摘要： An orthopedic prosthesis for implantation into a bone of a patient includes a porous metal shell adapted to be affixed within the bone. The porous metal shell includes an outer surface adapted to receive bone ingrowth and an inner surface adapted to engage a liner. The porous metal shell is porous from the outer surface to the inner surface. A non-porous member may be affixed to the porous metal shell. The non-porous member may include a piercing member extending from the outer surface, the piercing member adapted to penetrate the bone in an implanted position. The non-porous member may include spikes or fins. In one example, the piercing member may define a reduced material cross section at an interface with the outer surface of the porous metal shell. The piercing member may be adapted to be broken at the reduced material cross section and removed from the porous metal shell.

摘要： A system for replacing a portion of a hip joint can include a cup having an outer surface and an inner surface. A bearing can include an outer bearing surface and an inner articulating surface. The outer bearing surface can be positioned adjacent to the cup. A ring can be selectively disposed between the cup and the bearing. The ring can define an annular body having a slit formed therein. A removal tool can define a proximal end and a distal end. The distal end can define a ring engaging surface and a bearing engaging surface. The ring engaging surface can be adapted to engage the ring at the slit such that the ring expands radially from a locked position away from engagement with the bearing to an unlocked position. The bearing engaging surface can be adapted to engage the bearing and urge the bearing away from the cup.

摘要： Methods and devices for assessing and determining proper alignment and placement of implant components during joint reconstruction surgery, particularly in the knee joint. Provisional components with force transducers 150, 240 are positioned in the joint 40 and used to determine the precise forces and decide how to balance the forces in the joint. In the knee joint, a provisional tibial component 80 and a provisional patella component 85 are used. The tibial component has a base member 84 and a pair of bearing elements 88, 90 held loosely in place by a clamping frame 86. Rocker members 130, 132 allow the bearing elements to move or rock relative to the base member. The patella component has a base plate 220 and a bearing element 222 held loosely in place by a plurality of pins 228. A rocker member 232 allows the bearing element to move or rock relative to the base plate. Force transducers or sensors 150, 240 connected to computers are positioned in the provisional components 80, 85 and provide readings of the location and magnitude of the sum of the forces generated in the joint when the joint is moved through its range of motion.

摘要： A patient-specific acetabular resection guide includes a dome-shaped surface bounded by a periphery. The dome-shaped surface is a three-dimensional patient-specific surface designed to anatomically match and be received into an acetabulum of the patient, based on a three-dimensional image of a hip joint of the patient reconstructed from a medical scan of the hip joint. The resection guide includes a plurality of guiding formations defined on the resection guide and having patient-specific shapes and orientations for guiding corresponding osteotomies relative to the acetabulum for correcting hip dysplasia.
