MALLETT, J.

In this medical malpractice action, the trial judge granted defendants' motion for a directed verdict at the close of the plaintiffs' proofs. The Court of Appeals affirmed, finding that plaintiff had failed to make a prima facie showing of the standard of care related to defendants' allegedly negligent conduct.

We affirm.

I

On August 5, 1981, plaintiff Shirley Locke underwent a vaginal hysterectomy with entocele and rectocele repair at the University of Michigan Hospital. The procedure was performed by defendant, Dr. Judith Pachtman, then a fourth-year resident in gynecology. Codefendant, Dr. James Roberts, was the attending physician and was present for most of the surgery.

Dr. Pachtman testified that she performed the first two procedures, the hysterectomy and entocele repair, without complication, although the entocele repair took longer than expected. Following the entocele repair, Dr. Roberts left the room to attend another operation that had been previously scheduled.

Dr. Pachtman then began the rectocele repair. Upon Dr. Pachtman's initial insertion into the levator ani muscle, the needle she was using broke. One-half to two-thirds of the needle, a length of about 1.5 cm, broke off and lodged somewhere within that muscle. Dr. Pachtman searched unsuccessfully for the broken portion of the needle for fifteen to twenty minutes. At that time, Dr. Roberts returned and joined Dr. Pachtman in searching for the needle fragment.

Drs. Pachtman and Roberts utilized a silver probe to x-ray the affected area, in an attempt to locate the broken portion of the needle. After ascertaining the approximate location of the fragment, they decided to close the old incision and to continue their search through a new incision. After unsuccessfully searching for the needle for another forty-five minutes to one hour, they abandoned the search and closed the second incision. Both doctors indicated that they felt it was in the plaintiff's best interest to terminate the surgery at that point, even though they had failed to locate the needle fragment.

Plaintiff testified that after the surgery Dr. Pachtman informed her of the needle breakage and stated that the needle was entrenched in the muscle and therefore could remain there without causing her any problems. However, after experiencing considerable pain and discomfort, plaintiff consulted with another physician, Dr. Frances Couch. Dr. Couch advised removing the needle fragment, and, subsequently, she performed the surgical procedure, successfully locating and removing the broken portion of the needle.

Plaintiff filed suit against Drs. Pachtman and Roberts, alleging negligence on various grounds, including the use of a needle that they knew or should have known was too small and failing to locate and remove the needle fragment. Plaintiff claimed that she suffers from severe pain, disfigurement, and limitation of body movement and functions, as well as experiencing mental and emotional distress. Plaintiff's husband, Danny Locke, filed a derivative claim.

In testimony presented at trial, plaintiffs' expert witness, Dr. Couch, was unable to identify any negligent conduct on the part of either Dr. Pachtman or Dr. Roberts. Dr. Couch also stated that she could not give an opinion regarding the adequacy of the needle size, because she had never viewed the needle intact. She explained that she could not identify the size of the needle without viewing the needle in its entirety.

When questioned generally regarding the cause of needle breakage and its relation to the standard of care, Dr. Couch made two separate statements. At one point Dr. Couch stated that the standard of care did not relate to needle breakage at all, but rather to how one dealt with it, suggesting that needle breakage was simply one of the risks of surgery. Later, without relating this point to a standard of care, she noted that a surgeon's "incorrect technique" often causes a needle to break. When asked to describe what she meant by incorrect technique, Dr. Couch described instances in which a surgeon fails to manipulate the needle correctly, such as by inserting it at the wrong angle or applying too much force. Dr. Couch also testified that she had previously had a needle break while performing surgery.

In addition to Dr. Couch's expert testimony, plaintiffs introduced evidence regarding a number of statements allegedly made by Dr. Pachtman following the surgery.

Plaintiff's brother, Reverend Gary Heniser, testified that, while he was at the hospital visiting his sister, Dr. Pachtman told him, "`I knew the needle was too small when I used it.'"

Coplaintiff Danny Locke testified that Dr. Pachtman had also spoken to him about the surgery: "[S]he told me that it was her fault, that she used the wrong needle, and she was sorry."

Finally, Shirley Locke testified that Dr. Pachtman had told her:

"I knew that needle was too small when the new scrub nurse handed it to me. It wasn't her fault because she was new, but I chose to use it anyway and it's my fault and I am really sorry. . . ."[]

Both Dr. Pachtman and Dr. Roberts testified at trial. Neither acknowledged any negligent behavior in the choice of needle, the needle breakage, or their subsequent search for the needle fragment.

At the close of plaintiffs' proofs, the trial court granted defendants' motion for directed verdict on the ground that plaintiffs had failed to make a prima facie showing regarding the standard of care. Plaintiffs' motion for a new trial was denied, and, in a divided opinion, the Court of Appeals affirmed. This Court granted leave to appeal. 444 Mich. 893 (1993).

II

Proof of a medical malpractice claim requires the demonstration of the following four factors: (1) the applicable standard of care, (2) breach of that standard of care by the defendant, (3) injury, and (4) proximate causation between the alleged breach and the injury. MCL 600.2912a; MSA 27A.2912(1). To survive a motion for directed verdict, the plaintiff must make a prima facie showing regarding each of the above elements.

Plaintiffs argue that the lower courts erred in finding that they had failed to demonstrate the standard of care applicable to defendants' conduct. Plaintiffs contend that expert testimony was sufficient to establish this point, and, further, that the standard of care and breach of that standard were inferable under the doctrine of res ipsa loquitur and because the alleged negligence was within the common understanding of the jury.

We agree with the lower courts' determination that no prima facie showing was made, and therefore we affirm the directed verdict entered for the defendants.

III

When evaluating a motion for directed verdict, the court must consider the evidence in the light most favorable to the nonmoving party, making all reasonable inferences in the nonmoving party's favor. Beals v Walker, 416 Mich. 469, 480; 331 N.W.2d 700 (1982).

Because different theories of recovery are involved, we will address the claims against each defendant individually.

A

Plaintiffs argue first that the standard of care attributable to Dr. Pachtman was established by way of expert testimony. This Court has long recognized the importance of expert testimony in establishing a medical malpractice claim, and the need to educate the jury and the court regarding matters not within their common purview. As we have previously explained:

In a case involving professional service the ordinary layman is not equipped by common knowledge and experience to judge of the skill and competence of that service and determine whether it squares with the standard of such professional practice in the community. For that, the aid of expert testimony from those learned in the profession involved is required. [ Lince v Monson, 363 Mich. 135, 140; 108 N.W.2d 845 (1961).]

While we have recognized exceptions to this requirement, the benefit of expert testimony, particularly in demonstrating the applicable standard of care, cannot be overstated.

In this case, plaintiffs contend that the standard of care applicable to Dr. Pachtman was established by Dr. Couch's expert testimony. For this point, plaintiffs rely on Dr. Couch's statement that needle breakage often occurs because of the surgeon's "incorrect technique." Plaintiffs assert that this testimony, coupled with Dr. Pachtman's admissions regarding use of a needle she knew to be too small, were sufficient to establish the standard of care and breach of that standard.

Dr. Couch's testimony with regard to the standard of care associated with needle breakage was rather confused. At one point she suggested that needle breakage was merely one of the risks of surgery, and that needle breakage did not ordinarily signal a violation of the standard of care:

Q. Do you feel that when a needle breaks off during a hysterectomy procedure as in this case that it is not a standard of care question but rather is just one of the contemplated risks of such surgery?

A. Yes, that is correct. It's not a standard of care. You always know that there will be something, maybe some equipment failure but standard of care is how you deal with the situation.

Dr. Couch later testified that needle breakage may be attributable to a surgeon's "incorrect technique":

Q. From your experience and your training can the manner in which a surgeon utilizes a needle cause it to break?

A. I would say most of the time that's the case. It's a matter of incorrect technique.

A. Well, a needle is curved. If you forget the needle is curved and you push against the curve instead of with the curve the needle will break. If you try to put a needle through an instrument it doesn't go through steel. If it's not positioned correctly in a tissue and you're trying to draw it through against a clamp it will break. It will break. . .

* * *

A. Generally that's most of the reason why they break. You are putting force against where it wasn't made to be put against.

As the lower courts found, it is indeed questionable whether Dr. Couch's latter testimony on this point was sufficient to establish a standard of care with regard to "incorrect technique." Dr. Couch, while presenting one way in which needles break, never went so far as to relate that discussion to a standard of care. In effect, she never explained what a reasonably prudent surgeon would do, in keeping with the standards of professional practice, that might not have been done by Dr. Pachtman. Accordingly, the jury would have had no standard against which to measure Dr. Pachtman's conduct. This factor, coupled with the conflicting nature of Dr. Couch's testimony, leads us to believe that the standard of care was not sufficiently established.

We further note that Dr. Couch's explanation of how and why needles break, even had it established a standard of care, provides little support for the specific theory of negligence advanced by plaintiffs in the complaint and at trial. While plaintiffs argued that the needle broke in this case because it was of an inadequate size for the area to be sutured, Dr. Couch's description of "incorrect technique" leading to needle breakage related to the way the chosen needle is positioned and manipulated, regardless of its size. Dr. Couch did acknowledge at one point that there is such a thing as using a needle that is too small or too weak for a particular task. However, she never related this to her theory of "incorrect technique," nor did she indicate that the needle utilized by defendants was of an inappropriate size. We find her statement, either standing alone or in conjunction with her testimony regarding incorrect technique, to be insufficient to establish a standard of care. Therefore, no prima facie showing was made.

B

Plaintiffs next argue that the statements allegedly made by Dr. Pachtman were themselves sufficient to establish the standard of care and breach of that standard. Plaintiffs contend that their case is governed by this Court's decision in Orozco v Henry Ford Hosp, 408 Mich. 248; 290 N.W.2d 363 (1980), and that, under the reasoning presented in Orozco, the lower courts erred in finding that defendant's admissions alone were insufficient to establish the standard of care.

Plaintiffs' reliance upon Orozco is misplaced. In Orozco, the plaintiff testified that during his hernial surgery he heard one of the surgeons say, "Oops, I cut in the wrong place." Id. at 254. Following the surgery, one of his testicles atrophied. At trial, an expert witness testified that this injury was likely due to an impairment of the blood supply to the testicles during the surgery.

At the close of Orozco's proofs, the trial court granted the defendants' motion for a directed verdict, and the Court of Appeals affirmed, finding that the plaintiff had failed to make a prima facie showing of the applicable standard of care. This Court reversed the Court of Appeals by per curiam opinion. The Court found that expert testimony was not necessary because jury members would be able to determine, from their own common knowledge, whether the defendants' actions violated the applicable standard of care. As the Court explained:

Here Orozco offered the fact of the injury, a medical explanation of how that injury likely occurred, and an admission by the surgeon that he cut in the wrong place.

Paraphrasing Lince, "[t]he question is whether the action of defendants conformed to standards of good practice in the community. Common knowledge and the experience of ordinary laymen do . . . equip them to give the answer in a case such as this" when an expert testifies that the likely cause of injury was an impairment of the blood supply to the testicles in the course of the operation and the plaintiff testifies that the surgeon said, "Oops, I cut in the wrong place." [ 408 Mich. 253-254. Emphasis in original.]

As is indicated above, the Court in Orozco did not rely exclusively upon the defendant's admission to find that a prima facie showing had been made. Rather, the Court found that on the basis of that admission and corroborating expert testimony the jury could determine from their own common knowledge whether the defendants' actions conformed to standards of professional practice. This decision was in line with previous case law holding that expert testimony is not normally required where the defendant mistakenly treated or did injury to a portion of the body that was free of disease and not designated for treatment. Sullivan v Russell, 417 Mich. 398, 408; 338 N.W.2d 181 (1983) (no expert testimony was necessary where a dentist mistakenly ground three of the plaintiff's teeth not intended for treatment); Higdon v Carlebach, 348 Mich. 363, 374; 83 N.W.2d 296 (1957) (expert testimony was not required where a dentist, using a rotating disk to separate two of the plaintiff's teeth, mistakenly cut into her tongue).

Turning to the present case, we hold that the lower courts correctly concluded that Dr. Pachtman's statements were insufficient to make a prima facie showing. While the statements may have indicated Dr. Pachtman's belief that she made a mistake or acted in error, a jury could not reasonably infer from those statements alone that Dr. Pachtman's actions did not conform to the standard of professional practice for the community as a whole.

Unlike the situation presented in Orozco, the standard of care associated with needle choice and needle breakage is not accessible to the jury absent expert guidance. Plaintiffs have provided no guidance with regard to what options were available to Dr. Pachtman and which of them she should have chosen. In short, there was no testimony regarding what a reasonably prudent surgeon would have done in Dr. Pachtman's situation. We agree with the Court of Appeals determination that the jury should not be left to speculate in this regard. It is precisely to avoid such speculation that expert testimony is ordinarily required.

Accordingly, without diminishing the holding in Orozco, we decline to extend it to the present case, in which the standard of care associated with the alleged negligence is not within the common knowledge of the jury, it cannot be reasonably inferred from the admissions alone, and where no further evidence was presented linking Dr. Pachtman's admissions to the standard of care. While it is conceivable that in some circumstances a doctor defendant's extrajudicial admissions could present prima facie evidence of breach of the standard of care, that is not the case here.

C

Plaintiffs next argue that even if expert testimony was insufficient, the case against Dr. Pachtman should have proceeded to the jury on the theory of res ipsa loquitur. Specifically, plaintiffs contend, under this doctrine, a prima facie case was made, with regard to both the needle breakage and the fact that defendant terminated the surgery without having recovered the needle. The lower courts rejected these arguments, as do we.

As previously noted, while expert testimony is the traditional and the preferred method of proving medical malpractice, exceptions to the need for expert testimony have been recognized. One such exception involves the doctrine of res ipsa loquitur. If a plaintiff's case satisfies the dictates of this doctrine, then the case may proceed to the jury without expert testimony.

This Court's decision in Jones v Porretta, 428 Mich. 132; 405 N.W.2d 863 (1987), marked the Court's first explicit adoption and application of res ipsa loquitur in the medical malpractice context. In Jones, the Court cited the following four factors as necessary to a res ipsa loquitur claim:

(1) the event must be of a kind which ordinarily does not occur in the absence of someone's negligence;

(2) it must be caused by an agency or instrumentality within the exclusive control of the defendant;

(3) it must not have been due to any voluntary action or contribution on the part of the plaintiff. . . .

[4] "[e]vidence of the true explanation of the event must be more readily accessible to the defendant than to the plaintiff." [ Id. at 150-151.]

In the medical malpractice context, the crucial element, and that most difficult to establish, will often be the first factor, i.e., that the event is of a kind that does not ordinarily occur in the absence of negligence. A bad result will not itself be sufficient to satisfy that condition. As the Court explained:

This does not mean that a bad result cannot be presented by plaintiffs as part of their evidence of negligence, but, rather, that, standing alone, it is not adequate to create an issue for the jury. Something more is required, be it the common knowledge that the injury does not ordinarily occur without negligence or expert testimony to that effect. [ Id. at 154. Emphasis added.]

Therefore, the fact that the injury complained of does not ordinarily occur in the absence of negligence must either be supported by expert testimony or must be within the common understanding of the jury. Neither standard was met here.

Plaintiffs first argue that expert testimony was sufficient for the jury to find that needle breakage does not ordinarily occur without negligence. We disagree. Even plaintiffs' own expert acknowledged at one point that needle breakage is one of the risks of surgery, suggesting that faulty equipment might be a cause of breakage. Therefore no prima facie showing was made.

In the alternative, plaintiffs contend that no expert testimony is required because it is within the common understanding of the jury that needles do not ordinarily break absent negligence. For this theory, plaintiffs rely on this Court's holding in LeFaive v Asselin, 262 Mich. 443; 247 N.W. 911 (1933). In LeFaive, the Court held that a jury could determine, without the aid of expert testimony, that the defendant's action in inadvertently leaving a needle within the plaintiff's incision violated the applicable standard of care.

Plaintiffs' analogy to LeFaive is inapposite. In LeFaive, the act of leaving the needle within the incision was one of carelessness, from which negligence may easily be discerned. However, a far different situation is presented where a needle breaks off, and the surgeon, despite attempts to locate the fragment is unable to. One could not reasonably conclude, on the basis of common knowledge, that such an event does not ordinarily occur in the absence of negligence. Where negligence is not inferable through common knowledge, and where no expert testimony was presented to the effect that the event complained of would not ordinarily occur without negligence, plaintiffs' res ipsa loquitur claim must fail.

D

Lastly, plaintiffs contend that a prima facie case was made against Dr. Pachtman because the negligence alleged was so gross as to be within the common understanding of the jury.

This Court has previously held that expert testimony may not be required when

"the lack of professional care is so manifest that it would be within the common knowledge and experience of the ordinary layman that the conduct was careless and not conformable to the standards of professional practice and care employed in the community." [ Sullivan, 417 Mich. 407, quoting Lince, 363 Mich. 141. ]

However, as was discussed in parts B and C, we do not find the standard of care with relation to Dr. Pachtman's allegedly negligent use of an inadequately sized needle to be within the common understanding of the jury. Nor do we find the standard of care applicable to defendants' decision to terminate the surgery, without having recovered the needle, to be ascertainable by the jury without the aid of expert testimony.

E

Plaintiffs assert liability against Dr. Roberts on two grounds: (1) vicarious liability for the negligent acts of Dr. Pachtman, and (2) negligent supervision. However, plaintiffs failed to establish a prima facie case under either standard.

Plaintiffs' vicarious liability claim fails because it presupposes negligent conduct on Dr. Pachtman's behalf. As previously discussed, plaintiffs have failed to establish a prima facie case of liability against Dr. Pachtman.

Plaintiffs' negligent supervision claim is also not supported by the record. There was uncontroverted testimony, including testimony from plaintiffs' own expert, to the fact that it was not unusual for an attending physician at University of Michigan Hospital to leave a resident alone during portions of a procedure. There was no testimony suggesting that such action was violative of a standard of care, nor do we find that point inferable by the jury. Therefore this claim is also without merit.

IV

We agree with the lower courts' determination that plaintiffs failed to establish a prima facie case of medical malpractice against either Dr. Pachtman or Dr. Roberts.

We affirm.
