Abstract

The present invention relates to a method of treating a hip joint of a human patient, the hip joint comprising an acetabulum, the acetabulum being a part of the pelvic bone, and a caput femur, the caput femur being the proximal part of the femoral bone, said method comprising the steps of: cutting the skin of the human 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 human patient, and performing an action in the hip joint, through said hole in the pelvic bone.

First claim

The invention claimed is:

1. A method of treating a hip joint of a human patient, the hip joint comprising an acetabulum, the acetabulum being a part of the pelvic bone, and a caput femur, the caput femur being the proximal part of the femoral bone, said method comprising the steps of:
cutting the skin of the human patient,
dissecting an area of the pelvic bone on an abdominal side of the pelvic bone,
creating a hole in said dissected area, said hole passing through the pelvic bone from the abdominal side and into the hip joint of the human patient, and
further comprising at least one of the steps selected from the group consisting of:
placing or fixating fixation elements to the pelvic bone or to a prosthetic part in the hip joint,
fixating an artificial hip joint surface, or a part of an artificial hip joint surface, to the pelvic bone or the femoral bone,
connecting at least two prosthetic parts to each other after insertion into the hip joint, and
introducing a prosthesis into the hip joint,
wherein said at least one step is conducted through said hole in the pelvic bone.

2. The method according to claim 1 , wherein the step of placing or fixating fixation elements to the pelvic bone or to a prosthetic part in the hip joint is performed using a surgical instrument adapted to assist in operating in the hip joint from the abdominal side of the pelvic bone of said human patient, wherein said surgical instrument is further adapted to operate through the hole in the pelvic bone on the opposite side of the acetabulum of said human patient, wherein the surgical instrument is further adapted to introduce a prosthesis through the hole in the pelvic bone and into the hip joint, to fixate an artificial hip joint surface, or a part of an artificial hip joint surface, to the pelvic bone or the femoral bone, and to place or fixate fixation elements to the pelvic bone or a prosthetic part in the hip joint.

3. The method according to claim 1 , wherein the step of fixating an artificial hip joint surface, or a part of an artificial hip joint surface, to the pelvic bone or the femoral bone is performed using a surgical instrument adapted to assist in operating in the hip joint from the abdominal side of the pelvic bone of said human patient, wherein said surgical instrument is further adapted to operate through the hole in the pelvic bone on the opposite side of the acetabulum of said human patient, wherein the surgical instrument is further adapted to introduce a prosthesis through the hole in the pelvic bone and into the hip joint, to fixate an artificial hip joint surface, or a part of an artificial hip joint surface, to the pelvic bone or the femoral bone, and to place or fixate fixation elements to the pelvic bone or a prosthetic part in the hip joint.

4. The method according to claim 1 , wherein the step of connecting at least two prosthetic parts to each other after insertion into the hip joint is performed using a surgical instrument adapted to assist in operating in the hip joint from the abdominal side of the pelvic bone of said human patient, wherein said surgical instrument is further adapted to operate through the hole in the pelvic bone on the opposite side of the acetabulum of said human patient, wherein the surgical instrument is further adapted to introduce a prosthesis through the hole in the pelvic bone and into the hip joint, to fixate an artificial hip joint surface, or a part of an artificial hip joint surface, to the pelvic bone or the femoral bone, and to place or fixate fixation elements to the pelvic bone or a prosthetic part in the hip joint.

5. The method according to claim 1 , wherein the step of introducing a prosthesis into the hip joint is performed using a surgical instrument adapted to assist in operating in the hip joint from the abdominal side of the pelvic bone of said human patient, wherein said surgical instrument is further adapted to operate through the hole in the pelvic bone on the opposite side of the acetabulum of said human patient, wherein the surgical instrument is further adapted to introduce the prosthesis through the hole in the pelvic bone and into the hip joint, to fixate an artificial hip joint surface, or a part of an artificial hip joint surface, to the pelvic bone or the femoral bone, and to place or fixate fixation elements to the pelvic bone or a prosthetic part in the hip joint.

6. A method of treating a hip joint of a human patient, 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 the body,
placing at least two laparoscopic or arthroscopic trocars in said cavity,
inserting a camera through one of the laparoscopic or arthroscopic trocars into said cavity,
inserting at least one dissecting tool through one of said at least two laparoscopic or arthroscopic trocars,
dissecting an area of the pelvic bone on an abdominal side of the pelvic bone,
creating a hole in said dissected area, said hole passing through the pelvic bone and into the hip joint of the human patient, and
further comprising at least one of the steps selected from the group consisting of
placing or fixating fixation elements to the pelvic bone or to a prosthetic part in the hip joint,
fixating an artificial hip joint surface, or a part of an artificial hip joint surface, to the pelvic bone or the femoral bone,
connecting at least two prosthetic parts to each other after insertion into the hip joint, and
introducing a prosthesis into the hip joint,

wherein said at least one step is conducted through said hole in the pelvic bone.

7. The method according to claim 6 , wherein the step of placing or fixating fixation elements to the pelvic bone or to a prosthetic part in the hip joint is performed using a surgical instrument adapted to assist in operating in the hip joint from the abdominal side of the pelvic bone of said human patient, wherein said surgical instrument is further adapted to operate through the hole in the pelvic bone on the opposite side of the acetabulum of said human patient, wherein the surgical instrument is further adapted to introduce a prosthesis through the hole in the pelvic bone and into the hip joint, to fixate an artificial hip joint surface, or a part of an artificial hip joint surface, to the pelvic bone or the femoral bone, and to place or fixate fixation elements to the pelvic bone or a prosthetic part in the hip joint.

8. The method according to claim 6 , wherein the step of fixating an artificial hip joint surface, or a part of an artificial hip joint surface, to the pelvic bone or the femoral bone is performed using a surgical instrument adapted to assist in operating in the hip joint from the abdominal side of the pelvic bone of said human patient, wherein said surgical instrument is further adapted to operate through the hole in the pelvic bone on the opposite side of the acetabulum of said human patient, wherein the surgical instrument is further adapted to introduce a prosthesis through the hole in the pelvic bone and into the hip joint, to fixate an artificial hip joint surface, or a part of an artificial hip joint surface, to the pelvic bone or the femoral bone and to place or fixate fixation elements to the pelvic bone or a prosthetic part in the hip joint.

9. The method according to claim 6 , wherein the step of connecting at least two prosthetic parts to each other after insertion into the hip joint is performed using a surgical instrument adapted to assist in operating in the hip joint from the abdominal side of the pelvic bone of said human patient, wherein said surgical instrument is further ad
