The Exploration Of Thoracolumbar Burst Fracture Vertebral Posterior Border Bone Mass Size And The Need For Surgical Treatment

Objective: To investigate the thoracolumbar burst fracture vertebral posterior border bone mass size and the need for surgical treatment , in order to provide reference for further clinical applications.Methods: A follow-up from July 2003 to July 2010 about to 63 patients in Shandong University of Traditional Chinese Medicine Second Affiliated Hospital (formerly the Railway Hospital) inpatient orthopedic surgery of thoracolumbar burst fracture . Routine spinal canal exploration, according to vertebral posterior border bone mass size is divided into two groups need to be addressed. A group which do not need devices to reset or removal and fracture reduction on their own,includes 31 patients (19 males, 12 females) aged from 15 to 68 years ; B group required assisted surgical reduction or removal fracture fragment with instruments to reset stability totals 32 patients (21 males and 11 females) which aged frome 12 to 63 years. A, B groups according to preoperative CT in patients with vertebral bone in the spinal canal occupational≤1/3 or >1/3, further divided into A1 (occupying≤1/3) 27 cases, A2 group (occupying> 1 / 3) in 4 cases, B1 group (occupying≤1/3) 3 cases, B2 group (occupying> 1 / 3) in 29 cases.A1 and A2 groups are compared while B1 and B2 groups are compared respectively in order to proved vertebral bone occupying 1 / 3 can be used as the need for bone surgery of reference int treatment from different angles.Statistics SPSS17.0 software for processing major applications. Choose t test and X2 test as treatment.Results: The retrospective study found that preoperative imaging data show that vertebral burst fracture vertebral bone in the spinal space occupying less than 1/3 of patients do not need to reset or removal of equipment, intraoperative vertebral distraction After relying on the soft tissue of the posterior longitudinal ligament and annulus of the traction splint the role of the role of bone are mostly free to reset the shift (A1 group, A2 comparison group of patients, a statistically significant difference); vertebral burst fracture vertebral bone block in the spinal space occupying more than 1/3 of the patients in the surgery of vertebral bone most need to address (B1 group, B2 comparison group of patients, a statistically significant difference).A group and B group were followed up by 5 to 15 months, mean 12.3±1.5 months. Spinal cord injury by Frankel grade, VAS pain score, ODI index were observed in the superior efficacy of preoperative patients.Conclusion:The thoracolumbar burst fracture vertebral posterior border bone in the spinal space occupying less than 1/3 of patients do not need to reset or removal with equipment, because of the majority can reset their own; if more than 1/3, the general need to deal with bone fragments.
