Neurosurgeons and malpractice suits

We live in a litigious world. With respect to medicine, this manifests in medical malpractice suits. Patients sue doctors for unexpected adverse outcomes. One field prone to litigation is neurosurgery, which "treats acute pathology and refractory pain." Patient's dissatisfaction with the outcomes of neurosurgical procedures sometimes shifts over into the legal world where it forms the basis of medical malpractice suits.
