Abstract

Objective The aim of this article was to compare the force required to maintain the acetabular ventroversion after double pelvic osteotomy (DPO) and modified triple pelvic osteotomy (2.5PO).

Methods Unilateral DPO (group A) and unilateral modified DPO (group B = 2.5PO) were performed on cadaveric canine pelves (n = 10/group). The twisting moment required to maintain fragment position for DPO and 2.5DPO was compared.

Results Mean twisting moment for the DPO group [5.92 N/m ± 2.59 (range, 2.61–12.17 N/m)] and the 2.5PO group [2.11 N/m ± 0.93 (range, 0.63 -3.85 N/m)] was significantly different (p < 0.01).

Conclusion Dorsal cortex osteotomy of the ischium decreases the acetabular segment rotation force. Decreased force may facilitate acetabular rotation during DPO procedure.
