    Abstract: A system for harvesting bone material from a bone may include a rotary cutter defining a rotary cutter longitudinal axis extending between a rotary cutter proximal end and a rotary cutter distal end. The rotary cutter may have a drive shaft configured to receive input torque, and an osteochondral cutter configured to cut the tissue and receive the tissue material in response to rotation of the osteochondral cutter under pressure against the tissue. The system may further include a bone port defining a bone port longitudinal axis extending between a bone port proximal end and a bone port distal end. The bone port may have a bone port cannulation sized to closely fit over the osteochondral cutter. At least one of the bone port proximal end and the bone port distal end may be securable to the tissue. A stratiform tissue graft may be delivered through the bone port.

    Abstract: A first bone portion may be secured to a second bone portion by forming a hole in the first bone portion and the second bone portion and inserting a bone screw into the hole. The bone screw may have a proximal member, a distal member, and a tension member with a proximal end coupled to the proximal member and a distal end coupled to the distal member. Torque may be applied to the bone screw to move the distal member away from the proximal member such that the tension member elongates and urges the distal member to move toward the proximal member. The torque may be transmitted from the proximal member to the distal member via a torque transmission feature. A bending transmission feature, displaced proximally or distally from the torque transmission feature, may be positioned to share bending loads between the proximal member and the distal member.

    Abstract: A tether assembly may be attached to a bone to correct a rotational deformity. The bone may have a growth plate that separates a first section of the bone from a second section of the bone. The tether assembly may have a tether member with a first end, a second end, and a central portion extending between the first end and the second end. The first end may have a closed outer wall that defines and fully bounds a first aperture. The second end may have an open outer wall that defines and partially bounds a second aperture. The open outer wall may define a slot in communication with the second aperture. The first and second ends may be securable to the first and second sections of the bone via coupling members inserted through the first and second apertures and anchored in the first and second sections, respectively.

    Abstract: A bone screw may be insertable into a bone, and may have a proximal member, a distal member with bone-engaging threads, wherein the distal member is configured to slidably engage the proximal member such that a variable-length cavity is defined within the proximal member and the distal member, and a tension member residing at least partially within the variable-length cavity. The tension member may have a proximal end coupled to the proximal member and a distal end coupled to the distal member such that, in response to motion of the distal member away from the proximal member, the tension member elongates and urges the distal member to move toward the proximal member. The proximal member and the distal member may be interconnected to share bending loads at a bending transmission feature.

    Abstract: A trephine may be used to form a tunnel through bone and/or cartilage. The trephine may have a trephine body with a generally tubular shape centered on a trephine body longitudinal axis, and a trephine body distal rim. The trephine may also have a drive shaft that receives torque and transmits the torque to the trephine body. The trephine body distal rim may lie substantially in a plane that is non-perpendicular to the trephine body longitudinal axis. The trephine may further have a cutting tooth extending distally from the trephine body distal rim. The cutting tooth may have a first distal tip and a second distal tip displaced circumferentially from the first distal tip. The trephine may be advanced while rotating to form the tunnel through bone and a first, adjacent cartilage surface of a joint, without breaching a second cartilage surface on the opposite side of the joint.

    Abstract: A bone screw may be insertable into a bone. The bone screw may have a distal member with bone-engaging threads, a proximal member configured to slidably engage the distal member, and a tension member with a proximal end coupled to the proximal member, and a distal end coupled to the distal member such that, in response to motion of the distal member away from the proximal member, the tension member elongates and urges the distal member to move toward the proximal member. The tension member may be configured such that, at a minimum length of the bone screw, the tension member is pre-stretched so that the tension member is under tension to urge the bone screw to shorten. The bone screw may be inserted in the pre-stretched state. A pre-stretch driver may be used to tension the bone screw prior to or during insertion.
