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： An orthopedic prosthesis for implantation into a bone of a patient can include a shell, an augment and a securing member. The shell can be adapted to be affixed within the bone and have an outer surface adapted to receive bone ingrowth after implantation. The shell can have an inner surface adapted to engage a liner. An elongated slot can extend between the outer and inner surfaces of the shell. The augment can define a body and have a passage therethrough. The securing member can extend through the passage and the slot. The securing member can be movable between a locked position wherein the augment is precluded from relative movement with the shell and an unlocked position wherein the securing member is adapted to slidably traverse along the slot to locate the augment at a plurality of positions relative to the shell.

摘要： A method for removing a bearing that is coupled to a prosthetic implant by a ring includes advancing a distal end of a removal tool in a first direction and into a slit formed in the ring. The ring can be caused to expand radially from engagement with the bearing. The distal end of the removal tool can be advanced in a second direction such that the removal tool engages the bearing. The distal end of the removal tool can be further advanced in the second direction such that the removal tool urges the bearing away from the prosthetic implant.

摘要： A broach instrument for preparing the proximal medullary canal of a femur for receiving a hip stem implant includes lateral and medial broach segments that may be assembled and disassembled along a longitudinal plane of separation defined by longitudinal sliding surfaces. A respective longitudinal shaft is connected to a proximal end of each broach segment. Each longitudinal shaft has a respective impact head connected to a respective proximal end. The broach segments and/or shafts positively engage one another to resist lateral separation of the broach segments. Each broach segment may be inserted separately and sequentially through a minimal posterior incision and through the gluteus maximus and then be assembled within the patient for broaching.

摘要： A method of imaging a body part includes locating a first, second and third anatomical reference area. The third anatomical reference area is disposed generally between the first and second anatomical reference areas. Furthermore, the method includes positioning a first member of a reference tool relative to the first anatomical reference area, positioning a second member of the reference tool relative to the second anatomical reference area, and a pivotal coupling member relative to the third anatomical reference area. The pivotal coupling member pivotally couples the first and second members of the reference tool. In addition, the method includes imaging a target area of the body part to produce an image. The image includes the target area of the body part and the first and second members. The first member indicates a first axis of the body part, and the second member indicates a second axis of the body part.

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.

摘要： A system for replacing a portion of a shoulder joint can include a tray having an outer surface and an inner surface. The outer surface can be adapted to engage a humeral stem. A bearing can include an outer bearing surface and an inner articulating surface. The outer bearing surface can be positioned adjacent to the tray. A ring can be selectively disposed between the tray and the bearing. The ring can define an annular body having a slit formed therein. The ring can be movable between a locked position wherein the ring retains the bearing relative to the tray and an unlocked position. 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 the locked position away from engagement with the bearing to the unlocked position. The bearing engaging surface can be adapted to engage the bearing and urge the bearing away from the tray.
