Method of using a femoral surgical instrument
A method of using an orthopedic surgical instrument assembly that includes an instrument handle configured to clamp a broach and femoral stem trial assembly. A depth stop is configured to removably couple to the instrument handle. When the broach and femoral stem trial are advanced into a medullary canal of a patient's femur, a substantially planar proximal surface of the depth stop is configured to engage the distal surface of the femur, determining the depth of the broach in the medullary canal. The proximal surface of the depth stop is parallel to the joint line, defining an oblique angle to the anatomical axis of the femur. The depth stop may be attached to the instrument handle at a number of positions to control the depth of the broach. The assembly may include a spacer plate removably coupled to the depth stop that distalizes the broach in the medullary canal.
THREADED TARGETING INSTRUMENTS, SYSTEMS AND METHODS OF USE
Instruments, implants, bone plates, systems and methods for correcting bone deformities and fractures in the lower extremity are disclosed. Specifically, targeting instruments, implants, bone plates, systems and methods used for correcting bone deformities and/or fractures in the foot using compression are disclosed.
INTERNAL OSSEOINTEGRATED IMPLANT FOR TRANSFEMORAL AMPUTEE
The present invention is an internal osseointegrated transfemoral amputee implant device and related methods. The device is designed to restore the enclosed nature of the bone marrow system which is disrupted by amputation, plus provide a pressure tolerant (weight-bearing) surface and mechanical anchoring for the iliotibial band.
ORTHOPEDIC DRILL GUIDE SYSTEM WITH LATERAL EDGE GUIDANCE, AND METHOD OF SURGERY FOR USE THEREWITH
The invention comprises a medical implant system with implant having a fastener hole for a fastener and further including a fusion screw, positioned to avoid interference with the implant fastener. The medical implant system also includes a guide that is mounted in the fastener hole and from an edge of the implant which provides for defined adjustability for angulation, and optionally depth, to allow for placement of the fusion screw so as to avoid impingement with the implant and the fasteners that secure it in place. The invention also relates to a method of surgery using the system.
Knee instruments and methods
Knee arthroplasty instrument systems directly reference and align with the anterior distal femoral cortex and the mechanical axis of the leg. The anterior femoral resection is aligned in the same plane as the anterior distal femoral cortex. The center of the femoral head, the medial/lateral center of the distal femur, the medial/lateral center of the proximal tibia, and the second toe, medial/lateral center of the ankle, or anterior tibial spine are all aligned to the mechanical axis of the leg. Methods of using a cut guide assembly and referencing a provisional proximal tibial resection at the base of the tibial eminence are disclosed.
Guidance system and method for bone fusion
An apparatus comprises a medial rail having a plurality of openings through the medial rail for receiving pins, screws or wires. An arm is pivotally mounted to the medial rail. The arm has at least a first track on a first side. A post has a connector slidably mounted to the first track of the arm for movement along the first track. A guide is slidably mounted for movement along the post. The guide has at least one opening through it and at least one pin for engaging a bone of a patient.
Method for performing surgical procedures using optical cutting guides
A method for performing a surgical procedure on a patient using a robotic system and a navigation system. The robotic system includes a cutting tool. The navigation system has at least one locating device to track a portion of the patient during the surgical procedure. The navigation system provides information as to a position of the portion of the patient. An optical cutting guide is projected onto the portion of the patient to enable cutting of the portion of the patient with the cutting tool of the robotic system while the optical cutting guide is projected onto the portion of the patient.
Alignment guide apparatus, methods and systems
The present invention discloses an alignment guide apparatus, system, and method. The alignment guide apparatus includes a body, a fixation insert, a guide pin, and a screw. The body may include an arm with a first end and a second end, an attachment portion at the first end, and an alignment portion at the second end. The fixation insert may be configured to pass through the attachment portion and the guide pin may be configured to pass through the alignment portion. The screw may be configured to engage the guide pin. The alignment system may include a bone plate, an alignment guide, a screw, at least one first fastener, and at least one second fastener. A method for moving a joint is also disclosed.
Systems and methods for intramedullary preparations
A system for intramedullary preparations comprises a directional reamer including a flexible drive shaft having a proximal end and a distal end, and a cutting head operably connected to the distal end of the flexible drive shaft. The system further includes a means of displacing the distal end of the flexible drive shaft and deflecting the cutting head to selectively shape a medullary canal in a bone. A follower sleeve is also include in the system and has a proximal end and a distal end in the form of a collar, with the follower sleeve being configured to accept the flexible drive shaft. The system additionally includes a reaming plunger that extends through the follower sleeve and is positioned adjacent to the flexible drive shaft such that the reaming plunger engages the collar of the follower sleeve to deflect the cutting head.
System and method of coupling an alignment guide to an intramedullary nail insertion handle
In one example, a system has an insertion handle that can be coupled to an intramedullary nail and includes a first coupler that defines one of a recess and a projection, and one of a latch and an abutment surface. The system has an aiming guide that includes a guide body that defines at least one alignment aperture therethrough. The aiming guide includes a second coupler that can couple the guide body to the first coupler such that the at least one alignment aperture is positioned to guide an instrument towards at least one bone-anchor fixation hole of the intramedullary nail. The second coupler defines another of the recess and the projection, and another of the latch and the abutment surface. The first and second couplers can couple to one another by receiving the projection in the recess and by engaging the latch with the abutment surface.
