All implants demonstrated evidence of bony ingrowth and stable fixation with no cases of loosening, instability, deep infection, stress shielding, subsidence or osteolysis at last follow-up. Complications included two intra-operative fractures, three dislocations, one superficial infection, and one patient with thigh pain. No femoral stems were revised. Good to excellent clinical outcomes were achieved on Harris Hip Score (90% (n = 47\/52), Western Ontario and McMaster Universities Index (92% (n = 48\/52), and University of California Los Angeles activity score (96% (n=50\/52).
