OK TO PLACE ACETABULAR CUP OUTSIDE “SAFE ZONE?”

OK_HipReplacement_WEBIn a retrospective study, Cleveland Clinic researchers set out to test the association between cup positioning and patient-reported functional and general health outcomes, as well as dislocation rate. Going in, the team hypothesized that cup positioning with reference to the native acetabular rim, rather than the reported safe zone, would affect dislocation risk and patient-reported outcomes. All participants received CT imaging when undergoing primary, unilateral total hip arthroplasty (THA) at a single academic center by six surgeons from March 2011-January 2015.

Carlos A. Higuera Rueda, M.D. is an orthopedic surgeon with Cleveland Clinic, Ohio, who co-authored the study. Asked how certain cup positioning might affect patient-reported functional and general health outcomes, he toldOTW, The positioning of the components, both acetabular and femoral, would dictate the hip range of motion free of impingement and potentially dictate the mechanics that rule the muscle function around the hip girdle. When the range of motion and the mechanics of the hip are affected, the gait and activities of daily living will be affected. The spine and other joint like the knee and ankle will be affected as well.”
