METHODS AND DEVICES FOR POSITIONING AND SECURING LIGAMENT GRAFTS

摘要

Methods and devices for positioning and securing ligament grafts are provided. In general, the devices and methods utilize an implant having a particular outer surface profile and a bone tunnel having a complementary profile to provide a form fit between the implant and bone that utilizes friction to position and secure a ligament graft within the bone. Such an implant can be used in conjunction with a variety of ligament grafts, including hamstring ligament grafts. In addition, an “outside in” approach can be utilized with the implant to minimize the risk of damaging adjacent tissue during an operation and provide enhanced surgeon control. The devices and methods can be utilized in connection with repairing or replacing ligaments in a variety of joints, but can in some embodiments have particular utility in cruciate ligament reconstruction procedures.

主权项

1. An implant for securing a ligament graft, comprising:
a body having a conical outer profile extending along a longitudinal axis thereof between a proximal end of the body and a tapered distal end of the body, wherein the body includes:
a first set of opposed slots formed in an outer surface thereof that extend along the longitudinal axis and a transverse slot formed in the proximal end that extends between the first set of opposed slots; anda bore formed through the body that is transverse to the longitudinal axis and angularly offset from the first set of opposed slots.
