Stand alone intervertebral fusion device
An angled fixation device, such as an angled screw. This angled fixation device may be used by the surgeon to secure a spacer to a spinal disc space. The proximal end portion of the angled fixation device is driven perpendicular to the anterior wall of the spacer, and so is parallel to the vertebral endplates and in-line with the inserter. The distal end portion of the angled fixation device is oriented at about a 45 degree angle (plus or minus 30 degrees) to the vertebral endplate it enters.
Variable thickness femoral augments
A femoral assembly includes a femoral component that includes condylar portions and an anterior flange portion. The condylar portions and anterior flange portion together define an outer side of the femoral component for articulating with a tibial prosthesis and an inner bone facing side opposite the outer side. The inner bone facing side defines five intersecting component inner surfaces that each extend from a lateral side of the femoral component to a medial side thereof. A femoral augment includes condylar portions and an anterior flange portion. The condylar portions and anterior flange portion together define an outer side of the femoral augment comprised of five intersecting augment outer surfaces and an inner side comprising no more than three intersecting augment inner surfaces. The augment outer surfaces correspond to the component inner surfaces of the femoral component. The augment inner surfaces correspond to resected surfaces of a distal femur.
OFFSET ADAPTER UNIT
The present invention relates to an implant playing a role as a joint in coupling a revision implant in revision total knee arthroplasty and, more specifically, to an offset adapter unit comprising an adapter which couples a femoral member or a tibial member to a stem member in revision total knee arthroplasty; and a nut coupled to the adapter, thereby improving the strength by considering fracture occurring in the narrowest area.
EXPANDABLE INTERVERTEBRAL CAGE ASSEMBLIES
An expandable assembly for insertion into an intervertebral space is presented. The assembly, in particular aspects, includes an elongate body comprising an upper portion and a lower portion. The assembly may include an expander that is sized and shaped for insertion between the upper portion and lower portion, thereby selectively expanding the upper portion away from the lower portion. The elongate body may also include one or more bone graft windows.
System and method for preparing a patient's femur in an orthopaedic joint replacement procedure
An orthopaedic joint replacement system is shown and described. The system includes a number of prosthetic components configured to be implanted into a patient's knee. The system also includes a number of surgical instruments configured for use in preparing the bones of the patient's knee to receive the implants. A method or technique for using the surgical instruments to prepare the bones is also disclosed.
Pad for acetabular bone revision and reconstruction and fixing structure for pad and acetabular cup prosthesis
The present disclosure relates to the field of medical instruments, in particular to a pad for acetabular bone revision and reconstruction and a fixing structure for a pad and an acetabular cup prosthesis. The pad is located between an acetabular cup prosthesis and the acetabular bone, and is connected to the acetabular cup prosthesis and the acetabular bone respectively. The pad includes a first component and a second component which has the same or different radius and shape as or from the radius and shape of the first component; the first component is movably connected with the second component; and the shape of the connected first component and second component is matched with a defective part of the acetabular bone.
Reciprocating rasps for use in an orthopaedic surgical procedure
Reciprocating rasps for the surgical preparation of the bone prior to the implantation of a glenoid or acetabular component with complex geometry are disclosed. Surgical methods for the use of such reciprocating rasps are also disclosed.
PATIENT-SPECIFIC AUGMENTS
A patient-specific augment can be attached to an implant component for a bone of a joint of a patient. The patient-specific augment has first and second surfaces. The first surface is a three-dimensional patient-specific surface that closely matches and can mate to a substantially unaltered and unresected surface of a bone defect of the specific patient only in one position. The second surface is designed to engage a non-custom surface of the implant.
HUMERAL TRAYS WITH TUBEROSITY AUGMENTS SUFFICIENTLY DESIGNED TO IMPROVE JOINT MECHANICS
Disclosed is a prosthetic augment designed to reconstruct a lateral tuberosity shape of a humerus in a subject having proximal bone loss that includes a humeral adapter tray configured to connect a humeral liner of a reverse shoulder prosthesis to a humeral stem of the reverse shoulder prosthesis and an augment member having a first face adapted for contacting the humeral stem of the reverse shoulder prosthesis and a second face adapted for contacting an underside of a muscle, wherein at least a portion of the second face includes a bulbous surface adapted to alter a wrapping angle of the muscle around the lateral tuberosity, and wherein the second face has a radius of curvature selected from one of a constant radius of curvature or a variable radius of curvature.
METHOD AND SYSTEM INCLUDING SLEEVES AND BROACHES FOR SURGICALLY PREPARING THE PATIENT'S BONE
An orthopaedic surgical instrument system includes a first broach including a first end configured to be separately secured to a handle and a tapered body having a plurality of cutting teeth defined therein, and a second broach including a first end configured to be separately secured to the handle in place of the first broach, a first tapered body extending distally from a second end positioned opposite the first end, and a second tapered body extending distally from the first tapered body. The tapered body of the first broach and the first tapered body of the second broach have a first outer geometry and the second tapered body has a second outer geometry different from the first outer geometry.
