Integrated adjustable button-suture-graft construct with two fixation devices
An adjustable button/loop device for securing biologic material in bone, such as for ACL reconstruction. The device has a pair of button/loop constructs, each including a flexible, adjustable loop integrated with a fixation device (for example, a wedge). Biologic material (for example, soft tissue, graft, ligament or tendon) is secured to the two fixation devices, and the construct is inserted into a pair of bone sockets/tunnels, such as into a tunnel in the tibia and a socket in the femur. The biologic material is secured within the bone by passing the buttons though respective bone sockets/tunnels, flipping and seating the buttons outside the bone, and then adjusting the lengths of the flexible adjustable loops passing through the buttons and the respective fixation devices, with the graft extending between the fixation devices thereby appropriately secured in the bone.
1. A method of tissue reconstruction, comprising:
providing a first construct attached to a first fixation device, and a second construct attached to a second fixation device, wherein at least one of the first and second constructs is adjustable and is formed of two splices and two adjustable loops that are interconnected;
securing a biological material to the first and second fixation devices to form a biologic construct;
inserting the biologic construct comprising biologic material secured to each of the first and second fixation devices within a first bone tunnel and a second bone tunnel;
securing the first fixation device within the first tunnel and the second fixation device within the second tunnel; and
pulling on the at least one of the first and second constructs that is adjustable to adjust the length of at least one of the first and second constructs without tying knots, to fixate the biologic construct within the first and second bone tunnels.
2. The method of claim 1 , wherein both of the first and second constructs have an adjustable length, to allow positioning of the biologic construct within the first and second bone tunnels.
3. The method of claim 1 , further comprising the steps of:
attaching the first construct to a first member with a first configuration and provided with a plurality of first apertures;
attaching the second construct to a second member with a second configuration and provided with a plurality of second apertures;
advancing the first member through the first bone tunnel so as to exit the first bone and to pivot and engage a cortical surface of the first bone; and
advancing the second member through the second bone tunnel so as to exit the second bone and to pivot and engage a cortical surface of the second bone.
4. The method of claim 3 , wherein the first member is a button provided with apertures, and the second member is a button provided with apertures, and wherein the first construct is passed through the apertures of the first member and the second construct is passed through the apertures of the second member.
