A device for positioning an orthopaedic fixation device includes: a compression attachment mechanism; a fastener guide coupled to the compression attachment mechanism; and a spring member disposed in the fastener guide. The compression attachment mechanism is biased toward a closed position and comprises a gripping portion that is movable by a user for transitioning the compression attachment mechanism from the closed position toward an open position for loading a plate onto the compression attachment mechanism.

Implant positioning devices and methods

A ratchet fastener includes a base including a fastening portion including threads and a ratchet portion including teeth and a ratchet wheel disposed in mating arrangement with the teeth. The ratchet fastener is configured to receive a tether. The ratchet wheel is configured to be rotated to tighten the tether.

Orthopaedic fixation devices, systems and methods

An implantable fixation device for rejoining opposed portions of a separated bone. The device including two corresponding plates that are configured to be aligned and coupled to a bone, such as a sternum, pre-resection of the bone or prior to cutting/separating the bone. The placement of the corresponding plates provides a gap between the edges of the plates that face one another allowing for and guiding a cutting tool for separating the bone. After the bone has been cut and the desired surgical procedure performed, the plates also assist in realigning and fixation of the bone portions. At least one plate includes a ratchet mechanism that is configured to tighten a locking element and draw the two plates together and into alignment with one another.

Orthopaedic fixation device, system and method

An implant positioning device including a guide and holder for fasteners used in orthopaedic fixation for use in affixing a plate-like member to a bone or other part of a patient. The guide and holder includes a base adapted to align with the plate in a manner to orient fasteners with the plate for fixation. A plurality of fastener holders are on the base and adapted to releasably hold a fastener in a manner where the fastener is exposed at a proximal end for access by a fastener driver and aligned at a distal end with an aperture on the plate through which the fastener is to be driven.

A computer assisted surgery (CAS) system and method for preparing an anatomical structure to receive an orthopaedic implant. The method generally involves the steps of determining a contour of the anatomical structure by using the CAS system to acquire a plurality of points on the anatomical structure and provide a best fit approximation of the anatomical structure based on the plurality of points, selecting an implant to replicate the anatomical structure, and preparing the anatomical structure to receive the implant.

The present disclosure relates to devices that aid a user in ceasing bruxism. The devices may be placed between a user's teeth, such as during sleep, and alert the user when the user clenches his/her teeth. In an aspect, a device includes a housing containing a battery power source, a vibration device, and an electrical contact mechanism having a movable element which closes a circuit to actuate the vibration device. A disk-shaped portion adapted to be emplaced in a person's mouth between a cheek and adjacent teeth is disposed around the housing. A resilient bite portion extends from the housing and is adapted to be emplaced between upper and lower teeth. A compressible element is disposed in the bite portion and causes the movable element of the electrical contact to close to actuate the vibration device in response to compression of the bite portion.

A slap hammer tool and associated instrumentation to engage with the slap hammer tool are disclosed herein. In some examples, a slap hammer tool including an end adapted for engagement with a quick release connector of an instrument is provided. The instrument can be adapted to receive the distal end of the slap hammer for engagement, the engagement being provided through rotation of the slap hammer relative to the instrument. Once the slap hammer and instrument are engageably coupled, the slap hammer can be used to provide force and accompanying motion away from the instrument in the direction of the slap hammer instrument. Force can be provided by the slap hammer tool to a coupled instrument, for example, to move or extract the coupled instrument from placement on a surgical area.

Engageable slaphammer tool and instrumentation

An orthopedic guide for preparing a particular patient's bone to receive a prosthesis using a milling tool with a rotating burr comprises a platform having a top surface and a bottom surface adapted to face the patient's bone. The platform defines an elongate milling track that extends through the platform from the top surface to the bottom surface of the platform, the milling track being sized and shaped so as to be adapted to guide the milling tool across the patient's bone with the burr of the milling tool rotating beneath the bottom surface of the platform to be adapted to remove a first bone portion from the patient's bone. A plurality of legs are coupled to the platform and each comprise a referencing end that is contour-matching fabricated as a function of the patient's bone data to be adapted to abut the patient's bone, the referencing ends of the plurality of legs adapted to cooperate to locate the orthopedic guide at a single predetermined location of the patient's bone.

Patient-specific mill guide

The present disclosure relates to systems and methods for preparing a distal end of a femur for receiving a knee prosthesis. A method can include installing a valgus guide onto an intermedullary rod, coupling a drill guide with said valgus guide, resting a boom tip of said drill guide on a high part of the femur, drilling a hole into a distal portion of a medial condyle using a first drill hole of said drill guide and drilling a hole into a distal portion of a lateral condyle using a second drill hole of said drill guide, and, subsequent to drilling the first and second drill holes, resecting the distal portion of the medial condyle of the femur and the distal portion of the lateral condyle of the femur. A system can include a valgus guide, a drill guide, and a resection tower, among other things.

Distal resection systems and methods

Various embodiments of femoral trochlea prostheses useable in a knee joint. The knee joint includes a patella and a distal femur with a femoral trochlea, or patello-femoral groove. In one embodiment, a femoral trochlea prosthesis includes a distal tail. In another embodiment, a femoral trochlea prosthesis includes a wing or extension portion. In yet another embodiment, a set of femoral trochlea prostheses includes a plurality of prostheses having differing thicknesses. In still another embodiment, a femoral trochlea prosthesis includes a porous medium on various portions of the prosthesis.
