摘要:
This application relates generally to impactors. More specifically, this application relates to impactors used in medical procedures such as bone fixation or fusion. In some embodiments, the impactors include features that prevent or reduce the likelihood of over-insertion of an implant within a bone cavity.
摘要:
A system for removing an implant from bone can include a guidepin that can be attached to the implant; an osteotome having a flat, elongate body and a sharp, blade portion for cutting bone; an osteotome guide having a elongate body having a plurality of planar faces and a rectilinear cross-section that corresponds in shape to the rectilinear cross-section of the implant, a lumen extending through the elongate body of the osteotome for receiving the guidepin, and a plurality of channels for receiving the osteotome, wherein one of the plurality of channels is disposed along each one of the plurality of planar faces.
摘要:
This application relates generally to broaches. More specifically, this application relates to broaches used to shape bores in bone. The broaches can shape the bores to receive an implant and also cut additional tubes or channels for receiving bone graft material and/or biologic aids.
摘要:
The present invention relates generally to implants and tools for the fixation or fusion of joints or bone segments. These tools include tissue dilators and protectors. Other tools include broaches used to shape bores in bone. The tools can also include a system for removing an implant from bone. Implants can include assemblies of one or more implant structures that make possible the achievement of diverse interventions involving the fusion and/or stabilization of lumbar and sacral vertebra in a non-invasive manner, with minimal incision, and without the necessitating the removing the intervertebral disc. Implants for fusing both sacroiliac joints of a patient include a long implant that extends across both sacroiliac joints.
摘要:
This application relates generally to guide pins and wires. More specifically, this application relates to guide pins and wires used in medical procedures such as bone fixation or fusion. One embodiment of the guide pin includes a distal end with a ball end cutter. Other embodiments of the guide pin include expandable prongs that can impede further advancement of the guide pin.
摘要:
A threaded implant can be provided with an elongated main body having external threads configured to thread into bone, and an internal support structure located within the external threads. The internal support structure has a helical arrangement that extends in an opposite direction to the external threads. Other threaded implants and methods are also disclosed.
摘要:
The present invention generally relates to bone implants. More specifically, the present invention relates to bone implants used for the fixation or fusion of the sacroiliac joint and/or the spine. For example, a system for fusing or stabilizing a plurality of bones is provided. The system includes an implant structure having stem portion and a head portion, the stem portion having a rectilinear cross sectional area. A tulip or saddle structure can be attached to the head portion, and a rod can be secured within the tulip or saddle structure.
摘要:
Assemblies of one or more implant structures make possible the achievement of diverse interventions involving the fusion and/or stabilization of lumbar and sacral vertebra in a non-invasive manner, with minimal incision, and without the necessitating the removing the intervertebral disc. The representative lumbar spine interventions, which can be performed on adults or children, include, but are not limited to, translaminar lumbar fusion and lumbar facet fusion involving a curved implant structure.
摘要:
A surgical procedure to insert an implant into the body of a patient may impinge upon or run the risk of damaging neural tissue during the insertion procedure. To reduce this risk, the implant and instrumentation used during the implantation procedure can be modified or adapted for use as neuromonitoring probes to determine whether a nerve is in close proximity.
摘要:
Implants for the fusion or fixation of two bone segments are described. For example, the implants can be used for the fusion or fixation of the sacroiliac joint. The implants can include fenestrations, have a rectilinear overall cross-sectional area, and have a curvature. Some implants can also be used to rescue failed implants.
