Matched-pair cadaveric biomechanical study comparing locked plating (LCP) versus conventional cable-plate fixation (Ogden construct) for Vancouver B1 periprosthetic femoral shaft fractures around cemented hip stems, measuring stiffness across axial, lateral bending, and torsional loading before and after cyclic testing, plus torsional failure loads and cement mantle integrity.
When managing a Vancouver B1 periprosthetic femoral fracture around a well-fixed cemented stem, locked plating offers superior axial and torsional stiffness over the Ogden construct, but the failure mode matters: a locked plate that fails does so catastrophically (longitudinal fracture through screw holes requiring major revision), while a failed Ogden construct loses fixation gradually through cable loosening — factor this trade-off into fixation choice based on bone quality and anticipated loads.
