Abstract Background Aseptic loosening of glenoid implants is the primary revision cause in anatomic total shoulder arthroplasty (aTSA). While supported by biomechanical studies, impact bone quality, more specifically mineral density (BMD), on aseptic remains unclear. We hypothesized that lower preoperative BMD was associated with implant aTSA. Methods retrospectively included 93 patients (69 fe...

We have compared prospectively the incidence of loosening of 20 femoral stems with a matt surface with that of 20 polished stems of an otherwise identical tapered, non-modular design of Exeter hip replacement. The stems were inserted using the same technique at operation and radiographs showed no difference in the adequacy of the cement mantle or of fixation. All the patients were reviewed regu...
