Filed:

Jan 22, 2008

Appl. No.:

12/010184

Inventors:

James L. Cook - Columbia MO, US
David O. Shepard - Naples FL, US
Anthony Orozco - Woodstock GA, US

Assignee:

Arthrex, Inc. - Naples FL

International Classification:

A61B 17/04
A61B 17/84
A61F 2/08

US Classification:

606232, 606300, 623 1312, 128898

Abstract:

A method for stabilization of a cranial cruciate ligament in canines using a suture-button construct. The method includes the steps of drilling a hole across the femur and the tibia, passing a needle with a pull-through suture strand through the femoral hole, and applying a tensile force to the pull-through suture strand and a suture tape such that a first button lies sideways for passage through the femoral hole, advancing the first button through the femoral hole until the first button exits the femoral hole, passing the needle with the pull-through suture strand through the tibial hole, applying a tensile force to the pull-through suture strand and the suture tape such that the first button lies sideways for passage through the tibial hole, flipping the first button to engage it against the tibia, pulling free ends of the suture tape to advance a second button and to seat and secure it against the femur.

Abstract:

An apparatus and method for stabilization of a cranial cruciate ligament deficient stifle in canines using a suture-button construct. The method includes the steps of drilling a femoral hole across a distal femur, passing a needle with a pull-through suture strand of a suture-button construct through the femoral hole, and applying a tensile force to the pull-through suture strand and a suture tape or strand of the construct such that a first button of the suture-button construct lies sideways for passage through the femoral hole, advancing the first button through the femoral hole by pulling the pull-through suture strand until the first button exits the femoral hole, drilling a tibial hole and passing the needle with the pull-through suture strand through the tibial hole, applying a tensile force to the pull-through suture strand and the suture tape or strand of the construct such that the first button lies sideways for passage through the tibial hole, flipping the first button to engage the first button against the medial tibial cortex and subsequently cutting and removing the pull-through suture strand, pulling free ends of the suture tape or strand to advance a second button of the suture-button construct and to seat the second button against the femur, and securing the second button against the femur.

Abstract:

A suture needle construct and method for extracapsular ligament reconstruction in mammals. The joint is first is first explored, and the damaged ligament and meniscus are debrided. The joint capsule is closed and a tunnel is created at the appropriate location in the proximal tibia for tibial fixation. Subsequent to the formation of the tibial tunnel, a suture having a substantially curved needle at one end and a substantially straight needle at the other end is brought in the proximity of the joint. The suture is passed around the lateral fabella using the substantially curved needle, then deep to the patellar ligament using the substantially straight needle, and through the tibial tunnel using the straight needle. The needles are cut off, and the sutures are tensioned over repair site.
