Teacher: Now, understand the problem? Solve this instance: Question: Does regional anesthesia improve outcome in patients undergoing proximal humerus fracture repair?
Answer: Patients who received regional anesthetic via a brachial plexus interscalene blocks had better functional outcomes and range of motion at the most recent clinical follow-up. Regional anesthesia provides patients with prolonged postoperative pain relief, which may allow for early mobilization, increasing the likelihood that the patient's function and range of motion will return to baseline.
