The findings of fact and stipulations of the parties were recounted in the award of the administrative law judge; therefore, the pertinent facts will merely be summarized below.
In 1993, employee sustained an injury at work when he was thrown onto the concrete floor following an explosion. As a result, he injured his neck and right upper extremity. Following a right carpal tunnel release
and two cervical fusions, which were performed by Dr. David Kennedy, employee returned to work with Dr. Kennedy's permanent restrictions of no lifting greater than forty pounds, no vibrating tools, no welding, and no climbing ladders. Dr. Robert Margolis, a physician who provided an Independent Medical Evaluation of employee on April 7, 1998, agreed with Dr. Kennedy as to employee's permanent work restrictions and provided said endorsement in his report.
Employee testified that following the 1993 injury and subsequent surgeries, he was no longer able to participate in the recreational activities he once enjoyed, which included bow hunting, jogging, volleyball and softball. In addition, he testified that after the injury he wore a back brace to work.
As a result of the 1993 injury, employee received a settlement based on 40\% permanent partial disability of the neck, 15 % permanent partial disability of the right hand, and 10 % permanent partial disability of the back.
Despite employee's restrictions and limitations incurred as a result of the 1993 injury, he was able to keep his welding certification by performing one certified weld every six months. By keeping his welding certification, his employer allowed him to maintain the same level of income. Employer further accommodated employee by only requiring him to perform jobs he was able to do. Employee testified that his foreman would assign him jobs, but if he could not do the jobs, he would let them know and they would reassign him. Employee stated that had his employer not provided the accommodations they did following the 1993 injury up until the primary injury, he would not have been able to remain employed by employer.
On February 7, 2005, the primary injury occurred. The injury occurred while employee was cleaning up at the end of the day and stepped out of a shower onto a rubber mat to dry off. As employee walked to his locker, he stepped on something sharp, reached down to pull it out of his foot and fell onto the hard concrete floor. He injured his neck and right upper extremity. Following this injury, employee had two additional cervical fusions performed by Dr. Kennedy on April 22, 2005 and December 15, 2005, respectively. As a result of this injury, employee received additional compensation based on 32\% permanent partial disability of the neck. Employee remained off work for almost a year.
Following this primary injury, Dr. Kennedy imposed additional permanent restrictions on employee's work activities. These restrictions included no lifting greater than ten pounds, no repetitive overhead use or lifting, and no overtime. Employer worked with employee to accommodate him, but once he was able to return to work on April 5, 2006, his duties were relegated to merely pushing a broom 90 % of the time. Employee was allowed 45 minute to 2 hour breaks at a time. However, eventually employee could no longer continue working, even with the breaks and other accommodations.
On November 8, 2006, employee was seen by Dr. David T. Volarich for the purpose of obtaining an Independent Medical Evaluation. Dr. Volarich opined that employee is permanently and totally disabled as a direct result of the work-related injury of February 7, 2005, in combination with his preexisting medical conditions.
Dr. Volarich testified that when the primary injury occurred employee had 45\% preexisting permanent partial disability of the body as a whole rated at the cervical spine. Dr. Volarich stated that the preexisting 45\% permanent partial disability accounted for employee's neck pain syndrome, lost motion, and continuing upper extremity paresthesias with neck stiffness and occasional headaches. Dr. Volarich further testified that employee had 15 % preexisting permanent partial disability of the right upper extremity at the wrist due to the carpal tunnel syndrome that required open carpal tunnel release. Said 15 % rating accounted for pain and paresthesias in the dominant hand. Lastly, Dr. Volarich testified that employee had 15\% preexisting permanent partial disability of the body as a whole rated at the lumbosacral spine due to his chronic lumbar syndrome causing back pain and lost motion.
As for the February 7, 2005 primary injury, Dr. Volarich testified that said injury, in isolation, amounted to "a 50 % permanent partial disability of the body as a whole rated at the cervical spine due to the recurrent disk herniation at C4-5 and C5-6 that required two surgical repairs...." The rating accounts for the primary injury's contribution to employee's neck pain syndrome, lost motion, right upper extremity weakness, and continuing radicular symptoms in the right arm, in addition to his headaches.
On December 13, 2006, employee was seen by Mr. James England, employee's vocational consultant. Mr. England testified that employee was unemployable in the open labor market due to a combination of problems he had. The specific factors Mr. England listed as contributing to employee's unemployability were the difficulty employee had functioning, the affects of the medication he was taking, his inability to get through the day without lying down periodically, and his stiff appearance. Based on employee's day-to-day functioning, Mr. England does not feel employee would be able to sustain any type of work in the long-run.
Most importantly, Mr. England testified that he is of the opinion that employee's unemployability is attributed to the combination of employee's February 7, 2005 injury and his preexisting injuries.
Both Dr. Volarich and Mr. England reviewed all treatment records, and examined employee.
Dr. David Robson, a spine specialist, reviewed employee's medical treatment records and determined that employee is permanently and totally disabled as a result of the February 7, 2005 injury alone. Dr. Robson did not meet or examine employee prior to issuing his opinion.
