NIX, Chief Justice.
The issue in this case is whether a plaintiff proceeding on the strict liability theory of product malfunction will be precluded from having a jury decide the case if the manufacturer of the product introduces evidence of the negligence of another party as the cause of the malfunction. Contrary to the Superior Court, we conclude not.
The facts are that on May 1, 1977, Price Rogers entered Lankenau Hospital for the treatment of a broken leg. Dr. John J. Dowling, Lankenau’s Chief of Orthopedic Surgery, and Dr. Lawrence Naame, a third year resident on rotation from Thomas Jefferson University Hospital, treated Mr. Rogers. Dr. Dowling recommended surgery which was scheduled for the following day. Dr. Dowling ordered the application of a plaster splint pending the surgery. Unlike a cast, a splint covers only part of an injured limb. Its application immobilizes the injured limb so as to prevent complications from, for example, the broken bone interfering with circulation.
Dr. Naame left the holding room to prepare the splint for application. This required arranging several layers of cotton insulation to be placed under a plaster wrapping product which itself required dipping in tepid or lukewarm water [179]*179and arranging or “reversing” in several layers. When dipped in water, the product reacted exothermically, as it should have.
After preparing the splint in this fashion, Dr. Naame returned to the holding room. There Dr. Dowling held up the injured leg while both physicians applied the insulation and the plaster wrap so as to form a splint on its underside. Mr. Rogers complained of a sensation of warmth. Dr. Dowling assured him this was to be expected. When the splint began to harden, Dr. Dowling lowered the leg and left the room to arrange for Mr. Rogers’ admission into the hospital. Mr. Rogers complained to his wife, who was in the holding room, of a burning sensation. She applied ice to the uppermost part of the splint, at the top of her husband’s thigh, and left the room to locate Dr. Dowling. She found him, informed him of her husband’s complaints, and accompanied him back to the room. At that point, Mr. Rogers simply requested anesthesia should future painful procedures be required.
Prior to surgery the next morning, Dr. Dowling removed the splint. He discovered second and third degree burns on the back of the leg. Although able to undergo the open reduction surgery, Mr. Rogers experienced a longer, more painful recuperative period, requiring a skin graft, therapy, and home nursing for several months.
Mr. and Mrs. Rogers filed a complaint in trespass against Johnson & Johnson, manufacturer of the plaster splint, Lankenau Hospital and Thomas Jefferson University Hospital. The complaint alleged negligence and strict liability against Johnson & Johnson and Lankenau Hospital. It alleged negligence against Thomas Jefferson University Hospital. Johnson & Johnson answered by denying liability and cross-claimed against the hospitals.
At trial, the Rogers’ case against Johnson & Johnson consisted of evidence of malfunction, failure to warn, and [180]*180negligence.1 They also presented expert testimony eliminating medical malpractice as the cause of burns.2
Thomas Jefferson University Hospital likewise adduced evidence eliminating medical malpractice as the cause of the plaster’s having burned Mr. Rogers. On the other hand, Johnson & Johnson introduced expert testimony indicating that the medical malpractice of the doctors had caused the splint to overheat and to burn Mr. Rogers. The trial court denied all motions for nonsuits and for directed verdicts save that of Lankenau Hospital with respect to its ostensible agency relationship with Dr. Dowling.
At the close of the evidence the jury was given a verdict form which directed it to decide first whether the Johnson & Johnson plaster was defective as a result of malfunction, second whether it was defective as a result of failure to warn the user, and if the answer to either of these questions was affirmative, to decide thirdly whether the defect was a substantial factor in bringing about the plaintiffs’ harm. The jury returned a verdict against Johnson & Johnson only on the malfunction theory by answering affirmatively to that question and to the question of the malfunction’s having caused the plaintiffs’ harm. The jury [181]*181did not answer or consider the question regarding a failure to warn. Per the trial court’s instructions, once it answered affirmatively as to malfunction and causation, the jury did not reach remaining questions on the verdict form dealing with the negligence of any defendant.
Johnson & Johnson appealed the judgment following the denial of its post-trial motions. The Superior Court reversed and granted a new trial. The Superior Court concluded that because Johnson & Johnson had adduced sufficient evidence of negligence on the part of Dr. Naame to submit that issue to a jury, the plaintiffs had not sustained their burden of proof in eliminating reasonable, secondary causes for the malfunction. The Superior Court reasoned:
In a case where there is sufficient evidence of negligent human intervention as a cause of the malfunction of a product to enable a trial court to conclude that an independent theory as to the cause of the plaintiff’s injuries based on that negligence merits submission to the jury, the plaintiff has not sustained its burden of eliminating other reasonable secondary causes for the malfunction. Thus, the malfunction theory strict liability claim of such a plaintiff must fail in that he has failed to present a jury question as to the existence of a defect which is an essential element of his cause of action.

Although the Superior Court has considered the malfunction theory of strict liability, see Thompson v. Anthony Crane Rental Inc., 325 Pa.Super. 386, 473 A.2d 120 (1984); MacDougall v. Ford Motor Company, 214 Pa.Super. 384, 257 A.2d 676 (1969), this Court has never fully adopted it. But see Kuisis v. Baldwin-Lima-Hamilton Corp., 457 Pa. 321, 319 A.2d 914 (1974) (plurality opinion). Since Webb v. Zern, 422 Pa. 424, 220 A.2d 853 (1966), this Court has recognized a plaintiff’s right to pursue an action in strict liability against the manufacturer of a product pursuant to section 402A of the Restatement (Second) of [182]*182Torts.3 A plaintiff presents a prima facie case of strict liability by establishing that the product was defective and that the product caused the plaintiffs injury. Sherk v. Daisy-Heddon, 498 Pa. 594, 598, 450 A.2d 615, 617 (1982). In most instances the plaintiff will produce direct evidence of the product’s defective condition.

368 Pa.Super. 109 at 127, 533 A.2d 739 (1987). We are constrained to disagree.
Although the Superior Court has considered the malfunction theory of strict liability, see Thompson v. Anthony Crane Rental Inc., 325 Pa.Super. 386, 473 A.2d 120 (1984); MacDougall v. Ford Motor Company, 214 Pa.Super. 384, 257 A.2d 676 (1969), this Court has never fully adopted it. But see Kuisis v. Baldwin-Lima-Hamilton Corp., 457 Pa. 321, 319 A.2d 914 (1974) (plurality opinion). Since Webb v. Zern, 422 Pa. 424, 220 A.2d 853 (1966), this Court has recognized a plaintiff’s right to pursue an action in strict liability against the manufacturer of a product pursuant to section 402A of the Restatement (Second) of [182]*182Torts.3 A plaintiff presents a prima facie case of strict liability by establishing that the product was defective and that the product caused the plaintiffs injury. Sherk v. Daisy-Heddon, 498 Pa. 594, 598, 450 A.2d 615, 617 (1982). In most instances the plaintiff will produce direct evidence of the product’s defective condition. In some instances, however, the plaintiff may not be able to prove the precise nature of the defect in which case reliance may be had on the “malfunction” theory of product liability. This theory encompasses nothing more than circumstantial evidence of product malfunction. See MacDougall, 214 Pa.Super. at 391, 257 A.2d at 680. It permits a plaintiff to prove a defect in a product with evidence of the occurrence of a malfunction and with evidence eliminating abnormal use or reasonable, secondary causes for the malfunction. See Thompson, 325 Pa.Super. at 394, 473 A.2d at 125; MacDougall, 214 Pa.Super. at 391, 257 A.2d at 680. It thereby relieves the plaintiff from demonstrating precisely the defect yet it permits the trier-of-fact to infer one existed from evidence of the malfunction, of the absence of abnormal use and of the absence of reasonable, secondary causes. See Thompson, 325 Pa.Super. at 394, 473 A.2d at 125; MacDougall, 214 Pa.Super. at 391, 257 A.2d at 680. We now accept this evidentiary approach as appropriate in ascertaining the existence of a defect in the manufacturing process.
[183]*183At the close of the plaintiffs case-in-chief, a defendant manufacturer will have three evidentiary avenues to pursue: the occurrence of the malfunction, the presence of abnormal use or the presence of reasonable, secondary causes. In this instance Johnson & Johnson attacked the plaintiffs’ evidence eliminating secondary causation by introducing evidence of the doctors’ malpractice. This evidence was sufficient to submit the issue of medical malpractice to the jury. As the Superior Court would have it, however, Johnson & Johnson was entitled to a directed verdict on the malfunction issue once it introduced sufficient evidence of secondary causation, i.e., medical malpractice, to permit this defense to go to the jury.4 We cannot agree with this circular logic as it essentially mandates the grant of a directed verdict should the defendant manufacturer produce any evidence of reasonable, secondary causation.5
[A] directed verdict should not be granted where there are factual questions to be submitted to the jury. If there is any conflict in the evidence, particularly when the evidence consists of oral testimony, if different inferences may reasonably be drawn from the evidence, or if the court would be called upon to pass upon the credibility of [184]*184witnesses or of their testimony, the case is not a proper one for a directed verdict.
9 Standard Pennsylvania Practice 2d, § 58.73 (1982). See also Miller v. Checker Yellow Cab Company of Bethlehem, 465 Pa. 82, 87, 348 A.2d 128, 130 (1975) (trial court must submit negligence questions to jury); East Texas Motor Freight, Diamond Division v. Lloyd, 335 Pa.Super. 464, 470-71, 484 A.2d 797, 800 (1984) (negligence a jury question unless facts leave no room for doubt). In this instance the plaintiffs’ evidence refuted medical malpractice while the defendant manufacturer’s evidence supported it. Depending on which version of the facts the jury chose to believe, which witnesses it deemed credible, in other words how it resolved conflicting evidence, it could have returned a verdict for either party on the issue of malpractice.
The Superior Court erred because it considered incompatible the plaintiffs’ evidence of malfunction in light of the defendant, Johnson & Johnson’s, evidence of a reasonable secondary cause. It rendered impossible the ability of the plaintiffs to negate secondary causes suggested by Johnson & Johnson’s evidence and essentially required a directed verdict in favor of Johnson & Johnson. Contrarily, we believe that so long as the plaintiffs presented a case-in-chief free of secondary causes6 which justified the inference of a defect in the product, the jury was free to accept their scenario.
Nor can we agree with the Superior Court’s tacit conclusion that a plaintiff who has presented a malfunction case will always be precluded from proceeding upon an alternate theory of negligence. It is altogether possible that a plaintiff’s injuries could be caused jointly by a defective product and also by third party negligence so long [185]*185as the negligence does not constitute a supervening cause of the malfunction. “Given the occurrence of a malfunction, the [alleged] negligence assumes legal significance only if it was a superseding cause____ Questions of proximate causation should normally be left to the finder of fact.” Kuisis, 457 Pa. at 330, 319 A.2d at 920.7
For the foregoing reasons, the order of the Superior Court is reversed and the matter is remanded to that Court for expedited consideration of the remaining issues raised by Johnson & Johnson in its initial appeal.
