Fig. 5From: Computer-assisted anteverting eccentric rotational acetabular osteotomy for recurrent posterior dislocation associated with acetabular retroversion: a case reporta The piriformis, obturator internus, and gemellus muscles were not torn. b, c The muscles were tagged and divided. The posterior capsule was torn at the lower ischial femoral ligament. d The planning angle and direction of the osteotomized fragment, both of which were calculated using the ZedHIP® software, were implemented intraoperatively using the CT-based Stryker Navigation SystemBack to article page
