Abstract

Objective The main objective of the present study was to evaluate the clinical and radiographic results of the Logical (Baumer, Mogi Mirim, SP, Brasil) cementless femoral stem in primary total hip arthroplasties (THAs).

Methods A retrospective cohort study of 632 patients submitted to primary THA with the Logical cementless femoral stem. The study period was between January 2004 and January 2015. The outcome defined to evaluate the survival of the stem was the clinical and radiographic indication of the revision hip arthroplasty or the actual revision of the femoral stem for any cause.

Results Kaplan-Meier survival curves were estimated at > 95%, with a follow-up ranging from 2 to 13 years. There was a low incidence of transoperative periprosthetic fractures (0.02%). No axial migration or cortical bone atrophy was observed in the radiographic sample evaluated.

Conclusions In the intermediate follow-up, there was excellent survival of the Logical cementless femoral stem. Although long-term studies are still awaited, this implant appears to be safe and promising to be used for primary THAs.
