The employee was born in 1958. The last day he worked was February 16, 2004, the day of the primary accident. The employee had several pre-existing conditions. In 1986, when he was working for Biltwell, he fell down steps and injured his lower back and neck. The employee saw Dr. Krettek in August of 1986 for low back pain and bilateral lower extremity pain and numbness. The employee injured himself on July 2, 1986 when he landed on his sacrum. Dr. Krettek admitted the employee to the hospital for a low back myelogram and CT scan and diagnosed a L4-5 herniated disc. Surgical alternatives including chemonucleolysis and discectomy were discussed.
The employee saw Dr. Holder in August of 1986 for the L4-5 herniated disc. Dr. Holder thought the employee should have a surgical laminectomy or a chemonucleolysis under local anesthesia. Dr. Holder performed a chemonucleolysis of the L4-5 disc. In October, the employee told Dr. Holder that his discomfort in his legs has been relieved.
In January of 1987 the employee saw Dr. Krettek who noted that the employee wanted to avoid having an open surgical discectomy of the L4-5 disc and had a chemonucleolysis by Dr. Holder. Subsequently, the employee continued to have low back pain and bilateral lower extremity aching sensations but did not have the same pre-operative numbness. Due to neck pain, Dr. Krettek ordered a cervical and thoracic MRI which showed a herniated disc at C5-6. In February, a cervical myelogram with post myelogram CT showed a large central disc herniation
at C5-6 with mild compression of the spinal cord and a central bulging disc at C6-7. In February of 1987 Dr. Krettek performed a C5-6 anterior discectomy and fusion.
In April of 1987 the employee saw Dr. Krettek with continued neck and low back pain with radiating pain to both thighs particularly after prolonged sitting and bending. Dr. Krettek prescribed a different muscle relaxant and Elavil for neck stiffness and difficulty sleeping. Dr. Holder noted the employee was doing well with the chemonucleolysis; was remarkably improved with regard to his lower back; and may enter vocational rehabilitation or return to gainful employment with restrictions of no lifting more than 35 pounds. In June, Dr. Holder stated the employee could be considered to be employed in a limited capacity provided he does not have to lift more than 35 pounds on a repeated basis. The employee saw Dr. Krettek and additional physical therapy was ordered. The employee had restrictions of no standing greater than one hour, alternating with sitting and no continuous walking on concrete and no work above shoulder level. He recommended vocational rehabilitation and prescribed medications including Darvocet.
In July, Dr. Holder talked to the employee by telephone about vocational rehabilitation and training. The employee was attempting to get the state to send him to computer school. Dr. Holder stated that the employee should get into an occupation which did not allow heavy manual labor due to the low back and neck surgery. It was Dr. Holder's opinion that the employee was at maximum benefit with regard to the lower back and his final limitation was increased to a lifting capacity of no more than fifty pounds which would probably be a permanent condition for both his back and neck. It was Dr. Holder's opinion that the employee sustained a 15\% permanent partial disability of the body as a whole due to the herniated disc and subsequent chemonucleolysis procedure. It was possible that the employee may have future treatment.
In August of 1987, the employee and Dr. Holder discussed by phone a fifty pound capacity working on light duty on a permanent basis. In September, Dr. Holder released the employee to be seen on an as needed basis. Dr. Krettek stated the employee was overall improving slowly with his neck, but had some minor current neurologic damage due to his cervical disc disease. The employee wished to return to work previously but was told there was no light duty.
In October of 1987, the employee settled his claim by compromise settlement in Injury Number 86-77722. The employee was paid $555 / 7$ weeks of temporary total disability. The settlement was for 15 % permanent partial disability of the body as a whole referable to the neck and 15 % permanent partial disability of the body as a whole referable to the low back.
In July of 1990, the employee called Dr. Holder for his lower back. Dr. Holder noted that occasionally the employee called for a limited amount of medication. The employee requested Darvocet and six tablets were prescribed. In September of 1990, the employee called and six more Darvocet tablets were prescribed. Four days later the employee saw Dr. Holder who noted that since the August 1986 injection for the L4-5 disc he did very well, had changed jobs several times and periodically required some pain medication.
