Section 287.220.2. states: All cases of permanent disability where there has been previous disability due to injuries occurring prior to January 1, 2014 shall be compensated as provided in this subsection. ...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.
In Treasurer of State of Missouri as Custodian of Second Injury Fund v. Witte, et al, 414 S.W.3d 455, 467-468 (Mo.2013), the Court found there must be a single preexisting permanent partial disability that meets the thresholds to trigger SIF's liability and there is no threshold requirement for the last injury. SIF is only liable when there is a preexisting permanent partial disability that meets either the 50 -week threshold for a body as a whole injury or the 15 percent threshold for a major extremity injury. Id. at 468. Additionally, all preexisting injuries must be considered in calculating the amount of compensation for SIF liability. These holdings must be applied to SIF claims in each case. Id. at 466. The Court overruled any case to the extent that it states disabilities from the last injury must meet the thresholds. Hutson v. Treasurer of Missouri as Custodian of Second Injury Fund, 365 S.W.3d 269 (Mo.App.2012).
Claimant asserts SIF is liable for PPD benefits because of the combined effect of her left shoulder injury in March 2010 and her low back injury in May 2007. SIF denied liability. A claimant in a workers' compensation proceeding has the burden of proving all elements of the claim to a reasonable probability. Cardwell v. Treasurer, 249 W.W.3d 902, 911 (Mo.App. 2008). I find Claimant did not meet her burden to prove SIF liability.
I find Claimant's testimony is not credible that she requested an early release from the doctor because she could not afford the co-pays, so she continued to receive help from coemployees for nearly three years with a pain level of seven or eight out of ten, and missed four days' work per month, for an injury she testified occurred on the job.
The evidence contained in the record shows Claimant never reported the incident to her employer, medical records show she improved with treatment, she requested an early release from the doctor, continued to perform the same duties with no physician imposed restrictions for nearly three years, and did not seek additional medical treatment for her low back at any time since June 2007.
After the March 2010 work injury, Claimant started a daycare business and continues to care for infants and young children with only part-time assistants. I find Claimant did not show the low back injury was a hindrance or obstacle to her employment or reemployment and the combined disabilities created synergy.
I find Dr. Musich's conclusion is not persuasive that Claimant's low back and left shoulder injuries create more disability than their simple sum and are a hindrance or obstacle to her personal and professional life. He did not explain how synergy was established, and he was unaware of how much lifting Claimant performed in her day care business.
Also, for the 2007 low-back injury, Dr. Musich diagnosed "acute, turned chronic" lowback pain and rated 20\% PPD of the low back. As discussed above, Dr. Musich did not consider the impact of lifting in the day care business, or weight gain on Claimant's level of low-back pain. However, he did recommend, among other things, that she lose weight.
The [fact finder] is not bound by the experts' exact percentages of disability and is free to find a disability rating higher or lower than that expressed in medical testimony. Tillotson v. St. Joseph Med. Ctr., 347 S.W.3d 511, 523 (Mo.App.2011). This is because a claimant's degree of disability is not solely a medical question. Id. As such, the [fact finder] is not required to accept
the specific rating percentage assigned by [the testifying doctor], notwithstanding the uncontradicted nature of his testimony. Id. at 524.
Furthermore, Dr. Musich testified a 25-pound weight gain may affect Claimant's level of back pain. In 2007, BJC records show Claimant weighed 175 pounds when she received treatment for low-back pain. On March 15, 2010, St. John's records show Claimant weighed 90.719 kg (200 pounds) when she sought treatment for her left shoulder. Medical records dated April 15, 2010 show Claimant weighed 204 pounds. During Dr. Musich's evaluation on June 3, 2014, Claimant weighed 218 pounds. Therefore, based on Dr. Musich's testimony, Claimant's 43-pound weight gain may have impacted her level of back pain between the 2007 injury, the March 10, 2010 work injury, and Dr. Musich's 2014 evaluation.
Based upon medical records and less than credible testimony by Claimant and Dr. Musich, I find Claimant did not meet her burden to show the 2007 low-back injury was a hindrance or obstacle to her employment or reemployment and created synergy with the 2010 left shoulder injury. I further find Claimant sustained 5\% PPD of the low back from the 2007 injury, which does not meet the required threshold to trigger SIF liability.
