[Study on the effect of vertebrae semi-dislocation on the stress distribution in facet joint and interuertebral disc of patients with cervical syndrome based on the three dimensional finite element model]

OBJECTIVE: To study the effect of vertebrae semi-dislocation on the stress distribution in facet joint and interuertebral disc of patients with cervical syndrome using three dimensional finite element model. METHODS: A patient with cervical spondylosis was randomly chosen, who was male, 28 years old, and diagnosed as cervical vertebra semidislocation by dynamic and static palpation and X-ray, and scanned from C(1) to C(7) by 0.75 mm slice thickness of CT. Based on the CT data, the software was used to construct the three dimensional finite element model of cervical vertebra semidislocation (C(4)-C(6)). Based on the model,virtual manipulation was used to correct the vertebra semidislocation by the software, and the stress distribution was analyzed. RESULTS: The result of finite element analysis showed that the stress distribution of C(5-6) facet joint and intervertebral disc changed after virtual manipulation. CONCLUSION: The vertebra semidislocation leads to the abnormal stress distribution of facet joint and intervertebral disc

This surgical technique consists of a percutaneous approach for the treatment of small to medium size hernias of the intervertebral disc by laser energy. The main objective is to reduce the intradiscal pressure in the nucleus pulposus

Laser Disc Surgery can be performed under local anaesthetic as a day case at our centre on the prestigious Harley Street.
