“…Therefore, an alternating methodology of investigation of vertebrae mechanical properties can be 3-D printing. As is stated in Reference [52], today, 3-D printing is practical, useful technology in surgical planing or spine implantation. Obviously, knowing mechanical characteristics, 3-D printed vertebrae is the basic step in successful applications of such kind of structures.…”

FEM-Based Compression Fracture Risk Assessment in Osteoporotic Lumbar Vertebra L1

et al. 2019

This paper presents a finite element method (FEM)-based fracture risk assessment in patient-specific osteoporotic lumbar vertebra L1. The influence of osteoporosis is defined by variation of parameters such as thickness of the cortical shell, the bone volume–total volume ratio (BV/TV), and the trabecular bone score (TBS). The mechanical behaviour of bone is defined using the Ramberg–Osgood material model. This study involves the static and nonlinear dynamic calculations of von Mises stresses and follows statistical processing of the obtained results in order to develop the patient-specific vertebra reliability. In addition, different scenarios of parameters show that the reliability of the proposed model of human vertebra highly decreases with low levels of BV/TV and is critical due to the thinner cortical bone, suggesting high trauma risk by reason of osteoporosis.

Background: Total hip arthroplasty(THA) is a good solution of developmental dysplasia of the hip(DDH). However, patients diagnosed with Crowe type IV are difficult to deal with. With traditional operation skills, the operation time is quite long and the patients will lose a lot of blood.Case presentation: We present the case of a 58-year-old male patient who underwent left THA due to Crowe type IV DDH with the help of 3D printing models. Before the operation, we put the CT image into a computer software named mimics. After getting the stl. document, we use 3D printer to print the models out. By using the models, wo planned the operation in advance. And after sterilizing the models, we put them in the operation area, which saves a lot of operation time and reduces much blood loss by giving surgeons a better anatomy view. Conclusion: THA with the help of 3D printing pelvis and femur can result in a relatively short recovery time and provide good clinical efficacy of type IV DDH patients.

Данная технология получает все более широкое распространение в связи с повышением доступности 3D-печати.…”

Surgical treatment of advanced congenital kyphoscoliosis: A case report

et al. 2018

View full text Add to dashboard Cite

Clinical case of surgical treatment of advanced congenital kyphoscoliosis in 12 years old child is reported. Radiographs and CT at presentation failed to reveal the entire anomaly. By analysis of priorly made radiographs hemivertebra L1 was recognized. At genitourinary assessment L-shaped kidney was detected. A full-size 3D-printed model was used for surgical planning. Vertebral column resection as treatment option was discussed, but due to high neurologic complication rate this approach was refused. After preoperative 35 days halo-femoral traction anterior instrumented fusion was performed. Right ureter was stented for intraoperative urologic injury prevention. Scoliosis correction of 32% and kyphosis of 14% was achieved. 5 months later definitive posterior uninstrumented fusion was performed. Spinal deformities caused by vertebral malformations progress dramatically unless they are treated early. An advanced case is a clinical challenge because of technical difficulties and poor result. Vertebral column resection is a treatment option for severe kyphoscoliosis, but it’s indications should be strictly individualized. Preoperative halo-femoral traction is the most safe correction method in spinal deformity due to prolonged and gradual action. 3d-printed models are practical for surgical planning. The model may be used intraoperatively as a 3D-reference. In congenital scoliosis genitourinary system should be assessed meticulously, and urologist advice in relevant case is necessary.
