Even pursuant to the applicable law, Dr. Shelby Kopp's opinion persuades this Commission to find that employee failed to meet his burden to show medical causation. We find persuasive that employee's bilateral avascular necrosis in his hips caused his medical condition; the incident of missing a step was simply a triggering or precipitating factor.
We note that both Dr. Robert Pierron and Dr. Michael Burns agreed that there was a possibility of a subchondral fracture. However, Dr. Burns never saw a fracture line and Dr. Pierron never mentioned the possibility of a fracture after reviewing the MRI taken on September 8, 2005. Dr. Pierron's impression after reviewing the new MRI was, "Findings compatible with bilateral avascular necrosis of the hips. The right side is affected to a greater extent than the left which would correspond with the patient's clinical presentation." Tr., p. 144.
Injury No.: 05-041432
Employee: Michael Thomson

We do not find persuasive Dr. David Volarich's or Dr. Robert Sciortino's opinions regarding medical causation. After employee's initial visit with Dr. Sciortino, Dr. Sciortino never again mentioned the possibility of a fracture. Instead, Dr. Sciortino focused on employee's avascular necrosis.
Therefore, employee failed to meet his burden regarding medical causation.
**Comments by the Administrative Law Judge**
We disavow particular comments by the administrative law judge in this matter regarding medical causation, namely, that:
- "Falling off a single rung of a ladder, hardly supports Dr. Volarich's assertion of an 'impaction injury.'" Award, p. 12.
- "Again, employee's minor fall is not a reasonable supposition to impose liability of surgical treatment of a chronic condition." Award, p. 12.
The administrative law judge's comments regarding medical causation were not appropriate as a basis for determining a lack of medical causation. "[T]he question of causation is one for medical testimony, without which a finding for claimant would be based upon mere conjecture and speculation and not on substantial evidence." *Van Winkle v. Lewellens Prof'l Cleaning, Inc.*, 258 S.W.3d 889, 897 (Mo. App. 2008) (quoting *Elliott v. Kan. City School Dist.*, 71 S.W.3d 652, 658 (Mo. App. 2002)). The *Van Winkle* court continued, "[a]ccordingly, where expert medical testimony is presented, 'logic and common sense,' or an [administrative law judge's] personal views of what is 'unnatural,' cannot provide a sufficient basis to decide the causation question, at least where the [administrative law judge] fails to account for the relevant medical testimony." *Van Winkle*, 258 S.W.3d at 897-98.
As opposed to relying on the administrative law judge's statements regarding medical causation, we rely on the statements and opinions of the medical experts in this matter, as stated above.
Because we do not find that employee established medical causation in this matter, we must deny the claim. All other issues are moot.
**Decision**
We affirm and adopt the award of the administrative law judge as supplemented herein.
The award and decision of Administrative Law Judge Joseph P. Keaveny, issued May 31, 2018, is attached and incorporated herein to the extent not inconsistent with this supplemental decision.
