Anthropometric analysis of the hip joint in South Indian population using computed tomography

Abstract

Background:Proximal femur has a significant functional modification on erect bipedal posture. Various proximal femoral parameters were analyzed in Western literature. This information was utilized in prosthetic designing. Implants designed for Western people are used in Indian patients undergoing hip surgeries such as internal fixation and replacement arthroplasty.Materials and Methods:The study was done among 200 individuals (400 hips) with a normal hip joint after ethical committee clearance. Computed tomography scanning of proximal femur was done. Neck-shaft angle (NSA), neck width (NW), head diameter (HD), acetabular angle (AA) of sharp, horizontal offset (HO), vertical offset (VO), medullary canal diameter at the level of lesser trochanter (MDLT), and acetabular version (AV) were measured. These parameters were tabulated and compared with various populations and statistically analyzed.Results:The mean values were NSA 135°, NW 27 mm, femoral HD (HD) 42.5 mm, AA of sharp 35.5°, HO 37 mm, VO 46 mm, MDLT20 mm, and AV 18.64°. The values differ when compared with Western population. This study results differed when compared with other Indian studies done in Northern and Northeast Indian population. Significant differences noted in the parameters between sexes and between the sides of the hip joint.Conclusion:This study indicates that there are significant differences in anthropometric parameters of proximal femur among the South Indian population compared with Western population. Even within the Indian population, the anthropometric parameters vary region to region.

Morphology of Proximal Femur in South-West Coast of India

“…We observed a higher neck shaft angle in both groups, which were in contrast to that noted by Siwach et al 13 . Our findings, however, were comparable to those reported by Sengodan et al 17 , Deshmukh et al 18 and Saikia et al 19 wherein they reported higher neck shaft angles for the south, west and north-eastern Indian population, respectively. Anderson et al 20 studied inter-populational variation in human femoral neck shaft angles across 30 modern, historic and prehistoric human population samples and concluded that urban population have a higher neck shaft angle as compared to the non-mechanised rural population.…”

Radiographic analysis of the proximal femoral anatomy in the Croatian population

“…Multiple studies analyzed the proximal femoral morphology using different specimens and methods of measuring [ 10 , 11 ]. We decided to analyze conventional radiographies since they are used as a standard in pre-operative planning for total hip arthroplasty.…”

Estudio Anatomo-Tomográfico De La Versión Acetabular

“…Detallar estas variantes en una población local asintomática, fundamenta la comprensión de los parámetros normales acetabulares y distingue patologías de variables anatómicas normales (Vandenbussche et al, 2008). Aunque este rango de normalidad pueda diferir según sexo y raza (Sengodan et al, 2017). El presente estudio intenta observar estos parámetros, en nuestra población.…”
