The biomechanics of pelvic osteotomy according to the Chiari method.

The authors analyze the biomechanical effectiveness of pelvic osteotomy according to the Chiari method. This type of operation reduces joint loading and increases the joint support surface. The authors examined 18 patients aged an average of 31 years. This series shows that the effectiveness of pelvic osteotomy according to the Chiari method is particularly observed in cases in which joint morphology is best preserved.
