Periprosthetic Fractures around Polished Collarless Cemented Stems: The Effect of Stem Design on Fracture Pattern

Abstract

This biomechanical study indicates that the CPT and C-Stem create a different fracture pattern under the same loading condition. The C-Stem (a triple tapered stem) may produce lower strain in torsion to the cement mantle of a cemented THA. However, fractures that do occur may be more difficult to treat than those produced around a stem like the CPT subjected to comparable loading.
