OPINION
KLEINFELD, Circuit Judge:
We address admissibility under Daubert1 of medical testimony.
I. Facts
Marylou Primiano has suffered a miserable ordeal since she had elbow surgery. The question raised by her litigation2 is
Ms. Primiano, an active 36-year-old woman, fell in her kitchen and broke her elbow. The injury, serious for anyone, was especially serious for her, because she has had rheumatoid arthritis for years. Unlike osteoarthritis, a degenerative process of wear and tear on the joints, rheumatoid arthritis is a chronic inflammatory disease of the connective tissue in the joints.3 Her physician, Robert J. Tait, M.D., performed surgery April 18, 2000, two days after her fall. He replaced her elbow joint with a device made by the defendant, Howmedica, consisting of titanium pieces to replace the bone and polyethylene components to prevent the metal from rubbing against metal.
Two thirds of the way through surgery, Dr. Tait discovered that Howmedica had made a mistake in the packing and shipping, so even though he was replacing Ms. Primiano‘s right elbow, the humeral component (the humerus is the arm bone
But by July, Ms. Primiano‘s elbow squeaked, and by December, Dr. Tait could hear the metal-on-metal contact, which he confirmed in an x-ray. In February, Dr. Tait performed a second surgery addressing the evident failure of the implant and risk of metallosis (a destructive immune response of the body to flecks of metal shaved off by metal-on-metal contact), replacing the humeral component with a longer one. He used Howmedica‘s left arm humeral component again, though the long instead of the standard, to avoid having to redrill the remaining bone. He observed massive metallosis and “severe polyethylene wear” on the bearing surrounding the pin. Again, the surgery appeared to go fine. But the next month, Ms. Primiano was having trouble controlling her arm and the joint had a “cracking” sound. She obtained a second opinion from an orthopedic surgeon who concluded that the components appeared “to be adequately fixed and in good position.” But in June her problems with the joint had not gone away, so she consulted a third orthopedic surgeon, who recommended a third surgery. In July this surgeon replaced her Howmedica device with one from its competitor, Zimmer. That surgeon performed a fourth surgery the next April to correct loosening. A pin backed out of position, so she needed yet another surgery, her fifth, in September.
Primiano sued Howmedica, Dr. Tait, and others in state court for negligence, strict liability, breach of warranty, and
In the summary judgment papers, Howmedica‘s experts, an orthopedic surgeon and a chemist, provided opinions that the polyethylene was as it should be, and the rapid failure of the prosthesis and excessive wear on the polyethylene components resulted from “malalignment of the prosthesis” along with increased risk of complication because of Ms. Primiano‘s rheumatoid arhtritis and her age. The product literature distributed to physicians said that the prosthesis would not restore function to the level expected with normal healthy bone, and was vulnerable to excessive loading from activity. Evidently, younger patients such as Ms. Primiano may do worse because they are more active. The manufacturer‘s literature says “[w]hile the expected life of the total elbow replacement components is difficult to estimate, it is finite.”
Primiano‘s expert witness, Arnold-Peter Weiss, M.D., declared that the polyethylene bushing had worn through in less than eight months, “not a usual or expected circumstance.” Though finite, the typical lifespan of elbow prostheses “far exceeds” how long this one lasted. Dr. Weiss testified in his deposition that although wear starts immediately, elbow prostheses last as long as ten or fifteen years, even twenty, and the earliest he had seen them wear out was around five to eight years, varying with the patient‘s activity level. Though misalignment could cause excessive wear, he had looked at the x-rays and found no significant misalignment. Nor would ordinary daily activity produce such extraordinarily rapid wear. Nor could he find technically inappropriate use of the prosthesis by Dr. Tait. His opinion was that the extraordinarily rapid wear was caused by abrasive wear and generation of debris from movement of the titanium against the
The district court granted defendants’ motion to exclude Dr. Weiss‘s testimony as not meeting the Daubert standard and granted summary judgment. The court concluded that Dr. Weiss‘s testimony would not be helpful to the jury. The judge reasoned: “Well, I mean it‘s like res ipsa loquitur, the elbow failed. Now, why did it fail? Maybe it was malpractice, maybe it was Dr. Tait.” The evidence of rapid wear “doesn‘t make it defective.” “I think [Dr. Tait‘s] opinion is weakened by the fact that he didn‘t see the plaintiff. He didn‘t examine her. He didn‘t talk to her.” “[T]here‘s no peer review . . . no publication . . . there‘s got to be an objective source that he relies on.” The court rejected plaintiff‘s argument, that testimony that the premature failure was not attributable to overuse, medical malpractice, “her physiology,” or other factors external to the device, would assist the jury.
II. Analysis
We review summary judgment de novo.5 We review rulings on the admissibility of expert testimony under
[1] Ms. Primiano‘s burden was to establish a defect in the manufacture of the artificial elbow. In Nevada, “those products are defective which are dangerous because they fail to perform in the manner reasonably to be expected in light of their nature and intended function.”10 A plaintiff need not “produce direct evidence of a specific product defect [or] negate any alternative causes of the accident.”11 An “unexpected, dangerous malfunction” suffices.12

If scientific, technical, or other specialized knowledge will assist the trier of fact to understand the evidence or to determine a fact in issue, a witness qualified as an expert by knowledge, skill, experience, training, or education, may testify thereto in the form of an opinion or otherwise, if (1) the testimony is based upon sufficient facts or data, (2) the testimony is the product of reliable principles and
methods, and (3) the witness has applied the principles and methods reliably to the facts of the case.13
Though Daubert is sometimes loosely spoken of as though it established the court‘s “gatekeeping” function, that is not quite right. Trial courts have always had a gatekeeping function for opinion evidence. Daubert held that
[3] The requirement that the opinion testimony “assist the trier of fact” “goes primarily to relevance.”16 For scientific opinion, the court must assess the reasoning or methodology, using as appropriate such criteria as testability, publication in peer reviewed literature, and general acceptance, but the inquiry is a flexible one.17 Shaky but admissible evidence is to be attacked by cross examination, contrary evidence, and attention to the burden of proof, not exclusion.18 In sum, the trial court must assure that the expert testimony “both rests on a reliable foundation and is relevant to the task at hand.”19 Kumho Tire Co. v. Carmichael holds that the Daubert framework applies not only to scientific testimony but to all expert testimony.20 It emphasizes, though, that the “test of reliability is ‘flexible’ and Daubert‘s list of specific factors neither nec-
