Mr. Angus testified on his own behalf and presented the following exhibits, all of which were admitted into evidence without objection:
Exhibit A - Deposition, P. Brent Koprivica, MD, April 23, 2009
Exhibit B - Deposition, Mr. Michael J. Dreiling, April 21, 2009
Exhibit C - Stipulation for Compromise Settlement, Dec. 18, 2008
The Fund did not present any exhibits or call any witnesses.
Based on the above exhibits and the testimony of Mr. Angus, I make the following findings. Mr. Angus is a single, 54-year old male, who lives with his 85 -year old father in Holden, Missouri. He received his high school diploma in 1974 and completed a course for realestate sales. See, Claimant's Exhibit B at 14. Mr. Angus apparently never utilized his real estate training, however, and, instead has worked in manual labor jobs.
The employer in this case, ATK Alliant Techsystems, owns an ammunition plant in Independence, Missouri that has been in operation - albeit by different owners - for many years. In fact, Mr. Angus first went to work at the plant in 1981 when it was owned by Remington. Mr. Angus continued working at the plant until 1996. During this 15-year employment period Mr. Angus' jobs included machine operator, truck driver, and forklift driver. Due to a work slowdown, Mr. Angus left the plant and started a tree-trimming business which he operated from 1996 through 2001. With the advent of the Iraq War, the ammunition plant (now owned by ATK) ramped up production and Mr. Angus returned to work there.
Mr. Angus worked for ATK from August 13, 2001 through February 7, 2004. Mr. Angus' job primarily required him to push "buggies" filled with ammunition; the buggies typically weighed from 500 to 1,000 pounds. In addition, Mr. Angus had to carry "tote pans"
that contained defective ammunition; the pans were approximately 3.5 feet long by 1 foot wide and 8 inches deep and weighed (full) around 50 pounds.
Prior to either periods of employment with ATK, Mr. Angus had sustained, in 1974, a severe motor cycle accident that resulted in a compound fracture to his left femur and required a 3-4 month hospitalization. After recovering from this accident, Mr. Angus was able to walk, run, hunt, swim, and water ski.
Throughout his entire work life Mr. Angus has had the same primary care doctor, William E. Whitley, DO. In August 2002 Mr. Angus began experiencing joint pain for which he sought treatment from Dr. Whitley. On August 23, 2002, Dr. Whitley diagnosed Mr. Angus as suffering from rheumatoid arthritis. See, Claimant's Exhibit A at 13:4. Within just one month, on September 21, 2002, Dr. Whitley restricted Mr. Angus to no more than four hours per day of carrying with a break every two hours. Id. at 64. In July 2003, Dr. Whitley diagnosed Mr. Angus with GERD and chronic pain syndrome. Dr. Whitley noted depression on September 18, 2003. Ultimately, on February 7, 2004, Dr. Whitley put Mr. Angus on a leave of absence. Id.
Notwithstanding his severe and debilitating rheumatoid arthritis, Mr. Angus filed a Claim for Compensation on January 18, 2005 alleging that his "entire back has failed and legs have lost strength" due to pushing the ammunition buggies. See, Claim for Compensation, items 7 and 8 (Division file). The Employer timely filed its answer specifically denying notice, causation, or that the employee had sustained a compensable accident. See, Answer filed February 9, 2005, item 9 (Division file). The employer never provided Mr. Angus either with any treatment or temporary disability benefits. Ultimately, on December 18, 2008, Mr. Angus settled with the employer for a $\ 24,987.60 lump sum based on 18 % disability to his body-as-a-whole. See, Claimant's Exhibit C, item 7. The settlement noted that the disputes between the parties included "nature and extent; medical - past and future; and all issues not specifically admitted herein". Id.
P. Brent Koprivica, MD examined Mr. Angus on September 16, 2008 at his attorney's request. Dr. Koprivica authored a narrative report of the same date, and testified by deposition taken April 23, 2009. Dr. Koprivica noted that:
- Dr. Mark Killman opined that Mr. Angus' work activities were not the prevailing factor or even a significant contributor to his disability. Instead, Dr. Killman believed that Mr. Angus's problems were related to his inflammatory arthritis. See, Claimant's Exhibit A at 13:22-14:4.
- He remembered Mr. Angus "because of the severity of his disease" (Id. at 15:24) and even photographed his disfigured knee and finger joints (Id. at 23:19). (The photos are found at page 75 .)
- Mr. Angus suffered from "degeneration in his joints that was more wear-andtear type of degeneration." Id. at 10:20.
- Mr. Angus has "severe disability from rheumatoid arthritis" that is a "... major contributor to his disability presentation." Id. 18:4-6.
- Mr. Angus has a family history of rheumatoid arthritis. Id. at 19:8.
- Mr. Angus' rheumatoid arthritis requires him to take narcotic medication to manage his pain. Id. at 19:18.
- Mr. Angus' rheumatoid arthritis has deformed his spine so greatly that he is unable to stand up straight (Id. at 20:6) such that Dr. Koprivica did not think it would be safe for him to attempt to bend over (Id. at 21:5).
- Mr. Angus' rheumatoid arthritis-related hand problems are so profound that he was unable even to do normal grip strength testing (Id. at 20:8-13, and 52:23).
- There is no ". . . relationship between the rheumatoid arthritis and his workplace exposure." Id. at 25:12-13.
- It was possible that Mr. Angus' "rheumatoid arthritis alone would be sufficient to totally disable him." Id. at 52:18-21.
In addition, Dr. Koprivica acknowledged that it was extremely difficult to apportion the effects of rheumatoid arthritis and osteoarthritis. He noted this was true ". . . because there's overlap between similar - same joint involvement, from the degenerative process and the rheumatoid arthritis, that overlap is going to make it virtually impossible to do." Id. at 38:10-14.
Dr. Koprivica also acknowledged that it was "obvious" that Mr. Angus' rheumatoid arthritis was worse in 2008 (when he first examined him) than it was in 2004 (when he could no longer work). Despite this admission, his confession of the difficulty in apportioning Mr. Angus' rheumatoid arthritis related problems from his osteoarthritis problems, AND t
