Log Roll/Axial Precaution Question

Hi Guys-

I work in a Trauma ICU and we frequently have patients who are either full axial or log roll spinal precautions.

My question is this, when you turn your patient to the side, how do you prop them up? We have "Macgyvered" a set up by taking a heavy blanket, rolling it and taping it. This works, but is not ideal.

Does anyone out there know of a commercial product that is used in Neuro/Trauma units to offload weight and maintain spinal alignment?

Thanks!
