Objective To explore the clinical characteristics of the floating injury of symphysis pubis and clinical outcome of open reduction and internal fixation.Methods A retrospective study was conducted to analyze the 48 patients who had been treated in our department with open reduction and internal fixation for the floating injury of Symphysis pubis from January 2008 to January 2013.There were 31 males and 17 females,with an average age of 36.5 years (range,20 to 61 years).Thirty-five patients were injured in traffic accidents and 8 were injured by falling injuries,and the other 5 were crushed by maehine.Fortyfive cases were complicated with fractures of the posterior pelvis ring; 14 cases were complicated with acetabular fractures; 17 cases were complicated with extremity fractures; 1 1 cases were complicated with thoracic and abdominal injuries and 6 cases were associated with urogenital system injury.The average period from trauma to operation was 7 days (range,3 to 25 days).Operation was performed under general anesthesia.The bilateral pubic ramus fractures were fixed with reconstruction plate in 41 cases,and 7 cases were fixed with cannulated screw through minimally invasive method.Forty-one cases with posterior ring fractures were fixed simulaneously.Results There were 44 patients being followed up with an average period of 16 months (range,12 to 30 months).All the fractures of the pelvis were clinically healed with an average period of 12.6 weeks (range,10 to 16 weeks).According 图o the Majeed score system,the functional results were exc ellent in 30 cases,good in 10 cases,and fair in 4 cases; The average score was 81.5 (range,60 to 100).Two patients who had wound fat liquefaction at 3 days after operation were healed by dressing changing; 8 patients got deep vein thrombosis at 10 days (range,5 to 15 days) after operation were cured by conservative treatment; 3 patients got supra pubic pain at 6 days (range,5 to 7 days) after operation were healed by oral non steroidal anti-inflammatory analgesic drugs and physical therapy in one year.Conclusion Floating injury of symphysis pubis is a kind of severe pelvic fracture which affects the stability of pelvic ring.Open reduction and internal fixation is a good method to stabilize the pelvis ring and to get early rehabilitation.This may contribute to good clinical resuls and good function.

Sugarcane bagasse modified by polyethylenimine (PEI) and glutaraldehyde (GA) was used as a carrier to immobilize Clostridium acetobutylicum XY16 in the process of butanol production. The effects of chemically modified sugarcane bagasse on batch and repeat-batch fermentations were investigated. Batch fermentation was conducted with an addition of 10 g/L modified sugarcane bagasse and 60 g/L glucose, resulting in a high solvent concentration of 21.67 g/L and productivity of 0.60 g/(L x h) with the treatment of 4 g/L PEI and 1 g/L GA. Compared to the fermentations by free cells and immobilized cells on unmodified sugarcane bagasse, the productivity increased 130.8% and 66.7%, respectively. The fibrous-bed bioreactor also maintained a stable butanol production during repeat-batch fermentations, achieving a maximum productivity of 0.83 g/(L x h) with a high yield of 0.42 g/g.

Objective:To compare the clinical efficacy of percutaneous vertebroplasty (PVP) and non-surgical treatment of patients with type I fracture according to the acute symptomatic osteoporotic thoracolumbar fracture (ASOTLF) classification.Methods:A retrospective case-control study was used to analyze the clinical data of 115 patients with ASOTLF admitted to Honghui Hospital of Xi'an Jiaotong University from January 2015 to December 2018. There were 48 males and 67 females, aged 65-92 years [(75.3±8.5)years]. According to clinical symptoms and imaging characteristics, all patients were identified with type I fracture according to the ASOTLF classification. Injury segments were at T 6 to T 10 in 10 patients, at T 11 in 15, at T 12 in 26, at L 1 in 34, ay L 2 in 18, at L 3 in 7, and at L 4 in 5. A total of 73 patients received PVP combined with anti-osteoporosis treatment (surgery group), and 42 patients received non-surgery combined anti-osteoporosis treatment (non-surgery group). Before treatment, at 1 day, 1 month, 3 months, 6 months after treatment, and at the last follow-up, the visual analogue scale (VAS) was used to assess the pain, the Roland Morris Disability (RMD) score to assess the spinal function, and the Quality of Life Questionnaire of the European Foundation for Osteoporosis (QUALEFFO) score to evaluate the quality of life. The bone mineral density was compared between groups before treatment and at 1 year after treatment. The complications were observed as well. Results:All patients were followed up for 12-18 months [(13.2±4.6)months]. At 1 day, 1 month, and 3 months after treatment, the VAS in surgery group [(3.9±0.6)points, (3.3±0.6)points, (2.9±0.3)points] was significantly lower than that in non-surgery group [(6.0±0.7)points, (5.0±0.8)points, (4.2±1.0)points, respectively] (all P<0.05); the RMD score in surgery group [(15.2±0.7)points, (12.6±0.7)points, (10.6±0.7)points] was significantly lower than that in non-surgery group [(16.4±0.8)points, (14.6±0.8)points, (12.7±0.6)points, respectively] (all P<0.05). At 1 day and 1 month after treatment, the QUALEFFO score in surgery group [(46.0±1.1)points, (41.4±0.8)points] was lower than that in non-surgery group [(50.3±0.8)points, (44.7±1.2)points] (all P<0.05). There was no statistically significant difference between the two groups at other time points of the above indicators ( P>0.05). At 1 year after treatment, the bone mineral density in surgery group was (-3.0±0.9)SD, and was (-2.8±1.1)SD in non-surgery group ( P>0.05). There was no significant difference in the incidence of complications between surgery group [37%(27/73)] and non-surgery group [33%(14/42)] ( P>0.05). Conclusion:For patients with ASOTLF type I fracture, PVP and non-surgical treatment has similar effects in anti-osteoporosis and occurrence of complications, but the PVP is superior to non-surgical treatment in early pain relief, spinal function improvement and quality of life.

Objective:To explore the treatment options for patients with osteoporotic thoracolumbar injury classification and severity score (OTLICS) of 4 points following acute symptomatic osteoporotic vertebral compression fracture (OVCF) .Methods:A retrospective case-control study was conducted to analyze the clinical data of 108 patients with acute symptomatic OVCF admitted to Honghui Hospital, Xi'an Jiaotong University Faculty of Medicine from February 2016 to February 2018. There were 21 males and 87 females, aged 55-92 years [(71.6±5.3)years]. All patients had OTLICS score of 4 points. Of all, 76 patients were treated operatively (surgery group) and 32 patients were treated non-operatively (non-surgery group). The visual analogue scale (VAS), Oswestry disability index (ODI) and quality of life score (SF-36) were compared between the two groups before treatment, at 1 week, 3 months, 6 months after treatment, and at the last follow-up. The recovery of the injured vertebrae before and after treatment (Cobb angle of the injured vertebra, relative height of the anterior edge of the injured vertebrae), adjacent vertebral body fractures, and complications were compared between the two groups.Results:All patients were followed up for 12-18 months [(13.4±4.2)months]. At 1 week, 3 months and 6 months after treatment, the VAS in surgery group [(3.5±1.0)points, (2.1±0.6)points, (2.0±0.4)points] was better than that in non-surgery group [(6.4±1.7)points, (5.3±1.5)points, (3.3±0.6)points] ( P<0.05), the ODI in surgery group [(45.8±10.3)points, (35.3±8.6)points, (26.5±7.1)points] was better than that in non-surgery group [(65.7±12.1)points, (58.3±10.7)points, (45.6±9.3)points] ( P<0.05), the SF-36 in surgery group [(82.8±1.4)points, (85.0±1.5)points, (88.0±1.3)points] was better than that in non-surgery group [(80.4±1.3)points, (81.5±1.4)points, (85.6±1.1)points] ( P<0.05). At the last follow-up, there were no significant differences in VAS, ODI and SF-36 between the two groups ( P>0.05). At 3 months, 6 months and the last follow-up, the Cobb angle in surgery group [(18.3±3.9)°, (17.5±3.0)°, (17.8±1.6)°] was better than that in non-surgery group [(22.4±2.2)°, (22.5±1.7)°, (22.1±1.3)°] ( P<0.05), and the relative height of the anterior edge of the injured vertebra in surgery group [(75.4±8.6)%, (76.6±8.6)%, (75.2±8.3)%] was better than that in non-surgery group [(63.5±7.6)%, (65.2±7.4)%, (62.8±7.2)%] ( P<0.05). The adjacent vertebral fractures occurred in 6 patients (8%) in surgery group, and in 2 patients (6%)in non-surgey group ( P>0.05). Postoperative complications occurred in 8 patients (11%) in surgery group, and occurred in 6 patients (19%) in non-surgery group ( P>0.05). Conclusion:When applying the OTLICS scoring system to treat acute symptomatic OVCF, patients with OTLICS score of 4 points should be promptly treated with operatively, which can quick relieve pain, correct deformities promote functional recovery, and improve quality of life.

Objective:To test and evaluate the reliability and clinical effectiveness of osteoporotic thoracolumbar fracture (OTLF) scoring and classification system.Methods:A multicenter retrospective case series study was conducted to analyze the clinical data of 530 OTLF patients admitted to 8 hospitals including Honghui Hospital Affiliated to Xi'an Jiaotong University from January 2021 to June 2022. There were 212 males and 318 females, aged 55-90 years [(72.6±10.8)years]. There were 4 patients with grade C and 18 with grade D according to American Spinal Injury Association (ASIA) classification. According to the osteoporotic thoracolumbar injury classification and severity (OTLICS) score, all patients had an OTLICS score over 4 points and required surgical treatment. Among them, 410 patients had acute symptomatic OTLF (ASOTLF), including 24 patients with type I, 159 type IIA, 47 type IIB, 31 type IIC, 136 type IIIA, 8 type IIIB, 2 type IV (absence of neurological symptoms) and 3 type IV (presence of neurological symptoms), and 120 patients had chronic symptomatic OTLF (CSOTLF), including 62 patients with type I, 21 type II, 17 type III, 3 type IV (reducible under general anesthesia), 9 type IV (not reducible under general anesthesia), 1 type V (reducible under general anesthesia), 5 type V (presence of neurological symptoms), and 2 type V (not reducible under general anesthesia). Surgical procedures included percutaneous vertebroplasty (PVP), positional repositioning plus PVP, percutaneous kyphoplasty (PKP), posterior open reduction combined with bone graft fusion and bone cement augmented screw internal fixation, posterior open reduction combined with decompression, bone graft fusion and bone cement augmented screw internal fixation, and posterior open reduction combined with osteotomy and orthopedics, bone graft fusion and bone cement augmented screw internal fixation. A weighted Kappa was used to test the interobserver and intraobserver reliability of the OTLICS score, the ASOTLF classification, and the CSOTLF classification. The visual analog scale (VAS), Oswestry disability index (ODI), ASIA classification were compared before, at 1 month after surgery and at the last follow-up. Incidence of postoperative complications was observed.Results:The percentage of mean interobserver agreement for OTLICS staging was 93.4%, with a mean confidence Kappa value of 0.86, and the percentage of mean intraobserver agreement was 93.0%, with a mean confidence kappa value of 0.86. The percentage of mean interobserver agreement for ASOTLF staging was 94.2%, with a mean confidence Kappa value of 0.84, and the percentage of mean intraobserver agreement was 92.5%, with a mean confidence Kappa value of 0.83. The percentage of mean interobserver agreement for CSOTLF subtyping was 91.9%, with a mean confidence Kappa value of 0.80, and the percentage of mean intraobserver agreement was 91.3%, with a mean confidence Kappa value of 0.81. All the patients were followed up for 6-12 months [(9.0±2.1)months]. The VAS and ODI scores were significantly lower in patients with ASOTLF and CSOTLF classifications at 1 month after surgery and at the last follow-up than those before surgery (all P<0.05). The VAS scores in patients with ASOTLF types IIA, IIB, IIC, IIIA, and IV were significantly lower at the last follow-up than that at 1 month after surgery; the ODI scores in patients with ASOTLF types I, IIA, IIB, IIIA, IIIB and IV were significantly lower at the last follow-up than those at 1 month after surgery. The VAS scores in patients with CSOTLF types II, III, IV, and V were significantly lower at the last follow-up than those at 1 month after surgery, and the ODI scores in patients with all CSOTLF types were significantly lower at the last follow-up than those at 1 month after surgery (all P<0.05). Two patients with ASIA grade C recovered to grade D, and the rest recovered to grade E at the last follow-up ( P<0.01). No major vessel or nerve injury or internal fixation failure was found during follow-up. There were 18 patients with cement leakage, none of whom showed relevant clinical symptoms. There were 35 patients with new vertebral fractures, all of whom recovered well after symptomatic treatment. Conclusions:The OTLICS score, ASOTLF classification and CSOTLF classification have a high degree of reliability. Application of stepwise treatment for patients with different levels of injury according to the scoring and classification system can reduce pain, promote recovery of the spinal function, and reduce complications, which is of some significance in guiding the selection of clinical treatment.
