Opinion

ORTEGA, P. J.

Plaintiff Peggy Trees appeals from a judgment entered after the trial court granted a directed verdict to defendants, Dr. Julio Ordonez and his professional corporation, in a medical malpractice case.1 Ordonez, a neurosurgeon, performed surgery to fuse three vertebrae in plaintiffs neck, and she later suffered adverse medical consequences that required additional surgeries and left her with permanent disabilities. Plaintiff filed a negligence action against defendant and two other doctors who participated in her care, claiming, among other things, that Ordonez breached the standard of care by failing to properly place and secure the plate used to stabilize plaintiffs cervical spine, resulting in plaintiffs injuries. Plaintiffs case at trial included expert testimony from a biomechanical engineer about the function of the plate, opining that Ordonez’s installation of the plate was inconsistent with the manufacturer’s explicit instructions.

Defendant moved for a directed verdict on the grounds that plaintiff failed to provide evidence of causation or negligence. The trial court granted a directed verdict, concluding that, although there was sufficient evidence of causation, plaintiff had failed to provide expert testimony that defendant violated the applicable standard of care. Plaintiff appeals from the resulting judgment, assigning error to the trial court’s grant of the directed verdict and its evidentiary ruling that prevented her expert biomechanical engineer from testifying about matters related to causation. Defendant cross-assigns error, asserting that the trial court allowed objectionable evidence into the record and that the trial court should have granted a directed verdict on causation. Because we affirm on the appeal issues, we need not address the issues raised in defendant’s cross-assignments of error.

I. FACTS

In an appeal from a directed verdict, we view the evidence in the light most favorable to the nonmoving party and [232]*232extend to that party the benefit of any inferences that can be drawn from the evidence. Shockey v. City of Portland, 313 Or 414, 422-23, 837 P2d 505 (1992), cert den, 507 US 1017 (1993). Accordingly, we state the facts in the light most favorable to plaintiff.

In order to perform an anterior cervical decompression and fusion on plaintiff, Ordonez had to approach through plaintiffs neck and retract her esophagus, hypo-pharynx, and trachea away from the anterior surface of her cervical spine. Ordonez removed bone and intervertebral disc material from the spaces between C4 and C5 and between C5 and C6 and placed bone grafts into the spaces between the vertebrae. Ordonez then stabilized the vertebrae and grafts by affixing a titanium plate to the anterior surface of plaintiffs cervical spine with bone screws driven into plaintiffs vertebrae. Ordonez used a “size 28” Cervical Spine Locking Plate, which is affixed to the vertebrae by bone screws with expanding heads. To prevent the bone screws from “backing out,” the physician must also insert and tighten “locking screws” into the heads of the bone screws.

Approximately 36 hours after the surgery, plaintiff complained of severe neck pain and the sensation that she had a “plate in her throat.” A subsequent image of the area showed a large abscess directly in front of the plate. During a second surgery to address the abscess, Ordonez discovered that the original surgical wound around the cervical spine was contaminated with oral bacteria and amylase, which could be caused by a perforated esophagus. He removed purulent material from the neck, installed a drain at C4, and began irrigating the wound with antibiotics. Despite these efforts, over the next several days, plaintiffs condition worsened and she exhibited the beginning signs of paralysis.

Plaintiff underwent three additional surgeries to remove epidural abscesses that were closing off her spinal canal. In the last of these surgeries, Dr. Silver, filling in for Ordonez, removed the plate, screws, and grafts installed in the first surgery and placed plaintiff in a halo framework to stabilize her spine.

Although plaintiffs condition improved, she required additional surgeries in the months that followed. [233]*233Ultimately, her entire cervical spine was fused and she now suffers from weakness in both arms, partial paralysis of the left upper arm, and unremitting pain, and she cannot work in her profession.

Plaintiffs medical malpractice complaint against the various defendants2 sought economic and noneconomic damages and alleged, among other things, that Ordonez failed to exercise due care during the first surgery to avoid perforating plaintiffs esophagus or hypopharynx. Specifically, plaintiff alleged that Ordonez failed to properly place and secure the plate and its screws to the anterior surface of the vertebrae, which resulted in the perforation and erosion of plaintiffs esophagus or hypopharynx. Plaintiff also alleged that defendant negligently failed to detect and repair that perforation, and she raised other allegations relating to informed consent that are not at issue in this appeal.

At trial, plaintiff presented testimony from Dr. Tencer, who teaches biomechanics in the department of orthopedic surgery at the University of Washington. Trained as an engineer and not as a medical doctor, Tencer testified that he performed a biomechanical assessment of Ordonez’s installation of the plate in plaintiff, based on plaintiffs medical records and on manuals from Synthes, the manufacturer of the plate. Tencer opined that Ordonez’s choice and installation of a size 28 plate was improper. He noted that longer plates were available for defendant’s use, and that the use of the size 28 plate forced Ordonez to angle the screws to such an extent that they did not “sit down” in the plate. According to Tencer, because the screws protruded above the surface of the plate, they came into contact with the soft tissue of the esophagus, forcing the esophagus tissue to conform around the sharp edges of the screw heads. He also testified that the instruction manual that accompanied the plate specifically warned that improper screw and plate fixation created a risk of esophageal erosion.3

[234]*234Tencer explained that, from a biomechanical standpoint, if the screws are not completely threaded into the vertebrae they can pop out of the plate, allowing the plate to loosen. He also testified that the bone screws are designed with sharp expanding edges so that when the locking screw is inserted into the bone screw, it creates a mechanical lock by forcing the head of the bone screw outwards against the inner edge of the hole in the plate. Accordingly, Tencer opined that the soft tissue of the esophagus must be protected by ensuring that the screws sit flush with the plate. If the screws are not below or flush with the surface of the plate, the locking screws can distort the bone screw edges and result in a sharp edge protruding above the plate. Tencer explained that X-rays of plaintiff revealed that five of the six screws used by defendant were not flush with the plate’s surface; accordingly, he opined that the locking mechanism was not functioning properly. He noted that, from a biomechanical standpoint, the situation that existed after plaintiffs surgery presented an opportunity for plaintiffs esophagus to have contact with the protruding screws.
