Clinical efficacy analysis on the treatment of thoracolumbar fractures via paraspinal muscle gap approach / 临床外科杂志

ABSTRACT

Objective To investigate the clinical efficacy of paraspinal muscle gap approach in the short segment internal fixation of thoracolumbar fractures.Methods Forty-five patients with thoraco-lumbar fractures but without spinal decompression underwent posterior short segment internal fixation,in-cluding 20 cases via paraspinal muscle gap approach(group A)and 25 cases via traditional posterior mid-line approach.Operative time,intraoperative blood loss,postoperative drainage,visual analogue scale (VAS)score,correction rate of Cobb angle and correction rate of vertebral collapse were recorded and the surgical results were compared between the groups.Results All patients got bony union without internal fixation loosening,broken nails or broken rods.There were significant differences in operative time [(88 ± 17)min vs(105 ±14)min],blood loss [(121 ±24)ml vs(230 ±31 )ml]and postoperative drainage [(66 ±28)ml vs(250 ±45)ml]between group A and B respectively(P0.05 ).Conclusion Internal fixation via paraspinal muscle gap approach has the advantages of less trauma,simple approach,short operative time,less blood loss,quick recovery after surgery.It is consistent with the modern concept of minimal invasion and worthy of sprea-ding.
