摘要： A surgical apparatus comprising a first distraction mechanism, a second distraction mechanism, and a third distraction mechanism. The surgical apparatus is configured to be placed in a joint of the musculoskeletal system to precisely separate the first bone from the second bone to support one or more bone cuts for installing a prosthetic joint. The first distraction mechanism simultaneously changes a height of a first side and a second side of the joint. The change in height is equal on the first and second sides. The second distraction mechanism changes the height on the first side of the joint but not the second side. The third distraction mechanism changes the height of the second side of the joint but not the first side. The surgical apparatus further includes at least one module to measure loading applied by the joint to the surgical apparatus.

摘要： A surgical apparatus configured to be placed in the musculoskeletal system to precisely separate a first bone from a second bone. The surgical apparatus has one or more sensors to measure one or more parameters and supports one or more bone cuts for installing a prosthetic component. The surgical apparatus has three distraction mechanisms configured to increase or decrease a height between a first support structure and a second support structure. A tilt mechanism comprises at least one of the three distraction mechanisms. Each distraction mechanism is supported by at least two guide shafts such that movement of each distraction mechanism is aligned by the corresponding at least two guide shafts and loading is supported by the corresponding at least two guide shafts.

The surgical apparatus has one or more sensors to measure one or more parameters and supports one or more bone cuts for installing a prosthetic component. The surgical apparatus has three distraction mechanisms configured to increase or decrease a height between a first support structure and a second support structure. The tilt mechanism adjusts the tilt between the first support structure relative to the second support structure. The tilt mechanism of the surgical apparatus is adjusted from a first tilt to a second tilt to support a bone cut on one of the first or second bones.

摘要： A system is disclosed to support installation of a prosthetic joint or a prosthetic component. The system includes at least one sensor to measure a parameter. The system uses one or more patient specific instruments in conjunction with a tensor to make one or more bone cuts. The patient specific instruments and tensor make the bone cuts such that an installed prosthetic joint is aligned, balanced, loaded correctly, and positioned optimally for performance and reliability. The use of the tensor simplifies the workflow required when using the patient specific instruments. In one embodiment, the patient specific instruments are bone cutting jigs configured for the patient anatomy.

摘要： A surgical apparatus configured to be placed in the musculoskeletal system to precisely separate a first bone from a second bone. The surgical apparatus has one or more sensors to measure one or more parameters and supports one or more bone cuts for installing a prosthetic component. The surgical apparatus has at least one distraction mechanism configured to increase or decrease a height between a first support structure and a second support structure. A tilt mechanism comprises the at least one distraction mechanism. The tilt mechanism couples through a first pivot point and a second pivot point and adjusts a tilt of the second support structure relative to the first support structure. In one embodiment, loading applied to the second support structure is distributed between the first pivot point and the second pivot point during operation of the surgical apparatus.
