Hip joint method
A method of treating a hip joint of a human patient is disclosed. The method comprises the steps of: inserting a needle or a tube like instrument into the patient's body, using the needle or tube like instrument to fill a part of the patient's body with gas and thereby expanding a cavity within said body, placing at least two laparoscopic/arthroscopic trocars in said cavity, inserting a camera through one of the laparoscopic/arthroscopic trocars into said cavity, inserting at least one dissecting tool through one of said at least two laparoscopic/arthroscopic trocars, dissecting an area of the pelvic bone on the opposite side from the acetabulum, creating a hole in said dissected area, said hole passing through the pelvic bone and into said hip joint of the patient, and providing said medical device to the hip joint, through said hole in the pelvic bone of the patient.
1. A method of treating a hip joint of a human patient by providing a medical device comprising at least one partly ball or bowl shaped artificial hip joint surface adapted to replace at least one hip joint surface in a functional hip joint, said hip joint comprising a caput femur and an acetabulum, said method comprising the steps of:
inserting a needle or a tube like instrument into the patient's body,
using the needle or tube like instrument to fill a part of the patient's body with gas and thereby expanding a cavity within said body,
placing at least two laparoscopic/arthroscopic trocars in said cavity,
inserting a camera through one of the laparoscopic/arthroscopic trocars into said cavity,
inserting at least one dissecting tool through one of said at least two laparoscopic/arthroscopic trocars,
dissecting an area of the pelvic bone on the opposite side from the acetabulum,
creating a hole in said dissected area, said hole passing through the pelvic bone and into said hip joint of the patient, and
providing said medical device to the hip joint, through said hole in the pelvic bone of the patient.
2. The method according to claim 1 , wherein said medical device comprising an artificial caput femur.
3. The method according to claim 1 , further comprising the step of reaming the caput femur.
4. The method according to claim 1 , further comprising the step of fixating said hip joint surface to the caput femur or to the acetabulum.
5. The method of treating a hip joint of a human patient according to claim 4 , wherein said fixation is performed by means of mechanical fixating members, bone cement or adhesive.
6. The method according to claim 1 , further comprising the step of closing said hole.
7. The method according to claim 6 , wherein said hole is placed in the pelvic bone, wherein said closing of said hole in the pelvic bone is performed by means of a prosthetic part.
8. The method according to claim 1 , further comprising the step of placing a mould inside of the hip joint.
9. The method according to claim 8 , further comprising the step of injecting a fluid into said mould placed inside of the hip joint of the human patient.
10. The method according to claim 1 , further comprising the steps of:
placing at least one sealing member between the acetabulum and the caput femur, thus creating a sealed area between the acetabulum and the caput femur, and
injecting a fluid into said sealed area.
11. A method of treating a hip joint of a human patient by providing a medical device comprising at least one partly ball or bowl shaped artificial hip joint surface adapted to replace at least one hip joint surface in a functional hip joint, said hip joint comprising a caput femur and an acetabulum, said method comprising the steps of:
cutting the skin of the patient,
dissecting an area of the pelvic bone on the opposite side from the acetabulum,
creating a hole in said dissected area, said hole passing through the pelvic bone and into the hip joint of the patient, and
providing said medical device to the hip joint, through said hole in the pelvic bone of the patient,
wherein said medical device comprises an artificial caput femur.
12. The method according to claim 11 , further comprising the step of reaming the caput femur.
13. The method according to claim 11 , further comprising the step of fixating said hip joint surface to the caput femur or to the acetabulum.
14. The method of treating a hip joint of a human patient according to claim 13 , wherein said fixation is performed by means of mechanical fixating members, bone cement or adhesive.
15. The method according to claim 11 , further comprising the step of closing said hole.
16. The method according to claim 15 , wherein said hole is placed in the pelvic bone, wherein said closing of said hole in the pelvic bone is performed by means of a prosthetic part.
17. The method according to claim 11 , further comprising the step of placing a mould inside of the hip joint.
18. The method according to claim 17 , further comprising the step of injecting a fluid into said mould placed inside of the hip joint of the human patient.
19. The method according to claim 11 , further comprising the steps of:
placing at least one sealing member between the acetabulum and the caput femur, thus creating a sealed area between the acetabulum and the caput femur, and
injecting a fluid into said sealed area.
