Plaintiff’s Professional’s “Intestine” Feeling Not Sufficient to Face up to Rule 702 or Abstract Judgment


Hearken to your intestine.  Comply with your instincts.  Belief your instinct.  Nice recommendation in lots of conditions.  Like deciding whether or not to purchase skinny denims or whether or not to purchase your eternally residence.  Or, when issues appear “off” or really feel “harmful.”  Or, when your physique is making an attempt to inform you one thing about your well being.  These are all instances to research your emotions a few scenario and permit your “intestine” or “sense” to be your information (or a minimum of a again seat driver you don’t ignore).  A basic sense, feeling, or impression, nevertheless, doesn’t get the job finished if you end up the medical causation skilled in a posh medical machine case.  Because the court docket in Hobus v. Howmedica Osteonics Company, 2023 WL 6850144 (D. Ore. Oct. 17, 2023) advised plaintiff when it dismissed his case. 

Plaintiff suffered from again issues almost his entire life that have been exacerbated by a automotive accident in 2014 that led to spinal fusion surgical procedure in 2016 throughout which his surgeon selected to implant an expandable interbody fusion cage machine manufactured by the defendant.  Plaintiff alleged that the collapse of the cage induced him to need to endure revision surgical procedure and induced him to undergo persistent ache.  Plaintiff submitted three skilled studies – a medical causation report from his implanting surgeon, a design defect report from a biomedical engineer, and a damages report.  Defendant moved to exclude all three and for abstract judgment.  The movement on the damages skilled was denied which was of no consequence as a result of the court docket excluded the medical causation skilled in his entirety and the majority of the engineering opinion. 

As a result of plaintiff’s medical causation skilled was his treating surgeon, the court docket took its time detailing the surgeon’s opinions within the treating data.  Opinions akin to:  plaintiff’s MRI reveals no twine compression or nerve root impingement and “there may be nothing there to account for his [pain];” or primarily based on additional MRIs the surgeon noticed “no apparent issues there or clarification as to why [plaintiff] was having signs.”  Most significantly, when machine failure was recognized, his surgeon famous that plaintiff had achieved a “strong fusion” and subsequently the failure was “of questionable significance,” there was nonetheless no neural impingement, and there was a “low” probability that revision surgical procedure would alleviate plaintiff’s ache.  Id. at *2-3. 

Flash ahead to changing into plaintiff’s skilled, and the surgeon’s new opinion was that the collapse of the cage was an “vital contributing issue” to and “main trigger” of plaintiff’s accidents.  Id. at *5.  Plaintiff’s skilled report supplied “little element” concerning how he reached this new conclusion.  And when requested at deposition what his methodology was, one of the best he may say was “it’s simply my sense.”  His “intestine says he may need finished higher.”  Confirming he used no methodology, he stated “I simply have my instincts as a clinician.”  Id. at *5-6.  So, it was no stretch for the court docket to conclude that plaintiff’s skilled “utilized no typically accepted methodology in arriving at his medical conclusions.”  Id. at *6.  Medical expertise generally is a foundation for dependable skilled testimony, however solely the place the clinician has “intensive expertise” with the difficulty on which he’s opining.  Right here, plaintiff’s skilled had just one affected person who skilled a cage collapse – plaintiff.  Id.  The court docket discovered it “tough” to name that enough expertise on which to base his opinion.                

Plaintiff additionally tried to argue that his surgeon relied on his personal medical data to achieve his conclusions.  As identified above, that’s a stretch too.  However extra importantly, the court docket acknowledged the final precept that

Though medical data could, in some circumstances, help a clinician’s general conclusion, they don’t independently confirm the methodology that the clinician used. That’s, whereas a medical file will be the foundation of an skilled’s findings, it affords no clarification for the validity of the skilled’s strategies.

Id.  At most, the surgeon’s data demonstrated a “constant uncertainty” as as to whether the cage collapse was a doable reason for plaintiff’s accidents. 

Lastly, plaintiff’s skilled failed to handle “the quite a few doable components inflicting plaintiff’s ache.”  Id. at *8.  He deemed the cage collapse was a major causative issue of plaintiff’s ache with out contemplating the affect of different components affecting ache.  “[A]n skilled opinion that wholly fails to think about various causes can’t be a reliably primarily based opinion.”  Id.  Taken collectively, the court docket had greater than sufficient causes to exclude plaintiff’s medical causation skilled.

Plaintiff’s design defect skilled didn’t fare a lot better.  She concluded that to be secure, defendant’s cage wanted to face up to a power of two,000 N.  However past that, the court docket couldn’t conclude that she reliably utilized that opinion to the info of the case.  She checked out six scientific failure studies however performed no inquiry as to why the units failed in these circumstances – she had no data on these sufferers’ ages, weights, exercise ranges, and many others. to know the quantity of power positioned on these units.  She “assumed” these failures have been resulting from a design defect.  Do assumptions ever actually work out in any context?  Id. at *11.

Plaintiff’s skilled didn’t take a look at the mannequin of cage that was utilized in plaintiff’s surgical procedure.  In different phrases, the skilled didn’t decide whether or not the machine may stand up to 2,000 N earlier than opining it was faulty for failing to fulfill that customary.  The corporate testing that the skilled did depend on was about “breakage” not machine collapse and the skilled supplied no clarification for her “leap” from breakage to break down making her opinion “wholly speculative.”  Id. at *12.  Not solely did the skilled not take a look at the mannequin, she didn’t take a look at the precise machine utilized in plaintiff’s surgical procedure.  She may have however determined to not due to the associated fee.  Failing to take this step that might have supplied an goal foundation for her opinion, “deeply undermines the reliability” of her conclusion.  Id.  

The design skilled additionally supplied an opinion on possible various design.  She supplied two—the primary was not an alternate design and the second was not possible.  First, she instructed various designs that weren’t expandable.  However that may be a vital design function of defendant’s product that gives utility not obtainable in static cages.  Id. at *14.  So, as we now have identified in different circumstances a unique product is just a unique product, not an alternate design of the product at challenge.  Second, plaintiff’s skilled testified about methods the expandable cage could possibly be improved however had not carried out any evaluation to find out if any of her concepts have been possible.  So, she couldn’t testify on various design.

Lastly, maybe realizing the place issues have been headed along with his medical causation skilled, plaintiff tried to sneak in medical causation by his biomedical engineer.  However rendering opinions as to the precise reason for plaintiff’s accidents goes properly past her engineering experience.  Her engineering expertise and coaching could enable her to make basic findings concerning what accidents could happen from a cage collapse, however providing opinions that join the cage collapse to plaintiff’s particular accidents crosses into medical causation on which this skilled was not certified to opine.

Ultimately, it was the exclusion of plaintiff’s medical causation skilled that led the court docket of award abstract judgment for the defendant.  Oregon regulation requires skilled testimony the place causation includes complicated medical questions. With out a causation skilled, plaintiff couldn’t meet his burden of proof which is only a tad extra onerous than intestine emotions and fundamental instincts.
