Navigation Assisted Minimally Invasive Percutaneous Fixation For The Treatment Of Thoracic And Lumbar Spinal Fractures

Objective:To evaluate the clinical effect of minimally invasive navi gation assisted percutaneous fixation for the treatment of thoracolum bar fractures.Methods:From2011September to2013February,30cases of injury lev el above without neural impairment, none of the patients required dec ompression of pure thoracolumbar fractures, in which the traditional open operation in15cases,15cases of percutaneous minimally invasi ve operation, the operation incision, operation time, intraoperative bleeding volume, postoperative drainage volume, postoperative activit y time and the days of admission number and other aspects of comparis on. Were recorded before surgery,1days,1months after surgery, the final follow-up visual analogue score (Visual Analogue, Scale\/Score, VAS), degree of pain relief, quality of life score (activity of dail y living, ADL). Preoperative and postoperative day1, the last follow-up lesions vertebral height, measured the kyphotic Cobb angle.Results:Based on the preoperative, postoperative day1,1months aft er operation, the last follow-up VAS score, pain relief, there was si gnificant difference of ADL score, pain significantly reduced. Preope rative and postoperative day1, the last follow-up lesions vertebral height, kyphosis Cobb angle measurement results exist significant dif ference. Operation incision minimally invasive group was significantl y less than the open group (7.53±0.74) cm VS (12.20±1.52) cm, P<0.05; the amount of hemorrhage group was significantly less than the op en group (50.67±11.63)ml VS (102±32.78)ml, P<0.05; minimally in vasive group, postoperative drainage volume was smaller than the open group (0)ml VS (292.67±35.55)ml, P<0.05; the average of minimally invasive surgery group after activity time is significantly less tha n the open group (2.67±0.62)d VS (4.27±0.80)d, P<0.05; minimall y invasive group average admission day number is smaller than the ope n group (8.47±1.13)d VS (9.53±2.07)d, P>0.05; operation time of minimally invasive group less than open group (91±12.71)min VS (106.33±8.34)min, P<0.05. The number of days of admission of minimal ly invasive operation group and the open operation group had no signi ficant difference (P>0.05), and the operation incision length, bleedi ng volume, postoperative drainage volume, operation time, postoperati ve ambulation time had significant difference (P<0.05). The two group s had no iatrogenic nerve root injuries. The open group in2cases, w ound infection1weeks after operation, the anti-infection, dressing and cured after treatment,1cases occurred3months after the left1ower extremity deep vein thrombosis; minimally invasive group had no obvious complications.Conclusion:Adaptation of thoracic and lumbar fracture operation stri ctly control card, navigation assisted minimally invasive percutaneou s fixation is a better choice in the treatment of thoracolumbar fract ures. Can the greatest degree of shortening the operation time, intra operative minimize’operation process again on the vertebral injury, i mprove operation safety. Postoperative can quickly relieve pain, impr ove function.
