This rule has been applied with reference to expert medical testimony. In McGrady v. Brink, 195 Wash. 626, 629, 81 P.2d 800 (1938), a medical witness had testified, “I don’t know what the cause of death was.” He also testified, “in my opinion, I am inclined to think this hemostat would naturally in the ordinary course of events cause death; I think that it probably would.” This court then stated:
Mention is made that this witness also testified that “I don’t know what the cause of death was.” But that does not destroy the effect of his other testimony. Even if it be assumed that the testimony of the witness was inconsistent in certain particulars, the question would still be one for the jury, because the respondent was entitled to that version of the evidence which was most favorable to her.
It was within the province of the jury to reconcile inconsistencies, if any, in the testimony of Dr. Gross. They evidently believed him when he stated his answer was “based upon reasonable medical certainty.” We hasten to add that there are other instances in Dr. Gross’ testimony which satisfy the requirements as to reasonable medical certainty.
The second prong of the defendants’ fourth assignment of error relates to Dr. Gross’ testimony as to the surgical procedure involved in repairing a ruptured disc. It appears that on cross-examination defendants’ counsel brought out that the only way to demonstrate with 100 per cent accuracy that a patient has a ruptured disc is to do surgery to inspect the disc and in the instant case no surgery had been done. This would affect the weight of the witness’s testimony on diagnosis. Dr. Gross was then permitted to testify as to the severity of surgery as a diagnostic tool. The defendants, having opened the door as to the use of surgery as a diagnostic technique, no error was committed by the trial court in admitting the above-described testimony of Dr. Gross.
The judgment is affirmed.
