Disclosed is directed to a method for restoring bone in an animal comprising: accessing a site to be restored; loading a syringe body with a flowable bone graft material; mating the syringe body with a delivery tube; positioning the delivery tube at the site to be restored; using a syringe piston to advance the said material into the delivery tube; using the syringe piston or a plunger that mates with the delivery tube after removal of the syringe body to deliver the bone graft to the site at a force of less than 50 lbs. extrusion force; wherein said material is at least 75% porous with a mineral to polymer ratio of 80:20.

A bone screw, for drawing first and second bone fragments together, includes a shaft having a distal section and a proximal section. The distal section has a first external male screw thread and a minor diameter. The proximal section has a second external male screw thread. A major diameter of the distal section is larger than a major diameter of the proximal section. The bone screw includes a sleeve that has an internal female screw thread configured to mate with the second male screw thread. A distal portion of the sleeve has an outer diameter. The outer diameter is equal to or smaller than the minor diameter of the distal section of the shaft.

The present disclosure relates, in some aspects, to orthopaedic implants for securing soft tissue to bone and methods for using the same. One particular implant comprises a first exposed porous surface region, having pores for promoting bone ingrowth, and a second exposed porous surface, having pores for promoting soft tissue ingrowth. At least some of the pores of the first exposed porous surface region may be seeded with osteocytic factors and at least some of the pores of the second exposed porous surface region may be seeded with fibrocytic factors. Such orthopaedic implants can advantageously facilitate regeneration of the soft tissue to bone interface.

An anchor for anchoring tensile members to bone includes: a housing extending along a central axis, with a hollow interior; a collet in the hollow interior having a central bore for accepting tensile members and an exterior surface, the collet being configured to swage around and against tensile members; a sleeve having a peripheral wall defining interior and exterior surfaces, the sleeve disposed in the housing's hollow interior axially adjacent to the collet, and movable parallel to the central axis between first and second positions; and wherein at least one of the collet exterior surface and the sleeve interior surface is tapered and the sleeve and the collet are arranged so movement of the sleeve from the first position to the second position causes the sleeve interior surface to bear against the collet exterior surface, causing the collet to swage radially inwards around and against one or more tensile members.

Assemblies and methods for fixation of bone or bone fragments using an orthopedic plate, a modular peg, and a compression screw. The modular peg is screwed into one of the apertures of the orthopedic plate. The modular peg may include an aperture having screw threads designed to receive the threads of the compression screw and serve as an anchor for the compression screw. By rotating the compression screw in relation to the modular peg, the compression screw may advance through the aperture of the modular peg, drawing the head of the screw toward the modular peg, and compressing the bone or bone fragments.

Disclosed in an orthopedic implant that comprises a spacer portion having a superior portion and an inferior portion, and a staple portion. The staple portion is integral with the spacer portion and comprises a crown portion and first and second leg portions, the first and second leg portions having distal end that converge front the crown portion and that are composed of a material that has superelastic properties at body temperatures, whereby the first and second leg portions are configured to impart a compressive biasing force when the implant is installed with the legs under tension.

The disclosure describes systems and methods for altering bone sections in a patient. In one embodiment, a system may include an intramedullary implant including: a housing configured to be secured to a first section of bone, where the housing may include one or more shaft engaging grooves axially extending along an inner surface thereof; a distraction shaft configured to be secured to a second section of bone, where the distraction shaft may include one or more grooves axially extending along an inner surface thereof. The system may further include an actuator disposed within the housing and operably coupled to the distraction shaft, and in response to rotation of the actuator, the one or more grooves of the distraction shaft may engage with the one or more shaft engaging grooves of the housing, causing axial displacement of the distraction shaft relative to the housing.
