Piriformis syndrome involves the irritation of the piriformis muscle due to various reasons that are primarily related to anatomical variation or sciatic nerve compression due to contraction caused by overuse. In this study, we aimed to define an injection method that is easy to apply, safe, simple and repeatable. ⋯ Our findings lead to the conclusion that fluoroscopy-guided percutaneous local anaesthetic and corticosteroid injection is a simple and effective piriformis syndrome treatment that can feasibly be effectively performed by orthopaedic surgeons.

Comparative Study
Lesion of gluteal nerves and muscles in total hip arthroplasty through 3 surgical approaches. An electromyographically controlled study.
Three surgical approaches in total hip arthroplasty (THA) were compared concerning: 1) clinical and radiological results; 2) innervation of the tensor fasciae latae and gluteal muscles; 3) clinical outcome of the nerve lesions; 4) sensitivity of the EMG analysis. ⋯ Despite some disadvantages associated with the anterolateral approach, the transgluteal and posterior approaches are often connected with a partial lesion of the gluteus medius and maximus muscles. In all approaches, clinical sequelae are not significant in primary THA.
