Table 3 Timescale of enrolment, interventions and follow-ups for patients

From: Scaphoid Waist Internal Fixation for Fractures Trial (SWIFFT) protocol: a pragmatic multi-centre randomised controlled trial of cast treatment versus surgical fixation for the treatment of bi-cortical, minimally displaced fractures of the scaphoid waist in adults

  1. aWhere possible the CT should be done before randomisation, if this is not feasible it must be scheduled before surgery and must be done within two weeks of a patient’s injury
  2. bPatients allocated to surgery must receive this within two weeks from when the patient presents to A&E or other point of contact (e.g. walk-in centre, cottage hospital)
  3. cPatients are initially put into plaster cast for 6 to 10 weeks. If non-union is confirmed on X-rays/CT at 6 or 12 weeks urgent surgical fixation will be performed
  4. dThese X-rays/CT are those routinely collected whereas at the other time-points are compulsory
