Ultrasound-guided injection of botulinum toxin A (BTX-A) in spastic iliopsoas treatment

Purpose: Intramuscular injection of botulinum toxin A is a common treatment of spastic iliopsoas muscle but it is not easy to position the needle in the muscle without a guidance. Therefore, the purpose of our work is to describe an ultrasound-guided technique for the intramuscular injection of BTX-A to treat the spasticity of iliopsoas muscle and to assess the effectiveness of this therapy. Materials and methods: We treated 10 patients with this ultrasound-guided injection technique of BTX-A. The needle is inserted in the muscle belly with an angle of 45° on the longitudinal axis of the muscle itself. Results:…
