Abstract
A bone graft retention plate for implantation into a human glenoid and provides stabilization and compression of bony graft material is disclosed. The plate includes channels or apertures for suture or polymer retention cerclage that exhibit curved, smooth surfaces within the plate to allow the retention cerclage to pass through the plate while limiting friction and thus protecting the integrity of the retention means. The plate also includes surface features, such as spikes and posts, to provide further stabilization and implantation positioning. The plate features result in the distribution of forces across the surface area of a bone graft and achieve satisfactory compression of the bone graft against the glenoid without using fixation screws. An associated implantation technique uses a cerclage of suture or tape to bind the implant within the glenoid and may be employed in both open and arthroscopic surgical procedures.
