Implant and method for long bone fixation
An implant and method for fixation of long bones. The implant provides rotational, longitudinal, and bending stability. The implant comprises one or more elongated members that span the intramedullary cavity of a long bone, a distal tip that expands radially relative to the long axis of the implant, and a locking mechanism at the proximal end of the implant.
Femoral component extractor
The invention is defined by the claims set forth herein; however, briefly, the invention herein is an extractor for a human femoral component with a trunnion neck comprising, a plurality of extractor sections, including a first section with a first axis, a second section with a second axis, and a third section with a third axis; a body with a threaded hole defined therein that is provided with a clamping body section and a central body section, a pivoting member with first end, a second end, and a pivot hole defined thereinbetween that includes a clamping structure located at the second end that is shaped to clamp the trunnion neck of the femoral component; and a pivot that secures the pivoting member to the body by extending through the pivot hole defined in the pivoting member and the pivot hole defined in the fulcrum structure of the body.
ORTHOPEDIC INSTRUMENT ADAPTERS
In general, orthopedic instrument adapters and methods of using orthopedic instrument adapters are provided. In an exemplary embodiment, an adapter is configured to releasably attach to an end effector configured to impact bone. The end effector can be a broach, chisel, or other surgical implement. The adapter includes a spring-loaded hook that is configured to releasably seat in a cut-out formed in the end effector. The adapter is also configured to releasably attach to a surgical impacting tool, such as an orthopedic impactor, configured to drive impacting of the end effector relative to bone.
Cannulated, modular femoral broach and surgical instrument handle
An orthopaedic surgical instrument assembly includes a surgical reamer, a cannulated broach, and an instrument handle. The broach includes a bore sized to slide over a shaft of the reamer. The handle attaches to the broach and also includes a bore sized to slide over a shaft of the reamer. A modular broach assembled from a number of broach segments may be used. Methods associated with the surgical instrument assembly are also disclosed.
Shoulder prosthesis components and assemblies
An inserter includes a first end, a second end, and a body extending between the first end and the second end. A first impacting surface is disposed at the first end, and a second impacting surface is disposed adjacent to the second end. An interface disposed at the second end and is configured to engage an implant. The first impacting surface is configured to direct a first impacting force along the body of the inserter in a first direction, and the second impacting surface is configured to direct a second impacting force along the body in a second direction that is different from the first direction. Methods of use also are disclosed.
Press fit stem
A method of implanting a medical implant comprises the steps of reaming a tapered bore to a first depth and a counter bore, coaxial to the tapered bore, to a second depth less than the first depth in a long bone. The counter bore has a larger diameter than the tapered bore. The method further includes inserting a medical implant into the tapered bore and counter bore. The medical implant includes a stem and a collar disposed around a portion of the stem. Inserting the medical implant include fully seating a portion of the stem into the tapered bore to form a press-fit between the stem and the long bone. The collar may be moved into the counter bore to a depth less than the second depth.
METHOD AND APPARATUS FOR PREPARING AND IMPLANTATION OF MEDICAL IMPLANTS
An apparatus for implanting a medical implant into bone includes: an implant having at least one predetermined natural frequency; and an instrument, comprising: a housing; a coupler carried by the housing and configured to be mechanically connected to a medical implant; and a forcing mechanism carried by the housing and operable to apply a cyclic excitation force at the predetermined natural frequency.
SHOULDER PROSTHESIS COMPONENTS AND ASSEMBLIES
Various embodiments disclosed herein relate to stemmed and stemless humeral anchors for use in shoulder arthroplasty procedures. For example, the humeral anchor can include a first end, a second end, and an interior surface extending between the first end and the second end. The interior surface can be disposed about a recess disposed between the first end and the second end. The recess can be configured to secure a coupling of a shoulder articular body directly to the interior surface.
SYSTEM AND METHOD FOR ALTERING ROTATIONAL ALIGNMENT OF BONE SECTIONS
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.
Suprapatellar insertion system, kit and method
A system is provided for inserting and securing, through a suprapatellar region of a leg, a nail into a medullary canal of a bone. The system can include a flexible sleeve configured to be partially inserted in the leg. The flexible sleeve can define a leading end and a trailing end spaced apart from the leading end along a first axis. The flexible sleeve can define a first cannulation that extends along the first axis between the leading and trailing ends. The first cannulation can be sized to receive therethrough at least the intramedullary nail. The system can further include a retaining member configured support at least a portion of the flexible sleeve. The retaining member can be configured to position the flexible sleeve through the suprapatellar region of the leg such that the flexible sleeve leading end is aligned with the proximal end of the bone. The intramedullary nail can be insertable through the flexible sleeve and into the medullary canal.
