Abstract：Objective To explore the values of the improved Load-Sharing scoring system for the choice of surgical meth-odin the treatment of thoracolumbar spine fracture.Methods The 69 thoracolumbar spine fracture patients from September 2010 to January 2014 in our hospital were selected and accepted different surgery approach according to modified Load-sharing score. Posterior surgery was suitable for 4~6 scores. Anterior surgery+subtotal vertebrectomy + anterior bone graft was suit-able for≥7 scores without vertebral rear structural damage or dislocation. Anterior combined posterior surgery + subtotal verte-brectomy + anterior bone graft were suitable for≥7 scores with vertebral rear structural damage or dislocation. Clinical results were recorded.Results Cobb angle,spinal canal and vertebral compression in all patients were restored after surgery.The difference between pre-and post-surgery was statistically significant(P<0. 05). There were 40 patients of incomplete neurolog-ical impairment in which 2 cases of neurological recovery by 3,14 cases of neurological recovery by 2 and 24 cases of neurolog-ical recovery by 1. The evaluation of low back pain according to Denis classification were 49 cases of P1,14 cases of P2 and 6 cases of P3. 31 cases backed to the original work or physical labor. 32 cases had light work. 6 cases lived without aid but could not participate innormal work and labor.Conclusion The improved Load-Sharing scoring system has important guiding value for the choice of surgical method in the treatment of thoracolumbar spine fracture.
