Enrika Fox v. Missouri Department of Corrections

Decision date: May 1, 2018Injury #08-02543316 pages

Summary

The LIRC reversed the administrative law judge's denial of Second Injury Fund liability, finding that the employee's work-related injuries to the lumbar spine, cervical spine, and right shoulder combined synergistically with preexisting conditions (right knee patellofemoral syndrome, bilateral carpal tunnel syndrome, and headaches) to cause greater disability than the sum of individual disabilities. The Commission determined the ALJ erred in failing to properly consider medical testimony and evidence regarding the synergistic interaction of the employee's multiple conditions.

FINAL AWARD ALLOWING COMPENSATION

(Reversing Award and Decision of Administrative Law Judge)

**Injury No.:** 08-025433

**Employee:** Enrika Fox

**Employer:** Missouri Department of Corrections (Settled)

**Insurer:** Self-insured (Settled)

**Additional Party:** Treasurer of Missouri as Custodian of Second Injury Fund

This workers' compensation case is submitted to the Labor and Industrial Relations Commission (Commission) for review as provided by § 287.480 RSMo. We have reviewed the evidence, read the briefs, heard the parties' arguments, and considered the whole record. Pursuant to § 286.090 RSMo, the Commission reverses the award and decision of the administrative law judge.

Preliminaries

The parties asked the administrative law judge to resolve the sole issue of Second Injury Fund liability for permanent partial disability.

The administrative law judge denied the claim against the Second Injury Fund in full, finding the employee "failed to establish that the lumbar spine, cervical spine and right shoulder disabilities and the preexisting conditions of right knee patellofemoral syndrome, operated bilateral carpal tunnel syndrome, and headaches, combined synergistically to cause a greater disability than the simple sum of the individual disabilities".¹

The employee filed a timely application for review with the Commission alleging that the administrative law judge erred in determining that the work injury, in combination with preexisting medical conditions, did not combine synergistically to cause a greater disability than the simple sum of the individual disabilities. Specifically, the employee alleged that the administrative law judge erred in:

- Failing to determine the nature and extent of permanent disability of the employee's preexisting conditions;

- Ignoring Dr. Volarich's testimony and medical opinion;

- Ignoring the employee's testimony with respect to the issue of synergism;

- Ignoring uncontradicted testimony of unimpeached witnesses and not granting the employee all reasonable inferences;

- Not considering and applying testimony relating to pain caused by the employee's work injury and prior medical conditions.

For the reasons set forth below, we reverse the award and decision of the administrative law judge.

The Primary Injury

The parties stipulated that the employee sustained an accident arising out of and in the course of her employment on March 31, 2008, when she fell down a flight of stairs due to a broken handrail. On February 1, 2013, an administrative law judge approved a settlement of this claim against the employer, based on 12.5% of the body as a whole related to the lumbar spine, permanent partial disability of 4.5% of the body as a whole related to the cervical spine, and permanent partial disability of 5% of the right shoulder at the 232 week level. Neither party disputes nor challenges the administrative law judge's finding of permanent partial disability relating to the primary work injury, consistent with employee's settlement agreement.

Right Knee

The employee suffered an injury to her right knee in July 2004 as she experienced a "pop" in her right knee while getting out of a vehicle. The attending physician diagnosed this medical condition as patellofemoral syndrome and tendonitis. The employee testified she suffers achiness with weather changes and pain with walking. The residual effects of this medical condition cause her to walk with a limp or altered gait. The employee's work as a corrections officer involved "[w]alking up and down the wings, up and down stairs, checking on the offenders, conducting counts, [and] pretty much just walking the wings all day long." Because of her right knee condition, the employee walked carefully and more slowly than other guards did.

We find the employee's preexisting right knee condition constituted a hindrance or obstacle to employment because it had the potential to combine with disability from her primary injury to cause a greater degree of disability than would have resulted in the absence of the condition.

Dr. David Volarich evaluated the employee's preexisting industrial disability relating to patellofemoral syndrome as 20% permanent partial disability of the right lower extremity rated at the knee, stating that his rating accounts "for ongoing discomfort with prolonged weightbearing and any impact activities, stooping or squatting."

Right and Left Wrists

The employee developed bilateral carpal tunnel syndrome in 2003. She underwent open right carpal tunnel release in March 2004 and open left carpal tunnel release in December 2004. The employee's carpal tunnel syndrome has resulted in restrictions and limitations relating to activities that require sustained or heavy lifting.

The employee testified that prior to her 2008 injury she had problems gripping and using her hands when unlocking doors. She acknowledged these problems became less of an issue after a 2004 bilateral carpal tunnel release. Dr. Volarich evaluated the employee's preexisting carpal tunnel syndrome as 20% of each wrist.4

Headaches (Central Nervous System)

In 2006, the employee suffered paresthesias in the left face and experienced debilitating migraine headaches. Her attending physician diagnosed this condition as intractable vascular headaches and paresthesias and prescribed Topamax. Prior to the March 31, 2008, injury the employee missed work about two days a month due to migraine headaches. She testified that as a result of treatment for her migraine headaches in 2008 she "moved on to just the stress headaches, [and] it was a lot better, a lot more manageable."5 After about a year, the employee discontinued taking Topamax. She currently takes over-the-counter medication for stress related headaches about once a week. The employee testified that after her March 31, 2018, injury migraine headaches were no longer a problem.

Dr. Volarich assessed 5% preexisting permanent partial disability of the body as a whole relating to the employee's central nervous system, taking into consideration recurrent migraine headaches that require treatment.

Synergistic Interaction between Disabilities Related to Employee's Primary Injury and Preexisting Disabilities

#### Employee's Testimony

When asked about increased difficulties related to her multiple injuries, the employee explained that pain in one area sets off pain in other areas. Her pain level is enhanced and more difficult to control due to concurrent pain from multiple injuries. In particular, the employee believes her altered gait has made her low back more painful than it would otherwise be. She testified that her altered gait "affected ... the back and the neck and everything, because without walking straight, it threw everything off."6

The employee further summarized the impact of her cumulative disabilities on her ability to use proper body mechanics: "It's extremely affected. You know, everything runs together, so one thing is affected by the other. ... if the knee hurts, the back hurts, and if ... I have an off gait, then that affects the back and the neck and everything else."7 With respect to her mobility she stated, "I'm really slow. I have to take caution of what I do and how I do it."8

4 The administrative law judge noted that the employee settled a workers' compensation claim for 12.5% of each wrist in Injury No. 03-100593. Award, p. 5. As employee's counsel notes in his brief, employee's prior settlement does not constitute a stipulation or admission of specific disability. Seifner v. Treasurer of State-Custodian of the Second Injury Fund, 362 S.W.3d 59, 64 (Mo. App. 2012).

Addressing the synergistic effect of her disabilities, the employee concluded, "It's just hard to function ... when you have problems with everything. . ."9 She feels, as result of the combination of problems resulting from her back, knee, head, and tailbone, that she is unable to perform even the simplest of tasks.

**Dr. Volarich's Expert Opinion**

Dr. Volarich addressed the issue of synergistic/combination effects relating to the employee's primary injury and preexisting injuries in a January 9, 2017, Addendum following his March 1, 2010, report. Dr. Volarich described the human body as a kinetic chain where "every joint depends on the joint proximal to it and distal to it to accomplish movement... [therefore] injuries to the back or neck are going to have negative effects on movement of the arms and legs..."10

Dr. Volarich noted that the employee developed a slight limp after her 2004 right knee injury, which caused her low back and neck to become misaligned. "With loss of range of movement and abnormal gait she had to continue to be careful and move more slowly and deliberately."11 The employee's subsequent 2008 injury then caused an increase in her neck symptoms resulting in further loss of movement and pain, forcing her to move more slowly and be more deliberate with all of her activities. This compromised the employee's ability to perform lifting duties at work and intercept inmate altercations. Dr. Volarich noted that the employee was rarely asymptomatic. On some days, due to her combined disabilities the employee was simply not able to give her employer 100%. On other days, when "everything hurt" she was completely incapacitated from work. Dr. Volarich concluded, "The interplay between her injuries/medical conditions, made it more difficult to function efficiently at work and home."12

Dr. Volarich opined that the combination of the employee's disabilities created a substantially greater disability than the simple sum or total of each separate injury/illness and that therefore a loading factor should be added.

**Our Findings**

**Disability Relating to Primary Injury**

Noting that no party disputed this issue, we find the employee sustained permanent partial disability relating to her March 31, 2008, injury in the amount of 12.5% of the body as a whole related to the lumbar spine, permanent partial disability of 4.5% of the body as a whole related to the cervical spine, and permanent partial disability of 5% of the right shoulder at the 232-week level.

Right Knee

Based on the employee's credible testimony, especially regarding pain with walking and her altered gait, and Dr. Volarich's expert opinion we find the employee sustained a preexisting disability in the amount of 20% of her right lower extremity rated at the knee.13

Right and Left Wrists

We find the employee had preexisting permanent partial disability relating to her right and left wrists in the amount of 12.5% of each wrist.

Headaches (Central Nervous System)

Based on the employee's testimony that after appropriate medical treatment her migraine headaches had ceased to be a problem around the time of her 2008 injury, we find that the employee's preexisting disability relating to the central nervous system was not of such seriousness as to constitute a hindrance or obstacle to employment or to obtaining reemployment if the employee becomes unemployed. We assign no preexisting permanent partial disability relating to the employee's central nervous system.

Synergistic Interaction between Disabilities Related to Employee's Primary Injury and Preexisting Disabilities

We find, as a factual matter, that the employee has sustained greater permanent partial disability than resulted from the primary injury alone due to synergistic interaction between disability to her lumbar spine and cervical spine in combination with her preexisting right knee disability. In so finding, we rely on Dr. Volarich's expert medical opinion on the issue of "synergy". We also rely on the employee's credible testimony regarding increased difficulties related to her multiple disabilities, largely due to her altered gait.

Dr. Volarich makes the case for a synergistic relationship between the employee's disabilities across the board. Although Dr. Volarich's credible testimony convinces us there is more likely than not some degree of synergy associated with the employee's right shoulder disability attributable to the primary injury and her preexisting bilateral carpal tunnel syndrome, we find insufficient evidence to enable us to quantify the degree of synergy attributable to these conditions.

As we have found, the employee had no preexisting permanent partial disability relating to her central nervous system that constituted a hindrance or obstacle to employment or reemployment.

13 We note the absence of any medical opinions regarding the employee's preexisting disability other than that of Dr. Volarich.

We calculate the Second Injury Fund's liability for permanent partial disability attributable to synergistic interaction between disability relating to the employee's lumbar and cervical spine attributable to the employee's primary injury and the employee's preexisting right knee disability based on a loading factor of 10%.

Law

Section 287.220 RSMo creates the Second Injury Fund. Section 287.220.2 applies to injuries occurring prior to January 1, 2014, and provides when and what compensation will be paid by the Fund in "all cases of permanent disability where there has been previous disability." *Id.* This section provides, in pertinent part:

> 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, ... 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 the 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 (emphasis added).

Missouri courts have established the following test for determining whether a preexisting disability constitutes a "hindrance or obstacle to employment":

> [T]he proper focus of the inquiry is not on the extent to which the condition has caused difficulty in the past; it is on the potential that the condition may combine with a work-related injury in the future so as to cause a

greater degree of disability than would have resulted in the absence of the condition.

Knisley v. Charleswood Corp., 211 S.W.3d 629, 637 (Mo. App. 2007) (citation omitted).

To find liability of the Second Injury Fund for permanent partial disability benefits,

[T]he claimant must establish that the present compensable injury and his preexisting permanent partial disability combined to cause a greater degree of disability than the simple sum of the disabilities viewed independently. This is referred to as the "synergistic effect." If a claimant establishes that the two disabilities combined result in a greater disability than that which would have occurred from the last injury alone, then the Fund is liable for the degree of the combined disability that exceeds the numerical sum of the preexisting disabilities and the disability from the last injury, or the "synergistic effect" of the combined disabilities. In other words, the Fund is liable only for the amount attributable to the synergistic combination. Thus, the failure to prove a synergistic combination between the primary injury and a preexisting disability is proper grounds for denying Fund liability.

Winingear v. Treasurer of State, 474 S.W.3d 203, 207-08 (Mo. App. 2015). See also Pierson v. Treasurer of Mo. As Custodian of the Second Injury Fund, 126 S.W.3d 386 (Mo. 2004) and Calvert v. Treasurer of State, 417 S.W. 3d 299 (Mo. App. 2013).

In order to prove a claim for permanent partial disability against the Second Injury Fund, an employee must demonstrate that her preexisting disability combines with a subsequent compensable injury "so that the degree or percentage of disability caused by the combined disabilities is substantially greater than that which would have resulted from the last injury considered alone and of itself (emphasis added)."14

Simply put, the fund is liable only for the degree of the combined disability that exceeds the numerical sum of the pre-existing disabilities and the disability from the last injury. This excess for which the fund is liable is referred to as the synergistic effect of the combined disabilities (emphasis added).

Treasurer of Missouri-Custodian of Second Injury Fund v. Witte, 414 S.W.3d 455,467. (Mo. 2015).

In Witte, the Supreme Court held that 287.220.1 imposes no numerical threshold for permanent partial disability from the employee's last injury. Id. at 467.

Witte further instructs that, for purposes of triggering Fund liability based on preexisting disability, 287.220.1 does not allow combination of a major extremity disability with a

14 Section 287.220.2 RSMo.

Employee: Enrika Fox

- 8 -

body as a whole disability but instead "expresses the minimum thresholds only in terms of a singular injury to either the body as a whole or a major extremity". *Id.* 465.

However, once the threshold of either fifty weeks of compensation for a body as a whole injury or fifteen percent permanent partial disability of a major extremity is met, pursuant to the statute's plain and ordinary meaning "all preexisting injuries, without the threshold limitation, are to be considered" in the calculation of Fund liability. *Id.* 467.

**Conclusions of Law**

As we have found, permanent partial disability in the amount of 17% of the body as a whole related to the cervical and lumbar spine, attributable to the employee's March 31, 2008, work injury, combined synergistically with preexisting disability consisting of 20% of the employee's right lower extremity rated at the 160-week level, to result in disability that exceeds the numerical sum of the total disabilities.

The employee's preexisting disability of 20% of her right lower extremity meets the 15% permanent partial disability of a major extremity numerical required to trigger Second Injury Fund liability, for permanent partial disability pursuant to 287.220.

The Second Injury Fund argues that the employee had no preexisting right knee disability because the employee acknowledged that prior to her 2008 injury she worked full duty and that her right knee condition, despite flare-ups, was not constantly an issue. The Second Injury Fund's counsel reasons that, based on the foregoing testimony, the employee's right knee disability did not constitute a "hindrance or obstacle to employment", as required by 287.220. Pursuant to the test established in *Kinsley, supra*, the employee's testimony minimizing the effect of her knee condition prior to her 2008 injury does not preclude our finding that this condition constituted a hindrance or obstacle to employment. We find Second Injury Fund's argument on this point unpersuasive.

Based on the employee's credible testimony and Dr. Volarich's expert opinion, we have found the employee met her burden of establishing a synergistic effect between permanent partial disability resultant from her primary injury to the cervical and lumbar spine and preexisting permanent partial disability to the right knee.

Missouri courts have held that the testimony of a claimant or other lay witness "can constitute substantial evidence of the nature, cause, and extent of the disability when the facts fall within the realm of lay understanding." *Goleman v. MCI Transporters*, 844 S.W. 2d 463, 466 (Mo. App. 1993) (overruled on other grounds, *Hampton v. Big Boy Steel Erection*, 121 S.W.3d 220 (Mo. 2003); citing *Griggs v. A. B. Chance Co.*, 503 S.W. 2d 697 at 704 (Mo. App. 1973).

As a factual matter, we have quantified the Second Injury Fund's liability for permanent partial disability attributable to the synergistic interaction between disability to the employee's lumbar and cervical spine resultant from the primary injury and preexisting disability to her right knee based on a loading factor of 10%.

ISSUES DECIDED

The evidentiary hearing in this case was held on June 8, 2017, in Jefferson City, Missouri. The parties requested leave to file post-hearing briefs, which leave was granted, and the case was submitted on August 8, 2017. The hearing was held to determine the liability, if any, of Second Injury fund for permanent partial disability.

STIPULATIONS

For purposes of this hearing, the parties entered into a stipulation agreement as follows:

  1. The Division of Workers' Compensation has jurisdiction over this case;
  2. Venue for the hearing is proper in Audrain County and adjoining counties; the parties agree to holding the hearing in Cole County;
  3. The claim is not time-barred by Section 287.430, RSMo;
  4. The notice requirement of Section 287.420 is not a bar to Claimant's Claim for Compensation;
  5. Both Employer and Employee were covered under the Missouri Workers' Compensation Law at all relevant times;
  6. That the average weekly wage was $\ 567.72 with a compensation rate of $\ 378.48 for permanent partial disability benefits;
  1. That Employee sustained an accident arising out of and in the course of her employment with the Missouri Department of Corrections on March 31, 2008 in Audrain County, Missouri.

EVIDENCE

The evidence consisted of the testimony of Claimant, Enrika Fox, as well as the narrative reports of Dr. David Volarich, the deposition and narrative reports of Dr. Craig Aubuchon, Stipulations of settlements and medical records.

DISCUSSION

Claimant was born August 8, 1976. Claimant has been employed with the Missouri Department of Corrections since 1998. As stipulated, Claimant sustained an accident arising out of and in the course of her employment in Audrain County, Missouri on March 31, 2008. The accident occurred as Claimant was walking down a flight of stairs as part of her duty as a corrections officer. Claimant was holding onto the handrail, when the handrail broke, causing Claimant to fall. Claimant injured her low back, neck and right shoulder. A stipulation for compromise settlement with Employer was approved on February 1, 2013, by Administrative Law Judge David Zerrer. The settlement was based upon a permanent partial disability of 12.5 % of the body as a whole related to the lumbar spine, a permanent partial disability of 4.5 % of the body as a whole related to the cervical spine, and a permanent partial disability of 5 % of the right shoulder.

The sole issue to be decided is the liability, if any, of the Second Injury fund for permanent partial disability benefits.

Regarding Claimant's claim against the Second Injury Fund for permanent partial disability, Claimant testified about a prior right knee condition, bilateral carpal tunnel syndrome, and recurring headaches.

Claimant began complaining of right knee pain in July 2004 when she felt a pop in her right knee when getting out of a vehicle. She testified that she was on light duty for a few weeks,

Issued by DIVISION OF WORKERS' COMPENSATION

**Employee:** Enrika Fox

**Injury No. 08-025433**

but eventually returned to full duty. There was no surgery. Claimant continued to perform her job which, as detailed above, required prolonged walking and standing on concrete. Dr. Volarich opined that Claimant sustained a permanent partial disability of 20% of the right knee due to patellofemoral syndrome.

Claimant developed bilateral carpal tunnel syndrome in 2003. She underwent open right carpal tunnel release in March 2004 and open left carpal tunnel release in December 2004. Claimant settled her workers' compensation claim (Injury No. 03-100593) for 12.5% permanent partial disability of each wrist. Dr. Volarich opined that Claimant sustained a permanent partial disability of 20% of each wrist due to bilateral carpal tunnel syndrome.

Sometime around June 29, 2006, Claimant began experiencing recurring headaches. She was treated with Topamax, and, even after stopping the medication, she has not experienced a migraine since 2008. Claimant testified that she gets an occasional stress headache, but does not experience migraines anymore and her ability to perform her job duties was not affected by headaches. Dr. Volarich opined that Claimant sustained a permanent partial disability of 5% of the body as a whole due to migraines.

To find liability of the Second Injury Fund for permanent partial disability benefits, Claimant must establish the last compensable injury - to her low back, neck and right shoulder - and the preexisting permanent partial disabilities combine to cause a greater degree of disability than the simple sum of disabilities viewed independently. *Winingear v. Treasurer*, 474 S.W.3d 203 (Mo. App. W.D. 2015). The failure to prove a "synergistic effect" between the last compensable injury and a preexisting disability is grounds for denying Fund liability. *Winingear* at 208.

Claimant attempted to establish synergy through her testimony at hearing and the opinion reports of Dr. Volarich. Dr. Volarich provided a January 9, 2017 addendum to his earlier reports to attempt to explain synergistic effects. His conclusion is illustrative:

During a typical workday some body part hurt her, usually neck, low back, or right knee in particular. It was rare to be completely asymptomatic on a given day. There were days

Issued by DIVISION OF WORKERS' COMPENSATION

**Employee:** Enrika Fox

**Injury No. 08-025433**

When everything hurt which caused her to miss work, particularly with headaches, or not being able to give her employer 100% which in my opinion is the best example of synergistic effect. (Exhibit 24, page 3.)

Dr. Volarich does not explain how Claimant's injuries combined to create a greater degree of disability, but simply states that different body parts hurt on different days. There is no combination evidence whatsoever.

FINDINGS OF FACT AND RULINGS OF LAW

In addition to those facts and legal conclusions to which the parties stipulated, I find the following:

  1. Immediately prior to her March 31, 2008 work accident, Claimant was working as a corrections officer with the preexisting conditions of right knee patellofemoral syndrome, operated bilateral carpal tunnel syndrome, and headaches.
  1. The March 31, 2008 accident occurred as Claimant was walking down a flight of stairs as part of her duty as a corrections officer. Claimant was holding onto the handrail, when the handrail broke, causing Claimant to fall.
  1. As a result of the March 31, 2008 accident, Claimant sustained permanent and disabling injuries to her low back, neck and right shoulder.
  1. As a result of the March 31, 2008 accident, Claimant sustained a permanent partial disability of 12.5% of the body as a whole related to the lumbar spine, a permanent partial disability of 4.5% of the body as a whole related to the cervical spine, and a permanent partial disability of 5% of the right shoulder.
  1. Claimant failed to establish that the lumbar spine, cervical spine and right shoulder disabilities and the preexisting conditions of right knee patellofemoral syndrome, operated bilateral carpal tunnel syndrome, and headaches, combined

Hood v. City of Kansas City, Missouri(2018)

January 10, 2018#14-018909

affirmed

The Labor and Industrial Relations Commission affirmed the administrative law judge's award of permanent total disability benefits to James Hood against the Second Injury Fund based on the combination of his primary injury from February 21, 2014, and preexisting disabling conditions from multiple prior work-related injuries. The Commission found that the 2014 amendments to § 287.220.3 RSMo did not apply because some preexisting injuries predated January 1, 2014, and the claim satisfied the statutory requirements under § 287.220.2 RSMo.
