Tips and Pearls

•Place the anterior portal where it will be most utilitarian for access and instrumentation within the central compartment, independent of anchor placement. •Use the Osteoraptor percutaneous anchor delivery system with an entry site sufficiently distal to minimize the risk of perforating the articular surface of the acetabulum. •Bisecting the difference between the anterior and anterolateral portals provides optimal access for anchor placement along the rim from below the 3-o'clock position anteriorly (on a right hip) to beyond the 12-o'clock position laterally. •Always observe the articular surface of the acetabulum while drilling. Any rippling of the cartilage indicates that the drill is too close and must be repositioned.
