Morphometric study of acetabulum in adult dry human pelvic bone

Abstract

Background: The knowledge of normal anatomical features and morphometry of the acetabulum is vital to understand the mechanics of hip joint. Present study was aimed for morphometric study of acetabulum in adult dry human pelvic bone. Material and Methods: Present study was prospective, observational study, conducted in hip bones which were dry, complete and showing normal anatomical features. Results: In present study, 100 Indian adult dry hip bones of known sex (50 male and 50 female) (50 right & 50 left) were studied. In male hip bones, mean acetabular Diameter was 5.13 ± 0.4 mm, mean acetabular depth was 2.82 ± 0.3 mm, mean notch width 2.17 ± 0.9 mm & mean acetabular capacity was 30.83 ± 4.6 mm. while in female, mean acetabular diameter was 4.34 ± 0.3 mm, mean acetabular depth was 2.59 ± 0.5 mm, mean notch width 1.61 ± 0.8 mm & mean acetabular capacity was 22.12 ± 4.2 mm. Difference between all parameters was statistically significant. In right hip bones, mean acetabular Diameter was 4.67 ± 0.4 mm, mean acetabular depth was 2.72 ± 0.3 mm, mean notch width 1.9 ± 0.5 mm & mean acetabular capacity was 27.74 ± 6.2 mm. while in left hip bone, mean acetabular diameter was 4.71 ± 0.4 mm, mean acetabular depth was 2.63 ± 0.3 mm, mean notch width 1.89 ± 0.4 mm & mean acetabular capacity was 26.86 ± 6.4 mm. Difference between all parameters was statistically not significant. Conclusion: The morphometric assessment of the acetabulum has a myriad of utilities for Anatomists, anthropologists, experts in forensic medicine and Orthopaedic surgeons for better alignment of acetabular cup placement during total hip Arthroplasty.
