On a motion for summary judgment dismissing a cause of action alleging medical malpractice, the defendant bears the initial burden of establishing that there was no departure from good and accepted medical practice, or that any alleged departure did not proximately cause the plaintiff's injuries. If the defendant makes this showing, the burden shifts to the plaintiff to raise a triable issue of fact as to those elements on which the defendant met its prima facie burden. Summary judgment is not appropriate in a medical malpractice action where the parties put forward conflicting medical expert opinions. However, expert opinions that are conclusory, speculative, or unsupported by the record are insufficient to raise triable issues of fact.
