Missouri courts have routinely required that the permanent nature of an injury be shown to a reasonable certainty, and that such proof may not rest on surmise and speculation. Sanders v. St. Clair Corp., 943 S.W.2d 12, 16 (Mo.App. S.D. 1997). A disability is "permanent" if "shown to be of indefinite duration in recovery or substantial improvement is not expected." Tiller v. 166 Auto Auction, 941 S.W.2d 863, 865 (Mo.App. S.D. 1997). "Total disability" is defined as the inability to return to any employment and not merely the inability to return to the employment in which the employee was engaged at the time of the accident. Section 287.020.7, RSMo 2000. The test for permanent total disability is whether, given the claimant's situation and condition, he or she is competent to compete in the open labor market. Sutton v. Masters Jackson Paving Co., 35 S.W.3d 879, 884 (Mo.App. 2001). The question is whether an employer in the usual course of business would reasonably be expected to hire the claimant in the claimant's present physical condition, reasonably expecting the claimant to perform the work for which he or she is hired. Id.
Workers' compensation awards for permanent partial disability are authorized pursuant to section 287.190. "The reason for [an] award of permanent partial disability benefits is to compensate an injured party for lost earnings." Rana v. Landstar TLC, 46 S.W.3d 614, 626 (Mo. App. W.D. 2001). The amount of compensation to be awarded for a PPD is determined pursuant to the "SCHEDULE OF LOSSES" found in section 287.190.1. "Permanent partial disability" is defined in section 287.190 .6 as being permanent in nature and partial in degree. Further, "[a]n actual loss of earnings is not an essential element of a claim for permanent partial disability." Id. A permanent partial disability can be awarded notwithstanding the fact the claimant returns to work, if the claimant's injury impairs his efficiency in the ordinary pursuits of life. Id. "[T]he Labor and Industrial Relations Commission has discretion as to the amount of the award and how it is to be calculated." Id. "It is the duty of the Commission to weigh that evidence as well as all the other testimony and reach its own conclusion as to the percentage of the disability suffered." Id. In a workers' compensation case in which an employee is seeking benefits for PPD, the employee has the burden of not only proving a work-related injury, but that the injury resulted in the disability claimed. Id.
In a workers' compensation case, in which the employee is seeking benefits for PPD, the employee has the burden of proving, inter alia, that his or her work-related injury caused the disability claimed. Rana, 46 S.W.3d at 629. As to the employee's burden of proof with respect to the cause of the disability in a case where there is evidence of a pre-existing condition, the employee can show entitlement to PPD benefits, without any reduction for the pre-existing condition, by showing that it was non-disabling and that the "injury cause[d] the condition to escalate to the level of [a] disability." Id. See also, Lawton v. Trans World Airlines, Inc., 885 S.W.2d 768, 771 (Mo. App. 1994) (holding that there is no apportionment for pre-existing nondisabling arthritic condition aggravated by work-related injury); Indelicato v. Mo. Baptist Hosp., 690 S.W.2d 183, 186-87 (Mo. App. 1985) (holding that there was no apportionment for preexisting degenerative back condition, which was asymptomatic prior to the work-related accident and may never have been symptomatic except for the accident). To satisfy this burden, the employee must present substantial evidence from which the Commission can "determine that the claimant's preexisting condition did not constitute an impediment to performance of claimant's
duties." Rana, 46 S.W.3d at 629. Thus, the law is, as the appellant contends, that a reduction in a PPD rating cannot be based on a finding of a pre-existing non-disabling condition, but requires a finding of a pre-existing disabling condition. Id. at 629, 630. The issue is the extent of the appellant's disability that was caused by such injuries. Id. at 630.
Various physicians provided forensic medical opinions regarding the claimant's disabilities from the last injury alone. Dr. Volarich opined that the April 2007 accident was the prevailing factor causing the aggravation of his pre-existing lumbar syndrome including a disc protrusion at L4-5 centrally and a bulge at L5- S1 as well as causing a new bulge at L3-4, all of which required conservative treatment. He opined that the claimant sustained a 35 % permanent partial disability to the body as a whole related to the April 22, 2007 injury and had a 25 % preexisting disability to the lumbar spine and 65 % pre-existing disability to each shoulder. He deferred to a psychiatrist for any disability relating to the claimant's depression. He also opined that the claimant was permanently and totally disabled as a result of the work injury of April 22, 2007 combined with his pre-existing medical conditions as well as his depression and that the claimant was unable to engage in substantial gainful activity nor could he perform in an ongoing working capacity in the future. Dr. Wayne opined that the claimant suffered a 6 % permanent partial disability related to the April 22, 2007 injury alone and placed no restrictions relative to that injury alone. He offered no forensic medical evidence regarding the claimant's pre-existing conditions.
Dr. Stillings opined that the April 22, 2007 work injury was the prevailing factor in causing the claimant to experience a mood disorder with an associated 20 % psychiatric permanent partial disability, an anxiety disorder with an associated 10 % psychiatric permanent partial disability, and a pain disorder associated with a 10 % psychiatric permanent partial disability. Dr. Stillings opined that the claimant's pre-existing adjustment disorder would account for a 7.5 % permanent partial disability and that his pre-existing personality disorder would provide another 10 % permanent partial disability. Dr. Stillings opined that the claimant was totally disabled from gainful employment.
Looking at the claimant's employability, Dr. Volarich and Dr. Stillings opined that the claimant is permanently and totally disabled as did Mr. England. Mrs. Kisslinger-Abram opined that the claimant cannot return to his prior position with this employer, is not employable with the restrictions established by either Dr. Volarich or Dr. Stillings, and is not employable if he needs to lie down five to six times per day. The great weight of the evidence is that the claimant is unemployable in the open labor market.
The Second Injury Fund argued in its well written brief that the claimant had no preexisting disabilities, because the claimant testified that his low back was pain free before the accident and the claimant had no restrictions or limitations regarding work or other major activities. In essence, the Second Injury Fund suggests that the claimant's pre-existing conditions were not disabling and did not constitute permanent partial disabilities. On the other hand, Dr. Volarich and Dr. Stillings opined that the claimant had substantial pre-existing permanent partial disabilities to his low back and shoulders as well as psychiatric disabilities. Dr. Volarich was the only forensic expert to focus on the combination of the claimant's pre-existing permanent partial disabilities with his permanent partial disabilities from the 2007 accident. He opined that the claimant was permanently and totally disabled as a result of the work injury of April 22, 2007
combined with his pre-existing medical conditions as well as his depression and that the claimant was unable to engage in substantial gainful activity nor could he perform in an ongoing working capacity in the future.
Dr. Wayne and Dr. Coyle opined that the April 2007 accident was a relatively minor sprain/strain to the claimant's low back, but was superimposed upon diffuse multi-level degenerative abnormalities in the lumbar spine. Dr. Volarich testified that the claimant was unable to return to work because of the combination of his prior injuries and the 04/22/07 work injury. See Dr. Volarich deposition, page 9. Mr. England testified that the claimant's inability to work from a vocational standpoint is from a combination of his medical problems. See England deposition, page 19. He also testified that the claimant's need to recline periodically during the day compels a conclusion that the claimant is not employable in the open labor market. He also testified that, assuming Dr. Volarich's forensic conclusions, the restrictions for the claimant's low back condition are "just due to the primary injury and if that's the case then that could totally disable him regardless of the shoulders and the other things." See England deposition, page 17. Donna Kisslinger-Abram concluded that it is doubtful that the claimant can obtain and sustain a new job, but that difficulty with returning to work "is a combination of his primary work history along with his other medical and psychological conditions based on the reported ongoing problems he delineated, his pre-existing physical restrictions, and level of functioning at the time of his work injury." See Kisslinger-Abram deposition, pages 59-60.
The essential question is whether the claimant's severe low back restrictions requiring him to recline periodically during the day for pain relief resulted solely from the last accident alone. Most of the focus is on the forensic medical evidence which the attorneys have construed to result in different conclusions. However, the weight of the evidence compels a conclusion that the claimant's low back condition resulted from a synergistic combination of the claimant's low back disability from the April 2007 accident and the substantial structural defects in his low back from the prior condition. The structural defect caused serious disabling features before the claimant received traction type treatment using VAX-D. However, the treatment left him pain free but not necessarily nondisabled. Dr. Volarich opined that the claimant had substantial preexisting disability based on his medical history:
I asked Mr. Rook about difficulties he had with his back prior to 4/22/07 and he admitted that although he had some problems in the past, after using the decompression treatments his pain had resolved and he was markedly improved. He was very cautious however and limited himself to approximately 60 pounds maximum weight to lift and he was very careful to use proper body mechanics. He was quick to ask for help and in general had learned to slow down and take his time whereas previously he was always in a rush. He only would take an occasional Tylenol and did not miss time off work or have any physician imposed restrictions. See Dr. Volarich deposition, Exhibit 2, pages 6, 7.
This suggests a significant disability involving the claimant's lifting limitations. The prior medical records disclose a significant low back defect from the March 17, 2004 lumbar MRI that revealed disc space narrowing at L5-S1 with a central herniation and disc bulging with a disc osteophyte complex that narrowed the intervertebral foramen. At L4-5 there was a central herniation with a posterior bulge that caused a concave defect on the thecal sac. A sensory nerve
conduction test on March 29, 2004 showed a mild deficit at L4 to the left, a moderate deficit bilaterally at L5, a very severe deficit to the right at S-1. See Exhibit D.
Based on the evidence in the record, Dr. Volarich's evaluation of pre-existing permanent partial disabilities is accurate. Thus, the claimant is permanently and totally disabled as a result of the combination of his pre-existing disabilities and the primary low back injury. Accordingly, liability for permanent and total disability benefits rests with the Second Injury Fund. As of the date of maximum medical improvement, September 12, 2007, the Second Injury Fund is liable for permanent total disability benefits going forward for the period of the claimant's lifetime. However, the employer bears liability for the 40 % permanent partial disability to the claimant's body as a whole.
