Objective: To explore the clinical efficacies of intermediate screws plus injectable calcium sulfate MIIGX3 for thoracolumbar fracture in postmenopausal patients.
Methods: A total of 21 postmenopausal patients with vertebral compression fractures reconstructed with posterior internal fixation of intermediate screws technique and anterior vertebral augmentation of MIIGX3 technique in three dimension were retrospectively analyzed. The changes of fracture vertebral height and Cobb's angle were compared.Visual analogue scale (VAS) was performed to evaluate their symptoms. All patients were followed up.
Results: Intermediate screws surgical technique plus MIIGX3 was successfully performed. The average injection dose was 4.6 ml.Leakage occurred intraoperatively in two cases. The average follow-up period was 15 (6-36) months. The VAS system demonstrated that pain decreased significantly (preoperative:7.8, postoperative:2.2). The height and Cobb's angle of fractured vertebra improved greatly. The preoperative values were 45.0 ± 6.4% and 19.4 ± 4.5° and postoperative ones 15.4 ± 3.9% and 8.64 ± 3.18° respectively. There was no occurrence of severe complications related with treatment.Except for 2 patients with a loss of 15% of vertebral height, the average heights of fractured vertebra in other 19 patients recovered to 85% of normal ones.
Conclusion: Thoracolumbar fracture in postmenopausal patients may be managed satisfactorily by intermediate screws and injectable calcium sulfate technique.Such a technique is both safe and effective. And its stable and durable reduction offers significant improvement.

: Thoracolumbar and lumbar spine injuries account for 30-60% of spinal fractures, especially at the thoracolumbar junction. Conservative treatment is recommended for stable fractures without neurological symptoms, but studies suggest surgical intervention may offer better outcomes. However, there is no consensus on the best stabilization method.

The existence of stress singularities and reliance on linear approximations pose significant challenges in comprehending the stress field generation mechanism around dislocations. This study employs differential geometry and calculus of variations to mathematically model and numerically analyse screw dislocations. The kinematics of the dislocation are expressed by the diffeomorphism of the Riemann-Cartan manifold, which includes both the Riemannian metric and affine connection.

Article Synopsis
- * Materials and Methods: Twelve Ti and twelve Zr implants were placed in human mandibles with half simulated for bone graft loss. CBCT images were taken with varied MAR settings, and five evaluators assessed graft loss using a scoring system.
- * Results: Using MAR on the OP300 unit improved diagnostic accuracy for both implant types, while extreme MAR mode on the Eagle 3D unit decreased accuracy. Overall, Ti implants showed higher diagnostic values than Zr implants.

Giant cell tumors (GCTs) of bone are classified as intermediate malignant tumors with a significant potential for local infiltration. Despite their benign histopathological appearance, these tumors exhibit extreme local aggression. The sacrum is the most commonly affected spinal region, followed by the lumbar, cervical, and thoracic regions.

Introduction: Thoracolumbar fractures make up majority of the spinal fractures. Various techniques including long, short, mono and short segment screw fixation have been used to achieve stability. There are still few studies describing the results of short segment fixation with intermediate screw fixation in fractured vertebrae, despite the fact that all have adequate efficacy and stability.
