The invention relates to an interlocking nail (10) for fixation of transverse and short spiral fractures of, long bone, particularly shaft of the femur, tibia and humerus, having Graft extrusion space/slot (101) for holding stem cells graft and 4 or 5 holes for putting interlocking bolts from lateral to medial direction. Constant compression achieved (irrespective of weight bearing cycle) at the fracture site by tightening of the Endo-Compression Screws (108, 109 and 110) results in stimulation of stem cells and reduction in bone gap, thus enhances bone healing and union manifolds.

Systems, devices, and methods for performing Lapidus bunionectomy procedures are disclosed. An example method includes inserting a plurality of metatarsal pins into the first metatarsal at a first predetermined spacing relative to the first tarsometatarsal (TMT) joint, excising the first TMT joint by cutting the bases of the first metatarsal and the first cuneiform proximate the first TMT joint, inserting a plurality of cuneiform pins into the first cuneiform at a second predetermined spacing relative to the first TMT joint, compressing the first TMT joint using a compressor block such that a cut face of the first metatarsal contacts a cut face of the first cuneiform, and fixing the first TMT joint using a bone plate and a plurality of bone screws. At least one of the plurality of bone screws may be a cross screw extending at an angle of less than 90 degrees relative to the bone plate and may anchor the resected first TMT joint to the second metatarsal or the second cuneiform to prevent recurrence of the bunion.

A disposable intramedullary device for temporary use for treatment of limb infections comprising a solid core of variable cross-section, including a distal portion, a middle portion and a proximal portion, said proximal portion and distal portion including anchoring regions consisting of through-holes being passed through by bone anchoring means. Outside said anchoring regions, said solid core is coated with a polymer layer which also includes antibiotic, the outer diameter of the solid core and polymer layer assembly being equivalent to that of an intramedullary channel, and the outer diameter of said solid core in said anchoring regions being equivalent to that of said intramedullary channel.

A means of fastening an intramedullary nail to the surface of a bone.

A intramedullary fixation device for use in fixating, after an osteotomy or fracture, segments of a long, tubular bone that has been prepared for the use with the device by cutting into the bone a longitudinal-axis-aligned slot that extends from the free surface to the medullary cavity of the bone, includes: (a) an intramedullary beam whose beam cross-sectional shape varies along the beam's longitudinal axis, (b) a fin whose fin cross-sectional shape varies along the fin's longitudinal axis and a portion of which is attached to the beam surface, (c) wherein the area of any beam cross-sectional section is set so that it can be located in the bone's medullary cavity, and (e) wherein the area of any fin cross section is set so that it can be accommodated in the slot that is cut into the bone.

A stent is disclosed that has an elongated body composed of a bioabsorbable polymer having a proximal end, a distal end, two open spiral channels formed on the exterior surface of the body to provide fluid communication between the proximal end and the distal end. The stent has a central lumen open at the proximal and distal ends of the stent for the passage of a guide wire. The stent also has an anti-migration device used for immobilization of the stent at the target site.

A tunable stiffness bone rod promotes the healing of fractured bones, such as tibia bones. The tunable stiffness bone rod includes a hexagonal shape that has variable levels of stiffness upon application of an axial force. The axial force will begin a low stiffness movement of the bone rod until a threshold is met. Upon reaching the threshold, the stiffness of the bone rod increases to lessen additional longitudinal movement caused by the axial force on the bone rod.

An intramedullary nail implant for positioning in a bone having a head and a shaft defining an intramedullary canal. The implant includes a distal portion having a shaft extending along a central axis and configured for positioning within the intramedullary canal. A proximal portion extends proximally from the distal portion. The proximal portion defines a contact surface which extends at least in part medially of the central axis such that it is configured to extend within a medial portion of the bone head. A method of implanting the nail is also provided.

Devices, systems, and methods for bone stabilization, especially proximal humeral stabilization. The stabilization system may include a bone plate having an elongated portion extending along a longitudinal axis and an enlarged head portion extending from the elongated portion. The stabilization system may include an intramedullary nail having an upper portion and a lower portion extending from the upper portion, the upper portion and the lower portion including a plurality of holes. A plurality of fasteners may be configured to extend through one or more of the plurality of through holes in the bone plate and/or one or more of the plurality of holes in the intramedullary nail and into the bone. The plate and nail may each be used alone or in combination together to stabilize a fracture in a long bone, such as a humerus.

A combination of a first assembly for guiding resection of a femur and tibia of a knee joint and a second assembly including femoral and tibial knee components. The combination of the first assembly and the second assembly provides optimal placement and positioning of the femoral and tibial knee components to achieve near-normal knee kinematics and tension. The preparation for and placement of the prosthetic knee components provides medial-pivoting kinematics mimicking that of the natural knee thereby promoting improved outcome for the patient.
