—In an action to recover damages for medical malpractice, the plaintiffs appeal from a judgment of the Supreme Court, Queens County (Satterfield, J.), entered June 23, 1994, which, upon a jury verdict in favor of the respondent and against them, dismissed the complaint.
Ordered that the judgment is reversed, on the law, the complaint is reinstated insofar as asserted against the respondent, and a new trial is granted, with costs to abide the event.
On or about November 19, 1979, the now-deceased Dr. Alexander DeLagarza performed a fistulectomy and sphincterotomy upon the plaintiff Mario Kasman, which allegedly rendered him incontinent. The plaintiffs commenced this action alleging, among other things, that Dr. DeLagarza was negligent in performing these procedures and performed them without informed consent. After a trial, the jury determined that Dr. DeLagarza was not negligent.
The plaintiffs contend that the trial court erred by unduly hampering their summation, by allowing the medical record of a nontestifying doctor, Dr. A.W. Martin Marino, to be received into evidence, and by granting the respondent’s request for a missing witness charge with regard to Dr. Marino. We agree with the plaintiffs’ contentions and conclude that a new trial is required.
At trial, certain of the medical insurance records of the plaintiff Mario Kasman were received into evidence. During the plaintiffs’ summation, the trial court prevented counsel from commenting on these records. It was prejudicial error to restrict the plaintiffs’ counsel from commenting within the four corners of the evidence during summation (see, Braun v Ahmed, 127 AD2d 418, 421-422, citing Williams v Brooklyn El. R. R. Co., 126 NY 96, 102-103).
The trial court also erred in permitting Dr. Marino’s report to be received into evidence when the respondent failed to offer foundational testimony pursuant to CPLR 4518 (a) or certify or authenticate it pursuant to CPLR 4518 (c) (see, Matter of Damon J., 144 AD2d 467; Diamond v Acker, 78 AD2d 546).
Under the circumstances, a new trial is required. O’Brien, J. P., Sullivan, Copertino and Joy, JJ., concur.
