Comment about appropriate level of ISV 5 to 15 An ISV at or near the top of the range will be appropriate if— there is a disc prolapse for which there is radiological evidence at an anatomically correct level; and there are symptoms of pain and 3 or more of the following objective signs that are anatomically localised to an appropriate spinal nerve root distribution— sensory loss; loss of muscle strength; loss of reflexes; unilateral atrophy; and the impairment has not improved after non-operative treatment. An ISV of about 10 will be appropriate if there is a fracture of a vertebral body with up to 25% compression, and ongoing pain. An ISV at or near the bottom of the range will be appropriate for an uncomplicated fracture of a posterior element of 1 or more of the vertebral segments, for example, spinous or transverse processes, without neurological impairment.
