The posterior approach reduces the risk of thin cement mantles with a straight femoral stem design.

Background And Purpose: The properties of the cement mantle around a prosthesis are important. We investigated whether the surgical approach to the hip influences the quality and thickness of the cement mantle when using a straight femoral stem design.

Methods: In a consecutive multi-surgeon series, we reviewed the radiographs of 270 patients after cemented Exeter total hip arthroplasty.

Anatomic stem design reduces risk of thin cement mantles in primary hip replacement.

Purpose: To analyse the influence of femoral stem design in the lateral plane (anatomic vs. straight) on the cement mantle quality.

Method: In this consecutive multi-surgeon radiographic study we determined, Dorr grading, cement mantle quality (Barrack) and mantle thickness using Gruen zones 1–14 in 280 primary cemented total hip replacements, divided into two groups (140 anatomic Biomet Olympia, 140 straight Exeter Universal Series).
