Effect of piriformis injection on neuropathic pain

Objectives: The aim of this study was to investigate the effect of a piriformis injection on neuropathic pain in patients with piriformis syndrome. Methods: Thirty patients with unilateral hip and/or leg pain, a positive FAIR test (increased H-reflex latency with Flexion, Adduction and Internal Rotation), and a trigger point at the piriformis muscle were enrolled in this prospective study. All of the patients exhibited neuropathic pain scored according to the Douleur Neuropathique 4 (DN4) of ≥4 for at least 6 months. All of the patients received 4 mL of lidocaine 2%+1 mL of betamethazone to the piriformis muscle under the guidance of ultrasound. The Numeric Rating Scale (NRS), DN4, and the painDETECT (PD) questionnaire were used for outcome assessment. Results: A statistically significant improvement was seen in all scores (p

Piriformis enjeksiyonunun nöropatik ağrı üzerine etkisi

Amaç: Piriformis sendromlu hastalarda uygulanan piriformis enjeksiyonunun hastalardaki nöropatik ağrı üzerine etkisini değerlendirmek. Gereç ve Yöntem: Tek taraflı kalça ve/veya bacak ağrısı olan, FAIR testi pozitif ve piriformis kasında palpasyonla tetik nokta saptanan 30 hasta çalışmaya dahil edildi. Bu prospektif çalışmada, tüm hastaların Douleur Neuropathique 4 (DN4) skoru en az 6 aydır 4 veya üzerinde idi. Tüm hastalara ultrason eşliğinde piriformis kasına 4 ml lidokain 2% + 1 ml betametazon enjekte edildi. Post-enjeksiyon 1. hafta ve 1. ayda hastalar değerlendirildi. Çalışmamızda, Numerik ağrı skalası (NAS), DN4, PainDETECT anketi (PDA) yöntemlerini kullandık. Bulgular: Başlangıç değerlerine göre 1. hafta ve 1. ay sonuçları karşılaştırıldığında tüm skorlarda istatistiksel olarak anlamlı düzelme olduğu görüldü (p
