Abstract
Background. Diagnosis and treatment of patients with malignant bone tumors requires continuous improvement of existing methods of diagnosis and treatment. Purpose: to improve the treatment results in patients with tumors of the femur and pelvis through the application of medical imaging technologies, 3D modeling and 3D printing of personalized models of bones and tumors, arthroplasty and bioactive ceramics. Materials and methods. Examination, treatment and monitoring of 28 patients with malignant tumors of the bones of the pelvis, lower extremities and examination of 16 apparently healthy people were performed. Computed tomography (CT) and magnetic resonance imaging (MRI), 3D modeling, biochemical markers of bone metabolism, arthroplasty, biomine were applied. Results. The technology of creating a 3D model of bones affected by malignant tumors has been developed based on the results of MRI, CT and 3D printing. Preoperative planning and training on 3D models reliably reduced intraoperative blood loss, duration of surgery, time of complete recovery of the extremity function, the risk of postoperative complications and, accordingly, increased the duration of the first recurrence-free period. The use of bone resorption and osteosynthesis markers allows to control the osseointegration of endoprosthesis and biomine, to diagnose recurrence/metastasis timely. Conclusions. The application of CT + MRI + 3D modeling + training on 3D models + tumor removal + arthroplasty + biomine algorithm provided functional results after 12 months: excellent — in 57.35 %, good — in 29.41 % of cases. Postoperative complications were observed only in 12.2 % of patients, local recurrences — in 7.3 %.
期刊介绍:
The first open access journal in the field of burns and trauma injury in the Asia-Pacific region, Burns & Trauma publishes the latest developments in basic, clinical and translational research in the field. With a special focus on prevention, clinical treatment and basic research, the journal welcomes submissions in various aspects of biomaterials, tissue engineering, stem cells, critical care, immunobiology, skin transplantation, and the prevention and regeneration of burns and trauma injuries. With an expert Editorial Board and a team of dedicated scientific editors, the journal enjoys a large readership and is supported by Southwest Hospital, which covers authors'' article processing charges.
