Staged bilateral total hip arthroplasty using rough and smooth surface femoral stems with similar design: 10-year survivorship of 48 cases.

Background: Various studies have reported good long-term results using femoral stems with either smooth or rough surfaces. In this retrospective cross-sectional survivorship study, we reviewed the 10-year results of 51 bilateral staged cemented total hip arthroplasties using the Harvard or the Charnley femoral stems-which have almost similar geometry but a different surface finish.

Methods: 51 patients were reviewed at median interval of 10 (Harvard group) and 11 years (Charnley group) after the primary operation.

Femoral cement pressurization in hip arthroplasty: a laboratory comparison of three techniques.

Background: Several cementing techniques are used for the proximal femur.

Material And Methods: We evaluated 3 femoral cement pressurization techniques (standard, pressurizer in situ, and thumb pressurization) in 12 plastic femurs, with 4 sets of observations for each technique. Intramedullary pressure readings were obtained using proximal and distal pressure monitoring transducers.
