Back and neck injuries are some of the most common work related injuries in the State of Texas. The Texas Division of Workers’ Compensation uses the Fourth Edition of the AMA Guide to Permanent Impairments. For spine injuries the doctor will generally use the Diagnosis Related Estimate Model (DRE). Some injuries resolve by themselves within a few days of the accident. However, most people with this type of injury never seek medical attention. If an injured worker requires follow up medical attention, it is unlikely that a DRE Category I is a proper impairment percentage. For an injured worker to be at a DRE Category I he/she must have no clinical findings, no muscle guarding or history of guarding, no documentable neurologic impairment, no significant loss of structural integrity on lateral flexion and extention roentgenograms, and no indication of impairment related to injury or illness.
