Z-shaped capsular incision
Starting from the trochanteric physis at the anterior edge of the trochanteric osteotomy, a longitudinal incision is made towards the acetabulum (1).
Care must be taken not to cut into the labrum.
The second cut runs along the distal anterior insertion of the capsule around the calcar (2).
The third cut runs parallel to the edge of the acetabulum in a posterior direction (3).
