Definitions
- the present invention relates to a ligament reconstruction tool and a ligament reconstruction method. More specifically, the present invention relates to a ligament reconstruction tool and a ligament used for forming a ligament fixation tunnel in a joint bone when reconstructing a ligament such as a damaged anterior cruciate ligament (ligament connecting the femur and tibia). Reconstruction method.
- a bone hole (tunnel) is formed in the tibia through the bone wall, and one femur has a circular cross-section through the bone wall.
- a columnar bone hole is formed.
- a loop-shaped graft ligament is inserted in communication with these bone holes, and one end of the ligament is fixed to the femur via metal fittings.
- a cylindrical screw fitting main body is inserted into the bone hole on the tibia side from the open end side (see JP-A-2001-25478).
- the present inventor has conducted intensive studies, and as a result, the cross section of the ligament is not circular but is substantially rectangular or substantially oval (for example, short axis X long axis: 4 mm X Focus on the fact that there is a large gap between the inner surface of the conventionally formed circular bone (for example, inner diameter: 8-10 mm ⁇ ), and if this gap is made smaller, The present inventors have found that the ligaments can be integrated more quickly, and have completed the present invention.
- the present invention includes a front end portion and a body portion having two parallel through holes arranged side by side, and a rear end portion having two coaxial two through holes arranged side by side,
- the tip and the torso strike their cross-sections from the rear end and drive the tip and the torso into the joint bone to form a flat tunnel.
- a ligament reconstruction tool characterized by having a long and uniform substantially oval or substantially rectangular shape.
- the cross section of the bone hole formed by making the cross section of the distal end portion and the torso section into an oval or rectangular shape instead of a simple circular shape can be used to make the cross section of the normal ligament.
- the inner surface of the bone hole and the outer surface of the ligament are brought close to each other over the entire surface, so that the two can be united earlier and integrally, and the bonding force is increased.
- the present invention relates to a ligament reconstruction method using the above-described ligament reconstruction tool, wherein one guide pin is inserted into a joint bone and the inserted portion of the guide pin is inserted. After over-drilling to a predetermined depth, insert the two guide pins on both sides of the guide pin in the next step, then remove the center guide pin, and insert the two guide pins. Then, the rear end of the ligament reconstruction tool is hit, and the distal end and the torso are driven toward the outer cortex of the joint bone, so that a flat portion through which one end of the ligament can be inserted.
- a ligament reconstruction method characterized by forming a tunnel.
- the ligament reconstruction tool mainly has a distal end portion and a torso portion, which are composed of a distal end portion and a torso portion, and a rear end portion, have two parallel through holes arranged side by side, and have a cross section of A substantially oval or substantially rectangular shape that is long in the direction in which the two through holes are arranged.
- the ratio of the long axis to the short axis of the substantially oblong or substantially rectangular is 2 to 5.
- the substantially elliptical shape include a substantially elliptical shape and a track-shaped elliptical shape.
- the track-shaped oval is preferably composed of a pair of parallel linear portions having a length of 4 to 8 mm and an interval of 36 mm, and a pair of semicircular portions connecting both ends of the linear portion. .
- the length of the short side is preferably 3-6 mm and the length of the long side is preferably 7-14 mm. Therefore, its cross-sectional area is preferably 21-84 mm 2 It is preferable that the tip and the trunk have a length of 100 to 200 mm.
- the rear end portion has two through-holes coaxial with the two through-holes of the tip end portion and the body portion, and usually has a thick oval or disc shape having a larger cross section than the tip end portion.
- the tip can be driven into the joint bone by tapping with a hammer, thereby forming a flat tunnel in the joint bone with a cross section corresponding to the shape of the cross section of the tip and torso. So that you can
- the depth of the round hole is 10 to 30 mm and the length of the flat tunnel is 10 to 30 mm.
- ligament reconstruction is anterior cruciate ligament reconstruction
- the joint bone is the tibia.
- an artificial ligament can be used, but a transplanted ligament, particularly a patella tendon with bone of a human (patient or cadaver) is desirable.
- FIG. 1 is a front view showing one embodiment of a ligament reconstruction tool according to the present invention
- FIG. 2 is a cross-sectional view along AA
- FIG. 3 is a side view of FIG.
- FIG. 4-11 is an explanatory view illustrating a ligament reconstruction method using the ligament reconstruction tool of the present invention
- Figs. 12-14 illustrate another ligament reconstruction method using the ligament reconstruction tool of the present invention.
- a front cruciate ligament reconstruction dilator (dilator, extension tool) 1 as a ligament reconstruction tool according to the present invention has a distal end portion having two parallel through holes 2 and 3 arranged side by side. 4 and a trunk portion 5, and a rear end portion 8 having two through holes 6, 7 coaxial with the two through holes 2, 3.
- the tip section 4 and the body section 5 have a cross section that is substantially oval in the direction in which the through holes 2 and 3 are arranged, more specifically, a substantially track-like (track-like track for athletic competition). It is circular.
- the rear end 8 has a substantially track-shaped elliptical cross section larger than the front end 4 and the trunk 5.
- each through hole 2, 3, 6, 7 2.5mm ⁇
- the length of the straight part in the cross section of the tip 4 and the trunk 5 6mm
- rear The length of the straight portion in the cross section of the end 8 is 17 mm, and the interval is 15 mm.
- the distal end 4 has cuts 9 and 10 on the front and back, respectively, and hits the rear end 8 of the ligament reconstruction dilator 1 to cut the distal end 4 and torso 5 into the surface bone of the joint bone. It should be able to be driven smoothly from the cortex to the ligament attachment site in the joint.
- this guide pin 11 is over-drilled from the front of the tibia K to a depth of 20 mm to form a round hole 12 (see Fig. 5).
- Each through hole 2, 3, 6, 7 of the anterior cruciate ligament reconstruction dilator 1 is connected to two guide pins 13, 14. Applying force S, hammer hit the rear end 8 of the anterior cruciate ligament reconstruction dilator 1 and hammer the tip 4 and torso 5 toward the medial cortex of the tibia K, and a flat tunnel of approximately 5mm x 10mm Form 15 (see Figures 10 and 11).
- one end of a patella tendon with a bone is appropriately inserted through a round hole 12 by a conventional method, and is inserted into a button or a nude. Fixed. The other end of the patellar tendon with bone is guided through the round hole 12 and the flat tunnel 15 to the femur D, and to the flat tunnel 18 formed in the later ligament reconstruction method, as appropriate, using a button or nude. Fixed.
- the cross-sectional shape of the distal end portion of the anterior cruciate ligament reconstruction tool is not circular, but is substantially oblong or substantially rectangular, and thereby the bone hole formed
- the cross-section is close to the cross-section of the normal ligament, thereby bringing the inner surface of the bone hole and the outer surface of the ligament closer together, so that the two can be united earlier and integrally, and To increase.
