Abstract

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.

First claim

1 .- 89 . (canceled)

90 . A method of treating a hip joint of a human patient said method comprising 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, from the abdominal side of the pelvic bone through said hole in the pelvic bone of the human patient.

91 . The method according to claim 90 , 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, dissecting an area of the pelvic bone on the opposite side from the acetabulum, wherein the step of creating a hole passing through the pelvic bone comprised creating the hole in said dissected area using a pelvic drill, said hole passing through the pelvic bone and into the hip joint of the human patient.

92 . The method according to claim 91 , further comprising the step of reaming the acetabulum or caput femur.

93 . The method according to claim 90 , 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.

94 . The method according to claim 90 , 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.

95 . The method according to claim 90 , 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.

96 . The method according to claim 95 , further comprising the steps of:
a. 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 b. injecting a fluid into said sealed area.

97 . The method according to claim 90 , further comprising a step of cutting the skin of the human patient in at least one of the areas selected from a list consisting of:
a. the abdominal wall, b. the inguinal area, and c. the pelvic region.

98 . The method according to claim 91 , wherein said cavity is located in at least one of the areas selected from a list consisting of:
d. the abdominal region, e. the inguinal region, and f. the pelvic region,

99 . The method according to claim 91 , wherein the step of dissecting an area of the pelvic bone comprises dissecting an area at least one of the areas selected from a list consisting of:
g. an area between peritoneum and the pelvic bone, h. an area between the pelvic bone and the surrounding tissue i. an area of the pelvic bone comprises dissecting an area of the pelvic region, j. an area of the inguinal region, and k. an area of the abdominal cavity,

100 . The method according to claim 90 , wherein hole is created with a pelvic drill comprising a driving member and bone contacting organ which together from an elongated member, and the method comprises the step of placing said elongated member so as to achieve a first supporting point for the bone contacting organ in the femoral bone and a second supporting point in a pelvic bone.

101 . The method according to claim 100 , connecting an operation device giving force to said driving member from outside the body, lateral on the opposite side of said hip joint outside the opposite side ilium pelvic bone outside the body.

102 . The method according to claim 100 , wherein said elongated member is receiving said force from an operation device in the abdomen or outside the body, lateral of the proximal femoral bone.
