This action was commenced by Flossie Hanson, the plaintiff, to recover damages for personal injuries allegedly sustained as a result of negligence of certain agents and employees of the defendants John E. McDonald, a licensed medical doctor, and the Orthopedic Clinic, a co-partnership. The parties will be referred to in this opinion by their trial court designations.
The plaintiff’s petition alleged that she was receiving therapy treatments under the direction of Dr. McDonald at the Clinic operated by the partnership, which treatments were administered by the agents and employees of the defendants. The plaintiff further alleged that on March IS, 1961, while receiving therapy treatment from a machine designed to give electrical shock treatments, known as a medcolator, she received a third degree burn on her ankle either because the machine was defective or because it was improperly operated. The case was tried to a jury and resulted in a verdict for the plaintiff. From this verdict and the judgment of the trial court overruling defendant’s motion for a new trial, the defendants have appealed to this court by petition in error with case made attached.
The history of the plaintiff’s condition preceding this action is not in dispute. She sustained an injury to her back when she slipped and fell at a local grocery store on November 9, 1959. As a result she began experiencing soreness and stiffness in her lower back and pain radiated down her left leg. Her symptoms persisted during treatment by Dr. W. H. Morton, her family physician, and on March 3, 1960, he referred her to Dr. McDonald, a specialist in orthopedic surgery. On March 21, 1960, Dr. McDonald performed a laminectomy upon plaintiff and repaired a ruptured disc in her spinal column. Plaintiff was then treated by means of heat and massage applied to her lower back. In June, 1960, Dr. McDonald prescribed therapy treatments for the plaintiff’s left leg. This treatment was conducted in the therapy department of the Orthopedic Clinic and included whirlpool, hand massage, and the medcolator. The purpose of this therapy treatment, according to Dr. McDonald, was to stimulate and rehabilitate weakened muscles in the plaintiff’s leg. Plaintiff does not contend that Dr. McDonald did not use proper professional skill and judgment in making his diagnosis, in performing surgery, or in prescribing the postoperative treatment; but asserts that the technician in charge of the medcolator negligently burned her ankle during one of the therapy treatments.
The medcolator is a therapy machine designed to produce an artificial stimulation of the muscles of the patient by means of electrical shock. The current flows from a transducer (an object that looked like a door knob), through the patient, and into a ground pad. The movable transducer is applied to the patient by the operator and the ground pad is placed under the patient’s body in the area where the transducer is being applied.
The plaintiff testified that she had received approximately 50 treatments with the medcolator prior to March 15, 1961, the date she sustained the injury complained of. On one previous occasion, plaintiff complained that the machine was stinging her when the voltage setting was increased. According to the plaintiff, she had no other difficulty with the machine until March 15, 1961. On this occasion the operator of the machine attempted to begin the treatment but nothing happened. The operator then put water on ground pad, which was hard and crusty, and adjusted the machine. When the machine did start, it immediately began stinging and burning the plaintiffs leg causing the plaintiff to state to the operator “Blanche, this thing is burning me, stop it”, to which the operator purportedly replied, “Flossie, I am sorry, I will have
Doctor W. A. Morton testified for the plaintiff. He stated that he had been a general practitioner in Tulsa, Oklahoma, since 1937 and that he was the plaintiff’s family physician; that he had originally sent her to Dr. McDonald; that she subsequently returned to his care in the summer of 1961 for treatment of an ulcer on her ankle; that she gave him a history at that time of having sustained the injury by being burned by equipment at the Orthopedic Clinic; and that he hospitalized the plaintiff and treated the ulcer. He further testified that he was unable to diagnose the cause of the ulcer on plaintiff’s ankle, but that it was not incompatible with having been caused by an electrical burn. On cross-examination he also acknowledged that the ulcer could have been caused by poor circulation but stated that it did not possess all the characteristics of an ulcer of that type.
This concluded the plaintiff’s case-in-chief to which the defendants entered a demurrer to the evidence for failure to prove a cause of action against them. This demurrer was overruled by the court and the defendants proceeded to present their evidence.
The evidence for the defense was presented by Dr. McDonald, and three female employees of the Clinic. The employee, who operated the medcolator, denied that plaintiff ever sustained a burn while being treated with that machine. She admitted on cross-examination that it would not be proper for her to attempt to fix the machine if anything was wrang with it but that she should immediately shut it off and report the difficulty to her supervisor. She further recalled that there was one occasion during the treatment of the plaintiff when the current would not come through the transducer. She stated that when she was able to get the current started on this occasion “I was not getting the reaction I wanted”.
Dr. McDonald testified that he has been engaged in the practice of medicine since 1928 and specializes in orthopedic surgery. He testified in some detail concerning the history of the plaintiff’s injury, the surgery performed, and his reasons for prescribing physical therapy. He expressed the opinion that the ulcer on plaintiff’s leg did not have the appearance of an electrical burn. It was his diagnosis that the condition resulted primarily from poor blood circulation in the plaintiff’s leg.
The remaining two witnesses, nurses at the Clinic, testified that they had treated
It is the first contention of the defendants that the trial court erred in not directing a verdict for the defendants at the close of all the evidence.
It is well settled that in determining whether the plaintiff’s evidence is sufficient to withstand defendant’s motion for a directed verdict, the trial court should consider as true all of the evidence favorable to the plaintiff together with all reasonable inferences to be drawn therefrom, and should disregard all conflicting evidence favorable to the defendant. Sisler v. Whitten, Okl.,
In support of their contention, the defendants’ first argument is that expert testimony was required to establish that the plaintiff sustained a burn and that the medcolator was capable of causing this burn.
Plaintiff’s testimony as to the manner in which the injury occurred was unequivocal and certain. She testified that on March 15, 1961, when the treatment with the medcolator began she felt a stinging and burning sensation upon her ankle where the transducer was being applied; she then observed that the area of the ankle to which the transducer had been applied was turning “real pink”; and she further observed that within a short time the area blistered, burst and the outer skin came off. tier expert witness, Dr. Morton, testified that the ulcerated condition of her ankle was consistent with having been caused by an electrical burn. He further testified that the ulcer, in his opinion, did not possess all the characteristics of a circulatory ulcer as diagnosed by Dr. McDonald. The jury was not bound to accept the testimony of the defendants’ expert witness in this situation as to the nature and cause of plaintiff’s injury. This court adheres to the view that the weight to be accorded to expert testimony is to be determined by the trier of facts. Mid-Continent Pipe Line Co. v. Price,
We recognize, as the defendants point out, that in certain cases the injury is of such a character that expert medical testimony is required to establish its cause or origin. See, e. g., Veale Electric Co. v. Carmichael,
We conclude that the plaintiff’s testimony concerning the manner in which her injury was sustained was competent and was sufficient to make out a prima facie case that she was burned and that the medcolator was the cause of the injury. Indeed, accepting her account of the incident as true, as we must on this appeal, it would be unreasonable to conclude that the injury could have resulted from any other source. If, as the defendants assert, the medcolator may have been incapable of causing such a burn, the burden was upon them to establish this fact to rebut the plaintiff’s evidence, and this they did not do. See John A. Brown Co. v. Shelton, Okl.,
The defendants next contend that, even if the plaintiff was burned and the therapy machine did it, the evidence is insufficient to establish negligent operation of the medcolator.
The defendants stipulated that the operator of the medcolator and the nurses in the Orthopedic Clinic were the employees of the defendants and were acting under the supervision and control of the Dr. McDonald in performing therapy treatment upon the plaintiff. The defendants do not deny that they are responsible for the negligent conduct of their employees in connection with this treatment, Emerson v. Chapman,
The evidence established that if any difficulty arose in connection with the therapy machine, the operator, who was not a nurse and who possessed no scientific knowledge concerning how this “highly technical” machine worked, was to immediately shut off the machine and report the matter to her supervisor. The plaintiff testified that the operator had considerable difficulty with the machine during the therapy treatment in which she was burned but made no attempt to contact her supervisor and instead attempted to correct the malfunction herself. The operator denied this, but after considerable cross-examination did recall that on one occasion, near the time plaintiff claimed to have been burned, she did have difficulty starting the machine and testified that when the machine did start “I was not getting the reaction I wanted”. Further, the plaintiff testified that immediately following her complaint of being burned, the operator stated “Flossie, I am sorry, I will have this thing worked on tomorrow”. It is reasonable to conclude from this admission that the operator was aware of a defect in the machine at the time the treatment was administered, but proceeded with the treatment despite this fact and contrary to her supervisor’s instructions. The evidence is not in dispute that the therapy treatment was not supposed to burn the plaintiff and that she had not suffered any ill effects from the 50 previous treatments. It is also not disputed that the plaintiff did develop an ulcer on her ankle at approximately the time she claims this incident occurred. Under these circumstances, we believe the matter was properly submitted to the jury to determine whether the injury occurred as a result of the negligent operation of the therapy machine or use of the machine with knowledge of its defective condition, or whether the condition developed from poor circulation in the plaintiff’s leg as contended by the defendants.
The defendants contend that the trial court erroneously submitted the case to the jury on the theory of res ipsa loquitur, and that this doctrine is inapplicable in malpractice cases. Hembree v. Von Keller,
We conclude, after careful review of the record, that the evidence is sufficient to support the determination of the jury that the plaintiff was injured through the negligence of the defendants.
The defendants also contend that the court did not properly instruct the jury concerning the standard of care required of the defendants in a malpractice case.
This is not the “usual” malpractice case. See Duke Sanitarium v. Hearn,
“It is true that the court’s instructions which defined the defendant’s duty, generally, as being simply 'reasonable and ordinary skill and care’ might without error have been amplified to prescribe the skill and care which a ‘reasonable and ordinary member of his profession would exercise under similar circumstances,’ but this would have required of the defendant a higher degree of care and skill than the instructions given. We believe, however, that the instructions given were broad enough to include the proper measure of the defendant’s duty toward the plaintiff. * * *”
As the instruction given were more favorable to the defendants than those which they assert they were entitled to receive, the defendants have no basis for complaint. Stagner v. Files, supra; American Life Ass’n v. Rogers, Okl.,
The evidence presented is sufficient to support the jury’s finding that the defendants negligently burned the plaintiff with their therapy machine, and the instructions given were fair, and favorable to the defendants. The judgment of the trial court is affirmed.
