it to the hip or femoral head, or both. Therefore, they would have expected the body to continue to control and eradicate the infection, without the use of antibiotics. I don’t know this, but this is suspect.” Dr. Schnell was then asked this question: “Doctor, do you have an opinion, based upon reasonable medical certainty, and based upon your qualifications and experience, and your review of those documents presented to you by plaintiff’s attorneys, whether the condition of Mrs. Jean Bryant would be any different today if in fact she had the hardware removed in January of 1966 and then she was placed in a spica cast in an attempt to — in an attempted voluntary fusion?” Dr. Schnell responded: “No, I think the end result could have been the same.” Later he acknowledged that his answer would probably be the same if similar treatment had been instituted in December of 1965.
In Iowa, the issue of proximate cause is ordinarily for the jury where there is substantial evidence of a defendant’s negligence. Wilson v. Corbin, supra, 41 N.W.2d at 708. But the evidence adduced by the plaintiff must show that “plaintiff’s theory is reasonably probable, not merely possible, and more probable than any other theory based thereon. It is not necessary that the proof be conclusive or exclude every other suggested or possible cause.” Stickleman v. Synhorst, supra, 52 N.W. at 507.
In this case, the evidence may have shown that it was possible that the failure to diagnose and treat the infection contributed to the disability of Mrs. Bryant, but it certainly could not be interpreted as haying shown that it was reasonably probable or “more probable than any other theory” to have been the cause of Mrs. Bryant’s condition.
In Barnes v. Bovenmeyer, 255 Iowa 220, 122 N.W.2d 312, 316-317 (1963), the Iowa Supreme Court made it clear that proof of negligence alone does not entitle a plaintiff to go to a jury in a malpractice case. “There must also be substantial .evidence that it was the proximate cause of plaintiff’s damage.” See also Ramberg v. Morgan, 209 Iowa 474, 218 N.W. 492, 498-499 (1928).
We conclude that Mrs. Bryant failed to produce substantial evidence that the alleged negligence was the proximate cause of her damage and the judgment n. o. v. was properly granted for that additional reason.
Judgment affirmed.
LAY, Circuit Judge
(dissenting).
I respectfully dissent from the affirmance of the judgment n. o. v.
Although judges properly serve as an ultimate safeguard to prevent a miscarriage of justice and as such possess the legal authority to take away a jury’s finding of fact, nevertheless, the exercise of that power should be used only in exceptional circumstances. Unfortunately, this power is often exercised merely because judges sometimes feel that other results under the evidence are more reasonable than what the jury found. When this occurs we act without judicial authority. Tennant v. Peoria & Pekin Union Ry., 321 U.S. 29, 64 S.Ct. 409, 88 L.Ed. 520 (1944). Judges possess no expertise in evaluating facts or drawing inferences from the evidence. When as judges we act as fact finders we draw from our human experiences and biases just as jurors do. Yet when judges attempt to decide questions of reasonable care and causal connection, we more often fall short of the valued expertise of the jury. In resolving factual issues judges cannot possess the community values and judgment of a composite jury in attempting to equate conduct in terms of the common affairs of life. See Railroad Co. v. Stout, 84 U.S. 657, 664, 21 L.Ed. 745 (1873). When a judge holds that a jury’s verdict is wrong on a factual basis, he substitutes his reasonableness for that of twelve individuals who have resolved their subjective reasoning into an objective analysis and result.
