Why are individuals with severe rheumatoid arthritis and osteoporosis contraindicated for spinal traction that provides significant distractive forces?

What will be an ideal response?

? Rheumatoid arthritis commonly causes the joint support structures to be excessively lax following periods of inflammation. Joint hypermobility may be increased with superimposed distractive forces.
? Osteoporosis creates a decrease in spinal bone density and may decrease its ability to withstand distractive forces.
? Both conditions may result in instability of the odontoid process in the C2 vertebrae during cervical traction.
