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

Minimally invasive percutaneous fixation of cases having thoracolumbar vertebral fractures without neurological impairments has remained controversial. The advantages of minimally invasive percutaneous fixation are decreasing muscle and soft tissue injury, decreasing blood loss and infection rate, in addition to shortening hospital stay and recovery times. In comparison to the open technique, percutaneous fixation is adequate for treating thoracolumbar (TL) fractures without causing neurological impairments & with satisfactory outcomes in terms of kyphosis decline. Elevated radiation exposure to the surgeon &the patient, lack of decompression and fusion via bone graft, & a steep learning curve are all disadvantages of percutaneous fixation of vertebral fractures. Methods: This study was retrospectively conducted on forty-eight patients, age ranging from 16 to 65 years old, with a thoracolumbar (TL) fracture without causing neurological impairments who were meeting the eligibility criteria for fixation in the period from July 2019 to January 2024. Results: We included the forty-eight patients who met the inclusion criteria (34 males and 14 females) their ages ranged from 16 to 65 years. The most common pathology was L1 fracture in 38 patients. No major complications were experienced, only wound infection in five patients which was treated efficiently with repeated dressings and broad-spectrum antibiotics. Four patients experienced misdirected screws, only in one patient the screw encroach into the spinal canal with no deficit experienced, while the other three showed minimally laterally deviated screws. Conclusion: The advantages of percutaneous pedicle screw fixation in thoracolumbar fractures through preservation of posterior musculature, are less blood loss, shorter operative time, lower infection risk, less post-operative pain, shorter rehabilitation time as well as a shorter hospital stay. Limitations of percutaneous fixation include the inability to achieve direct spinal canal decompression and, not having the option to perform a fusion and also requiring a learning curve to master the anatomy and technique.展开更多

Seventy patients with thoracrolumbar vertebrate fractures were treated by short-segment pedicle screw fixation and were randomly divided into two groups. Fractures in group A （n=20） were rein-forced with posterior morselized bone grafting in vertebrae for spinal fusion, while patients group B （n=50） did not receive the morselized bone grafting for bone fusion. The two groups were compared in terms of kyphotic deformity, anterior vertebral height, instrument failure and neurological functions after the treatment. Frankel grading system was used for the evaluation of neurological evaluation and Denis scoring scale was employed for pain assessment. The results showed that the kyphosis correction was achieved in both group A and group B （group A： 6.4 degree; group B： 5.4 degree）/At the end of follow-up, kyphosis correction was maintained in group A but lost in group B （P=0.0001）. Postoperatively, greater anterior height was achieved in group A than in group B （P〈0.01）. During follow-up study, anterior vertebral height was maintained only in Group A （P〈0.001）. Both group A and group B showed good Denis pain scores （P1 and P2） but group A outdid group B in terms of control of severe and constant pain （P4 and P5）. By Frankel criteria, the changes in neurological functions in group A was better than those of group B （P〈0.001）. It is concluded that reinforcement of short-segment pedicle fixation with morselized bone grafting for the treatment of patients with thoracolumbar vertebrae fracture could achieve and maintain kyphosis correction, and it may also increase and maintain anterior vertebral height. Morselized bone grafting in vertebrae offers immediate spinal stability in patients with thoracolumbar vertebrate fractures, decreases the instrument failure and provides better postoperative pain control than without the morselized bone grafting.展开更多

文摘This study aimed to introduce a novel mini-open pedicle screw fixation technique via Wiltse approach, and com- pared it with the traditional posterior open method. 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.

文摘Thoracic spine fracture is a common orthopedic injury that is usually caused by external forces acting directly on or transmitted to the thoracic spine through other parts of the spine.Thoracic spine fractures can be divided into two types:stable and unstable.An unstable fracture means that the relationship between the vertebral bodies is no longer stable,which may cause serious consequences such as spinal compression,nerve root compression,or spinal cord injury.Surgical treatment is often needed for patients with unstable fractures,nerve root compression,or spinal cord injury to restore stability and function to the thoracic spine.The probability of complications after thoracolumbar fracture surgery is high,which affects the outcome of surgical treatment.To improve postoperative rehabilitation outcomes,this article analyzed the value of nursing care based on the enhanced recovery after surgery(ERAS)concept for patients undergoing thoracolumbar fracture surgery.

文摘BACKGROUND The combined anterior/posterior approach appears to be capable of reconstructing spinal stability,correcting thoracolumbar deformity,and promoting neural recovery in severe thoracolumbar fracture dislocation.However,this type of operation requires changing the body position during the procedure,resulting in a lengthy operation time.As a universal surgical robot,TINAVI robot has achieved good surgical results in clinical surgery.But to our knowledge,no reports describing TINAVI robot-assisted single lateral position anteroposterior surgery for thoracolumbar fracture dislocation.CASE SUMMARY We describe a case of a 16-year-old female patient with severe thoracolumbar fracture and dislocation underwent surgery assisted by the TINAVI robot.A onestage combined anterior and posterior operation was performed on a severe thoracolumbar fracture dislocation using the TINAVI robot,and the operation was completed in right lateral position.CONCLUSION The TINAVI robot-assisted one-stage anterior and posterior surgery in right lateral position for severe thoracolumbar fracture and dislocation is both safe and effective.

文摘To enhance the fusion of graft bone in thoracolumbar vertebrae and minimize the postoperative loss of correction, short-segment pedicle screw fixation was reinforced with posterior moselizee bone grafting in vertebrae for spinal fusion in patients with thoracrolumbar vertebrate fractures. Seventy patients with thoracrolumbar vertebrate fractures were treated by short-segment pedicle screw fixation and were randomly divided into two groups. Fractures in group A （n=20） were rein-forced with posterior morselized bone grafting in vertebrae for spinal fusion, while patients group B （n=50） did not receive the morselized bone grafting for bone fusion. The two groups were compared in terms of kyphotic deformity, anterior vertebral height, instrument failure and neurological functions after the treatment. Frankel grading system was used for the evaluation of neurological evaluation and Denis scoring scale was employed for pain assessment. The results showed that the kyphosis correction was achieved in both group A and group B （group A： 6.4 degree; group B： 5.4 degree）/At the end of follow-up, kyphosis correction was maintained in group A but lost in group B （P=0.0001）. Postoperatively, greater anterior height was achieved in group A than in group B （P〈0.01）. During follow-up study, anterior vertebral height was maintained only in Group A （P〈0.001）. Both group A and group B showed good Denis pain scores （P1 and P2） but group A outdid group B in terms of control of severe and constant pain （P4 and P5）. By Frankel criteria, the changes in neurological functions in group A was better than those of group B （P〈0.001）. It is concluded that reinforcement of short-segment pedicle fixation with morselized bone grafting for the treatment of patients with thoracolumbar vertebrae fracture could achieve and maintain kyphosis correction, and it may also increase and maintain anterior vertebral height. Morselized bone grafting in vertebrae offers immediate spinal stability in patients with thoracolumbar vertebrate fractures, decreases the instrument failure and provides better postoperative pain control than without the morselized bone grafting.

文摘Thoracolumbar fractures are usually treated by open posterior pedicle screw fixation.However,this procedure involves massive paraspinal muscle stripping,inflicting surgical trauma,and prolonged X-ray exposure.In this study,we observed 127 patients with single-segment injury thoracolumbar fractures.Thirty-six patients were treated by the modified Wiltse’s paraspinal approach with minimally invasive channel system,while 91 patients were treated via traditional posterior approach.Operation time,intraoperative blood loss,intraoperative fluoroscopy frequency,screw placement accuracy,visual analogue scale score,and Cobb’s angle of two groups were compared.The X-ray exposure times were notably reduced(4.2±1.6) in the new approach group(P<0.05).The pedicle screw placement accuracy and Cobb’s angle after surgery were similar in the two groups.We conclude that modified Wiltse’s paraspinal approach w ith spinal minimally invasive channel system surgery can significantly reduce the X-ray exposure times and is an alternative therapy for the thoracolumbar fracture.
文摘Objective: To evaluate the clinical effect of AF instrument in treating thora-cohtmbar fracture and to summarize the lesson of operation's fault. Methods : Fifty-four cases with thoracolumbar fracture were reviewed. Preoperative and postoperative of all patients,X-ray pictures, CT, MR and ASIA classification were studied and evaluated contrastively. Results: The main Cobb's angle of all 47 cases that had been followed up was corrected from 24. 5° preoperatively to 5. 5° post-operatively. Anterior height of compressed vertebral bodies restored from 53% preoperatively to 91% postoperatively. According to ASIA classification, the injury of nerves progressed 1-3 grade. The complications appeared in about 19. 1%. Conclusion- AF instrument can achieve anatomical reduction and stable interior fixation. It is one of the best devices for the treatment of thoracolumbar fracture. To improve the operators, surgical technique is the key in decreasing the complications.

文摘Background Short-segment U-shaped pedicle screw fixation has been widely used to treat thoracolumbar burst fracture.Some studies have reported the disadvantages of traditional U-shaped pedicle screw,which included a relatively high rate of adjacent segment degeneration and screw failure,including screw pullout and breakage.The purpose of this study was to assess the efficacy of open reduction and fixation using KumaFix fixation system in treatment of thoracolumbar burst fractures.Methods From June 2011 to June 2012,45 consecutive patients with thoracolumbar burst fractures were enrolled.They were randomly assigned to treatment with KumaFix （the treatment group,n=23） or traditional U-shaped pedicle screw （the control group,n=22）.The patients were followed up postoperatively and were assessed with regard to radiologic and clinical outcomes.Radiologic outcomes were assessed mainly on the basis of Cobb angle and vertebral wedge angle.Clinical outcomes were evaluated mainly with use of Visual Analog Scale （VAS） for pain and the Oswestry Disability Index （ODI） Questionnaire.Results All patients were followed up from 9 to 22 months.There were no significant differences between the two groups with regard to preoperative indices.The operation time in the treatment group was significantly lower than that in the control group.Preoperative Cobb angles and vertebral wedge angles in two groups were significantly decreased after surgery,and these have been well maintained at the last follow-up with mild correction losses.The results of clinical outcome showed lower VAS and ODI scores in two groups compared with those preoperative,and the treatment group had greater improvement on the ODI compared with the control group at the last follow-up.Conclusions Compared with traditional U-shaped pedicle screw,KumaFix fixation system can achieve gradual,controlled reduction,provide enough space for bone implantation,and avoid acceleration of adjacent segment degeneration.It is an effective and reliable technique to treat thoracolumbar burst fractures.
文摘Thoracolumbar burst fracture, a common condition in clinic, often leads to severe spinal instability and neurologic deficit. In most cases, the compression that caused by backward protrusion of the fracture fragments to the spinal cord, makes complete decompression difficult through a posterior approach. Here, we reviewed the clinical records of 22 patients with thoracolumbar burst fracture treated by anterior corpectomy, decompression of the spinal cord, and implantation of titanium mesh cage.
