Study protocol: The DUALITY trial—a register-based, randomized controlled trial to investigate dual mobility cups in hip fracture patients

Figures & data

Table 1. Screening questions within the SFR platform

This patient is eligible for inclusion in the Duality trial for randomization to receive a standard cup or a dual mobility cup for a Garden 3–4 fracture. Answer the following questions for screening.

Is the patient already treated for the fracture? Is the patient suitable for a total hip arthroplasty? Can both treatments (standard and dual mobility cup) be performed for this patient? • Has the patient given informed consent?
