Abstract
Management of a case of ankylosing spondylitis can be very challenging when the airway and the central neuraxial blockade, both are difficult. Ultrasound-assisted central neuraxial blockade may lead to predictable success in the field of regional anaesthesia. We present a young patient with severe ankylosing spondylitis where conventional techniques failed and ultrasound helped in successful combined spinal-epidural technique for total hip replacement surgery.
