摘要： An ankle implant for use in ankle arthroplasty in total ankle replacement is provided. The implant includes an upper prosthesis anchored to the tibia and a lower prosthesis anchored to the talus. The lower prosthesis is operable associated with the upper prosthesis. The implant also includes a stem which is rigidly removably connected to the second member. The stem includes a portion for attachment to the calcaneous. The stem is be adapted to be in a first position in the calcaneous when the stem is in a first relative position with respect to the lower prosthesis, and to provide for a second position in the calcaneous when the stem is in a second relative position with respect to the lower prosthesis.

摘要： A bone plate that includes apertures for bone screws and locking screws is disclosed. The locking screws can be in an aperture adjacent to the locking screw aperture such that when the locking bone screws and locking screws are in place, the head of the locking screw at least partially covers the head of the bone screw. In another example, the locking screw aperture is threaded, and the locking screw is placed on top of the bone screw.

摘要： An intramedullary bone fixation device that includes a shaft with a flexible region. The flexible region may be configured to flex from a first shape to a second shape as the shaft moves along a curved medullary canal. For example, the bone fixation device may include a distal bone screw that is configured to move along the curved medullary canal of first and second segments of a fractured bone (e.g., two segments of a broken rib) and fasten to the segment bone segment. The bone fixation device may include a locking member (e.g., a proximal bone screw) that is configured to lock the shaft to the first bone segment. For example, the shaft may be fixed to the distal bone screw and ratchetably coupled to the shaft such that the first and second bone segments can be compressed together by urging together the distal bone screw and the locking member.

摘要： Intramedullary systems, expandable intramedullary nails, expandable anchors, and methods of using the same. The intramedullary system may include an expandable intramedullary nail configured to extend into an intramedullary canal of a long bone and/or one or more expandable anchors configured to extend at an angle transverse to the intramedullary nail. The intramedullary nails and/or anchors may include one or more integrated expansion mechanisms that allow for insertion in a contracted configuration and expansion into a deployed configuration to lock the relative position and prevent axial rotation and translation of the system.

摘要： An intramedullary nail is suggested comprising a nail shaft with a lateral recess, with an expansion element being arranged in that recess, and an adjustment screw for adjusting the position and orientation of the expansion element relative to the nail shaft. A threaded bore may be formed in the nail shaft, wherein the threaded bore extends through the nail shaft and into the recess and is adapted to receive the adjustment screw.

摘要： 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 also has a central lumen open at the proximal and distal ends of the stent for the passage of a guide wire. A method for using the stent and a kit containing the stent are also disclosed.

摘要： A bone implant includes a proximal end, a distal end, a first portion extending between the proximal and distal ends having a maximum and minimum portion height, and a second portion extending between the proximal and distal ends having a maximum and minimum portion height. The second portion is connected to the first portion at the proximal end and the distal end and at least one of the first portion and the second portion is moveable relative to the other of the first portion and the second portion so as to transition the bone implant between a relaxed state wherein the first and second portions are separated by a first distance and a contracted state wherein the first and second portions are separated by a second distance different from the first distance. At least one of the proximal end and the distal end have the minimum portion height.

摘要： Systems for bone fracture repair are disclosed. One system includes a biocompatible putty that may be packed about a bone fracture to provide full loadbearing capabilities within days. The disclosed putties create an osteoconductive scaffold for bone regeneration and degrade over time to harmless resorbable byproducts. Fixation devices for contacting an endosteal wall of an intramedullary (IM) canal of a fractured bone are also disclosed. One such fixation device includes a woven elongated structure fabricated from resorbable polymer filaments. The woven elongated structure has resilient properties that allow the woven structure to be radially compressed and delivered to the IM canal using an insertion tube. When the insertion tube is removed, the woven structure expands towards its relaxed cross-sectional width to engage the endosteal wall. The woven elongated structure is impregnated with a resorbable polymer resin that cures in situ, or in the IM canal.
