The Pronator Quadratus Muscle After Volar Plating: Ultrasound Evaluation of Anatomical Changes Correlated to Patient-Reported Clinical Outcome.

ABSTRACT: Background: Repair of the pronator quadratus (PQ) muscle with sutures has been reported durable after volar plating of distal radius fractures (DRF). It is unclear how the muscle reacts if not repaired and if a retracted muscle correlates to worse functional outcome or complications. In this study, we use ultrasound to investigate the anatomy of the PQ muscle after volar plating with PQ repair or nonrepair and correlate the ultrasound findings with patient-reported outcome. Methods: Participants were recruited from a clinical trial where they were randomly allocated to repair or nonrepair of the PQ muscle after volar plating of DRF. The participants and radiologist were blinded to group allocation. Ultrasound imaging of both fractured and contralateral wrists was performed 3
