Based on a comprehensive review of the substantial and competent evidence and the application of the Workers' Compensation Law, I make the following Rulings of Law:
Liability of the Second Injury Fund for permanent partial disability benefits.
Section 287.808, RSMo ${ }^{1}$ provides:
The burden of establishing any affirmative defense is on the employer. The burden of proving an entitlement to compensation under this chapter is on the employee or dependent. In asserting any claim or defense based on a factual proposition, the party asserting such claim or defense must establish that such proposition is more likely to be true than not true.
Section 287.800, RSMo provides:
- Administrative law judges, associate administrative law judges, legal advisors, the labor and industrial relations commission, the division of workers' compensation, and any reviewing courts shall construe the provisions of this chapter strictly.
- Administrative law judges, associate administrative law judges, legal advisors, the labor and industrial relations commission, and the division of workers' compensation shall weigh the evidence impartially without giving the benefit of the doubt to any party when weighing evidence and resolving factual conflicts.
The claimant in a workers' compensation proceeding has the burden of proving all elements of the claim to a reasonable probability. Cardwell v. Treasurer of State of Missouri, 249 S.W.3d 902, 912 (Mo.App. 2008); Cooper v. Medical Center of Independence, 955 S.W.2d 570, 575 (Mo.App. 1997), overruled on other grounds by
[^0]
[^0]: ${ }^{1}$ All statutory references are to RSMo 2006 unless otherwise indicated. In a workers' compensation case, the statute in effect at the time of the injury is generally the applicable version. Chouteau v. Netco Construction, 132 S.W.3d 328, 336 (Mo.App. 2004); Tillman v. Cam's Trucking Inc., 20 S.W.3d 579, 585-86 (Mo.App. 2000). See also Lawson v. Ford Motor Co., 217 S.W.3d 345 (Mo.App. 2007).
Hampton v. Big Boy Steel Erection, 121 S.W.3d 220, 226 (Mo. banc 2003). ${ }^{2}$ The quantum of proof is reasonable probability. Thorsen v. Sachs Elec. Co., 52 S.W.3d 616, 620 (Mo.App.2001); Downing v. Willamette Industries, Inc., 895 S.W.2d 650, 655 (Mo.App. 1995); Fischer v. Archdiocese of St. Louis, 793 S.W.2d 195, 199 (Mo.App. 1990). "Probable means founded on reason and experience which inclines the mind to believe but leaves room to doubt." Thorsen, 52 S.W.3d at 620; Tate v. Southwestern Bell Telephone Co., 715 S.W.2d 326, 329 (Mo.App 1986); Fischer, 793 S.W.2d at 198. Such proof is made only by competent and substantial evidence. It may not rest on speculation. Griggs v. A. B. Chance Company, 503 S.W.2d 697, 703 (Mo.App. 1974). Expert testimony may be required where there are complicated medical issues. Goleman v. MCI Transporters, 844 S.W.2d 463, 466 (Mo.App. 1992). "Medical causation of injuries which are not within common knowledge or experience, must be established by scientific or medical evidence showing the cause and effect relationship between the complained of condition and the asserted cause." Thorsen, 52 S.W.3d at 618; Brundige v. Boehringer Ingelheim, 812 S.W.2d 200, 202 (Mo.App 1991).
Where there are conflicting medical opinions, the fact finder may reject all or part of one party's expert testimony which it does not consider credible and accept as true the contrary testimony given by the other litigant's expert. Kelley v. Banta \& Stude Constr. Co. Inc., 1 S.W.3d 43, 48 (Mo.App. 1999); Webber v. Chrysler Corp., 826 S.W.2d 51, 54 (Mo.App. 1992); Hutchinson v. Tri-State Motor Transit Co., 721 S.W.2d 158, 162 (Mo.App. 1986). The Commission's decision will generally be upheld if it is consistent with either of two conflicting medical opinions. Smith v. Donco Const., 182 S.W.3d 693, 701 (Mo.App. 2006). The acceptance or rejection of medical evidence is for the Commission. Smith, 182 S.W.3d at 701; Bowers v. Hiland Dairy Co., 132 S.W.3d 260, 263 (Mo.App. 2004). The testimony of Claimant or other lay witnesses as to facts within the realm of lay understanding can constitute substantial evidence of the nature, cause, and extent of disability when taken in connection with or where supported by some medical evidence. Pruteanu v. Electro Core, Inc., 847 S.W.2d 203, 206 (Mo.App. 1993), 29; Reiner v. Treasurer of State of Mo., 837 S.W.2d 363, 367 (Mo.App 1992); Fischer, 793 S.W.2d at 199. The trier of facts may also disbelieve the testimony of a witness even if no contradictory or impeaching testimony appears. Hutchinson, 721 S.W.2d at 161-2; Barrett v. Bentzinger Brothers, Inc., 595 S.W.2d 441, 443 (Mo.App. 1980). The testimony of the employee may be believed or disbelieved even if uncontradicted. Weeks v. Maple Lawn Nursing Home, 848 S.W.2d 515, 516 (Mo.App. 1993).

[^0]: ${ }^{2}$ Several cases are cited herein that were among many overruled by Hampton on an unrelated issue (Id. at 224-32). Such cases do not otherwise conflict with Hampton and are cited for legal principles unaffected thereby; thus Hampton's effect thereon will not be further noted.
Section 287.190, RSMo provides for permanent partial disability benefits. Section 287.190.6(2), RSMo provides:
Permanent partial disability or permanent total disability shall be demonstrated and certified by a physician. Medical opinions addressing compensability and disability shall be stated within a reasonable degree of medical certainty. In determining compensability and disability, where inconsistent or conflicting medical opinions exist, objective medical findings shall prevail over subjective medical findings. Objective medical findings are those findings demonstrable on physical examination or by appropriate tests or diagnostic procedures.
The determination of the degree of disability sustained by an injured employee is not strictly a medical question. Landers v. Chrysler Corp., 963 S.W.2d 275, 284 (Mo.App. 1997); Cardwell, 249 S.W.3d at 908 (Mo.App. 2008); Sellers v. Trans World Airlines, Inc., 776 S.W.2d 502, 505 (Mo.App. 1989). While the nature of the injury and its severity and permanence are medical questions, the impact that the injury has upon the employee's ability to work involves factors, which are both medical and nonmedical. Accordingly, the Courts have repeatedly held that the extent and percentage of disability sustained by an injured employee is a finding of fact within the special province of the Commission. Sharp v. New Mac Elec. Co-op, 92 S.W.3d 351, 354 (Mo.App. 2003); Elliott v. Kansas City, Mo., School District, 71 S.W.3d 652, 656 (Mo.App. 2002); Sellers, 776 S.W.2d at 505; Quinlan v. Incarnate Word Hospital, 714 S.W.2d 237, 238 (Mo. App. 1985); Banner Iron Works v. Mordis, 663 S.W.2d 770, 773 (Mo.App. 1983); Barrett v. Bentzinger Bros., 595 S.W.2d 441, 443 (Mo.App. 1980); McAdams v. Seven-Up Bottling Works, 429 S.W.2d 284, 289 (Mo.App. 1968). The fact-finding body is not bound by or restricted to the specific percentages of disability suggested or stated by the medical experts. Cardwell, 249 S.W.3d at 908; Lane v. G \& M Statuary, Inc., 156 S.W.3d 498, 505 (Mo.App. 2005); Sharp, 92 S.W.3d at 354; Sullivan v. Masters Jackson Paving Co., 35 S.W.3d 879, 885 (Mo.App. 2001); Landers, 963 S.W.2d at 284; Sellers, 776 S.W.2d at 505; Quinlan, 714 S.W.2d at 238; Banner, 663 S.W.2d at 773. It may also consider the testimony of the employee and other lay witnesses and draw reasonable inferences in arriving at the percentage of disability. Cardwell, 249 S.W.3d at 908; Fogelsong v. Banquet Foods Corporation, 526 S.W.2d 886, 892 (Mo.App. 1975).
The finding of disability may exceed the percentage testified to by the medical experts. Quinlan, 714 S.W.2d at 238; McAdams, 429 S.W.2d at 289. The Commission "is free to find a disability rating higher or lower than that expressed in medical testimony." Jones v. Jefferson City School Dist., 801 S.W.2d 486, 490 (Mo.App. 1990); Sellers, 776 S.W.2d at 505. The Court in Sellers noted that "[t]his is due to the fact that determination of the degree of disability is not solely a medical question. The nature and
permanence of the injury is a medical question, however, 'the impact of that injury upon the employee's ability to work involves considerations which are not exclusively medical in nature.'" Sellers, 776 S.W.2d at 505. The uncontradicted testimony of a medical expert concerning the extent of disability may even be disbelieved. Gilley v. Raskas Dairy, 903 S.W.2d 656, 658 (Mo.App. 1995); Jones, 801 S.W.2d at 490.
Section 287.220.1, RSMo provides in part:
All cases of permanent disability where there has been previous disability shall be compensated as herein provided. Compensation shall be computed on the basis of the average earnings at the time of the last injury. If any employee who has a preexisting permanent partial disability whether from compensable injury or otherwise, of such seriousness as to constitute a hindrance or obstacle to employment or to obtaining reemployment if the employee becomes unemployed, and the preexisting permanent partial disability, if a body as a whole injury, equals a minimum of fifty weeks of compensation or, if a major extremity injury only, equals a minimum of fifteen percent permanent partial disability, according to the medical standards that are used in determining such compensation, receives a subsequent compensable injury resulting in additional permanent partial disability so that the degree or percentage of disability, in an amount equal to a minimum of fifty weeks compensation, if a body as a whole injury or, if a major extremity injury only, equals a minimum of fifteen percent permanent partial disability, caused by the combined disabilities is substantially greater than that which would have resulted from the last injury, considered alone and of itself, and if the employee is entitled to receive compensation on the basis of the combined disabilities, the employer at the time of the last injury shall be liable only for the degree or percentage of disability which would have resulted from the last injury had there been no preexisting disability. After the compensation liability of the employer for the last injury, considered alone, has been determined by an administrative law judge or the commission, the degree or percentage of employee's disability that is attributable to all injuries or conditions existing at the time the last injury was sustained shall then be determined by that administrative law judge or by the commission and the degree or percentage of disability which existed prior to the last injury plus the disability resulting from the last injury, if any, considered alone, shall be deducted from the combined disability, and compensation for the balance, if any, shall be paid out of a special fund known as the second injury fund, hereinafter provided for.
"To create Second Injury Fund liability, the pre-existing disability must combine with the disability from the subsequent injury in one of two ways: (1) the two disabilities combined result in a greater degree of disability than the sum of the degree of disability from the pre-existing condition and the degree of disability from the subsequent injury; or (2) the pre-existing disability combines with the disability from the second injury to create permanent total disability." Searcy v. McDonnell Douglas Aircraft Co., 894 S.W.2d 173, 178 (Mo.App. 1995).
In order for a claimant to recover against the Second Injury Fund, he or she must prove that he or she sustained a compensable injury, referred to as "the last injury," which resulted in permanent partial disability. Section 287.220.1 RSMo. A claimant must also prove that he or she had a pre-existing permanent partial disability, whether from a compensable injury or otherwise, that: (1) existed at the time the last injury was sustained; (2) was of such seriousness as to constitute a hindrance or obstacle to his employment or reemployment should he or she become unemployed; and (3) equals a minimum of 50 weeks of compensation for injuries to the body as a whole or 15 % for major extremities. Dunn v. Treasurer of Missouri as Custodian of Second Injury Fund, 272 S.W.3d 267, 272 (Mo.App. 2008) (Citations omitted). In order for a claimant to be entitled to recover permanent partial disability benefits from the Second Injury Fund, he or she must prove that the last injury, combined with his or her pre-existing permanent partial disabilities, causes greater overall disability than the independent sum of the disabilities. Elrod v. Treasurer of Missouri as Custodian of the Second Injury Fund, 138 S.W.3d 714, 717-18 (Mo. banc 2004).
"When a claim is made against the Fund for permanent disability compensation, statutory language and case law make it mandatory that the Claimant provide evidence to support a finding, among other elements, that he had a preexisting permanent "disability." (Omitting citations). The disability, whether known or unknown, must exist at the time the work-related injury was sustained, and be of such seriousness as to constitute a hindrance or obstacle to employment or re-employment should the employee become unemployed." Messex v. Sachs Elec. Co., 989 S.W.2d 206, 214 (Mo.App. 1999); Luetzinger v. Treasurer of Mo., 895 S.W.2d 591 (Mo.App. 1995) (emphasis added). "The nature and the extent of the permanent-partial preexisting condition must be proven by a reasonable degree of certainty. (Omitting citation). Expert opinion evidence is necessary to prove the extent of the preexisting disability." Messex, 989 S.W.2d at 215.
Claimant must show that: (1) he or she has preexisting disability that reaches Second Injury Fund threshold, (2) he or she has additional disability from a compensable injury that qualifies for Second Injury Fund threshold, and (3) that his or her preexisting disability combines with his or her present injury to result in a greater degree of disability than the sum of either disabilities alone, ". . . that is, a synergistic enhancement in which
the combined totality is greater than the sum of the independent parts." Searcy, 894 S.W.2d at 178 .
Claimant does not allege permanent total disability in his claim against the Second Injury Fund.
The first issue that must be determined in order to find Second Injury Fund liability is that Claimant sustained additional permanent partial disability from a compensable injury that qualifies for the Second Injury Fund threshold pursuant to Section 287.220.1, RSMo. I find by a preponderance of the credible evidence that Claimant did sustain additional permanent partial disability from a compensable injury on August 1, 2008 that meets the Second Injury Fund threshold requirement pursuant to Section 287.220.1, RSMo.
The parties stipulated, and I find that on or about August 1, 2008, Claimant sustained an injury by accident in Gower, Clinton County, Missouri, arising out of and in the course of his employment for Employer.
Claimant had carpal tunnel release and trigger finger release surgeries by Dr. Anne Rosenthal on his right hand on July 2, 2009 and on his left hand on July 16, 2009. Claimant has numbness, tingling, and an achy pain in his hands. There are times when he tries to limit his work. Claimant has tingling in his hands when he drives. He has trouble sleeping due to numbness in his hands. He has trouble holding light objects like car keys. Claimant has problems lifting because of his hands. His hands are not as strong as they used to be.
I find Claimant's description of his medical treatment, limitations, and complaints to be credible. I find Dr. Poppa's description of Claimant's complaints and limitations to be credible. Claimant's testimony is corroborated by the medical records admitted in evidence at the hearing that substantiate Claimant's medical treatment.
Claimant settled his claim with Employer in the case for 21 % permanent partial disability of the right upper extremity at the 175 week level and 19 % of the left upper extremity at the 175 week level, plus a 10 % combination factor as noted in Exhibit H. Such an agreement to settle does not bind the Commission, but "does serve as relevant evidence of the nature and extent of the employee's permanent disability attributable to the primary injury." Totten v. Treasurer of the State of Missouri, as Custodian of the Second Injury Fund, 116 S.W.3d 624, 628 (Mo.App. 2003)).
Dr. Poppa assessed permanent partial disability of 30 % of the right upper extremity at the 200 week level and 27.5 % of the left upper extremity at the 200 week
level attributable to the injury that occurred on August 1, 2008. I find this assessment of permanent partial disability for the August 1, 2008 injury is not credible.
I find, based on the competent and substantial evidence, including the medical records and reports, and the testimony of Claimant and Dr. Poppa, that as a result of the work injury that Claimant sustained on August 1, 2008, Claimant has sustained an additional 21 % permanent partial disability of the right upper extremity at the 175 week level and 19 % of the left upper extremity at the 175 week level, plus a 10 % combination factor, or 38.5 weeks. In addition, I find that this new permanent partial disability is sufficient to meet The Second Injury Fund threshold required by Section 287.220.1, RSMo.
The next issue to be determined is whether Claimant had preexisting permanent partial disability at the time the August 1, 2008 injury was sustained, and whether his preexisting permanent partial disability was a hindrance or obstacle to Claimant's employment or to obtaining reemployment if he becomes unemployed, and whether the preexisting permanent partial disability equals a minimum of 50 weeks of compensation for injuries to the body as a whole or 15 % for major extremities.
Claimant had arthroscopic surgery to repair a torn meniscus before the August 1, 2008 injury. He took pain medication for his left knee before the August 1, 2008 injury. Bending is difficult for him. He has had steroid injections in his left knee. He still sometimes puts an ice pack on his knee. Claimant reported to Dr. Poppa that he had pain in his left knee.
Claimant saw Dr. Roger Jackson for a surgical consultation before the August 1, 2008 injury. Claimant reported to Dr. Poppa that he had pain in his back and that he had been turned down for a job with a the railroad because of his back. The medical treatment records document that Claimant received treatment for low back complaints on several occasions before August 1, 2008. Claimant received an epidural steroid injection in his low back before August 1, 2008. An MRI lumbar spine report dated January 3, 2007 documents lumbar loss of disk height, annular disk bulging, and mild degenerative changes.
Claimant took Skelaxin, a muscle relaxer, and naproxen for pain before August 1, 2008. He missed some days at work due to his back. He was careful about what he did at work. Claimant had problems sitting, stooping, and bending because of his back before August 2008.
Claimant has had difficulty being around people for a long period of time for fifteen years. He did not like to be in groups when he worked at Ford. He is not good in a group. It is stressful for him to be in a group. Claimant's social phobia problem did not
cause him to miss work. Dr. Trimble prescribed a medication, Celexa, for Claimant's anxiety in 2008. Claimant used Celexa daily from January 2008 until April 2008, but then stopped taking it.
Dr. Poppa found Claimant had preexisting permanent partial disabilities prior to his August 1, 2008 injury regarding his left knee, lumbar spine, and social phobia. Dr. Poppa also found these preexisting conditions constituted a hindrance or obstacle to employment or re-employment if he became unemployed prior to December 18, 2008. I find Dr. Poppa's opinion that Claimant had preexisting disabilities relating to Claimant's back, left knee, and social phobia with anxiety, and that those preexisting conditions constituted a hindrance or obstacle to employment or re-employment if he became unemployed prior to Claimant's August 1, 2008 injury to be credible. However, I find the percentages assessed by Dr. Poppa for Claimant's preexisting left knee, lumbar spine, and social phobia with anxiety disabilities are not credible.
The Second Injury Fund did not present any evidence regarding the issue of preexisting disability.
I find that Claimant had preexisting permanent partial disability 15 % of the left knee at the 160 week level, or 24 weeks, due to his operated left knee, at the time the August 1, 2008 injury was sustained, and that this preexisting permanent partial disability was a hindrance or obstacle to Claimant's employment or to obtaining reemployment if he becomes unemployed. I find this permanent partial disability is sufficient to meet the Second Injury Fund threshold required by Section 287.220.1, RSMo.
I find that Claimant had preexisting permanent partial disability 12.5 % of the body as a whole at the 400 week level, or 50 weeks, due to his low back, at the time the August 1,2008 injury was sustained, and that this preexisting permanent partial disability was a hindrance or obstacle to Claimant's employment or to obtaining reemployment if he becomes unemployed. I find this permanent partial disability is sufficient to meet the Second Injury Fund threshold required by Section 287.220.1, RSMo.
I find Claimant had preexisting permanent partial disability of 5 % of the body as a whole ( 400 week level), or 20 weeks, due to his social phobia or anxiety, at the time the August 1, 2008 injury was sustained, and that this preexisting permanent partial disability was a hindrance or obstacle to Claimant's employment or to obtaining reemployment if he becomes unemployed. I find this permanent partial disability is not sufficient to meet the Second Injury Fund threshold required by Section 287.220.1, RSMo.
While Claimant has experienced discomfort in crowds and being around other people, I find Claimant has failed to prove that his social phobia with anxiety condition has resulted in significant permanent partial disability. Claimant is not taking any
medication and is not undergoing any counseling for this condition. He has worked continuously for many years. He did not miss time from work because of social phobia with anxiety.
I find Dr. Poppa's disability rating pertaining to Claimant's social-phobia is not credible. Dr. Poppa is not a psychologist or a psychiatrist. He performed no psychological testing of Claimant. He evaluated Claimant before Claimant stopped taking Celexa.
Dr. Poppa agreed in his deposition that persons taking Celexa could be highly functioning individuals in the workplace. Dr. Poppa did not review any records indicating Claimant had any restrictions on his work prior to August 1, 2008 due to anxiety or social phobia. He was not aware of any work restrictions prior to August 1, 2008 due to social phobia. He did not review anything indicating Claimant had missed any time from work due to social phobia prior to August 1, 2008. He did not review anything indicating Claimant needed or was given any help or accommodation with his work prior to August 1, 2008 due to social phobia. He did not know how Claimant was affected at work prior to August 1, 2008 from his social phobia.
No evidence was offered at the hearing that Claimant ever received any treatment for social phobia or anxiety from a psychiatrist or psychologist. No evidence was offered at the hearing that Claimant was ever evaluated or tested by a psychiatrist or psychologist for social phobia or anxiety.
Based on the medical records and reports, and the testimony of Claimant and Dr. Poppa, I find that Claimant had preexisting permanent partial disability relating to his left knee, lumbar spine, and social phobia with anxiety at the time his August 1, 2008 injury was sustained. I find that Claimant's preexisting permanent partial disabilities were of such seriousness as to constitute a hindrance or obstacle to Claimant's employment or to obtaining reemployment if he becomes unemployed as required by Section 287.220.1, RSMo. In addition, I find that Claimant had preexisting permanent partial disability of 15 % of the left knee at the 160 week level, or 24 weeks, due to his operated left knee, and 12.5 % of the body as a whole ( 400 week level), or 50 weeks, due to his lumbar spine condition, and 5 % of the body as a whole ( 400 week level), or 20 weeks, due to his social phobia with anxiety condition at the time his August 1, 2008 injury was sustained. The preexisting permanent partial disabilities relating to Claimant's left knee condition and lumbar spine condition are sufficient to meet the Second Injury Fund threshold required by Section 287.220.1, RSMo. The preexisting permanent partial disability of 5 % of the body as a whole for Claimant's social phobia with anxiety condition is not sufficient to meet the Second Injury Fund threshold required by Section 287.220.1, RSMo.
The last issue to be determined is whether Claimant's preexisting permanent partial disability combined with the work injury sustained on August 1, 2008 to result in a greater degree of disability than the sum of either disability alone. I find that it does.
Dr. Poppa concluded that that when one combines the permanent partial disabilities involving Claimant's preexisting conditions with the additional permanent partial disability secondary to his August 1, 2008 work accident, a significant enhancement of the combined disabilities arises above the simple arithmetic sum of the separate disabilities. Dr. Poppa also concluded that "in combination, an enhancement factor of 20 % above the simple arithmetic sum of the separate disabilities was felt to be appropriate."
I agree with Dr. Poppa that the combination of Claimant's permanent partial disability from his preexisting left knee, lumbar spine, and social phobia with anxiety conditions and the additional permanent partial disability secondary to his August 1, 2008 work accident, results in enhancement of the combined disabilities above the simple arithmetic sum of the separate disabilities, and I so find. I find that that the last injury, combined with Claimant's pre-existing left knee and lumbar spine permanent partial disabilities (which meet the minimum thresholds required by Section 287.220.1, RSMo), causes greater overall disability than the independent sum of the disabilities. However, I find Dr. Poppa's opinion that an enhancement factor of 20 % above the simple arithmetic sum of the separate disabilities was appropriate is not credible. I find that the synergistic effect of Claimant's preexisting left knee and lumbar spine disabilities combined with his bilateral upper extremity disability for the August 1, 2008 injury is 10 % above the simple sum of the disabilities, or 11.25 weeks of compensation.
