Popis
Inclusion Criteria:
- Objective clinical diagnosis of unilateral piriformis syndrome for at least 3 months (as assessed by Clinical Scoring System for the Diagnosis of Piriformis Muscle Syndrome: score of 8 or greater
- Absence of herniated lumbar disc which can explain radiating pain (MRI or computed tomography (CT) of the lumbar spine)
- Patients not responding to conventional care (physiotherapy, muscle relaxants, analgesics)
- Baseline sciatic pain intensity of at least 4 points on visual analog scale
- Provision of written informed consent
- Patients affiliated to social security system (health insurance coverage).
Exclusion Criteria:
- Bilateral piriformis muscle syndrome.
- History of piriformis syndrome surgery.
- History of botulinum toxin administration.
- Any treatment (general or local) likely to interfere with botulinum toxin or evaluation of the primary endpoint (Corticosteroids, aminoglycosides).
- Corticosteroids in the past 3 weeks.
- Signs of severe fibrosis (on MRI or CT) of the piriformis muscle.
- Other causes of sciatic pain (lumbar root compression, inflammatory, infectious or neoplasic pelvic disease, particularly for inflammatory sacroiliac pain).
- Hip prosthesis on the same side as piriformis syndrome; knee prosthesis is tolerated.
- Contraindication to BT injection:
- History of intolerance, hypersensitivity or known allergy to any botulinum toxin product or excipients;
- Patients with myasthenia gravis or other diseases of the neuromuscular junction;
- Patients with Lambert-Eaton Syndrome;
- Patients with neurological disorders such as dysphagia, swallowing disorders or aspiration pneumonia;
- Current infection at the proposed injection site;
- Long-term anticoagulant therapy ;
- Antibiotics and vaccination are prohibited for 15 days before and after BT injection
- Pregnant or breastfeeding women. Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant must use an effective method of contraception (oral contraceptives, contraceptive injections, intrauterine devices, method of double-barrier contraceptive patches). The contraception should be maintained throughout the study.

- Inability to understand the reasons for the study; psychiatric disorders judged by the investigator to be incompatible with inclusion in the study.
- Patients with legal disability or limited legal capacity.
