The "Optimum Volume" of Acrylic Cement Filling for Treating Vertebral Compression Fractures: A Morphometric Study of Thoracolumbar Vertebrae.

The "Optimum Volume" of Acrylic Cement Filling for Treating Vertebral Compression Fractures: A Morphometric Study of Thoracolumbar Vertebrae. Adv Exp Med Biol. 2019 Aug 20;: Authors: Dzierżanowski J, Winklewski PJ, Skotarczak M, Baczkowska-Waliszewska Z, Szmuda T, Zdanowski S, Radkowski M, Łuczkiewicz P, Czapiewski P, Słoniewski P, Szurowska E, Demkow U, Szarmach A Abstract Percutaneous vertebroplasty is a treatment option in vertebral compression fractures (VCF). The aim of the study was to propose the mathematical calculation of the "optimum volume" of acrylic cement filling of the vertebral body, depending on the severity of a fracture. Two hundred computed tomography (CT) scans of vertebral columns in healthy adult Caucasians were analyzed. Vertebral body width (VBW), vertebral body depth (VBD), vertebral body height (VBH), and vertebral body volume (VBV) were measured. The "optimum volume" of cement injections in mild (25% collapse) and moderate (40% collapse) VCF were calculated. We found that moving caudally from Th11 to L2, the mean values of the examined parameters increased: VBH from 22.6 to 26.0 mm, VBW from 34.0 to 39.5 mm, VBD from 28.1 to 30.9 mm, and VBV from 17.1 to 24.8 cm3. The calculated hypothetical "optimum volume" of cement injection increased from 7.4 to 10.0 cm3 in mild VCF and from 5.9 to 7.8 cm3 in moderate VCF, with some variability depending on the vertebral level and gender. These val...

Conclusions: We recommend an algorithm that favors radiographs with comparison study or acquiring either MRI or bone scan to determine acuity. If these are available, CT scan becomes unnecessary and incurs increased costs and radiation exposure.

This study was a retrospective review of prospectively collected data of consecutive patients with A1.2 thoracolumbar compression fractures treated by PVP. Vertebral BMD was measured before surgery and participants were divided into 3 groups according to World Health Organization diagnostic criteria for osteoporosis: Group A (normal BMD), Group B (reduced BMD), and Group C (osteoporosis). All vertebrae were injected with 3 mL of bone cement via the unilateral pedicle and scanned by computed tomography after surgery. Actual injection volume (bone cement only) and total diffusion volume (bone cement plus trabeculae and spa...

Conclusionin patients with pulmonary cement embolism, conservative treatment may be recommended rather than a surgical removal except when the obstruction is extensive enough to cause hemodynamic changes. Given that all the related studies have suggested that pulmonary thromboembolism can occur as a complication due to bone cement leakage, discovering new cement alternatives and/or injection devices, seems beneficial.

Rationale: Benign metastasizing leiomyoma (BML) is rare condition involving distant metastases secondary to benign uterine leiomyoma, and it is most commonly found in the lungs. It rarely metastasizes to the spine to cause osteolytic damage and spinal canal compression. Patient concerns: A 51-year-old woman with low back and bilateral leg pain and paresthesia was admitted to our ward. She has a previous medical history of uterine leiomyomas. Magnetic resonance imaging of the lumbar spine revealed vertebral body osteolytic destruction and soft tissue mass in the L4/5 with a secondary lumbar spinal stenosis. Positron em...

Conclusion: Multilevel PV for the treatment of osteoporotic fractures is a safe and successful procedure that can significantly reduce pain and improve patient's condition without a significant morbidity. It is considered a cost effective procedure allowing a rapid restoration of patient mobility. PMID: 29940724 [PubMed - as supplied by publisher]

CONCLUSIONS: The operator should frequently check to ensure that cement injection has stopped upon reaching the SL. Surgeons may benefit from this quantitative anatomical study of PKP and PVP. PMID: 29883213 [PubMed - as supplied by publisher]

In conclusion, the novel precise 3-dimensional printing guide template system may allow (1) comprehensive visualization of the fractured vertebral body and the individual surgical planning, (2) the perfect fitting between skin and guide template to ensure the puncture stability and accuracy, and (3) increased puncture precision and decreased puncture-related complications, surgical time and radiation exposure.

Publication date: February 2018 Source:Orthopaedics & Traumatology: Surgery & Research, Volume 104, Issue 1, Supplement Author(s): C. Mazel, L. Ajavon Thoracolumbar malunion is the result of loss of correction, insufficient correction or even no correction (both in the frontal and sagittal planes) of a thoracolumbar fracture. The main causes are incorrect assessment of the fracture's complexity (burst fracture), its potential progression to kyphosis and associated disc or ligament damage. It can also be the result of a poorly conducted initial treatment. The types of malunion have changed over the years because of...

In this study, we developed a three-dimensional (3D) finite-element (FE) model of the spinal T12-Pelvis segment by using CT scan data of lumbar spine of an adult woman with no physical abnormalities. By modulating model parameters we further simulated osteoporotic conditions of the T12-Pelvis FE model with or without polymethyl methacrylate (PMMA) augmentation. Dynamic characteristics of the osteoporotic T12-Pelvis model were detected at the first order of vertical resonant frequencies (FOVRFs) under vertical vibration, which included vertical axial displacements, anteroposterior (AP) displacements and rotational angles of...
