US Patent 11311302 Ankle replacement system and method

Surgical methods are presented for sizing and adjusting a spacer and trial relative to a joint so as to properly position a cutting guide for resection of a bone. The trial may be inserted into a resected space in a first bone, and the spacer may be inserted into one or more channels defined by the trial. The laxity of one or more ligaments may be assessed relative to at least one of the trial and the spacer.
