ATLANTA - A trial court erred in excluding expert testimony that an obstetrician violated the standard of care when she perforated a woman's uterus and bowel during a procedure, a Third Division Georgia Court of Appeals panel held Nov. 20 in a medical malpractice action (Emma Cartledge v. Jolene Montano, et al., No. A13A1580, Ga. App., Div. III; 2013 Ga. App. LEXIS 958).
