A total of 72 cases of single-segment thoracolumbar fractures without neurologic injury underwent pedicle screw fixation via two different approaches. Among them, 37 patients were treated using posterior open surgery, and 35 patients received mini-open operation via Wiltse approach. Crew placement accuracy rate, operative time, blood loss, postoperative drainage, postoperative hospitalization time, radiation exposure time, postoperative improvement in R value, Cobb's angle and visual analog scale (VAS) scores of the two methods were compared. There were no significant differences in the accuracy rate of pedicle screw placement, radiation exposure and postoperative R value and Cobb's angle improvement between the two groups. However, the mini-open method had obvious advantages over the conventional open method in operative time, blood loss, postoperative drainage, postoperative hospitalization time, and postoperative improvement in VAS. The mini-open pedicle screw technique could be applied in treatment of single-segment thoracolumbar fracture without neurologic injury and had advantages of less tissue trauma, short operative and rehabilitative time on the premise of guaranteed accuracy rate and no increased radiation exposure.展开更多

Seventeen patients from 2007 to 2009 underwent anterior debridement and fusion with a minimally invasive approach combined with posterior fixation via the Wiltse approach. Postoperative follow-up time was 24-41 months. Data included the patients' general information, mi- crobiology, operative time, intraoperative blood loss, postoperative complications, intervertebral fusion rate, and preoperative and final follow-up scores for American Spinal Injury Association (ASIA) im- pairment, visual analogue scale (VAS), and Oswestry Disability Index (ODI). Ten patients had under- gone a prior spinal invasive procedure, and 7 had hematogenous infection. The infected segments in- cluded L1-2, L2-3, L3,~, and L4-5 in 1, 2, 5, and 9 cases, respectively. Thirteen bacterial cultures were posi- tive for Staphylococcus aureus (5 cases), Staphylococcus epidermidis (4), Streptococcus (3), and Es- cherichia coli (1). The operative time was 213.8+45.6 min, and the intraoperative blood loss was 180.6-4-88.1 mL. Postoperative complications consisted of urinary retention (2 cases), constipation (3), and deep vein thrombosis (2). On the final follow-up, VAS scores and ODIs were significantly lower than those of preoperation, while the ASIA grades improved. All the cases achieved good intervertebral bony fusion. Anterior debridement and fusion with a minimally invasive approach combined with poste- rior fixation via the Wiltse approach can successfully treat single-level lumbar pyogenic spondy- lodiscitis, with less trauma and reliable immobilization. It is a viable option for clinical application.展开更多
