Ultrasound-guided piriformis injection: technique description and verification.
Piriformis injections are commonly used in the evaluation and treatment of patients presenting with buttock pain syndromes. Because of its small size, deep location, and relation to adjacent neurovascular structures, the piriformis is traditionally injected by using electromyographic, fluoroscopic, computed tomographic, or magnetic resonance imaging guidance. This report describes and verifies a technique for performing ultrasound-guided piriformis injections. Ultrasound offers several advantages over traditional imaging approaches, including accessibility, compact size, lack of ionizing radiation exposure, and direct visualization of neurovascular structures. With appropriate training and experience, interested physiatrists can consider implementing ultrasound-guided piriformis injections into their clinical practices.

"Broken heart syndrome" after separation (from OxyContin).
We describe a 61-year-old woman with "broken heart syndrome" (Takotsubo-like cardiomyopathy) after abrupt postsurgical withdrawal of OxyContin. Her medical history was remarkable for long-term opiold dependence associated with the treatment of multi-Joint degenerative osteoarthritis. The patient presented to the emergency department 1 day after discharge from the hospital following total knee arthroplasty revision with acute-onset dyspnea and mild chest pain. She had precordial ST-segment elevation characteristic of acute myocardial infarction and elevated cardiac biomarkers. Emergency coronary angiography revealed no major coronary atherosclerosis. However, the left ventricular ejection fraction was severely decreased (26%), and new regional wall motion abnormalities typical of broken heart syndrome were noted. In addition to resuming her opioid therapy, she was treated supportively with bilevel positive airway pressure, diuretic therapy, morphine, aspirin, metoprolol, enalaprilat, intravenous heparin, nitroglycerin infusion, and dopamine infusion. Ventricular systolic function recovered completely by the fourth hospital day. To our knowledge, broken heart syndrome after opioid withdrawal has not been reported previously in an adult. Our case illustrates the importance of continuing adequate opiate therapy perioperatively in the increasing number of opioid-dependent patients to prevent potentially life-threatening complications such as broken heart syndrome.
