Hip joint method
A method of treating a hip joint of a human patient using a pelvic drill comprising a driving member, a bone contacting and an operating device for operating said driving member. The method comprise the steps of creating a hole passing through the pelvic bone and into the hip joint of the human patient, and providing at least one hip joint surface to the hip joint, through said hole in the pelvic bone of the human patient. In one embodiment the method includes inserting a needle or tube like instrument into the patient's body for filling a part of the patient's body with gas and thereby expanding a cavity within the body.
1. A method of treating a hip joint of a human patient, said method comprising the steps of:
creating a hole passing through a pelvic bone and into the hip joint of the human patient, and
providing at least one hip joint surface to the hip joint, from the abdominal side of the pelvic bone, through said hole in the pelvic bone of the human patient.
2. The method according to claim 1 , said method further comprising the steps of:
inserting a needle or 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/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, and
dissecting an area of the pelvic bone on the opposite side from the acetabulum the hip joint,
wherein the step of creating a hole passing through the pelvic bone comprises creating the hole in said dissected area using a pelvic drill.
3. The method according to claim 2 , further comprising the step of reaming the acetabulum or the caput femur of the hip joint.
4. The method according to claim 2 , wherein said cavity is located in at least one of:
a. the abdominal region,
b. the inguinal region, and
c. the pelvic region.
5. The method according to claim 1 , further comprising the step of fixating the hip joint surface to the caput femur or to the pelvic bone by means of form fitting mechanical fixating members, bone cement or adhesive.
6. The method according to claim 1 , further comprising the step of closing said hole in the pelvic bone by means of any one of: bone cement, a bone plug, and a prosthetic part.
7. The method according to claim 1 , further comprising the step of placing a mould inside of the hip joint of the human patient and subsequently injecting a fluid into said mould placed inside of the hip joint of the human patient.
8. The method according to claim 7 , further comprising the steps of:
a. placing at least one sealing member between the acetabulum and the caput of the hip joint femur, thus creating a sealed area between the acetabulum and the caput femur of the hip joint, and
b. injecting a fluid into said sealed area.
9. The method according to claim 1 , further comprising a step of cutting the skin of the human patient in at least one of:
a. the abdominal wall,
b. the inguinal area, and
c. the pelvic region.
10. The method according to claim 2 , wherein the step of dissecting an area of the pelvic bone comprises dissecting at least one of:
a. an area between peritoneum and the pelvic bone,
b. an area between the pelvic bone and the surrounding tissue,
c. an area of the pelvic bone comprises dissecting an area of the pelvic region,
d. an area of the inguinal region, and k, an area of the abdominal cavity.
11. The method according to claim 1 , wherein the hole is created with a pelvic drill comprising a driving member and a bone contacting member which together form an elongated member, and wherein the method further comprises the step of placing said elongated member to act as a first supporting point for the bone contacting member in a femoral bone of the hip joint and a second supporting point in the pelvic bone.
12. The method according to claim 11 , further comprising the step of connecting an operation device giving force to said driving member.
13. The method according to claim 12 , wherein said elongated member receives said force from an operation device in the abdomen or outside the patient's body, lateral of a proximal portion of the femoral bone of the hip joint.
