Scoliosis Of Three-dimensional Reconstruction Of Internal Organs

Scoliosis in the Greek said Scoliosis, Galen (AD 131-201 years) the first name terms with this. Scoliosis is the most common spinal deformity, as early as the Hippocratic era to the spinal curvature has been described. Andree in 1741 with a curved spine, orthopedic surgery as the marker. Scoliosis is defined as spinal X-ray pictures before and after there are more than 100, a curved side edge to side edge as a result of a curved spine, the curvature of the scope of the vertebral body rotation occurs, the Secretary-dimensional deformation of a lead to the malformation complex next abnormal power side: (1) vertebral body in the sagittal plane are extended to the spine lateral protrusion Duan; (2) the amount of surface-shaped vertebral body tilted to one side; (3) rotation axis so that the surface has spinal distortions, the main deformation in the arc of the top progressive deformity, thoracic vertebrae and structural changes may occur in intra-abdominal organs and thoracic spinal cord of the anatomical relationship to each other progressive disorders, and impaired organ function does not found. From the etiology of scoliosis is divided into: 1, congenital / dysplastic scoliosis, 2, adolescent idiopathic scoliosis, 3, paralytic scoliosis.Scoliosis treatment more effective is the 50’s began Rinse :’s plaster after correction and fusion law, 60 since the early advent of law Harrinnton surgery so that the treatment of scoliosis has been a qualitative leap. China’s treatment of scoliosis began in the late 70s’ use of Harrinnton surgery. Over the past 10 years, there has been a variety of surgical procedures’ such as the posterior surgery: Harrinnton surgery ’Luque operation’ a joint Harrinnton - Luque operation ’Galveston surgery, C - D operation, TSRHI and the "Chinese Wall" operation, such as: anterior spinal mobilization, hemivertebra anterior resection, DWYER, such as surgery and surgery Zlelke, throughout the country in the months to promote and applications. Orthopedic surgery is an effective treatment method of severe scoliosis. However, due to the difficulty of high surgical risk, and it has been the orthopedic surgeon’s field of concern. Clinical implementation of the current operation, and mainly relied on the experience of surgery in general is estimated. With a large number of high-precision clinical emergence of medical imaging equipment and high-speed computer use, making a short in the past 30 years, medical imaging technology has made significant improvement. X-ray computed tomography (Computed Tomography, CT), Ultrasound (Ultrasound), magnetic resonance, digital subtraction (DigitalSubstration Angiography, DSA), Positron Emission Tomography (Positron Emission Tomography, PET), single photon emission computed tomography (Single Photon Emission-CT, SPECT) and other advanced imaging technology has been successfully used in clinical, is becoming a clinical study, diagnosis and treatment of essential and conventional means to provide people with a wealth of valuable information of image data, but also to promote Research on medical image segmentation of the further development of surgical navigation in the (Image-Guided Surgery), simulated surgery (Surgical Simulation), treatment evaluation (Therapy Evaluation), functional images of the partial volume correction (PartialVolume Correction) and computer-aided diagnosis (Computer - Aided Diagnosis), such as computer-assisted surgery (computer-assisted surgery, CAS) technology development and rapid development of an integrated science, computer-aided image data by the surgeon to perform an operation to replace the three-dimensional idea of the program can be reasonable, and quantitatively the development of surgical programs, and the choice of the path of the best surgery, surgery to reduce injury and reduce damage to adjacent tissues, to improve positioning accuracy, the implementation of complex surgical procedures and improve the success rate of such surgery is very important, and the information available for the entire operation group members to share. However, current research focuses on scoliosis surgery, little research for patients with scoliosis before and after the comparative study of internal organs to correct. The introduction of computer-aided design issues scoliosis correction before the tracheobronchial lung, pulmonary artery and three-dimensional reconstruction model of the kidney.Research purposes(1) as a preoperative medical assessment;(2) on human tissues and organs of the border, such as sectional area and volume measurements. Before and after treatment by measurement of these indicators and analysis to help doctors in diagnosis, formulation and revision of the treatment of patients;(3) three-dimensional medical image reconstruction and visualization of the foundation, can be used for program development and operation simulation, after the assessment of efficacy and so on;(4) can also be used without loss of information of interest to the region under the premise of image compression and transmission. This PACS, remote diagnostics, such as data transmission network is of great significance, can effectively improve network data transfer capacity.Research MethodsCase of patients with scoliosis before surgery for thoracic and lumbar CT scan, obtained Mimics 10.01 data into three-dimensional reconstruction software. In spinal reconstruction model based on the reconstruction of the lung and kidney.ResultsScoliosis in patients with the initial part of the establishment of three-dimensional model of internal organs, and the establishment of a preliminary finite element analysis mesh for analysis of individual organs in patients with preoperative and postoperative functional assessment of the preliminary work to make.ConclusionComputer applications in patients with scoliosis surgery simulation method has the feasibility of the design can be relatively intuitive, accurate reflection of the effect of orthopedic, surgical program for the development to provide a scientific basis.
