Based on the employee's testimony, the medical records and the other evidence admitted, I find as follows:
- At the time of the hearing James Hillis ("employee") was 59-years-old. The employee obtained his GED after leaving school at the end of the tenth grade. The employee had additional vocational training while employed by the City of Cape Girardeau in automotive, welding and small engines. The employee's work history included two years in the U. S. Army, operating heavy equipment at several landfills, and twenty-nine years of employment with the City of Cape Girardeau working at the landfill and in other departments in the public works area.
- On or about October 1, 2002 the employee and another co-worker were unloading a generator that weighed 75-100 pounds. The employee did not have any symptoms after lifting the generator, but three or four days later he developed pain in his right leg.
- The employee sought treatment for his leg pain from Dr. James Compton. Dr. Compton's October 4, 2002 records indicate the employee was complaining of pain behind his right knee. Dr. Compton notes that that the employee "denies any back pain, hip pain, no recent trauma or injuries" (Employee's exhibit D).
- Dr. Compton initially thought the employee might have a popliteal cyst, and ordered an ultrasound of his knee. The ultrasound was negative, and when the employee's leg pain increased, Dr. Compton ordered an MRI of the employee's low back. The MRI revealed the employee had a right postural lateral disc extrusion at the L5-S1 level that was displacing the S1 nerve root (Employee's exhibit D).
- After reviewing the MRI, Dr. Compton referred the employee to Dr. Dennis Mollman at Neurosurgery and Neurology, LLC in St. Louis. Dr. Mollman's initial record of November 13, 2002 indicates the employee was complaining of right leg pain, and Dr. Mollman stated "no specific onset of the pain is noted in terms of activities". Neither Dr. Compton's nor Dr. Mollman's records make any reference to the employee's L5-S1 herniated disc being related to the employee lifting a generator at work.
- Based on his review of the MRI, Dr. Mollman admitted the employee to St. Luke's Hospital and performed a L5-S1 microdiscectomy on November 13, 2002. The operative record indicates several large disc fragments were removed. Dr. Mollman's narrative indicates that even after he had removed all of the disc material from the disc space that could be removed, "re-inspection of the nerve root showed one more fragment which was dissected and removed with a blunt hook" (Employee's exhibit C).
- After the November 13, 2002 surgery, the employee was examined at Dr. Mollman's office on January 23, 2003 by Nurse Sherry Elze. Although the employee had significant improvement from his "pre-op status", the employee was still complaining of "intermittent low back ache as well as an occasional right lower extremity discomfort that is intermittent in nature and seems to be worse when turning or getting up from a sitting position that usually lasts thirty minutes and occurs daily" (Employee's exhibit C).
- At the time of this visit, the employee was released to return to work on Monday, January 27, 2003 on a light duty basis. The release indicated the employee should do no repetitive bending greater than ten times a day, and no lifting more than 35 pounds (Employee's exhibit C). On his second day of light duty on January 28, 2003, the employee was assigned to a job that required him to pick up trash and put it in a barrel. Although the employee was offered a stick with a nail on the end so he could avoid bending, the employee said the grass was tall and the ground was frozen, so the stick would not work. Rather than contacting his foreman, the employee decided to pick up the trash by bending over and using his hands. After performing this job for two or three hours, the employee was told by another supervisor to stop because of his restrictions. Although the employee continued working that day, the task of bending over and picking up the trash caused the employee's back to ache, and later that night the employee began experiencing back pain and pain in his right leg.
- The employee reported the increase in his symptoms to his employer, and Dr. Mollman subsequently ordered an MRI that was performed in February 10, 2003 at Southeast Missouri Hospital. The MRI showed the prior microdiscectomy at the L5-S1 level and a "small residual disc bulge just to the right of midline, but this is not sufficiently large to exert pressure upon the S1 nerve root" (February 10, 2003 MRI report, Employee's exhibit C; emphasis added).
- After reviewing this MRI, Dr. Mollman scheduled the employee for surgery on February 14, 2003. Dr. Mollman's diagnosis was "recurrent herniated nucleus pulposus, L5-S1, right." Dr. Mollman's operative record indicates he removed scar tissue from the S1 nerve root sleeve, and removed an additional fragment of disc material that had "migrated caudally". In addition to the microdiscectomy, Dr. Mollman also performed a foraminotomy at the L5-S1, right. Dr. Mollman's medical records do not include any history of the employee's January 28, 2003 work activity. There are also no comments by Dr. Mollman to indicate that he felt the employee's second surgery was causally related to the employee's bending activities at work.
- Dr. Mollman's records confirm that on May 1, 2003, the employee required a third surgery to remove another large disc fragment on the right side of the L5-S1 disc space. During the employee's third surgery, Dr. Mollman also performed a L5-S1 fusion with an allograft and pedicle screws. Dr. Mollman's diagnosis was "recurrent herniated nucleus pulposus. L5-S1, right". In the discharge summary, Dr. Mollman referred to the employee's condition as "third recurrent herniated disc, L5-S1". There was no indication from either the employee's testimony or Dr. Mollman's records that this third surgery to remove an additional disc fragment at the L5-S1 level was related to a specific activity or new injury (Employee's exhibit C).
- Dr. Mollman's final surgery on the employee's low back occurred on May 7, 2003. The employee developed a lumbar cerebrospinal fluid leak, and Dr. Mollman explored the lumbar wound and repaired a dural rent (Employee's exhibit C).
- Following these four low back surgeries, the employee did not return to work, and is currently drawing a pension and social security benefits.
- At the time of the hearing the employee continued to have significant complaints and limitations related to his low
back. The employee has daily pain in his low back that reaches a level of six or seven out of ten when he tries to do too much. Both of the employee's legs go to sleep, but his right leg is worse than the left. The employee still has some pain in his right leg that gets worse with movement or walking. The employee is taking Hydrocodone, muscle relaxers and Ibuprofen to relieve his symptoms. As a result of his back and leg pain, the employee has problems sleeping more than four or five hours a night; has difficulty standing, sitting or walking for more than twenty to thirty minutes; avoids vacuuming, house cleaning and yard work; and avoids lifting more than 15 pounds. To obtain relief from his symptoms, the employee takes medication and lies down two or three times a day.
- The employee's claims against the City of Cape Girardeau were both settled on January 26, 2007. The employee's claim for the October 1, 2002 generator incident was not filed until September 27, 2004, and was disputed by the employer-insurer. Although no benefits were paid under the October 1, 2002 claim, as part of the combined compromise settlement, $\ 17,006.00 was paid under the October 1, 2002 claim based on a PPD rating of $121 / 2$ percent of the body as a whole. For the January 28, 2003 claim, the employer-insurer has paid medical expenses and temporary total disability benefits, and the parties allocated $\ 44,215.60 of the total settlement to the 2003 claim based on 33 percent of the body as a whole.
- To support the employee's claim that he had to two separate accidents and injuries that combined to cause him to be permanently and totally disabled, the employee offered the deposition testimony of Dr. David Volarich and Mr. James England. Dr. Volarich examined the employee on July 26, 2004. Dr. Volarich's diagnosis was limited to the January 28, 2003 claim. Dr. Volarich concluded the employee had a recurrent disc herniation at the L5-S1 (Employee's exhibit A, page 15 and 16). On the issue of causation, Dr. Volarich testified that the October 2002 lifting incident "in which he developed back pain radiating into the right leg was the substantial contributing factor causing the initial disc herniation at L5-S1" (Employee's exhibit A, page 15). Dr. Volarich further concluded that the work activities of January 28, 2003 were "the substantial contributing factor causing the recurrent disc herniation at L5-S1" (Employee's A, page 18). Dr. Volarich gave the employee a permanent partial disability rating of 75 percent of the body as a whole and attributed 25 percent of that total to the October 1, 2002 claim and 75 percent to the January 28, 2003 (Employee's exhibit A, page 19). Dr. Volarich felt that these two disabilities combined synergistically (Employee's exhibit, page 20), and concluded that the employee was permanently and totally disabled as a result of both injuries (Employee's exhibit A, page 23).
- Mr. James England is a rehabilitation counselor, and saw the employee on December 22, 2004. Based on his interview of the employee and his review of the medical records, Mr. England concluded that "he is likely to remain totally disabled" (Employee's exhibit B, page 19). Mr. England's response to a second question as to whether the employee was "placeable in employment" was also somewhat equivocal. Mr. England stated "I don't think so, not based on how he described his functioning and how he looked when he was in here. I don't think so." (Employee's exhibit B, page 20).
- In addition to the depositions and reports of Dr. Volarich and Mr. England, the parties also offered the medical records of Dr. Mollman. Dr. Mollman did not believe the employee was capable of returning to his former job. Although he did not believe the employee could perform heavy or medium work, he indicated the employee might be able to perform sedentary or light work. Dr. Mollman gave the employee a ten percent permanent partial disability rating, but offered no opinion to support a finding that the second and third surgeries to remove additional disc fragments were medically causally related to the employee's work activity of picking up trash on January 28, 2003.
