Clinical Evaluation of a New Total Hip Prosthetic Design: 100 Consecutive Cementless Total Hip Arthroplasties Using Sulzermedica's "Natural Hip" With Two- to Six-Year Clinical and Radiographic Follow-Up

ABSTRAKT

One hundred consecutive total hip arthroplasties were performed on 96 patients (age range 30 to 82 years) using the "Natural Hip" design of Sulzermedica (Austin, Texas). Follow up of the clinical and radiographic results with a minimum of 2 years is reported. Twelve patients were excluded for the lack of follow-up data, leaving 88 hips to study. All but three of the stems were used cementless, regardless of patient age or osteoporosis, as long as surgical stability was obtained. No stems were revised for loosening or pain. The only revisions were for infection (2), and minimal bone loss occurred with removal of this proximal ingrowth stem. Thigh pain was present in only one patient at 2 years, and none with longer follow-up. There were no cases of osteolysis, proximal stress shielding, or aseptic radiolucent lines with the cementless stems.
