Ultrasound-Guided Injection Can Benefit Lateral Hip Pain
Small study shows ultrasound-guided corticosteroid injection has high success rate
TUESDAY, Dec. 29 (HealthDay News) -- In patients with gluteus medius tendinopathy, peritendinous ultrasound-guided corticosteroid injection may be an effective treatment, according to a study published in the January issue of the American Journal of Roentgenology.
Julie M. Labrosse, of the Centre Hospitalier de l'Université de Montréal, and colleagues studied 54 patients (mean age, 54.7 years) who underwent a hip ultrasound followed by a gluteus medius peritendinous ultrasound-guided injection of 30 mg of triamcinolone combined with 3 mL of bupivacaine 0.5 percent using an anterior oblique coronal plane.
After one month, the researchers observed a clinically significant improvement in pain level -- defined as a reduction in the visual analog scale pain score of at least 30 percent -- in 72 percent of the patients. They also found that 70 percent of patients reported satisfaction with the procedure.
"Advantages of ultrasound over fluoroscopy include its soft-tissue imaging capabilities that allow a diagnostic study to be performed before cortisone injection," the authors write. "Ultrasound also permits continuous real-time monitoring of the needle position relative to the targeted distal gluteus medius tendon."
