An apparatus for holding a first portion of a bone and a second portion of a bone together for the bone to heal. A method for holding a first portion of a bone and a second portion of a bone together for the bone to heal. A suture. A grommet for a bone. A method for securing a suture through a bone.

Hard or soft tissue closure

A graft protection device suitable for protecting a bone-tendon-bone graft used during anterior cruciate ligament reconstruction. The graft protection device comprises a distal blocking member, a proximal releasable holding sleeve and an elongated connecting portion connecting the blocking member with the holding sleeve. A radially extending handle is attached to the holding sleeve in order to enable a user to longitudinally and rotationally position the graft protection device along the shaft of an elongated driver when the device is inserted through an opening into a joint. A method of utilizing the graft protection device is also disclosed comprising the steps of guiding a screw/driver/protector assembly along a guide wire into proper position within a bone tunnel, driving the screw into place by turning it and thereby sliding it along the blocking member past a portion of the ligament graft and then locking the guide wire to the driver and removing it along with the driver/protector assembly in a single motion. A lockable, cannulated screw driver is disclosed to facilitate using the graft protection device with the method disclosed herein.

Ligament graft protection apparatus and method

A bone fixation screw employs plural interleaved and axially symmetrical spiral threads. The threads are machined at the screw tip to form symmetrically disposed leading cutting edges. An interference-screw embodiment has a central axial cannula and a female hexagonal drive socket. The plural threads assist in unbiased starting and fast advance of the screw.

Interference bone-fixation screw with multiple interleaved threads

A surgical screw driver for inserting bone screws in bone tunnels in ligament reconstruction has, in a preferred embodiment, a rotatable operating shaft disposed at an angle to a drive shaft. A mechanism is on the drive shaft for retaining a bone screw. Methods of arthroscopic cruciate ligament reconstruction include the steps of introducing a surgical screw driver through a portal that is offset from the longitudinal axis of a bone tunnel and driving a bone screw mounted on the driver in the bone tunnel to fixate a bone block in the bone tunnel.
