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 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 bone fixation assembly may include a male member removably couplable with a female member. The male member may include a male load-sharing feature having at least one male load-sharing surface. The female member may include a female load-sharing feature having at least one female load-sharing surface. The female load-sharing feature may be positioned and shaped to receive the male load-sharing feature therein. In response to a bending load acting on the bone fixation assembly, at least one of the male member and the female member may bend such that, at least a portion of the at least one male load-sharing surface engages with at least a portion of the at least one female load-sharing surface to distribute the bending load between the male member and the female 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 implant system may include a plurality of bone anchors, a superior rod attachable to a superior portion of a bone via the bone anchors, and an inferior rod attachable to an inferior portion of the bone via the bone anchors. The superior rod may have a superior end, and the inferior rod may have an inferior end. The superior rod may telescopically engage the inferior rod such that a cavity is present within at least one of the superior rod and the inferior rod and such that a length of the combined superior and inferior rods, measured between the superior end and the inferior end, is adjustable. The cavity may contain a micropump and a chamber. The micropump may be configured to expel fluid into the chamber to urge the length to increase.

Abstract: A dynamic compression implant may be insertable into a bone, and may have a distal member with distal bone-engaging threads, a proximal member that slidably engages 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 distally away from the proximal member, the tension member elongates and urges the distal member to move proximally toward the proximal member. The bone screw may further have an interpositional member, formed separately from the proximal member and the distal member, that cooperates with the proximal member and the distal member to form a torque transmission feature that transmits torque between the proximal member and the distal member. The dynamic compression implant may be a bone screw, intramedullary implant, or other implant that applies compression across two bone portions.
