Background
Alma Johnson alleged that surgeons at Montefiore Medical Center injured her ureter while performing a hysterectomy to remove a cancerous tumor. She claimed that the doctors should have inserted protective ureteral catheters, created tunnels around the ureters, avoided the injury, and performed a postoperative cystoscopy. The defendants maintained that ureteral injury was a known surgical risk, that they followed accepted practice, and that Johnson's later presentation did not establish a negligent delay in diagnosis.
The defendants moved for summary judgment with medical records, deposition testimony, and expert affirmations. Johnson opposed with her own expert and separately sought dismissal of a culpable-conduct affirmative defense. Supreme Court dismissed the challenged malpractice theories and retained the defense. The First Department considered whether Johnson's expert identified a supported departure and responded to the particular causal mechanism described by the defense experts.
The Court’s Holding
The First Department affirmed dismissal. The defense submissions established that the operation was performed within accepted practice and offered a specific explanation for the injury: devascularization could damage the ureter over time without producing an injury visible during the procedure. The defense expert connected that mechanism to Johnson's postoperative clinical course. That showing shifted the burden to Johnson to identify a genuine medical dispute on both departure and causation.
Johnson's expert did not adequately meet that burden. The opinion did not answer the devascularization explanation or explain why the injury should have been apparent during surgery despite that mechanism. Failure to address a material defense expert opinion was fatal to the opposition. The panel also rejected the challenge to reliance on testimony about the surgeon's customary practice and held that the culpable-conduct defense remained under the law of the case based on an earlier appeal.
Key Takeaways
- A malpractice expert opposing summary judgment must directly address the defense's specific causation theory, not merely repeat a competing negligence conclusion.
- When the defense explains why an injury would not have been visible during surgery, silence on that point can be fatal.
- An issue resolved on an earlier appeal ordinarily remains law of the case in later stages of the same action.
Why It Matters
For New York malpractice counsel, Johnson underscores that expert affirmations should be built as point-by-point responses. The opposing expert must review the full defense submission and explain why each material mechanism is medically incorrect, unsupported, or irrelevant. A lengthy affirmation can still fail if it leaves the dispositive causal explanation unanswered. Counsel should use a comparison chart before filing to ensure that every claimed departure and causation proposition receives a supported response.
Hospitals and physicians can use the decision as a model for a focused summary-judgment record. A defense opinion is most effective when it goes beyond saying that care was appropriate and explains how the injury could occur without negligence, why it would not have been discoverable earlier, and how the records fit that account. Plaintiffs should preserve responsive imaging, operative details, pathology, and expert reasoning rather than rely on the occurrence of a recognized complication itself.
The retained culpable-conduct defense illustrates another procedural lesson. Once an appellate court has decided an issue in the same action, later motion practice generally cannot relitigate it simply with a reformulated argument. Counsel should track prior appellate holdings in a case chart and identify which issues remain genuinely open. At the expert stage, physicians should supply the factual and medical foundation for custom-and-practice testimony, while opponents should preserve objections in Supreme Court rather than first raising them on appeal. These disciplines matter because malpractice appeals often turn less on broad medical disagreement than on whether a precise objection or causal response was preserved and supported at the summary-judgment stage.
