Nerve injury represents the most common reason for medical malpractice litigation following THA (38%). Medical malpractice in the United States involves proving that the healthcare provider owed a duty to the patient, that there was negligence committed (a deviation from the accepted standard of care), that the patient suffered damages, and that this negligence directly caused these damages to the patient. Malpractice litigation following THA is most commonly the result of nerve injury (38%) with the second most common cause being limb length inequality (26%). Dislocation has not been reported as a cause of litigation. Samuel et al review medical malpractice litigation following primary total joint arthroplasty. They report that infection was the most common cause for litigation in TKA, while nerve injury was most common following THA. They conclude that surgeons should be cognizant of the potential for lawsuit due to these complications and should ensure they inform patients of these potential complications of preoperatively. Bokshan et al review reported on litigation associated with primary hip and knee arthroplasty. They report that 15.0% of cases ended in settlement and 29.6% ended in a verdict in favor of the plaintiff (physician loss). They conclude that objective technical complications or nerve injuries were associated with an increased risk of a physician loss and a higher payment following litigation. Incorrect Answers: Answer 1: The worst prognosis is seen in patients with complete motor and sensory deficits. Answer 2: Peroneal division of the sciatic nerve is most commonly affected. Answer 3: While the superior gluteal, obturator, and femoral nerves may be injured, the sciatic is the most common. Answer 4: Only 30-40% of patients with a complete sciatic nerve palsy will recovery full strength.
