Reconfigurable hip prosthesis, method of use and kit
Disclosed is a reconfigurable hip joint prosthesis and elements therefor which is adapted to be surgically implantable in a human body, a part in the upper femur, another part in the pelvis. The implantable prosthesis may be configured in a reversible manner, and provide alternative configurations as may be desired or necessary. The present invention also includes a method of implanting into a human body a prosthesis as described herein, and subsequently reconfiguring the prosthesis as may be desired or necessary. A still further aspect of the invention is a kit of component parts used in providing a configured implantable prosthesis.
Hip joint device, system and method
An implantable medical device for implantation in a hip joint is provided. The medical device comprises: at least one artificial hip joint surface adapted to replace at least the surface of at least one of the caput femur and acetabulum. At least one artificial hip joint surface comprises: a positioning hole with at least one opening in said at least one artificial hip joint surface. The hole is adapted to be placed and dimensioned such that the medical device is adapted to be fitted using a positioning shaft and at least partly surround the shaft, for positioning the at least one artificial hip joint surface in a desired position in the hip joint. The hole is adapted to be fitted using the positioning shaft, when the shaft is stabilized and placed in at least one of the femoral bone and the pelvic bone for positioning said medical device inside the hip joint.
COMBINATION INTRA-MEDULLARY AND EXTRA-MEDULLARY FRACTURE STABILIZATION WITH ALIGNING ARM
A device provides a variety of fracture fixation options should a fracture occur after total hip arthroplasty or total knee arthroplasty, and provides associated methods and apparatus for application of provided fixation. The ability to pre-engineer fracture fixation contingent solutions into femoral or tibial components provides for a distinct clinical advantage in the planning and execution for periprosthetic fracture fixation. Said methods and apparatus include targeting devices which allow for intimate association of fixed angle locking screws in pre-drilled holes in an existing prosthetic, femoral nail, or other components including additional fixation components. Such apparatus and methods further include the use of alignment devices and other components to allow for ease of repair of fractures utilizing the pre-engineered solutions.
Hip joint device and method
A medical device for implantation in a hip joint of a human patient is provided. The natural hip joint having a ball shaped caput femur as the proximal part of the femoral bone with a convex hip joint surface towards the centre of the hip joint and a bowl shaped acetabulum as part of the pelvic bone with a concave hip joint surface towards the centre of the hip joint. The caput femur has a centrally placed longitudinal extension, extending through the center of the caput and collum femur, aligned with the collum femur, defined as the caput and collum femur center axis. The medical device comprising; an artificial acetabulum, comprising a concave surface towards the centre of the hip joint. The artificial concave acetabulum is adapted to, when implanted, be fixated to the femoral bone of the human patient, and be in movable connection with an artificial caput femur fixated to the pelvic bone of the patient.
Hip implant system
Hip implant systems described herein can include a distal stem, a proximal body, and a fastener. In some embodiments, the distal stem can include a cavity configured to receive the fastener when a portion of the distal stem is positioned within the proximal body. In some embodiments, the distal stem can include a threaded exterior surface configured to mate with a fastener when a portion of the distal stem is positioned within the proximal body. In some embodiments, a distal end of the distal stem can include an anterior relief configured to conform to interior surface of a femoral canal of a patient.
Orthopaedic prosthesis having support structure
A femoral orthopaedic prosthesis includes a metallic core extending from a proximal end to a distal tip. The metallic core includes a neck that is positioned at the proximal end and is configured to receive a prosthetic femoral ball. An elongated stem extends distally from the neck to the distal tip. The stem includes a proximal section extending distally from the neck, and a distal section that extends proximally from the distal tip. The elongated stem also includes a pair of spaced-apart beams that connect the proximal section to the distal section. An aperture is defined in the stem between the pair of spaced apart beams.
