BONE REPOSITIONING GUIDE SYSTEM AND PROCEDURE
A surgical system and procedure are provided for correcting a deformity between first and second bones using an alignment guide based on a correction factor. The alignment guide is used to insert one or more k-wires into each of the first and second bones in a deformed configuration. A correction guide is passed along the k-wires to rotate and/or translate the first bone relative to the second bone into the corrected configuration. An auxiliary correction guide can be passed along the k-wires to further rotate and/or translate the first bone relative to the second bone from the corrected configuration to an adjusted configuration.
Orthopedic plate with modular peg and compression screw
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.
COMPRESSION DEVICE, KIT, AND METHOD
A compression device made of a superelastic material having a peripheral portion with an upper surface, a lower surface, and a central opening extending therethrough is provided. One or more resilient teeth project inward of the peripheral portion into the central opening and are configured to exert a biasing force in an axial direction when deformed in a direction opposite the axial direction.
SYSTEM AND METHOD FOR JOINING BONEY STRUCTURES
Disclosed are system and methods that use at least one non-threaded anchor and an implant with at least one aperture to join boney structures, where the interaction of the head of the anchor with the implant aperture causes the anchor to move transversely with respect to an initial trajectory. This movement causes compression or distraction of the boney structures which are coupled to the anchors.
ORTHOPEDIC FIXATION SYSTEMS AND METHODS OF USE THEREOF
An orthopedic fixation system includes an implant transitionable between a natural shape and an insertion shape and an implant retainer. The implant includes a transition section deformable to move the implant between the natural shape and the insertion shape. The implant includes a first post and a second post protruding therefrom across the transition section. The first post and second post each include an opening therethrough, whereby, when the implant resides in the insertion shape, the opening of the first post and the opening of the second post align. The implant retainer being configured to insert in the openings of the first and second posts when the implant resides in the insertion shape such that the implant retainer interconnects the first post and second post while spanning the transition section, thereby constraining the implant in the insertion shape.
SYSTEM AND METHOD FOR JOINING BONEY STRUCTURES
Disclosed are system and methods that use at least one non-threaded anchor and an implant with at least one aperture to join boney structures, where the interaction of the head of the anchor with the implant aperture causes the anchor to move transversely with respect to an initial trajectory. This movement causes compression or distraction of the boney structures which are coupled to the anchors.
Bone plate internal fixator device
The present invention relates to a bone plate internal fixator device (101; 501; 701) for epiphysiodesis, comprising a pair of holding elements (102, 103; 502, 503; 702, 703), each one of the holding elements (102, 103; 502,503; 702, 703) respectively comprising a through hole (104, 105; 504, 505; 704, 705) configured for receiving a respective fixing screw (301) to a bone; the bone plate internal fixator device (101; 501; 701) further comprises a central portion (106; 506; 706) which structurally connects and constrains the holding elements (102, 103; 502, 503; 702, 703) with each other; the central portion (106; 506; 706) is flexible so as to allow flexing of the bone plate (101; 501; 701); each said through hole (104, 105; 504, 505; 704, 705) comprises a threaded surface (108, 109; 508, 509; 708, 709) adapted to couple with a corresponding surface (304) of the respective fixing screw (301); the holding elements (102, 103; 502, 503; 702, 703) and the central portion (106; 506; 706) are provided as a composite structure.
BONE REDUCTIONAND PLATE FIXATION FORCEPS
A bone reduction and plate fixation forceps including a first arm having a proximal part including a handle and a bifurcated distal part in which a first bone engaging jaw and second bone engaging jaw are configured to engage a first surface of a fractured bone on each side of the fracture, and a second arm having a proximal part including a handle and a distal part comprising a third bone engaging jaw configured to engage a second surface of the fractured bone to clamp the bone between the first and second arm. At least one of the first bone engaging jaws and second bone engaging jaws has a proximal to distal bridge shape.
MEDICAL DEVICE, SURGICAL KIT AND A METHOD FOR PERFORMING OSTEOTOMY
A surgical kit and a method for performing osteotomy is disclosed. The surgical kit comprises at least two lateral plates and a central plate. The two lateral plates are scaled and fixed over a surgical bone adjacent to each other with an exact distance measured by the scaled lateral plates while the central plate is over two lateral plates to maintain the alignment. The distance is equal to the shortening amount of bone based on the pre-operative measurements. The central plate slides laterally over the two lateral plates to expose the surgical site of the bone. Shortening osteotomy is performed to shorten the bone equal to the distance between the two lateral plates. The central plate then laterally slides over the two lateral plates to achieve the anatomic alignment. Further, the central plate and the two lateral plates are securely fixed to the bone using one or more fasteners.
SYSTEMS AND PROCESSES FOR DISTRACTION CONTROL
A distraction system can include a distraction implant comprising a magnetic element and a distraction mechanism configured to expand the distraction implant in response to rotation of the magnetic element. The distraction system can include an external device comprising a motor configured to rotate a driver magnet while in a powered state, the driver magnet configured to rotate the magnetic element, a computing device configured. The computing device can be configured to measure an electrical current drawn by the motor during rotation of the driver magnet. The computing device can be configured to maintain the motor in the powered state in response to a mean value of the electrical current being greater than or equal to a mean value threshold, and a standard deviation value of the electrical current being less than or equal to a standard deviation threshold.
