Former studies investigated only the intradiscal pressure after laser nucleotomy. As the outer anulus causes compression of neural structures, the present in vitro study was performed to investigate the circumferential pressure conditions of the outer posterolateral anulus following laser nucleotomy. STUDY DESIGN, MATERIALS AND METHODS: Laser nucleotomy was performed using a Hol:YAG laser (14 Watt, total energy applied 10kJ). Stiffness of the intervertebral disc and deviation of the posteriolateral portion of the disc under axial pressure were investigated. The forces observed during external deformation of the anulus were measured by stain gauges and recorded by a data logger. Measurements were taken at 4.8 and 10 kJ. The maximum axial load was 400 Newton.
