Abstract: Instruments and related methods for breaking reduction tabs are disclosed herein, e.g., for breaking reduction tabs of a bone anchor or other implant. In some embodiments, the instrument can be configured to minimize the space needed to operate the instrument. For example, the instrument can be configured to receive a reduction tab that is to be broken while the instrument is coaxially positioned with respect to a bone anchor receiver to which the reduction tab is attached. As another example, the instrument can have a maximum outer transverse dimension that is less than, equal to, or only slightly greater than a corresponding dimension of a bone anchor from which a reduction tab is to be broken. Guide rods for positioning a tab breaker instrument over a reduction tab are also disclosed.

Abstract: Disclosed is an instrument for balancing a knee. The instrument has a first plate (10) coupled to a second plate (50) by a plurality of adjusters (152A, 152B, 152C). The adjusters are actuatable to vary the gap between the first and second plates. Each adjuster is coupled to the second plate by a joint having at least two degrees of freedom. Also disclosed is an outrigger (300). The outrigger includes a body featuring a connection component configured to be received and held by a slot (34) of the instrument. The slot is arranged to align a blade of a surgical saw with a portion of a knee to be cut. Also disclosed is a method of balancing a knee using the instrument and a method of fabricating the instrument.
