Immediate Biomechanical Effects of Lumbar Posterior Dynamic Stabilisation
The current premise, on which spinal fusion is offered to patients with a painful lumbar motion segment, is that the pain arises secondary to abnormal motion or “instability”. By the elimination of this motion, one hopes to eliminate the pain. However, results following spinal fusion are far from predictable, with reported satisfactory clinical results ranging from 46 to 82% [1, 2]. Furthermore, many patients complain of postural or positional pain occurring without motion, suggesting that low back pain may have aetiologies relating to abnormal load transmission rather than abnormal kinematics.
