Study design: A case report defining an interventional procedure. Objectives: To reveal the role of the ultrasonography in nerve blocks at difficult anatomical locations of the obturator nerve. Setting: The study was conducted in Ankara, Turkey. Methods: A paraplegic patient with lower limb adductor spasticity treated with phenol block using the guidance of ultrasonography. Results: After treatment of the adductor spasticity by obturator nerve block the patient achieved an upright standing position with a walker. Hygienic care was improved and spasticity-related pain was reduced. Conclusion: Ultrasound is a challenging tool for nerve blocks. Ultrasound guidance seems as an essential approach for the blocking of the nerves with variable anatomical courses, such as the obturator nerve.
