Objective: To explore the clinical effects of posterior monosegmental pedicle screw fixation in selective treatment of thoracolumbar vertebral fractures.
Methods: From June 2005 to June 2008, 28 patients (male 17 and female 11, the age was 19- 60-years-old with an average of 36 years) with thoracolumbar fractures were treated with posterior monosegmental pedicle screw fixation in our department. According to the AO classification, 19 patients with type A1 fracture and 9 with type A2. The place of pedicle screw and reduction of injured vertebral body were observed.
Results: Postoperative CT scan showed 56 pedicle screws were all placed in the normal part of injured vertebral body. There was no spinal cord injury and infection after surgery. There were restoration of anterior body compression from mean preoperative (42.0 +/- 5.6)% to (12.4 +/- 1.4)% (P<0.05), and restoration of Cobb angle from mean preoperative (25.8 +/- 5.1) degrees to postoperative (1.9 +/- 1.3) degrees (P<0.05). All the patients were followed up for 3-36 months (average in 18.3 months). All fractures achieved bone healing, without significant loss of the vertebrae body height and implant failure.
Conclusion: As indication is correctly choosed, posterior monosegmental pedicle screw fixation can be applied to treat thoracolumbar vertebral fractures.

The aortic-vertebral distance is more associated with axial plane deformities than coronal and sagittal deformities in idiopathic scoliosis patients of Lenke types I and II.

Purpose: Although idiopathic scoliosis is a common three-dimensional deformity, there is a lack of studies evaluating the associations between the aortic-vertebral distance (AVD) and spinal deformities in all planes. The study therefore aimed to evaluate how the coronal and sagittal curvature, vertebral rotation and aortic-vertebral angle (AVA) affect the AVD in idiopathic scoliosis.
Methods: The AVD, AVA, vertebral rotation and curve angles were measured on preoperative magnetic resonance imaging and radiographs in 46 patients who underwent posterior spinal fusion with pedicle screw instrumentation for idiopathic scoliosis Lenke types 1 and 2.
Robotic-assisted Bohlman's technique using SI-LOK implants for high-grade L5-S1 Spondylolisthesis: A case series of three patients.

Background: High-grade Isthmic Spondylolisthesis often requires surgical intervention for spinal realignment and decompression. This study describes a modified Bohlman procedure utilizing robotic-assisted navigation and a Globus SI-LOK interbody device.
Methods: A retrospective review was conducted on three patients who underwent the modified Bohlman procedure for high-grade spondylolisthesis at a single hospital between 2022 and 2023.

Objective: The management of spinal tumors requires a multi-disciplinary approach including surgery, radiation, and systemic therapy. Surgical approaches typically require posterior segmental instrumentation to maintain long-term spinal stability.

3D-printed (3DP) drill guides have demonstrated significant potential to accurately guide pedicle screw insertion in spinal surgery. However, their role in the upper cervical spine is not well established. This review aimed to compare the efficacy and safety of 3DP drill guides to the conventional fluoroscopic-guided free-hand technique for pedicle screw insertion in the upper cervical spine.

Introduction: Congenital lumbar kyphosis is present in about 15% of patients with myelomeningocele. Worsening of deformity with complications such as chronic skin ulcers and bone exposure is common. In patients under 8 years of age, treatment becomes even more challenging: in addition to resecting the apex of the kyphotic deformity, we should ideally stabilize the spine with fixation methods that do not interrupt the growth of the rib cage, associated with the challenging pelvic fixation in this population.
