Abstract: A graft suspension device for suspending a ligament in a bone hole having a first loop and a second loop suspending from an 8-hole anchor, and a cradle at the opposite end of the loops to the anchor. The loose ends of the suture are routed through holes in the anchor separate from the loops and are joined together to form a single tail. A finger loop allows a surgeon to adjust the distance of the cradle from the anchor with the cradle staying centered with respect to the anchor as the distance is adjusted.

Abstract: A device for containing bone graft material includes a mesh outer sleeve extending longitudinally from a proximal end to a distal end and sized and shaped to correspond to a profile of an outer surface of a target bone. The outer sleeve includes a longitudinal slot extending along a length thereof. The device also includes a mesh inner sleeve connected to an interior surface of the outer sleeve via at least one strut so that a bone graft collecting space is defined therebetween. The inner sleeve is sized and shaped to correspond to a profile of a medullary canal of the target bone. In addition, the device includes an interstitial mesh extending radially away from an exterior surface of the inner sleeve toward an interior surface of the outer sleeve to hold graft material in the bone graft collecting space.

Abstract: A femoral slideway and femoral slideway/femur-size template combination is employed to create an installed knee prosthesis that creates a reduced amount of stress in the collateral ligaments relative to previous prosthesis. In one embodiment, the reduced stress is achieved by employing a femoral slideway/femur-size template combination which results in installation of a femoral slideway which has a smaller dorsal-ventral dimension than a corresponding dimension of the femur prior to resection.

Abstract: A soft tissue graft suitable for replacing a tendon or ligament is fastened in a bone opening provided in a human or animal patient by press-fitting an end portion of the graft and a fastener into the bone opening such that the graft end portion is pressed against a first portion of the bone wall inside the bone opening. The fastener is anchored in a second portion of the bone wall by liquefying a material having thermoplastic properties by the fastener and making the fastener penetrate into the bone wall. An end portion of the graft is tied to the fastener with the aid of at least one suture extending from the graft end portion. Tying is carried out after anchoring, during anchoring or between anchoring and press-fitting. The tied connection between the fastener and the graft end portion successfully counteracts potential graft slipping.

The device also includes an inner member formed via an inner mesh sheet coiled about a longitudinal axis thereof. The inner member is movable between a first biased coiled configuration and a second coiled configuration. A diameter of the inner member in the first coiled configuration is larger than a diameter of the inner member in the second coiled configuration.

Abstract: During hip replacement surgery, a practitioner can attach a distal stem to a femur of the patient and can then fixedly attach a proximal body to the distal stem using a bolt. Prior to tightening, the bolt can be heated to an elevated temperature greater than average human core body temperature. The practitioner can tighten the bolt to a specified torque while the bolt is at the elevated temperature. After tightening, the bolt cools to average human core body temperature and experiences a tensile stress due to the effects of thermal expansion. The tensile stress in the bolt produces a compressive force between the distal stem and the proximal body. The compressive force can increase the attachment strength of the bolt to the distal stem and the proximal body, beyond what can be achieved by solely torquing the bolt to the specified level during surgery without first heating the bolt.
