Profound Morphometric Analysis of Acetabulum in South Indian Population (Acetabular Dimensions)

Abstract

Acetabular dimensions plays a challenging role in various arthroplasties and reconstructions. Morphometric study of acetabulum of dry hip bones is a necessity to make proper prosthesis and to ensure good quality of life. Materials & methods - In this 71 dry human hip bones of 35 right and 36 left collected in department of anatomy of Chettinad Hospital and Research Institute, to analyze & measure the diameter, acetabular notch, acetabular circumference, depth and volume of acetabulum. Results – The transverse diameter on right-49.33 ± 7.36 mm, left 48.57±6.79 mm, depth-right23.28±3.27 mm, left 22.50 ±3.18 mm, vertical diameter- right 48.05±4.40 mm, left 47.66±4.95 mm, acetabular notch- right 22.00±3.28 mm, left 20.56±2.61 mm, outer rim circumference -right 11.90±0.99 cm, left 12.43±0.87 cm, inner rim circumference- right 7.66±0.84 cm, left 8.06±0.72 cm, acetabular circumference-right 15.26±1.38 cm, left 14.60±1.35 cm, capacity- right 27.22±5.43 ml, left-27.22±5.77 ml. Conclusion - All the parameters were statistically analysed and the results suggest that the acetabular dimensions are mostly smaller in South Indian population and hip prosthesis should be made patient specific to increase the success rate of arthroplasties.
