Bigart KC, Nahhas CR, Ruzich GP, et al. - This study was sought to evaluate a relationship between a specific femoral morphology and an increased risk of acute, periprosthetic fracture after cementless total hip arthroplasty (THA). Researchers applied an institutional arthroplasty registry to distinguish 32 primary, cementless THAs revised for acute, postoperative periprosthetic fracture (“fracture” cohort) within 3 months of the index procedure. Individuals were matched in 1:2 ratio to 64 THAs without fracture (“control” cohort) for age, body mass index, gender, and stem design. The results of this research displayed that individuals sustaining an acute, periprosthetic fracture with cementless femoral fixation after THA had thinner distal cortices and a lowered meta-diaphyseal taper.
