Thoracolumbar Spine Fracture-Dislocation without Neurological Deficit: A Case Report and Review of the Literature

Background: Thoracolumbar spine fracture-dislocations are very unstable and usually secondary to high energy trauma. Due to disruption of the entire vertebrae columns, the absence of neurological deficit is exceptional. Aim: The purpose of this work is to report our experience in the management of this entity in a context of limited resources and to make a review of the literature. Case presentation: A 30-year-old man was admitted with a severe low back pain after a traffic accident. Neurological functions were intact after examination. Radiological assessments revealed a complete L3-L4 fracture-dislocation. The patient underwent an open posterior reduction and internal long segment fixation. The post-operative was marked by a surgical site infection treated with surgical debridement and targeted antibiotic therapy. The neurological functions were preserved. Conclusion: Fracture-dislocations of the thoracolumbar spine are caused by high energy trauma and are remarkably unstable lesions. When they are associated with intact neurorological functions, reduction and stabilization of these fractures are a challenge.

Exploration and Discussion on the Clinical Therapeutic Effects of the Application of Cross-Injury Vertebral Fixation and Via-Injury Vertebrae Fixation in the Treatment of Bone Tumor with Thoracolumbar Spine Fracture

Objective:To explore and discuss the clinical therapeutic effects of the application of cross-injury vertebral fixation and via-injury vertebrae fixation in the treatment of bone tumor with thoracolumbar spine fracture.Methods:A total of 58 patients with bone tumors and thoracolumbar spine fractures admitted to our hospital from February to February 2019 were selected as the study subjects.They were randomly divided into control group and observation group,with 29 cases in each group.The patients in the control group received cross-injury vertebral fixation treatment,while the patients in the observation group were treated with via-injury vertebral fixation.The therapeutic effects of the two groups were compared.Results:The operation time and hospitalization time of the observation group were significantly shorter than those of the control group(P<0.05),and the postoperative drainage volume of the intraoperative blood loss was significantly less than that of the control group(P<0.05).There was no significant difference in postoperative pain and spinal JOA scores between the two groups(P>0.05);there was no significant difference in the compression ratio of the injured vertebrae and the kyphosis Cobb angle between the two groups(P>0.05),after the operation,the two groups of patients were significantly reduced,and the compression ratio of the injured vertebrae and kyphosis Cobb angle of the observation group were more obvious(P<0.05);the vertebral height loss and Cobb angle loss in the observation group were significantly lower than those in the control group(P<0.05).Conclusion:In the treatment of bone tumor with thoracolumbar spine fracture,compared with cross-injury vertebral fixation,via-injury vertebral fixation has a more significant clinical effect and is more suitable for clinical application and promotion.

TINAVI robot-assisted one-stage anteroposterior surgery in lateral position for severe thoracolumbar fracture dislocation:A case report

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.

C1C2 Wiring and Posttraumatic Atlantoaxial Dislocation: An Effective and Cheap Surgical Procedure in a Developing Country

Objectives: Atlantoaxial dislocation remains a rare and serious condition with a high preoperative and postoperative morbidity and mortality. Its successful surgical management is still challenging and gratifying for neurosurgeons. Several technics have been described such as wiring, trans articular screwing, C1C2 screwing with plate and screw introduced by Goel et al., and modified by insertion of polyaxially screw and rod many years later by Harms. Unavailability and expensiveness of upper cervical spine instrumentation device led us to C1C2 Wiring resulting in a good outcome. Finally, a quadriplegic patient with a more comfortable financial condition had ordered devices from abroad and benefit for Goel and Harms screwing technique and improved dramatically from ASIA A to ASIA E. Material and methods: This is a retrospective study of patients managed in our department by a same neurosurgeon from January 2019 to April 2024. Results: We defined 6 men and 1 woman with an average age of 33 years. Unrestrained driver in a rollover motor vehicle accident was most common. Only one patient was neurologically intact on admission. Neurovegetative disorders were noticed in one patient. Dislocation was associated to a fracture of the dens in two patients. Three patients have been successfully operated with remarkable outcome, mostly from ASIA A to E. Conclusion: C1C2 dislocation is a serious condition and C1C2 Wiring represents an effective and cheaper technic. Therefore, this technic should deserve consideration above all in low incomes countries when screwing devices are not available. Seatbelt should be demanded for motor vehicle drivers and passengers.

Then the surgical related indicators, JOA score, the reduction of injured vertebrae and complications were recorded and compared between groups at different time points, including, before operation (T0), postoperative 1mon (T1), postoperative 6mon (T2) and postoperative 12mon (T3).Results: The operation time, intraoperative X-ray fluoroscopy frequency and intraoperative blood loss in the study group were significantly lower than those in the control group (P<0.05), meanwhile the accuracy rate of screw placement was significantly higher than that of the control group (P<0.05). JOA scores at T1, T2 and T3 in both groups were significantly higher than those at T0 (P<0.05), and JOA scores at all postoperative time points in the study group were significantly higher than those in the control group (P<0.05). Compared with T0, the ratio of the anterior and posterior border height of injured vertebrae in the two groups at T2 was significantly increased (P<0.05), while the Cobb Angle of sagittal kyphoid significantly was decreased (P<0.05). Meanwhile, the reduction of injured vertebrae in the study group was significantly better than that the control group at T2 (P<0.05). The incidence of complications in the study group was significantly lower than that in the control group (P<0.05).Conclusion: The application of 3D printing assisted pedicle screw placement in the treatment has the advantages of less injury to patients, good prognosis and high safety, which is worthy of clinical application.

Surgical Management of an Unstable Lumbar Fracture-Dislocation—A Case Report

The lumbar spine is the most common sites for fractures because of the high mobility of the lumbar spine. A spinal cord injury usually begins with a sudden, traumatic blow to the spine that fractures or dislocates vertebrae. A 32-year-old man presented to us after traffic accident. In our patient, unstable fracture-dislocation of the lumbar spine at the L2-L3 level due to traffic accident occurred. The vertebral bodies were fractured and the anterior dislocation happened without spinal cord injury. The patient was a candidate for an open reduction and internal fixation surgery. The posterolateral approach was performed. After insertion of all the pedicle screws, the rods were transversally placed on L2-L3-L4 vertebral bodies and tightened. The reduction of the dislocations was carried out by pushing downwards (foreside) L2 and L4 vertebras and upwards (backside) L3 vertebrae, simultaneously. After securing the reduction of the dislocations, the rods were opened and placed along the spinal column and tightened. This technique is more effective when the pedicle of fractured vertebrae is intact.
