Proximal femur anatomy-implant geometry discrepancies.

ABSTRACT:

Objectives

Due to ongoing concern about femur anatomy-implant mismatches, this cross-sectional study aimed to create a geometric femur profile and used it to identify and quantify possible mismatches between femur anatomy and cephalomedullary nail dimensions. The work further aimed to assess whether patient demographics affect anatomy-implant coherence.

Methods

One hundred skeletally mature complete femur computer tomography (CT) scans were collected and exported to software enabling landmark placement and measures with multiplanar reconstruction techniques.

Results

Clinically relevant anatomy-implant discrepancies included the femur neck and shaft axis offset 6.1 ± 1.7 mm (95% CI [5.7-6.4]), femur radius of curvature 1.2 ± 0.3 m (95% CI [1.1-1.2]), femur anteversion
