Surgeons in Massachusetts have operated in the wrong location on patients 38 times since 2006, with botched spine surgeries accounting for more of the mistakes than any other type of operation, according to a review of state documents. New England Baptist accounted for four of the 11 bungled spine surgeries in the state. In three of the cases at the Baptist, surgeons discovered the error in the operating room and performed the correct procedure while the patient's spine was still exposed.
