Abstract

Apparatus and method to induce osteogenesis in a bone region of a patient, by which at least one beam of ultrasounds is generated, focused and directed toward a bone region of a patient, such that the beam focus is matched with a specific point of the bone region. The ultrasound beam hits the bone region with an intensity and for a duration such to cause a hematoma and/or local inflammation and/or a series of micro-fractures in the target bone region, thereby activating a mechanism of osteogenesis.

Claims

1. A method of inducing osteogenesis in a bone region of a patient comprising:

producing at least one beam of ultrasounds;

focusing the at least one beam of ultrasounds;

directing the at least one beam of ultrasounds to the bone region of the patient, causing the focus of the at least one beam of ultrasounds to coincide with a predetermined point of the bone region;

wherein power and duration of the at least one beam of ultrasounds on the bone region are selected to cause, in an area of the bone region, a hematoma and/or a local inflammation and/or a series of micro-fractures, next to which an osteogenetic mechanism will be activated.

2. The method according to claim 1, wherein the at least one beam comprises two beams focused to converge into the predetermined point of the bone region.

3. The method according to claim 1, further comprising subjecting the bone region to a radioscopy, the result of the radioscopy being displayed by a video terminal connected to a computerized unit supplied with references, such that the computerized unit determines coordinates of every point visualized by the radioscopy, and such that a position of the focus of the at least one beam of ultrasounds is clearly identified and displayed in the video terminal over predetermined time intervals.

4. The method according to claim 1, further comprising exploring the bone region with magnetic resonance imaging, a result of the exploration being displayed by a video terminal connected to a computerized unit supplied with references, such that the computerized unit determines coordinates of every displayed point, and such that a position of the focus of the at least one beam of ultrasounds is clearly identified and visualized in the video terminal over predetermined time intervals.

5. The according to claim 1, further comprising the step of enabling an operator to modify a position of the focus of the at least one beam of ultrasounds to match the focus with the predetermined point of the bone region.

6. The method according to claim 5, wherein the operator is enabled to modify a direction of spreading of the at least one beam of ultrasounds by operating a joystick connected to a computerized unit.

14. The method according to claim 1, wherein the bone region is a neck of the femur.

7. Equipment to induce osteogenesis in a bone region of a patient, comprising:

an emitter configured to generate at least one focused beam of ultrasounds and to direct the at least one focused beam of ultrasounds to the bone region, the emitter providing the focus of the at least one beam at a predetermined point of the bone region,

wherein power and duration of the at least one focused beam on the bone region are selected to cause a hematoma and/or a local inflammation and/or a series of micro-fractures, next to which an osteogenetic mechanism will be activated.

8. The equipment according to claim 7, further comprising a power system configured to modify a direction of spreading of the at least one focused beam of ultrasounds.

9. The equipment according to claim 7, wherein there are two focused beams of ultrasounds.

10. The equipment according to claim 7 further comprising a computerized unit to which a video terminal is connected, wherein the bone region is subjected to radioscopy and the result of the radioscopy is displayed by the video terminal, together with references, such that the computerized unit identifies coordinates of every point displayed through the radioscopy, and such that a position of the focus of the at least one focused beam of ultrasounds is clearly identified and displayed on the video terminal over predetermined time intervals.

11. The equipment according to claim 7, further comprising a computerized unit to which a video terminal is connected, wherein the bone region is explored by magnetic resonance imaging, such that a result of the exploration is displayed by the video terminal together with references, such that the computerized unit determines coordinates of every displayed point, and such that a position of the focus of the at least one focused beam of ultrasounds is clearly identified and displayed on the video terminal.

12. The equipment according to the claim 7, further comprising a control unit configured to modify, in use, a position of the focus of the at least one focused beam of ultrasounds and to direct the at least one focused beam of ultrasounds over the predetermined point of the bone region.

13. The equipment according to the claim 12, wherein the control unit comprises a joystick movable by an operator and connected to a computerized unit operatively coupled to imaging equipment and wherein the imaging equipment provides one or more images of the bone region on a video terminal together with references, such that the computerized unit determines coordinates of every displayed point, and such that a position of the focus of the at least one focused beam of ultrasounds is clearly identified and displayed on the video terminal.

15. The equipment according to claim 7, wherein the bone region is the neck of the femur.
