Abstract
Abstract A method is disclosed for medically treating a patient suffering from a pathological bone condition of a limb, which comprises the steps of: anesthetizing the patient; fixing the limb affected with the pathological bone condition and centering its pathological site; treating the pathological site, once, consecutively, and extracorporeally with impact waves of from 300 to 600 impacts with a frequency of impacts of from 0.5 to 4 per second at a pressure of from 700 to 2500 bars and a pulse duration of from 0.5 to 4 microseconds for a period of 10 to 120 minutes; and subsequently immobilizing the limb for a period of from 15 to 90 days.

Claim 1
Independent Claim
112 words
A method of medically treating a patient suffering from a pathological bone condition of a limb, which comprises the steps of: (a) anesthetizing the patient; (b) fixing the limb affected with the pathological bone condition and centering its pathological site; (c) treating the pathological site, once, consecutively, and extracorporeally with impact waves of from 300 to 6000 impacts with a frequency of impacts of from 0.5 to 4 per second at a pressure of from 700 to 2500 bars and a pulse duration of from 0.5 to 4 microseconds for a period of 10 to 120 minutes; and (d) subsequently immobilizing the limb for a period of from 15 to 90 days.
Claim 2
Independent Claim
112 words
A method of medically treating a patient suffering from a pathological bone condition of a limb, which comprises the steps of: (a) anesthetizing the patient; (b) fixing the limb affected with the pathological bone condition and centering its pathological site; (c) treating the pathological site, once, consecutively, and extracorporeally with impact waves of from 300 to 6000 impacts with a frequency of impacts of from 0.5 to 4 per second at a pressure of from 700 to 2500 bars and a pulse duration of from 0.5 to 4 microseconds for a period of 10 to 120 minutes; and (d) subsequently immobilizing the limb for a period of from 15 to 90 days.
Claim 3
Dependent Claim
75 words
Method for medical treatment of bone pathology according to claim 1, wherein the treatment of the pathological site is effected by impact waves of from 1000 to 5000 impacts with a frequency of from 1 to 2 per second at a pressure of from 1200 to 2000 bars, and pulse duration of from 1.5 to 3 microseconds over 20 to 110 minutes, with a subsequent immobilization for a period of from 40 to 90 days.
