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.
