Periacetabular Osteotomy: Groin Incision-Assisted Approach
Acetabular dysplasia is a common cause of osteoarthritis. The Bernese periacetabular osteotomy (PAO) as described by Ganz is a powerful tool that enables correction of inadequate femoral head coverage due to acetabular dysplasia. In addition to decreasing pressure forces on hip cartilage by increasing contact surface area, it can decrease joint reactive forces through medialization of the hip joint. Also, the osteotomy allows for correction of acetabular version. Since its inception in the mid-1980s, multiple modifications have been described. In this chapter, we will highlight a modification that utilizes a groin incision to perform the ischial and pubic cuts.
