ABSTRACT

Diffuse idiopathic skeletal hyperostosis(DISH) is a kind of ankylosing spinal disease, which usually occurs in the middle-aged and elderly. It is mainly manifested as ossification and calcification of ligaments and tendon attachment points. It is a bone disease that mainly involves the spine but is not accompanied by severe intervertebral disc degeneration or sacroiliac joint and intervertebral facet joint ankylosis. DISH combined with thoracolumbar fracture has a high rate of delayed diagnosis and neurological deterioration, so this kind of fracture should be diagnosed and treated in time. However, there are different conclusions on the choice of treatment methods and postoperative efficacy, and there are still disputes in some academic aspects.The author consulted the relevant literature and reviewed the treatment methods of DISH combined with thoracolumbar fracture in order to provide reference for the clinical treatment of this kind of fracture.

ABSTRACT

Objective:To investigate the risk factors associated with the occurrence of proximal junctional kyphosis (PJK) after posterior long-segment internal fixation for type IV chronic symptomatic osteoporotic thoracolumbar fracture (CSOTLF) in the elderly.Methods:A case-control study was used to analyze the clinical data of 95 elderly patients with type IV CSOTLF treated in Honghui Hospital affiliated to Xi′an Jiaotong University from January 2013 to June 2018, including 32 males and 63 females, aged from 60 to 85 years[(67.4±6.5) years]. Injured segments were T 11 in 17 patients, T 12 in 37, L 1 in 30 and L 2 in 11. All patients were treated with posterior long-segment internal fixation and divided into PJK group ( n=30) and non-PJK group ( n=65) according to whether PJK occurred after surgery. Univariate analysis was performed for the correlation of the following indices with the incidence of postoperative PJK, including general information such as gender, age, body mass index (BMI), bone mineral density (BMD), history of smoking, cause of injury, comorbidities, injury segments, American Spinal Injury Association (ASIA) classification and time from injury to surgery, preoperative imaging data such as posterior junctional angle (PJA), sagittal vertical axis (SVA), pelvic incidence-lumbar lordosis difference (PI-LL), pelvic tilt (PT) and sacral slope (SS), basic surgical data such as posterior ligament complex (PLC) injury, location of upper instrumented vertebrae (UIV), location of lower instrumented vertebrae (LIV) and number of fixed segments. Multifactorial Logistic regression analysis was used to measure the independent risk factors associated with the occurrence of postoperative PJK. Results:Univariate analysis showed that the incidence of postoperative PJK was correlated with age, BMI, BMD, preoperative PJA, preoperative SVA, preoperative PI-LL, PLC injury, location of UIV, location of LIV and number of fixed segments (all P<0.05), rather than gender, history of smoking, cause of injury, comorbidities, injury segments, ASIA classification, time from injury to surgery, preoperative PT and preoperative SS (all P>0.05). Multifactorial Logistic regression analysis showed that age ≥70 years ( OR=32.28, 95% CI 3.83-272.29, P<0.01), BMI>28.0 kg/m 2 ( OR=7.88, 95% CI 1.63-37.99, P<0.01), BMD T value<-3.5 SD ( OR=20.84, 95% CI 2.36-183.93, P<0.01), preoperative PI-LL>20° ( OR=13.30, 95% CI 1.54-113.87, P<0.05) and PLC injury ( OR=13.98, 95% CI 1.37-142.34, P<0.05) were significantly associated with the occurrence of postoperative PJK. Conclusions:Age≥70 years, BMI>28 kg/m 2, BMD T value<-3.5 SD, preoperative PI-LL>20° and PLC injury are independent risk factors for the incidence of PJK after posterior long-segment internal fixation in elderly patients with type IV CSOTLF. Attention should be paid to soft tissue protection and sagittal balance restoration of the spine intraoperatively and weight control and anti-osteoporosis treatment postoperatively.

ABSTRACT

Objective:To explore the clinical effects of unilateral secondary puncture percutaneous vertebroplasty (PVP) in the treatment of type ⅡA acute symptomatic osteoporotic thoracolumbar fractures (ASOTLF).Methods:A retrospective case-control study was conducted to analyze the clinical data of 193 patients with type ⅡA ASOTLF who had been admitted to Department of Spine Surgery, Honghui Hospital from February 2016 to October 2018. They were 71 males and 122 females, aged from 65 to 90 years [average, (73.9±4.3) years]. The segments injured were T10 in 21 cases, T11 in 27 cases, T12 in 44 cases, L1 in 48 cases, L2 in 29 cases, L3 in 14 cases, and L4 in 10 cases. Of them, 85 received unilateral secondary puncture PVP (observation group) and 108 did not (control group). The clinical effects were evaluated by comparing between the 2 groups the operation time, bone cement injection volume, intraoperative blood loss, hospital stay, and visual analogue scale (VAS) for back pain, spinal Oswestry disability index (ODI), anterior height of the injured vertebral body (AH) and kyphosis angle (KA) of the injured vertebra before operation, at 3 days after operation and the last follow-up. The bone cement leakage and fracture of adjacent vertebral body were observed.Results:All patients were followed up for 12 to 24 months (average, 15.8 months). There was no significant difference in the preoperative general data between the 2 groups, showing they were comparable ( P>0.05). The operation time and bone cement injection volume [(36.2±1.4) min and (5.5±0.7) mL] in the observation group were significantly longer or more than those in the control group [(32.3±1.7) min and (4.0±0.7) mL] ( P<0.05). There was no significant difference in the hospital stay or intraoperative blood loss between the 2 groups ( P>0.05). The VAS, ODI, AH and KA at 3 days after operation and the last follow-up were significantly improved compared with those before operation in both groups ( P<0.05). There was no significant difference in VAS, ODI, AH or KA between the 2 groups before operation or at 3 days after operation ( P>0.05). However, the VAS, ODI, AH and KA at the last follow-up in the observation group [(2.2±0.8) points, 19.2%±5.8%, (2.90±0.21) cm, and 12.2°±1.5°] were better than those in the control group [(3.1±0.9) points, 22.8%±5.3%, (2.41±0.15) cm, and 13.3°±1.2°]. There was no significant difference between the 2 groups in the incidence of postoperative bone cement leakage or that of adjacent vertebral fracture ( P>0.05). Conclusions:In the treatment of type ⅡA ASOTLF, unilateral secondary puncture PVP can result in satisfactory clinical effects, because it effectively promotes dispersion of bone cement and prevents re-collapse of the vertebra operated but does not increase the risks of bone cement leakage and adjacent vertebral fracture.

ABSTRACT

Objective:To investigate the efficacy of flexion-lateral curvature-supination reduction combined with primary anterior surgery for the treatment of lower cervical dislocation with unilateral facet inter-locking.Methods:A retrospective analysis was performed in the 32 patients who had been admitted to Department of Spine Surgery, Honghui Hospital for lower cervical dislocation with unilateral facet interlocking from November 2015 to October 2018. According to their treatments, they were divided into 2 groups. In the emergency group treated by flexion-lateral curvature-supination reduction combined with primary anterior surgery, there were 13 males and 3 females, aged from 24 to 63 years. In the traction group treated by cranial traction reduction combined with secondary anterior surgery, there were 12 males and 4 females, aged from 20 to 64 years. The operation time, intraoperative blood loss, hospital stay, bone graft fusion, American Spinal Injury Association (ASIA) grade and Japanese Orthopaedic Association (JOA) score were compared between the 2 groups.Results:There was no significant difference in the preoperative general data between the 2 groups, showing they were comparable ( P<0.05). All patients were followed up from 26 to 40 months. The hospital stay for the emergency group [(7.2±1.2) d] was significantly shorter than that for the traction group[(10.9±1.2) d] ( P<0.05). There was no significant difference in the operation time, blood loss, ASIA grade or JOA score between the 2 groups ( P>0.05). All patients achieved osseous fusion of intervertebral space. Conclusion:Compared with traditional methods, flexion-lateral curvature-supination reduction combined with primay anterior surgery shows no significant difference in the recovery of neurological function but leads to a shorter hospital stay.

ABSTRACT

Objective:To compare the efficacy of forceful reduction percutaneous pedicle screw and ordinary percutaneous pedicle screw in the treatment of osteoporotic thoracolumbar burst fracture with kyphosis.Methods:A retrospective cohort study was conducted to analyze the clinical data of 566 patients with osteoporotic thoracolumbar burst fracture with kyphosis admitted to Honghui Hospital, Xi ′an Jiaotong University from January 2015 to December 2018, including 191 males and 375 females, with age range of 48-79 years [(61.7±10.7)years]. Fracture segments were located at T 11 in 134 patients, T 12 in 154, L 1 in 160, and L 2 in 118. All fractures were type IIIA according to the acute symptomatic osteoporotic thoracolumbar fracture classification (ASOTLF). The thoracolumbar osteoporotic fracture severity score assessment system (TLOFSAS) score was ≥5 points. A total of 275 patients underwent forceful reduction and percutaneous pedicle screw internal fixation (forceful reduction screw group), and 291 patients underwent common percutaneous pedicle screw internal fixation (common screw group). The operation time, intraoperative blood loss, times of X-ray exposure on patients and measures documented before operation, at 3 days after operation and at 2 years after operation including anterior height ratio of the injured vertebrae, sagittal Cobb angle of the injured vertebrae, Japanese Orthopaedic Association (JOA) score and visual analog scale (VAS) were compared between the two groups. Moreover, degree of correction of Cobb angle at 3 days after operation, loss of correction of Cobb angle at 2 years after operation and postoperative complications were observed. Results:All patients were followed up for 25-34 months [(29.9±3.4)months]. The operation time, intraoperative blood loss and times of X-ray exposure on patients in forceful reduction screw group were (69.4±10.2)minutes, (60.3±13.1)ml and (26.8±3.7)times, less than (80.6±11.9)minutes, (80.7±15.4)ml and (30.4±3.4)times in common screw group (all P<0.01). There was no significant difference in anterior height ratio of the injured vertebrae between the two groups before operation and at 3 days after operation (all P>0.05). The anterior height ratio of the injured vertebrae in forceful reduction screw group was (95.5±2.3)% at 2 years after operation, significantly higher than (85.4±1.7)% in common screw group ( P<0.01). There was no significant difference in sagittal Cobb angle of the injured vertebrae between the two groups before operation ( P>0.05). The sagittal Cobb of the injured vertebrae in forceful reduction screw group at 3 days and 2 years after operation were (7.9±1.6)° and (8.8±1.5)°, lower than (10.6±1.1)° and (12.3±1.2)° in common screw group ( P<0.05 or 0.01). There were no significant difference in JOA score and VAS between the two groups before operation, at 3 days and at 2 years after operation (all P>0.05). The degree of correction of Cobb angle in forceful reduction screw group was (19.4±2.5)°, higher than (17.3±2.6)° in common screw group ( P<0.05). The loss of correction of Cobb angle in forceful reduction group was less than that in common screw group at 2 years after operation, but the difference was not statistically significant ( P>0.05). The incidence of postoperative complications in forceful reduction screw group was 12.4% (34/275), compared to 14.1% (41/291) in common screw group ( P>0.05). There were no complications such as iatrogenic nerve injury, fracture or loosening of internal fixator or leakage of bone cement in the spinal canal in both groups. Conclusions:For osteoporotic thoracolumbar burst fracture with kyphosis, forceful reduction and percutaneous pedicle screw internal fixation can significantly shorten operation time, reduce intraoperative blood loss and times of X-ray exposure on patients, restore height of the injured vertebrae, correct kyphosis and maintain reduction height of the injured vertebrae in contrast with conventional percutaneous pedicle screw internal fixation.

ABSTRACT

Objective:To conduct a Meta-analysis of the efficacy and safety of laparoscopy-assisted pylorus-preserving gastrectomy(LPPG) and laparoscopy-assisted distal gastrectomy(LDG) in early gastric cancer(EGC).Methods:Searched Web of Science, Cochrane library, Embase, Chinese Biomedical Medical Database, CNKI, Wanfang Database to identify all qualified studies comparing LPPG and LDG in EGC. The retrieval time was from the database establishment to October 2020. Measurement data with normal distribution were represented as ( Mean± SD). Comparing two groups by mean difference(MD) with 95% confidence interval(CI) for contious outcomes and odds ratio(OR) with 95% CI for dichotomous data.The RevMan software was used to analyze the perioperative outcome. Results:A total of 10 studies were included, with a total of 1613 patients, 624 in the LPPG group and 989 in the LDG group. Operation time, intraoperative blood loss, postoperative anal exhaust time, hospital stay, and overall complication rate of LPPG were similar to LDG.Compared with the LDG group, the LPPG group had fewer lymph node dissections ( MD=-2.51, 95% CI: -4.31~-0.71, P=0.006), longer postoperative gastric tube indwelling time ( MD=1.05, 95% CI: 0.31~1.80, P=0.006), and a higher incidence of delayed gastric emptying ( P<0.01). There was no statistically significant difference between the two groups in terms of other perioperative complications. Conclusion:LPPG is a safe and feasible surgical method for the treatment of EGC, and can be used as an alternative to LDG.

ABSTRACT

Skeletal musculoskeletal disorders which are the focus of osteology are characterized by“structural disorders and functional disability”. How to maximize the restoration of musculoskeletal function at the minimum cost is the goal of osteology. With the innovation of treatment concept and technology,orthopedic biomimetic treatment technique represented by artificial bone and joint replacement has gradually replaced the previous bone and joint fusion surgery and become a new breakthrough in the treatment of musculoskeletal system diseases. By reviewing the development history of biomimetic and on the basis of the original biomimetic medicine,the author puts forward a new concept of orthopaedic bionic treatment(OBT),and expounds its connotation and development in order to explore a new direction to solve the problems of orthopedic treatment. The continuous development of OBT will drive fundamental changes in the treatment of musculoskeletal diseases. The combination of OBT “biomimetic alternative therapy”and“biomimetic natural therapy” will achieve “anatomical reconstruction” and “functional recovery” of skeletal muscle system.

ABSTRACT

Objective:To analyze the incidence and epidemiological characteristics of traumatic spinal cord injury in China in 2018.Methods:Multi-stage stratified cluster sampling was used to randomly select hospitals capable of treating patients with spinal cord injury from 3 regions,9 provinces and 27 cities in China to retrospectively investigate eligible patients with traumatic spinal cord injury admitted in 2018. National and regional incidence rates were calculated. The data of cause of injury,injury level,severity of injury,segment and type of fracture,complications,death and other data were collected by medical record questionnaire,and analyzed according to geographical region,age and gender.Results:Medical records of 4,134 patients were included in this study,with a male-to-female ratio of 2.99∶1. The incidence of traumatic spinal cord injury in China in 2018 was 50.484 / 1 million (95% CI 50.122-50.846). The highest incidence in the Eastern region was 53.791 / 1 million (95% CI 53.217-54.365). In the whole country,the main causes of injury were high falls (29.58%),as well as in the Western region (40.68%),while the main causes of injury in the Eastern and Central regions were traffic injuries (31.22%,30.10%). The main injury level was cervical spinal cord in the whole country (64.49%),and the proportion of cervical spinal cord injury in the Central region was the highest (74.68%),and the proportion of lumbosacral spinal cord injury in the Western region was the highest (32.30%). The highest proportion of degree of injury was incomplete quadriplegia (55.20%),and the distribution pattern was the same in each region. A total of 65.87% of the patients were complicated with fracture or dislocation,77.95% in the Western region and only 54.77% in the Central region. In the whole country,the head was the main combined injury (37.87%),as well as in the Eastern and Central regions,while the proportion of chest combined injury in the Western region was the highest (38.57%). A total of 32.90% of the patients were complicated with respiratory complications. There were 23 patients (0.56%) died in hospital,of which 17(73.91%) died of respiratory dysfunction. Conclusions:The Eastern region of China has a high incidence of traumatic spinal cord injury. Other epidemiological features include high fall as the main cause of injury cervical spinal cord injury as the main injury level,incomplete quadriplegia as the main degree of injury,head as the main combined injury,and respiratory complications as the main complication.

ABSTRACT

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.

ABSTRACT

Objective:To explore the clinical effect of percutaneous vertebroplasty (PVP) at stage I in treatment of acute multi-segment osteoporotic vertebral compression fracture (OVCF) in the elderly with over 3 vertebrae operated.Methods:A retrospective case-control study was conducted to analyze the clinical data of 105 aged patients with acute multi-segment OVCF admitted to Honghui Hospital, Xi'an Jiaotong University from October 2015 to February 2019. There were 27 males and 78 females, aged 65-92 years [(73.0±14.5)years]. All patients received stage I multi-segmental PVP and standard anti-osteoporosis treatment. There were more than 3 operative vertebral segments in 30 patients (observation group) and less than or equal to 3 operative vertebral segments in 75 patients (control group). The operation time, intraoperative fluoroscopy frequency, cement injection volume, cement leakage rate and incidence of recurrent vertebral fractures were compared between the two groups. The visual analogue scale (VAS), Oswestry disability index (ODI) and activity of daily living (ADL) score were compared before operation, 1 day, 1 month after operation and at the last follow-up.Results:All patients were followed up for 11-13 months [(12.5±1.8)months]. The observation group showed operation time of (71.2±12.2)minutes, intraoperative fluoroscopy frequency of (38.8±6.4)times and cement injection volume of (20.2±4.6)ml, more than those in control group [(52.3±10.6)minutes, (25.4±5.3)times, (12.3±4.3)ml] ( P<0.05). There was no significant difference in cement leakage rate and incidence of recurrent vertebral fractures between the two groups ( P>0.05). No complications such as infection, nerve damage or cement implantation syndrome occurred. Before operation, 1 day after operation, 1 month after operation and at the last follow-up, the VAS in observation group [(7.6±0.7)points, (3.0±0.8)points, (2.3±0.7)points, (2.2±0.6)points] showed no significant difference from those in control group [(7.4±0.5)points, (2.9±0.4)points, (2.1±0.5)points, (2.0±0.5)points], the ODI in observation group [(74.6±3.3)%, (36.8±4.6)%, (29.7±4.0)%, (24.0±3.6)%] did not differ from those in control group [(73.8±1.0)%, (35.1±0.9)%, (28.4±2.2)%, (22.8±0.9)%], the ADL score in observation group [(34.5±5.0)points, (54.5±3.8)points, (73.7±3.9)points] were similar with those in control group [(36.2±3.4)points, (56.8±4.7)points, (75.3±5.3)points, (81.3±4.5)points] (all P>0.05). The postoperative VAS, ODI and ADL score in both groups were significantly improved in comparison with preoperation ( P<0.05). Conclusion:For acute multi-segment OVCF in the elderly with over 3 or not more than 3 the vertebrae operated, PVP at stage I has the same advantages in early pain relief and improvement of motor function and quality of life.

ABSTRACT

With the rapid development of China's economy and society, spine and spinal cord injuries mainly due to high-energy injuries caused by high falls and traffic accidents are still the focus in the field of spinal trauma in China. Spine and spinal cord injuries are characterized by high disability rate, many complications, and treatment difficulties, which brings heavy burden to individuals, families and society. During the "13th Five-Year Plan" period, focusing on precise and minimally invasive treatment of spine and spinal cord injuries, a large amount of explorations have been performed in aspects of diagnosis, classification and treatment techniques. The theory of "spinal cord fascia compartment syndrome" and "microenvironment imbalance of spinal cord injury" are creatively put forward. Six national clinical diagnosis and treatment guidelines are formulated and three expert consensuses are issued, which standardizes the clinical diagnosis and treatment practice of spinal and spinal cord injury in China. Three achievements win the second prize of the National Science and Technology Progress Award, representing the highest level in the field of clinical diagnosis and treatment of spine and spinal cord injuries in China during the "13th Five-Year Plan" period. In this article, the authors mainly elaborate the highlights and progress of clinical diagnosis and treatment of spine and spinal cord injuries in China during the "13th Five-Year Plan" period from the perspective of new technoloqy and theory, guideline and consensus and technological awards.

ABSTRACT

Objective:To establish the acute symptomatic osteoporotic thoracolumbar fracture (ASOTLF) classification system, and to examine the reliability and evaluate the effect of clinical application.Methods:A retrospective case series study was conducted to analyze the clinical data of 1 293 patients with osteoporotic thoracolumbar fracture(OTLF) admitted to Honghui Hospital from January 2016 to December 2018. There were 514 males and 779 females, aged 57-90 years [(71.4±6.3)years]. The T value of bone mass density was -5.0--2.5 SD [(-3.1±-0.4)SD]. According to the clinical symptoms a and fracture morphology, OTLF was divided into 4 types, namely type I(I occult fracture), type II(compressed fracture), type III (burst fracture) and type IV(unstable fracture). The type II was subdivided into three subtypes (type IIA, IIB, IIC), and the Type III into two subtypes (type IIIA, IIIB). of all patients, 75 patients (5.8%) were with type I, 500 (38.7%) with type II A, 134 (10.4%) with type IIB, 97 (7.5%) with type IIC, 442 (34.2%) with type IIIA, 27(2.1%) with type IIIB and 18 (1.4%) with type IV. After testing the validity of the classification, different treatment methods were utilized according to the classification, including percutaneous vertebroplasty (PVP) for Type I, PVP after postural reduction for Type II, percutaneous kyphoplasty (PKP) for Type IIIA, posterior reduction and decompression, bone graft fusion and bone cement-augmented screw fixation for Type IIIB, and posterior reduction, bone graft fusion and bone cement-augmented screw fixation for Type IV. The visual analog score (VAS), Oswestry disability index (ODI), Frankel grade of spinal cord injury, local Cobb Angle, and vertebral body angle (vertebral body angle) were recorded in all patients and in each type of patients before surgery, at 1 month after surgery and at the last follow-up. The neurological function recovery and complications were also recorded.Results:The patients were followed up for 24-43 months [(29.9±5.1)months]. A total of 3 000 assessments in two rounds were conducted by three observers. The overall κ value of inter-observer credibility was 0.83, and the overall κ value of intra-observer credibility was 0.88. The VAS and ODI of all patients were (5.8±0.7)points and 72.5±6.6 before surgery, (1.8±0.6)points and 25.0±6.3 at 1 month after surgery, and (1.5±0.6)points and 19.5±6.2 at the last follow-up, respectively (all P<0.05). The Cobb angle and vertebral body angle of all patients were (13.0±9.1)° and (8.0±4.6)° before surgery, (7.9±5.2)° and (4.6±2.9)° at 1 month after surgery, and (9.1±6.0)° and (5.8±3.0)° at the last follow-up, respectively (all P<0.05). At the last follow-up, VAS, ODI, Cobb Angle and VBA of each type of patients were significantly improved compared with those before surgery (all P<0.05). The spinal cord compression symptoms were found 1 patient with type IV and 5 patients with type IIIB preoperatively. At the last follow-up, neurological function improved from grade C to grade E in 1 patient and from grade D to grade E in 5 patients ( P<0.05). The lower limb radiation pain or numbness in 3 patients with type IV and 22 patients with type III preoperatively were fully recovered after surgical treatment at the last follow-up except for three patients. Conclusions:The ASOTLF classification is established and has high consistency and reliability. The classification-oriented treatment strategy has achieved a relatively satisfactory effect, indicating that the classification has a certain guiding significance for treatment of OTLF.

ABSTRACT

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.

ABSTRACT

Spinal cord injury is a serious central nervous system injury, with a high disability rate, many complications and poor prognosis. Although surgical treatment of spinal cord injury has made some progress in the past two decades, it still cannot fundamentally improve the clinical prognosis of patients with spinal cord injury. Stem cell therapy is regarded as one of the most promising treatments in regenerative medicine. Although some achievements have been made in stem cell therapy for spinal cord injury in recent years, such as stem cell transplantation and stimulation of differentiation of autologous potential stem cells, there are still many bottlenecks in its clinical transformation. The authors review the research status of stem cell therapy for spinal cord injury in recent years and prospect its future, hoping to provide references for the further studies.

ABSTRACT

Spinal tuberculosis is one of the common causes of severe kyphosis. The formation of spinal tuberculosis kyphosis is multi-factors, including age at the time of infection, the cumulative number of segments, the height of vertebral body loss before treatment, and "spine danger signs" . Although the use of anti-tuberculosis drugs has achieved good results, for patients with spinal tuberculosis cured by drug treatment, the kyphosis will continue to progress and gradually develop into a severe kyphosis. Then there are a series of problems such as appearance, psychology, rib-pelvic impingement, cardiopulmonary dysfunction, and nerve and spinal cord compression. The X-ray signs of the height of the vertebral body loss and "spine danger signs" before treatment can help predict the severity of future deformities. Therefore, a comprehensive understanding of the formation of kyphosis of spinal tuberculosis and individualized selection of surgical methods according to the specific conditions of the disease as soon as possible can effectively prevent the formation of kyphosis and reduce the incidence of neurological damage and delayed paralysis.

ABSTRACT

Objective:To propose a new grading system-the posterior ligament-bone injury classification and severity (PLICS) score for subaxial cervical spine injury, and evaluate its value in guiding the approach selection for subaxial cervical fracture and dislocation.Methods:All of 394 cases of subaxial cervical fracture and dislocation who received single anterior reduction and fixation in our hospital from January 2002 to December 2015 were retrospectively analyzed. According to the inclusion and exclusion criteria, 354 cases were finally included in this study. The Patients experienced internal fixation failure, postoperative kyphosis or interspinal process space dilation during follow-up were included into the failure group. Other patients were included into the successful group. The difference of visual analogue scale (VAS), neck disability index (NDI), ASIA score and PLICS score before and after surgery between the two groups was compared respectively. The PLICS score is composed of left, right and posterior columns. The injury of the posterior column was classified into mild, moderate and severe degrees, with 1-3 points respectively. The evaluation of lateral column injury included ligament and bone structure. The evaluation of ligament injury included: 1 point for the subluxation of the facet joint, 2 points for the dislocation or the facet joint; Fractures of the lateral column was classified into mild, moderate and severe degrees, with 1-3 points respectively. For the evaluation of the lateral column, the highest score of ligament or bone structure injury was reflected as the score of posterior column injury and was taken into the calculation of the final PLICS score.Results:All 354 patients had complete follow-up data, and the average follow-up time was 18.0±4.0 months, including 339 patients of successful group and 15 patients of failure group. At the 12 month follow-up, the average VAS score of the patients in the successful group decreased from 6.9±0.6 before the operation to 1.9±0.6 ( t=22.481, P<0.0001), and the average VAS score of the patients in the failure group decreased from 5.6±1.0 to 1.1±0.3 ( t=77.252, P<0.0001). The difference between the two groups was statistically significant. The NDI score of the successful group was significantly lower than that of the failure group (7.1%±1.2% vs 15.7%±2.7%, t=24.993, P<0.0001). PLICS score in two groups of patients were analyzed. There was a significant difference in PLICS scores between the two groups ( t=8.777, P<0.0001). According to the PLICS score, the ROC operating curve of the failure of internal fixation after anterior-only surgery was determined. The area under the curve was 0.981, and the 95% confidence interval was 0.943, 1.000. When the PLICS score was 6.5, the maximum value of the Jordan index was 0.927, the sensitivity was 0.994, and the specificity was 0.067. Considering the clinical practicality of PLICS score and the different clinical outcomes of the sub-classification groups of the PLICS score=7, we finally set the threshold as PLICS score=7 with the unilateral severe lateral mass fracture. Conclusion:The PLICS score is based on the anatomy of the posterior three-column structure of the subaxial cervical spine. It gives consideration to the bony structures, including bilateral lateral mass, spinous process, lamina, and the ligament structures. What's more, the overall damage severity of the posterior three columns of the subaxial cervical spine was quantified according to the evaluation of the injury characteristics of each column of ligament-bone structure. In this study, PLICS score and clinical efficacy were compared between two groups of patients, and it was finally determined that when PLICS score ≥7 with the unilateral severe lateral mass fracture, the risk of internal fixation failure is higher for anterior-only approach surgery alone. For these patients, anterior and posterior approach surgery may be considered.

ABSTRACT

Objective:To explore the risk factors of residual back pain (RBP) in patients undergone PVP within 1 month and further analyze the correlation.Methods:Between March 2013 and January 2015, 1 316 patients with OVCF were treated by PVP. RBP after PVP was defined as a visual analogue scale (VAS) score of > 4 both 1 week and 1 month post-operatively. According to the pain relief, the patients were divided into two groups, the satisfied group and the unsatisfied group. All patients were scheduled for follow-up at1 week, 1 month, 3 months, and 1 year post-operatively, during which radiography and magnetic resonance imaging (T1-weighted, T2-weighted, and short time inversion recovery (STIR) sequences) were recommended to detect the existence of secondary OVCF. VAS scores and Oswestry disability index (ODI) were recorded. Demographic data, surgical information, anesthesia method, number of OVCF, injection amount of cement of single vertebral bone, imaging data and other comorbidity informations of patients in the two groups were analyzed by Logistic regression for the factors related to RBP after PVP.Results:Among 1 316 patients, 60 cases complained RBP, and the prevalence was 4.6%. VAS score and ODI of the two groups were significantly different at 1 week, 1 month and 3 months after surgery, suggesting there was a certain degree of residual pain in the lower back of patients in the unsatisfied group, which was more severe than that in the satisfied group. However, the above differences disappeared in the follow-up of 12 months after surgery.Univariate analysesshowed that preoperative bone mineral density (BMD), number of fracture, cement distribution and volume injected per level and lumbodorsal fascia contusion were associated with RBP after PVP ( P< 0.01, retrospectively). Multivariate analysis revealed that the absolute value of pre-operative BMD(odds ratio ( OR)=3.577, P=0.029), combined withlumbodorsal fascia contusion ( OR=3.805, P=0.002), number of fracture ( OR=3.440, P<0.001), satisfactory cement distribution ( OR=3.009, P=0.013) and combined with depression ( OR=3.426, P=0.028) were positively correlated with RBP after PVP, and these were risk factors. The injection amount of cement of single vertebral bone ( OR=0.079, P<0.001) was negatively correlated with RBP after PVP, which was a protective factor. Conclusion:Pre-operative low BMD, lumbodorsal fascial injury, multiple segment OVCF, insufficient cement injected volume, unsatisfactory cement distribution and depression were risk factors associated with RBP after PVP in patients with OVCF.

ABSTRACT

Objective:To assess the effects of preoperative intravenous injection of tranexamic acid and postoperative local use of elastic bandage on blood loss in complex tibial plateau fractures (Schatzker types Ⅴ-Ⅵ).Methods:A sequence randomly generated by computer was used to randomize a cohort of 40 patients into 2 groups who were to receive surgery at Department of Orthopaedics and Trauma, Hong Hui Hospital from June 2018 to January 2019 for complex tibial plateau fractures. They were 24 men and 16 women, aged from 35 to 55 years (average, 46.0 years). In group A, intravenous injection of normal saline was conducted 5 to 10 min before surgical incision and no elastic bandage was used after surgery. In group B, a dose of 15 mg/kg tranexamic acid was intravenously given 5 to 10 min before surgical incision and elastic bandage was used to bandage the knee with compression after surgery. The 2 groups were compared in terms of total blood loss, hidden blood loss, transfusion rate, 48-h drainage flow, venous thromboembolism, postoperative wound complications, postoperative visual analogue scale (VAS), and D-dimer value 24 h after surgery.Results:There were no significant differences between the 2 groups in age, gender, body mass index, smoking history, concomitant medical conditions, American Society of Anesthesiologists (ASA) score, preoperative hemoglobin, preoperative hematocrit, preoperative D-dimerization or fibrin degradation products, showing comparability ( P>0.05). In groups A and B, hemoglobin values 24 h after surgery were 104.6 g/L ± 10.4 g/L versus 113.3 g/L ± 11.9 g/L, drainage volumes 48 h after surgery 277.1 mL ± 229.2 mL versus 207.1 mL ± 124.3 mL, hidden blood loss volumes 318.0 mL ± 83.4 mL versus 266.2 mL ± 60.9 mL, total blood loss volumes 792.8 mL ± 202.8 mL versus 692.2 mL ± 124.9 mL, D-dimer values 24 h after surgery 5.1 mg/L ± 1.3 mg/L versus 4.1 mg/L ± 0.7 mg/L, postoperative VAS scores 5.2 ± 0.9 versus 3.9 ± 1.1, lower limb cross-section diameters 24 h after surgery 35.5 cm ± 3.0 cm versus 34.4 cm ± 2.6 cm, lower limb cross-section diameters 72 h after surgery 33.8 cm ± 2.1 cm versus 32.8 cm ± 2.3 cm, postoperative rates of wound ecchymosis hematoma 20.0% (4 cases) versus 0 (0 cases), and hospital stays 6.6 d ± 1.0 d versus 6.2 d ± 1.2 d. There were significant differences between the 2 groups in all the above items ( P<0.05). However, there were no significant differences between the 2 groups in incidence of postoperative DVT, pulmonary embolism or other wound complications ( P>0.05). Conclusions:Preoperative intravenous injection of tranexamic acid and postoperative local use of elastic bandage is reasonable and safe for complex tibial plateau fractures, because it significantly reduces intraoperative blood loss but does not increase the risk of venous thromboembolism, and thus has a positive role in accelerating the recovery of patients.

ABSTRACT

Objective:To investigate the perioperative risk factors of surgical site infection (SSI) of subaxial cervical spine injury after anterior surgery and provide a basis for the development of nursing measures.Methods:A retrospective case-control study was conducted to analyze the clinical data of 754 patients with subaxial cervical spine injury who underwent anterior surgery from January 2014 to January 2018, including 511 males and 243 females, aged 44-61 years [(50.2±5.1)years]. The fracture segment was C 3 in 60 patients, C 4 in 159, C 5 in 197, C 6 in 236 patients, and C 7 in 102. The patients were divided into two groups according to SSI occurrence. There were 28 patients in infected group and 726 patients in non-infected group. Data of the two groups were recorded, such as demographic data, American Spinal Injury Association (ASIA) scale, comorbidity, time interval from skin preparation to operation, preoperative urinary catheterization or not, consecutive operation or not, total number of staff involved in the operation, layer flow level of operating room, operating room temperature, relative humidity, operation duration, intern nurse involved in the operation or not and surgical methods. Univariate analysis was used to screen the indicators with statistically significant differences between the two groups. Multivariate Logistic regression analysis was further used to identify the risk factors of SSI. Results:The occurrence rate of SSI was 3.71% (28/754). The univariate analysis showed that there were significant differences between the two groups in ASIA scale, diabetes, dietary nursing, time interval from skin preparation to operation, preoperative urinary catheterization, consecutive operation, total number of staff involved in the operation, layer flow level of operating room and operation duration( P<0.01). The multivariate Logistic regression analysis showed that the ASIA scale (grade A: OR= 84.421, grade B: OR=27.200, P<0.01), diabetes ( OR=3.234, P<0.05), without diet nursing ( OR=2.375, P<0.05), time interval from skin preparation to operation ≥ 6 h ( OR=2.542, P<0.05), preoperative urinary catheterization ( OR=4.085, P<0.01), consecutive operation ( OR=2.894, P<0.05), total number of staff in the operating room ≥ 8 ( OR=3.137, P<0.01), layer flow level of operating room is grade 10, 000 or above ( OR=5.380, P<0.01) and operation duration≥ 3 h ( OR=2.405, P<0.05) were positively correlated with perioperative SSI. Conclusions:The factors associated with SSI of subaxial cervical spine injury after anterior surgery are the ASIA scale (grade A and B), diabetes, without diet nursing, time interval from skin preparation to operation ≥ 6 h, preoperative urinary catheterization, consecutive operation, total number of staff in the operating room ≥ 8, layer flow level of operating room (grade 10, 000 or above) and operation duration ≥3 h. For patients with subaxial cervical spine injury, attention should be paid to diet care, blood glucose monitoring should be strengthened, and operating room management should be optimized.

ABSTRACT

Subaxial cervical spine injury refers to cervical spine injury at the segment of C 3-C 7. The morphology and severity of spinal cord injury varied with different mechanism of violence. Different surgeons have deviation in the diagnosis and treatment of subaxial cervical spine injury, with great disputes in the choice of surgical algorithms and approaches. The long-term high disability rate of patients seriously affects their quality of life. Therefore, the reasonable classifications and the surgical method and approach selections of subaxial cervical spine injury are important for accurate diagnosis and high efficiency. With the development of imaging and surgical techniques in recent years, the classification of subaxial cervical spine injury has undergone a change from the speculation of injury mechanism and/or fracture morphology to the emphasis on regional function. Although present classifications can combine imaging and clinical manifestations to some extents and guide clinical diagnosis and treatment, there still lacks classifications widely recognized. Therefore, the authors discuss the diagnosis, classification and treatment of subaxial cervical spine injury so as to provide a reference for standard clinical treatment.
