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.

Claims

1. 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.

2. 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.

3. Method for medical treatment of bone pathology according to to claim 2, wherein the impact waves acting on the pathological site are electrohydraulic.

4. Method for the medical treatment of bone pathology according to claim 1, wherein the bone is fixed with an extrafocal fixator and the pathological site is subjected to the action of impact waves of from 1000 to 6000 impacts with a frequency of from 1 to 3 per second at a pressure of from 1100 to 1700 bars and pulse duration of from 1 to 3.5 microseconds over 30 to 115 minutes with a subsequent immobilization for a period of from 60 to 85 days.

5. Method for medical treatment of bone pathology according to claim 1, wherein the pathological site is subjected to the action of impact waves of from 750 to 6000 impacts with a frequency of from 0.5 to 3.5 per second at a pressure of from 1200 to 2500 bars and pulse duration of from 0.5 to 2.5 microseconds over 15 to 120 minutes with a subsequent immobilization for a period of from 30 to to 80 days.

6. Method for medical treatment of bone pathology according to claim 1, wherein the pathological site is subjected to the action of impact waves of from 300 to 3000 impacts with a frequency of from 1 to 3.5 per second at a pressure of from 700 to 1500 bars and pulse duration of from 1.5 to 4 microseconds during 10 to 90 minutes, with a subsequent immobilization for a period of from 15 to 60 days.

7. Method for medical treatment of bone pathology according to claim 1, wherein the pathological site is subjected to the action of impact waves of from 500 to 5000 impacts with a frequency of from 0.5 to 4 per second, at a pressure of from 850 to 1700 bars and pulse duration of from 1.5 to 3.5 microseconds over 15 to 95 minutes, with a subsequent immobilization on for a period of from 15 to 60 days.

8. Method for medical treatment of bone pathology according to claim 1, wherein the pathological site is subjected to the action of impact waves of from 1000 to 5500 impacts with a frequency of from 1 to 4 per second, at a pressure of from 950 to 1900 bars and pulse duration of from 0.5 to 3.5 microseconds over 20 to 110 minutes, with a subsequent immobilization for a period of from 15 to 90 days.

9. Method for medical treatment of bone pathology according to claim 1, wherein the pathological site is subjected to the action of impact waves of from 350 to 4000 impacts with a frequency of from 1 to 2.5 per second at a pressure of from 150 to 1600 bars and pulse duration of from 1.5 to 3 microseconds over 10 to 105 minutes, with a subsequent immobilization for a period of from 15 to 30 days.
