Effect of screw thread type on implant-related complications following femoral neck fracture fixation in non-geriatric adults: a multicenter, retrospective cohort study.

ABSTRACT:

Introduction

This study compared implant-related complications after femoral neck fracture fixation using partially vs. fully threaded cannulated screws in non-geriatric patients.

Methods

This retrospective cohort study included 1,035 patients with femoral neck fractures aged 18-60 years treated with cannulated screws from 2012 to 2022. Patients were followed until clinical failure-defined as the occurrence of any of the following: implant cut-out, femoral neck shortening, nonunion, or avascular necrosis-or for a minimum of 2 years. Patients were categorized into two groups according to thread type and balanced using propensity score matching. The primary outcome was the clinical failure rate. Subgroup analyses were performed for comminuted vs. non-comminuted fractures.
