Fractured HIP patient - Need question answered

I manage a general med/surg was that has some (mostly geriatric) orthopedics. We often have fractured hip patients who stay pre op for at least 24 hours prior to going to OR for repair. We just had a fractured hip patient who was scheduled for a bipolar prothesis as a repair since his fracture broke the femoral head. Several of my nurses moved him (with his hip splinted) from the bed to a gurney on a slide board and the OR supervisor insists that we violated a common standard of care that you never move a fractured hip. Our Nurse practitioners who cover these patients disagree and believe that the patients need to be moved to prevent numerous complications (i.e. dvt's, pneumonia). I understand that you would certainly stablilze a fracture by splinting but we move patients from bed to gurney to take to Xray, CAT scan and we turn them Q2 while in bed. Is there anyone that can tell me what you do, as this had gone to the Chief Nurse who wants me to look for references and standards to support our practice. Help!
