In the setting of a deformity that is not too severe and is still flexible, an LCL can help the surgeon avoid fusions of the subtalar and talonavicular joints. Radiographically, the abduction should be corrected so that there is a normal amount of uncoverage of the talar head (30% or less), and no adduction of the talonavicular joint. These findings demonstrate the need for clinical investigation of this procedure, which could preserve motion in the talonavicular and subtalar joints, correct deformity, and obviate calcaneocuboid arthritis. official website and that any information you provide is encrypted Inversion/eversion motion was produced by tendon pulls and the range of motion was measured in three dimensions using a magnetic space tracker.
