ABSTRACT
Objective To investigate the clinical efficacy of short segment fixation with percutaneous pedicle screws or traditional open surgery for the type A1-A3 thoracolumbar compression fracture.Methods A retrospective case control study was conducted on the clinical data of 64 patients with thoracolumbar compression fracture admitted to Shanxi Dayi Hospital between January 2012 and February 2017.There were 44 males and 20 females,aged 21-65 years [(45.4 ± 11.1) years].There was one patient with injured segment at T11,29 at T12,27 at L1 and seven at L2.According to AO typing,there were 39 patients classified as Type A1,two as Type A2 and 23 as Type A3.The patients were divided into minimally invasive surgery group (n =37) and open surgery group (n =27).Minimally invasive surgery group was treated with minimally invasive percutaneous pedicle screw fixation and open reduction.The open surgery group was treated with traditional open pedicle screw short segment fixation and open reduction.The operation time,intraoperative blood loss,total hospitalization time,postoperative hospitalization time,visual analogue scale (VAS) before and after operation,local kyphosis of the fractured vertebra,segmental kyphosis and complications in two groups were recorded.Results All patients were followed up for 12-29 months,with an average of 13.2 months.Between the minimally invasive surgery group and open surgery group,no significant difference was found in the operation time [(106.4± 37.3) minutes vs.(131.3 ± 33.6) minutes] (P ＞ 0.05),and significant differences were found in intraoperative blood loss [(71.2 ± 34.9) ml vs.(409.3 ± 267.5) ml],total hospitalization time [(11.7 ± 7.2) days vs.(21.6 ± 12.8) days] and postoperative hospitalization time [(8.1 ± 7.4) days vs.(16.6 ± 10.6) days] (P ＜ 0.05).In the minimally invasive surgery group,VAS was (6.5 ±1.1) points preoperatively and was (2.3 ± 0.7) points and (1.0 ± 0.3) points immediately after operation and at final follow-up.In the open surgery group,VAS was (6.9 ± 1.0)points preoperatively and was (4.2 ± 1.0) points and (0.9 ± 0.4) points immediately after operation and at final follow-up (P ＜0.05).Compared with the preoperative VAS,those immediately after operation and at final follow-up were significantly decreased within the two groups (P ＜ 0.05).There were no significant differences in the preoperative VAS and VAS at final follow-up between the two groups (P ＞ 0.05),but significant difference was found in VAS immediately after operation between the two groups (P ＜ 0.05).In the minimally invasive surgery group,the local kyphosis of the fractured vertebra was (19.3 ± 3.8) °preoperatively,(3.4 ± 1.7) ° immediately after operation,and (4.6 ± 1.9) ° at final follow-up.In the open surgery group,the local kyphosis of the fractured vertebra was (19.6 ± 6.8) ° before operation,(1.6 ± 0.8) ° immediately after operation,and (2.4 ± 1.1) ° at final follow-up.The kyphosis of fractured vertebra immediately after operation and at final follow-up were significantly decreased within the two groups compared with the preoperative kyphosis(P ＜0.05),but no significant differences were found between the two groups (P ＞ 0.05).In the minimally invasive surgery group,the segmental kyphosis Cobb angle was (16.1 ± 9.1) ° before operation,(3.0-± 1.8) ° immediately after operation,and (5.9 ±1.8) ° at final follow-up.In the open surgery group,the segmental kyphosis Cobb angle was (15.2±12.0) ° before operation,(3.1 ± 1.4) ° immediately after operation,and (5.6 ± 2.1) ° at final follow-up.The segmental kyphosis Cobb angle immediately after operation and at final follow-up were significantly decreased within the two groups compared with the preoperative Cobb angle (P ＜ 0.05),but no significant differences were found between the two groups (P ＞ 0.05).No spinal cord injuries because of pedicle screws were observed after operation in either group.In the open surgery group,there was one patient with wound infection who recovered after dressing change,and no infection case was found in the minimally invasive surgery group.Conclusion For type A1-A3 thoracolumbar compression fractures,both the minimally invasive posterior pedicle screw fixation and the traditional open pedicle screw fixation can achieve satisfactory near-term results,and the former is better in intraoperative blood loss,immediate relief of pain after operation and shorter hospital stay than the latter.
ABSTRACT
[ABSTRACT]OBJECTIVETo assess the clinical effects of proton pump inhibitor(PPI) combined with traditional Chinese medicine for laryngopharyngeal reflux disease(LPRD).METHODSA total of 74 LPRD patients with laryngopharyngeal signs and symptoms confirmed by reflux symptom index(RSI) and reflux finding score(RFS) were enrolled. All patients received PPI combined with traditional Chinese medicine therapy. Effect evaluation was conducted at 2, 6, 12, and 18 months after the beginning of therapy.RESULTSThe relief rate was 74.3%, 90.5%, 87.8%, and 86.5% at the 2, 6, 12, and 18 months after the beginning of treatment respectively.CONCLUSIONPPI combined with traditional Chinese medicine therapy is safe and effective for LPRD and worthy of wide application.
