Operatively Managed Transverse or Short Oblique B1 Periprosthetic Fractures Around a Polished Taper-Slip Femoral Stem Are Associated With Reoperation in One Third of Cases: A Retrospective Cohort Study.

Background: Transverse or short oblique periprosthetic femoral fractures around total hip arthroplasty (THA) stems are typically classified as B1 fractures (stem well-fixed) and usually managed with fixation. These fractures have high non-union rates. This study aimed to identify reoperation rates in patients with operatively managed transverse or short oblique fractures around a cemented polished taper-slip stem and determine any associations with treatment failure.
