgenreiner-epiphyseal angle (HEA) of the operated side was 5.1 ± 11.3° preoperatively, and increased to 20.6 ± 11.3° at the latest follow-up (p = 0.001). The mean difference of the HEA between the operated and contralateral sides was 16.9 ± 15.1° preoperatively, which decreased to 2.4 ± 12.4° at the latest follow-up (p = 0.008). The mean articulo-trochanteric distance of the operated side, which was 3.2 ± 5.5 mm longer than that of the contralateral side preoperatively, became 5.6 ± 9.1 mm shorter at the latest follow-up (p = 0.001). The ratio of femoral neck length of the operated side to that of the contralateral side decreased over the follow-up period. Acetabular shape as measured by the Sharp angle and acetabular roof angle and femoral head coverage as measured by lateral center-edge angle did not change significantly by the index operation. The ratio of medial joint space width of the operated side to that of the contralateral side did not change significantly.ConclusionsScrew medial hemi-epiphysiodesis can effectively correct caput valgum associated with DDH. However, this technique remains coxa brevis and does not seem to significantly affect acetabular morphology or reduce subluxation.
