Opinion
May 28, 1996
Appeal from the Supreme Court, Suffolk County (Gerard, J.).
Ordered that the order is affirmed, with one bill of costs payable to the respondents appearing separately and filing separate briefs.
The Supreme Court providently exercised its discretion in precluding, after the plaintiff's opening statement, the use of an expert due to the plaintiff's inability to show good cause for her failure to disclose in reasonable detail the subject matter on which the expert was expected to testify ( see, CPLR 3101 [d] [1] [i]). Since the plaintiff was unable to present expert opinion testimony to prove that the defendants' conduct constituted a deviation from the requisite standard of care, she was unable to make out a prima facie case and the respective motions to dismiss the complaint were properly granted ( see, Mankowski v. Two Park Co., 225 A.D.2d 673; Kalkan v. Nyack Hosp., 214 A.D.2d 538; Lasek v. Nachtigall, 189 A.D.2d 749). Balletta, J.P., Miller, Sullivan and Pizzuto, JJ., concur.
