The method developed and used by the authors to measure intradiscal pressure is presented. We constructed 'needle* indicators lilted with miniature pressure transducers. Our analysis assessed the impact of stabilisation on pressure in intervcrtcbral discs adjacent to the stabilisation area under compression and bending loads. The research was carried out on the post-mortem specimens of the cervical spine. The results showed that during axial compression there is a small increase in pressure following the introduction of bone graft when compared to the intact spine. On the other hand, bending has a major influence on the resultant pressure, depending on spinal level and the type of bending (flexion/extension). We have also concluded that, regardless of the type of load, in the discs above (the planned and then implemented) stabilisation area, the pressure is lower than in discs located below.
