A Morphometric Study of Iliac Crest of Hip Bone to Determine the Favourable Site for Harvesting Bone Graft

Objectives: To assess and compare the Computed Tomographic images of the hip bone aong various ages and gender to determine the favourable site for bone graft harvesting. Materials and methods: A total of 52 patients admitted in Gadag Institute of Medical Sciences who had done CT - Hip for various pathological conditions were assessed and width of Iliac crest was assessed in the respective CT - Scans at 5cm, 6cm, 8cm, 10cm on both left side and right side and this data was compiled together to get the maximum width ideal for bone graft and its compared across the various age groups and genders. Results: The mean width of the iliac crest for age less than 40 include at 5cm is 16.34mm, at 6cm is 15.20mm, at 8cm is 12.39mm, at 10cm is 10.91mm and for age more than 40 years include at 5cm is 16.16mm, at 6cm is 15.09, at 8cm 12.04 and at 10cm is 10.80mm on right side and for the age less than 40 include at 5cm is 16.26mm, at 6cm is 15.20mm, at 8cm is 12.40mm, at 10cm is 10.88mm and for age more than 40 years include at 5cm is 16.09mm, at 6cm is 15.08, at 8cm 12.05 and at 10cm is 10.79mm on right side. Conclusion: The maximum amount of cancellous bone required for bone graft in iliac crest is situated in the widest part of iliac crest which is around 5cm to 8cm from the tip of Anterior superior iliac spine. There was statistical significance in terms of gender or age for width of the iliac crest.
