Abstract: ADR has been shown to be a viable option for the treatment of painful degenerative lumbar degenerative disc disease. However, studies have also shown conflicting effects of ADR. It is thus hypothesized that posteriorly-positioned ADR will restore the intact mechanics of the spinal joints at both the index (L4L5) and adjacent level (L3L4). 6 cadaveric lumbar spines (L2-S1) were mounted onto MTS 858 Spine Tester with a follower preload system of 280 N, pressure sensors inserted into the facet joints and their motion captured using Vicon cameras. Overall, posterior ADR at L4L5 resulted in the closest facet joint rotation and pressure compared to the intact spine model. However, an inverse effect between the implanted and the adjacent level parameters could be implied. Compensatory motion mechanism was observed which could imply the readjustment of the facet joints mechanics after ADR relative to the intact model.
