On January 7, 2012, employee rolled his left ankle walking on uneven concrete while working for employer. Dr. Eddie Runde diagnosed a sprain with tears of the peroneal tendons, and employee settled his claim against the employer/insurer based upon an approximate 3\% permanent partial disability of the left ankle. Employee seeks enhanced permanent partial disability benefits from the Second Injury Fund based on an alleged synergistic interaction between the effects of the primary left ankle injury and preexisting permanent partially disabling conditions affecting his groin, left ankle, and right knee. The administrative law judge found that employee suffered a preexisting 10\% permanent partial disability of the body as a whole referable to the groin, ${ }^{1}$ a preexisting 38 % permanent partial disability of the left ankle, ${ }^{2}$ and a preexisting 15 % permanent partial disability for the right knee; ${ }^{3}$ she also found that employee suffered a 3 % permanent partial disability of the left ankle as a result of the primary injury, but denied the claim against the Second Injury Fund on a finding that employee failed to present any credible or convincing evidence of a synergistic interaction between the effects of the primary injury and employee's preexisting conditions of ill-being.

[^0]: ${ }^{1}$ In 2011 a patient grabbed employee's groin area during a scuffle. Dr. Runde diagnosed a bilateral testicle and scrotum injury; Dr. Harmon later diagnosed orchialgia, orchitis, and epididymitis. Employee settled his claim against the employer/insurer based upon an approximate 10\% permanent partial disability of the body as a whole, plus 3.5 weeks of disfigurement.
${ }^{2}$ In 2008 employee suffered a torn anterior talofibular ligament while playing basketball with patients. He underwent three surgeries and settled his claim against the employer/insurer based upon an approximate 38\% permanent partial disability of the left ankle.
${ }^{3}$ In 2002 employee suffered a right knee meniscal tear injury stepping off a piece of equipment. He underwent an arthroscopic chondroplasty and medial plica synovectomy, and settled his claim against a prior employer based upon an approximate 15 % permanent partial disability of the right knee.

Employee filed a brief wherein he fails to identify any evidence of synergy, and instead cites the record for evidence of the complaints and symptoms referable to each of his injuries in isolation. We note that, at the hearing before the administrative law judge, employee's attorney did not ask him whether he experiences any enhanced disability from the combination of his preexisting conditions of ill-being with the effects of the work injury. We note also that the May 11, 2011, report from Dr. David Volarich does not (for obvious reasons) contain an opinion from the doctor regarding the primary injury of January 7, 2012, or identify any synergistic interaction between that injury and employee's preexisting conditions of ill-being. Our review of the medical treatment records in evidence does not readily disclose any findings indicative of synergy, and we will not parse them for such findings especially where employee does not, in his brief, provide us with any citations to evidence of synergy.
Typically, the synergistic interaction between bilateral extremity injuries (e.g. a left ankle and a right knee) would be well within the realm of lay understanding, but here employee has failed to provide any evidence of synergy, lay or expert. As a result, we must affirm the administrative law judge's award denying benefits from the Second Injury Fund, because an award of compensation cannot rest upon mere speculation or surmise. Griggs v. A. B. Chance Co., 503 S.W.2d 697, 703 (Mo. App. 1973).
