Ultrasonography can be highly useful in diagnosing and treating common musculoskeletal conditions affecting the foot and ankle, ranging from plantar fasciitis to osteoarthritis of the metatarsophalangeal joint of the great toe, as well as uncommon ones such as impingement of a tendon or nerve by fixation screw. One of the greatest advantages of ultrasonography is its high resolution for muscle, tendon, nerve, and bony surfaces and the opportunity to simultaneously identify, image, and evaluate tender structures. It can be used in a clinic setting and in the presence of metallic hardware. The short-axis injection approach is best for superficial, vertically oriented joints such as the cuneiform-metatarsal joints, whereas the long-axis approach is best for relatively deeper structures such as the tibiotalar joint and when it is important that the needle be visualized at all times, such as when performing a tibial nerve block.
