delivered the opinion of the court:
Plaintiff, Michael P. Darrough, appeals the circuit court’s order granting summary judgment in favor of defendant, Glendale Heights Community Hospital, on plaintiff’s negligence claim. Plaintiff asserts that the circuit court incorrectly concluded that plaintiff had failed to establish a prima facie claim of negligence as a result of the alleged malfunction of the leg rest of defendant’s wheelchair and, therefore, entered summary judgment in favor of defendant as a matter of law. We reverse and remand.
On September 14, 1986, plaintiff injured his knee during a softball game and was taken to defendant’s emergency room. The next morning, a surgeon performed reconstructive surgery and wired together the shattered fragments of plaintiff’s kneеcap, which was then immobilized by placement in a closed cast.
On September 23, 1986, plaintiff was taken from his hospital room to the X-ray department for a chest X ray in an attempt to diagnose an unrelated congestion. An unidentified male candy striper placed plaintiff in a wheelchair, on which the candy striper raised and set a movable leg rest to hold plaintiff’s casted injured leg in a horizontal position parallel to the floor.
The wheelchair was manufactured by defendant, Ivancare, Inc., which was previously granted summary judgment independent of this appeal. The wheelchair was one of two models supplied to defendant, the other not having leg rests. The leg rest in question was contrоlled by a cam-activated lever, which was released to elevate the leg rest and which then automatically locked. The leg rest remained in the position thus set until the cam-activated lever was again released, which would cause the leg rest to immediately drop to its lowest, vertical position perpendicular to the floor.
The candy striper pushed the wheelchair containing plaintiff to the X-ray department without incident. The floor was entirely smooth, and the wheelchair never bumped any walls or doorjambs. An X-ray technician then moved plaintiff from the X-ray department reception room into the X-ray room, took plaintiff’s X rays, and returned plaintiff to the reception roоm, again all without incident and with plaintiff remaining in the wheelchair with his injured leg elevated. Another hospital employee, who was in charge of patient transport, then appeared and began to return plaintiff to his hospital room.
The patient transport employee released the brakes on the wheelchair in which plaintiff was seated, which had been set by the X-ray technician, and began pushing the wheelchair with both hands on the handles protruding from the rear of the wheelchair. Throughout this entire time, plaintiff had kept his hands in his lap and did not touch any part of the wheelchair. The wheelchair had moved less than a single revolution of the rear wheels when the leg support collapsed, and plaintiff’s injured leg fell to the floor. The patient transport employee lifted plaintiff’s casted injured leg, reset the leg rest, and, after checking to be sure the leg rest would hold, once again placed plaintiff’s injured leg on the leg rest. Neither plaintiff nor the patient transport employee knew what had caused the leg rest to collapse.
After returning plaintiff to his room and outside his presence, the patient transport employee inspected the wheelchair and found the leg rest to be operating correctly. Therefore, he returned the wheelchair to stock. As a result, the wheelchair in which plaintiff was sitting when the leg rest collapsed was not identified, and defendant was not able to produce the wheelchair for inspection or testing. However, all wheelchairs purchased when defendant began operations in 1980 were still in service on the date of plaintiff’s injury and at all time relevant to these proceedings. No incidents similar to that which occurred here had occurred either before or after that time.
Plaintiff filed suit and alleged that, as a result of the sudden jarring and bending of plaintiff’s knee within the cast when the leg rest of the wheelchair collapsed, the reconstruction of plaintiff’s knee failed and eventually required the total removal of his kneecap. Specifically, plaintiff’s complaint alleged that defendant “possessed, operated, manаged, maintained and controlled or had a duty to possess, operate, manage, maintain and control, both directly and indirectly, individually and through [its] agents, servants, and employees, a certain wheelchair on the premises [of defendant],” and defendant had “improperly operated, managed, maintained and controlled the aforesaid wheelchair, so that as a direct and proximate result thereof, the Plaintiff was injured.”
Defendant moved for summary judgment and argued this circumstantial evidence permitted multiple inferences as to the cause of the collapse of the leg rest, and, therefore, plaintiff’s assertion that the candy striper had failed to properly set the leg rest was mere conjecture and speculation. Thus, defendant argued, plaintiff had failed to establish a prima facie claim for negligence, and summary judgment was proper. In opposition to defendant’s motion, plaintiff asserted that any multiple inferences permissible from the undisputed, although circumstantial, facts created a material question of fаct precluding summary judgment.
During the hearing on defendant’s motion, defendant argued that defendant did not have exclusive control of the wheelchair because plaintiff had been left unattended for some period of time and may himself have released the leg rest control, cam-activated lever. Plaintiff responded that there was no evidence that plaintiff had done anything to cause the incident or that the wheelchair had collided with anything that could have jarred the leg rest and caused the leg rest to fall. The circuit court asked if plaintiff had a claim for res ipsa loquitur, to which defendant’s counsel responded that plaintiff’s claim sounded only in strict negligence, and defendant’s counsel agаin later during argument asserted that plaintiff had not claimed res ipsa loquitur. The circuit court granted defendant’s motion for summary judgment, and in its letter of opinion expressly noted:
“From the evidence taken as a whole in this case the trier of fact would be left to speculate as to why the leg support fell. Was it a defect in the chair, was it improperly set initially by the candy striper, did the plaintiff himself accidentally bump the release lever, or did it just slip due to the chair being pushed around down to and in and out of the xray [sic] department for some unknown reason. Nothing guides us to a conclusion as to any of these possibilities either directly or circumstantially. This being the case, I have no alternative but to grant defеndant’s motion.”
The circuit court subsequently denied plaintiff’s motion for reconsideration, and plaintiff now appeals, asserting that the circuit court erred as a matter of law in granting defendant’s motion for summary judgment because a material issue of fact existed.
The purpose of a motion for summary judgment is not to try a question of fact, but rather to determinе if a question of fact exists. (Addison v. Whittenberg (1988),
We first note that although the circuit court apparently recognized the applicability of the doctrine of res ipsa loquitur when it inquired whether рlaintiff had made such a claim, both the circuit court and defendant referred to a claim of res ipsa loquitur, which claim is not necessary. Rather, res ipsa loquitur is merely a rule of evidence, which relates to the sufficiency of a plaintiff’s proof (Lynch v. Precision Machine Shop, Ltd. (1982),
To state a claim for negligence, a plaintiff must allege: (1) a duty flowing to the plaintiff from the defendant and (2) breach of such duty, which (3) proximately causes (4) injury to the plaintiff. (Ward v. K mart Corр. (1990),
Res ipsa loquitur does not require absolute and conclusive proof of its foundation. (Barkei v. Delnor Hospital (1988),
In this instance, the alleged negligence occurred when the unidentified candy striper allegedly set the leg rest improperly. Although defendant asserts that plaintiff had control of the wheelchair for a short period of time when he was left to wait in the X-ray reception area for a patient transport employee to return him to his room, there is no evidence that plaintiff did anything to the chair. However, defendant’s own expert testified at his deposition that if plaintiff had released the cam-activated lever controlling the leg rest, it would have immediately fallen. Therefore, thаt the leg rest did not fall until the patient transport employee arrived and resumed control by pushing the wheelchair belies any tampering with the leg rest cam-activated lever by plaintiff. Additionally, plaintiff testified at his own deposition that he never touched the cam-activated lever. Thus, the circumstances supporting an inference of defendant’s negligence are not destroyed by the intervening control plaintiff may have possessed. See Kruger,
Nor do we find that this incident is of a type that normally occurs in the absence of negligence. Defendant’s own employee’s deposition indicated that no similar incident has ever happened before or since, and the deposition of codefendant Ivancare’s expert similarly identified no comparable incidents. Thus, plaintiff sufficiently pleaded facts to support application of the evidentiary doctrine of res ipsa loquitur to survive defendant’s motion for summary judgnlent.
Despite the application of the doctrine of res ipsa loquitur, we also consider defendant’s assertiоn that circumstantial evidence is sufficient only if it permits but one conclusion. (Kellman v. Twin Orchard Country Club (1990),
Finally, the undisputed facts in this instance indicate that plaintiff’s hands remained in his lap the entire time he was in the wheelchair and that, had plaintiff released the cam-activated lever, the leg rest would have immediately fallen and not remained suspended until the patient transport employеe began to push the wheelchair. It is also undisputed that the wheelchair encountered no obstacles between the time the leg rest was set and the time that it fell and that no similar incident with any wheelchair has occurred at any time before or since as a result of mere use of a wheelchair. Despite these facts, the trial court in its letter of opinion based its grant of summary judgment in favor of defendant on the possibility of multiple inferences that included plaintiff’s release of the leg rest himself and the normal use of the wheelchair causing such event. Thus, the trial court not only failed to construe the facts and inferences strongly in favor of plaintiff and against defendant as it was required to so do (In re Estate of Whittington,
For the reasons set forth above, the order of the circuit court granting defendant’s motion for summary judgment is reversed, and the cause is remanded for further proceedings consistent with this opinion.
Reversed and remanded.
