OPINION OF THE COURT
In this medical malpractice case we consider primarily the problem of distinguishing the effect of the defendant Dr. Harold R. Weichert’s alleged negligence from the natural results of plaintiff William F. Monahan’s disease. Trial Term dismissed the complaint against Dr. Weichert at the end of the plaintiff’s case concluding that there was insufficient evidence to permit the inference of proximate cause, i.e., any causal connection between defendant doctor’s conduct and plaintiff’s injury. We reverse and grant a new trial. The proof of proximate cause sufficiently raised issues for determination by the jury.
Plaintiff, who since 1962 had a history of rheumatoid arthritis in a number of joints throughout his body, received medical treatment over the years, consisting of aspirations (removal of fluid from the knees), gold injections and dosages of aspirin and cortisone. Synovectomy operations (removal of the lining of the knee joint, menisci and bony spurs from within the joint) were performed on both knees. To alleviate pain suffered by plaintiff due to his arthritic condition, defendant performed hip operations on plaintiff between 1969 and 1972 which involved installation of prostheses in both his right and left sides. During this time plaintiff used a cane constantly because of the pain in his legs and knees associated with his arthritis. Defendant continued treating plaintiff with the use of periodic aspira
Defendant performed a supracondylar femoral wedge osteotomy on plaintiff’s left leg on July 27, 1972 and on the right leg on August 3, 1972. These operations were designed to correct the knee flexion contractures by removing a piece of bone from the femur just above the knee and artificially joining the femur with a plate and screws to form a compensating angle to permit knee flexation. Following surgery plaintiff’s legs were placed in plaster casts. When the casts were, removed five weeks later plaintiff’s legs were stiff and he never regained mobility in either knee despite recommended physiotherapy. Before the 1972 operations Dr. Weichert described plaintiff as suffering from ankylosis or stiffening of the knee joint. In his deposition Dr. Weichert testified that he anticipated that plaintiff, after the surgical intervention, would regain some motion following a course of physiotherapy but that postoperative stiffness is a possibility in any rheumatoid arthritic patient.
Plaintiff offered expert testimony that he has completely ankylosed knees fused between 25 and 30 degrees of flexion, that the condition is permanent and that no further treatment is indicated. Plaintiff’s medical expert testified as to pre- and postoperative treatment which, in his opinion, constituted deviations from the acceptable standards of
Plaintiff claims that' the trial court misinterpreted the testimony of his expert on the issue of proximate cause to mean that it was conjecture whether Dr. Weichert’s negligence caused the injury. Defendant, on the other hand, claims that the dismissal was proper since the testimony of plaintiff’s own expert failed to establish that plaintiff’s injuries resulted from the surgery and that there was insufficient evidence to permit the inference of proximate cause.
In reviewing the dismissal of plaintiff’s complaint at the close of his case, the test is whether “there was any rational basis on which a jury could have found for [plaintiff] ” (Rhabb v New York City Housing Auth.,
In addition, however, plaintiff must establish that the injuries sustained were caused by the doctor’s failure to exercise reasonable care (Koehler v Schwartz,
Causation incorporates at least two separate but related concepts: cause-in-fact and proximate cause. Cause-in-fact refers to those antecedent events, acts or omissions which have “so far contributed to the result that without them it would not have occurred.” (Prosser, Torts [4th ed], § 41, p 237; see Koehler v Schwartz, supra, p 809.) Ordinarily, this requirement is satisfied if the given act or omission was a substantial factor in producing the resultant injury (Dunham v Village of Canisteo,
Proximate cause, a troublesome concept of the law of negligence generally, poses special problems in the field of medical malpractice. The problem is described in one treatise as follows: “Almost every person who receives the services of a physician is sick or disabled when he first goes to the physician. Thus there lurks the ever present possibility that it was the patient’s original affliction rather than the physician’s negligence which caused the ultimate damage.” (1 Louisell and Williams, Medical Malpractice, par 8.07, p 213.)
Ordinarily, expert medical opinion testimony is required to establish proximate cause and make out a prima facie case of medical malpractice unless the causal relationship is readily apparent to the trier of fact (Hammer v Rosen, 7 NY2d 376; Zettler v Reich,
The precise issue in this case is whether plaintiff’s proof on the issue of proximate cause was sufficient as a matter of law to create a question of fact for the jury. “Proximate cause presents a question of fact for the jury ‘if varying inferences are possible’ and is ‘always dependent upon the facts of a particular case, and it is for this reason that the words are beyond definition or conclusive explanation’ (O’Neill v. City of Port Jervis,
The trial court also dismissed plaintiff’s second cause of action for lack of informed consent against Dr. Weichert. This ruling, based on a failure to establish defendant’s
The trial court was correct, however, in dismissing plaintiff’s action against defendant hospital, since there was no expert medical testimony establishing a causal link between the hospital’s alleged failure to keep proper medical records on plaintiff and plaintiff’s injuries. Although plaintiff’s expert witness testified that the hospital’s records were inadequate, he was unable to formulate an opinion as to whether this was causal to plaintiff’s injury.
It is unnecessary to pass on other issues raised on this appeal.
Accordingly, the judgment dismissing the complaint against the defendant Dr. Weichert should be reversed and a new trial granted. The judgment dismissing the complaint against the defendant hospital should be affirmed.
