text: So far, mainly three uses have been proposed for shock waves in clinical orthopedics: (a) to cause microfractures of cortical bone used to perform closed osteotomies or to stimulate local hematoma formation and bone healing at the site of nonunion; (b) to fragment polymethylmethacrylate (PMMA) cement and separate it from bone; and (c) to bring relief to patients suffering from pain due to chronic chalk shoulder, heel spur, or tennis elbow.
