Pelvic Osteotomies

‼️ What types of pelvis osteotomies do you know about?

• "There are 3 main kinds of osteotomies - reorientation, reshaping and salvage

‣

1. Reorientation aka re-directional = modify orientation w/o changing volume

• Suitable for DDH that requires anterior coverage

‣

Salter (open tri-radiate) - used in Paeds DDH, Perthes

• Osteotomy of anterior and posterior column with Hinge at pubic symphysis, providing anterolateral coverage

‣

Steel’s triple osteotomy (closed)

• Same concept as Salter but because pubic symphysis becomes less flexible (never closes but becomes stiff) - so add on pubic and ischial cuts.

‣

Ganz Bernese PeriAcetabular Osteotomy (PAO) (closed)- used in adult DDH

• 4 cuts - superacetabular, retroacetabular, pubic and Partial ischial
