Abstract

A method of treating pathological conditions associated with bone and soft tissue adjacent to musculoskeletal environments and soft tissues and osteoporotic sites and of enhancing bone formation and remodeling in a stress fracture, involves applying acoustic shock waves to cause localized trauma, including micro-disruptions, non-osseous tissue stimulation, injury and increased vascularization, and circulation and induction of growth factors to induce or accelerate the body'"'"'s natural healing processes and responses thereby inducing or accelerating healing.

Claims

1. A method of treating a pathological condition associated with a bone lengthening procedure in a human or animal comprising:

locating a site or suspected site of the pathological condition;

generating acoustic shock waves and coupling to a body with a therapy head;

focusing the acoustic shock waves on the located site within a focal volume of applied shock waves aligned with the site, wherein the focal volume includes a pressure highest at the focal center and pressure decreasing with increasing distance from the focal center; and

applying a sufficient number of acoustic shock waves within approximately 20 to 150 minutes to apply a total energy applied to the located site per treatment of about 28,000 to about 140,000 mJ to induce micro-injury and increased vascularization thereby accelerating vascular ingrowth and remodeling in the bone lengthening procedure.

2. The method of claim 1, wherein applying a sufficient number of acoustic shock waves comprises applying about 1000 to about 5000 acoustic shock waves per treatment.

3. A method of treating an osteoporotic site in an animal or human comprising:

locating an osteoporotic site or suspected osteoporotic site;

generating acoustic shock waves;

focusing a sufficient number of acoustic shock waves from a therapy head to the located site within a focal volume of applied shock waves aligned with the site wherein the focal volume includes a pressure highest at the focal center and pressure decreasing with increasing distance from the focal center, and said focusing is within approximately 30 minutes to 1.5 hours to induce micro-injury and increased vascularization thereby inducing or accelerating healing, wherein a total energy applied to the located site per treatment is about 28,000 to about 140,000 mJ.

4. The method of claim 3, wherein the located site is an osteoporotic wrist and applying a sufficient number of acoustic shock waves comprises applying about 800 to about 4000 acoustic shock waves per treatment.

5. The method of claim 3, wherein the located site is an osteoporotic hip and applying a sufficient number of acoustic shock waves comprises applying from about 800 to about 8,000 acoustic shock waves per treatment.

6. A method to enhance bone formation and remodeling in a stress fracture of a human or animal comprising:

locating a site or suspected site of a pathological condition associated with the stress fracture;

generating acoustic shock waves;

focusing the acoustic shock waves on the located site within a focal volume of applied shock waves aligned with the site, wherein the focal volume includes a pressure highest at the focal center and pressure decreasing with increasing distance from the focal center; and

applying a sufficient number of acoustic shock waves to the located site within approximately 45 minutes to 2 hours to induce micro-injury and increased vascularization thereby inducing or accelerating healing, wherein a total energy applied to the located site per treatment is about 28,000 to about 140,000 mJ.

7. A method to enhance bone formation and remodeling in a stress fracture of a human or animal comprising:

locating a site or suspected site of a pathological condition associated with the stress fracture;

generating acoustic shock waves;

focusing the acoustic shock waves on the located site within a focal volume of applied shock waves aligned with the site, wherein the focal volume includes a pressure highest at the focal center and pressure decreasing with increasing distance from the focal center; and

applying a sufficient number of acoustic shock waves to the located site within approximately 45 minutes to 2 hours to induce micro-injury and increased vascularization thereby inducing or accelerating healing, wherein a total energy applied to the located site per treatment is about 28,000 to about 140,000 mJ, wherein applying a sufficient number of acoustic shock waves comprises about 1000 to about 8000 acoustic shock waves per treatment.
