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

Methods: The prospective study included 68 patients (16 men and 52 women) aged 43 to 80 years (mean age: 64 years). Patients were evaluated in pre- and post-operative by a questionnaire. The mini open technique with cutaneous approach to the heel of the hand following the 4th ray was performed in all patients under local, locoregional or general anesthesia. Results: The results were evaluated in 3 consultations, in the 1st, 3rd and 6th month. We obtained very good results in 54.4% of the cases (n = 37) and 30.9% (n = 21) of good results and 14.70% (n = 10) of poor results. No vascular, tendinous or neurological complications were noted. Two patients were reoperated for incomplete resection of the carpal ring ligament. The mini-open technique has achieved good results in all neurolysis despite the delay in surgical management. Conclusion: The results of the surgical treatment of the carpal tunnel syndrome depend on the precocity of the diagnosis and the surgical indication.展开更多
