This disclosure relates to reaming assemblies and methods for repairing bone defects. The reaming assemblies disclosed herein may be utilized for removing bone prior to positioning a graft and/or implant at a surgical site.

A single-use handle is configured to attach to a working shaft that can support a sounder for measuring the medullary canal of a proximal radius, and a planarizer that is configured to planarize a proximal edge of the proximal radius after the proximal radius has been resected. The handle can further include a plurality of sizing cavities that are configured to receive the resected bone so as to determine the size of the resected bone. The handle can further include an ejector that is configured to decouple the planarizer from the working shaft.

A method of treating a hip joint of a human patient using a pelvic drill comprising a driving member, a bone contacting and an operating device for operating said driving member. The method comprise the steps of creating a hole passing through the pelvic bone and into the hip joint of the human patient, and providing at least one hip joint surface to the hip joint, through said hole in the pelvic bone of the human patient. In one embodiment the method includes inserting a needle or tube like instrument into the patient's body for filling a part of the patient's body with gas and thereby expanding a cavity within the body.

Improved systems, methods, and devices for performing joint arthroplasty, including patient-adapted implant components and tools, as well as intraoperative measurement and optimization of joint kinematics are disclosed herein.

A retrograde cutting instrument and method of retrograde drilling using such an instrument. A method of forming a socket includes providing a retrograde cutter, inserting the cutter into a joint with a blade of the cutter in a straight position, pivoting the blade to a non-straight flip position, locking the blade in the flip position, and retrograde drilling a socket using the blade in the flip position.

A method of implant a knee prosthesis includes forming a bone void at an end of a bone, implanting a void filler in the bone void, and implanting a knee prosthesis onto the end of the bone so that a stem of the knee prosthesis is received by the void filler.

A method of implant a knee prosthesis includes forming a bone void at an end of a bone, implanting a void filler in the bone void, and implanting a knee prosthesis onto the end of the bone so that a stem of the knee prosthesis is received by the void filler.

A tibial plateau leveling osteotomy (TPLO) system is provided for surgical correction of a stifle joint of an animal. The system includes a bone plate, fixed angle locking screw, compression screw, and a K-wire. The bone plate includes first surface and a second surfaces having common structure such that each can be positioned against the bone. The plate has a first shaft portion with a dynamic compression screw hole having a major length both extending along a first axis, and second shaft portion with a second axis and K-wire slot defining a major axis angled relative to the second axis but parallel to the first axis. The locking screw has double lead threads and the threaded holes in the plate have quad-lead threads.

A retrograde cutting instrument and method of retrograde drilling using such an instrument. A method of forming a socket includes providing a retrograde cutter, inserting the cutter into a joint with a blade of the cutter in a straight position, pivoting the blade to a non-straight flip position, locking the blade in the flip position, and retrograde drilling a socket using the blade in the flip position.

An expandable implant system is configured to increase the height of a target bone, for instance that has been subjected to a compression fracture. The expandable implant system includes an implant assembly that can be inserted into the target bone, and subsequently expanded so as to increase the height of the target bone. The expandable implant system further includes an and insertion assembly that is configured to create an insertion channel into the target bone, such that the implant assembly can be inserted in a collapsed configuration into the target bone along the insertion channel, and subsequently expanded.
