Practice point: If the matter is not within the ordinary juror's experience, expert testimony is needed to prove a deviation from the accepted standard of medical care and proximate cause.
Student note: When that expert testimony is precluded, plaintiff cannot make out a prima facie case, and the complaint will be dismissed.
