This handbook is a practical, easy-to-use reference that offers step-by-step instruction on ultrasound-guided interventional procedures for treatment of musculoskeletal pain of the lower limb. Each chapter is clearly structured and starts by offering a brief but comprehensive description of the disease to be treated that covers aspects such as epidemiology, etiology, clinical presentation and ultrasound diagnosis. The equipment and drugs needed for each interventional procedure are listed and the procedure itself is then described in detail. Explanatory images and easy-to-read schemes ensure that the reader will be able to follow procedures without difficulty, and helpful practical tips and tricks are highlighted for use in daily clinical routine. This is the sister volume to the previously published Ultrasound-Guided Musculoskeletal Procedures: The Upper Limb from the same editors.
