摘要

To compare the clinical effects and multifidus muscle injury of different approaches, including unilateral Wiltse intermuscular approach and intramuscular approach combined with contralateral decompression, in treating thoracolumbar burst fracture.Forty-three patients with thoracolumbar burst fracture were enrolled in the study from January 2010 to December 2014, including 29 males and 14 females with an average age of 42.3 years old(ranged from 21 to 64 years old). The patients were treated with posterior pedicle screw fixation and unilateral decompression and were divided into Wiltse intermuscular approach group (group A) and intramuscular approach group (group B) according to surgical approach. Operation time and intraoperative bleeding were recorded for all patients; visual analogue scale(VAS) was compared 1 d preoperatively, 1 week, 12 months postoperatively between two groups; preoperation and 12 months postoperatively, the fractured vertebral canal and two-sides multifidus muscle of the same section were observed and compared by CT measure between two groups.All the patients were follow-up for 14 to 21 months with an average of 16.3 months. Partial wound non-healing occurred in 3 patients and the wound ultimately healing after debridgement suture and change dressings. No screw breakage was found. There was significant difference in operation and intraoperative bleeding operation between two groups (P<0.05), while there was no significant difference in VAS score of 1 d preoperatively, 1 week, 12 months postoperatively between two groups(P>0.05). As for CT measurement results, postoperative vertebral canal narrow ratio was significant decreased in all patients(P<0.05), while perioperative changes of the two-sides multifidus muscle cross section area and density were significant in group A (P<0.05), but there was no significant difference in group B (P>0.05). Neurologic status of all patients got recovery at final follow-up.The method of unilateral Wiltse intermuscular approach combined with contralateral decompression for the treatment of thoracolumbar burst fracture has good clinical effects, also it is less invasive and less damage to multifidus muscle compared with intramuscular approach.
