Computer Assisted Surgery
Computer-assisted surgery (CAS) represents a surgical concept and set of methods, that use computer technology for surgical planning, and for guiding or performing surgical interventions. CAS is also known as computer-aided surgery, computer-assisted intervention, image-guided surgery, digital surgery and surgical navigation, but these are terms that are more or less synonymous with CAS. CAS has been a leading factor in the development of robotic surgery. General principles Creating a virtual image of the patient The most important component for CAS is the development of an accurate model of the patient. This can be conducted through a number of medical imaging technologies including Computed tomography, CT, MRI, x-rays, ultrasound plus many more. For the generation of this model, the anatomical region to be operated has to be scanned and uploaded into the computer system. It is possible to employ a number of scanning methods, with the datasets combined through data fusion ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surgical Planning
Surgery is a medical specialty that uses manual and instrumental techniques to diagnose or treat pathological conditions (e.g., trauma, disease, injury, malignancy), to alter bodily functions (e.g., malabsorption created by bariatric surgery such as gastric bypass), to reconstruct or alter aesthetics and appearance ( cosmetic surgery), or to remove unwanted tissues (body fat, glands, scars or skin tags) or foreign bodies. The act of performing surgery may be called a surgical procedure or surgical operation, or simply "surgery" or "operation". In this context, the verb "operate" means to perform surgery. The adjective surgical means pertaining to surgery; e.g. surgical instruments, surgical facility or surgical nurse. Most surgical procedures are performed by a pair of operators: a surgeon who is the main operator performing the surgery, and a surgical assistant who provides in-procedure manual assistance during surgery. Modern surgical operations typically require a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bone Malrotation
A bone is a rigid organ that constitutes part of the skeleton in most vertebrate animals. Bones protect the various other organs of the body, produce red and white blood cells, store minerals, provide structure and support for the body, and enable mobility. Bones come in a variety of shapes and sizes and have complex internal and external structures. They are lightweight yet strong and hard and serve multiple functions. Bone tissue (osseous tissue), which is also called bone in the uncountable sense of that word, is hard tissue, a type of specialised connective tissue. It has a honeycomb-like matrix internally, which helps to give the bone rigidity. Bone tissue is made up of different types of bone cells. Osteoblasts and osteocytes are involved in the formation and mineralisation of bone; osteoclasts are involved in the resorption of bone tissue. Modified (flattened) osteoblasts become the lining cells that form a protective layer on the bone surface. The mineralised ...

Osteosynthesis
Internal fixation is an operation in orthopedics that involves the surgical implementation of implants for the purpose of repairing a bone, a concept that dates to the mid-nineteenth century and was made applicable for routine treatment in the mid-twentieth century. An internal fixator may be made of stainless steel, titanium alloy, or cobalt-chrome alloy. Types of internal fixators include: * Plate and screws * Kirschner wires * Intramedullary nails Open reduction Open reduction internal fixation (ORIF) involves the implementation of implants to guide the healing process of a bone, as well as the open reduction, or setting, of the bone. ''Open reduction'' refers to open surgery to set bones, as is necessary for some fractures. ''Internal fixation'' refers to fixation of screws and/or plates, intramedullary rods and other devices to enable or facilitate healing. Rigid fixation prevents micro-motion across lines of fracture to enable healing and prevent infection, which hap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pedicle Of Vertebral Arch
Each vertebra (: vertebrae) is an irregular bone with a complex structure composed of bone and some hyaline cartilage, that make up the vertebral column or spine, of vertebrates. The proportions of the vertebrae differ according to their spinal segment and the particular species. The basic configuration of a vertebra varies; the vertebral body (also ''centrum'') is of bone and bears the load of the vertebral column. The upper and lower surfaces of the vertebra body give attachment to the intervertebral discs. The posterior part of a vertebra forms a vertebral arch, in eleven parts, consisting of two pedicles (pedicle of vertebral arch), two laminae, and seven processes. The laminae give attachment to the ligamenta flava (ligaments of the spine). There are vertebral notches formed from the shape of the pedicles, which form the intervertebral foramina when the vertebrae articulate. These foramina are the entry and exit conduits for the spinal nerves. The body of the vertebra a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hip Replacement
Hip replacement is a surgery, surgical procedure in which the hip joint is replaced by a prosthetic implant (medicine), implant, that is, a hip prosthesis. Hip replacement surgery can be performed as a total replacement or a hemi/semi(half) replacement. Such joint replacement orthopaedic surgery is generally conducted to relieve arthritis pain or in some hip fractures. A total hip replacement (total hip arthroplasty) consists of replacing both the acetabulum and the femoral head while hemiarthroplasty generally only replaces the femoral head. Hip replacement is one of the most common orthopaedic operations, though patient satisfaction varies widely between different techniques and implants. Approximately 58% of total hip replacements are estimated to last 25 years. The average cost of a total hip replacement in 2012 was $40,364 in the United States (€37,307.44 in euros), and about $7,700 to $12,000 in most European countries. NOTE: In euros, that is from €7,116.92 to €11,091 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Orthognathic Surgery
Orthognathic surgery (), also known as corrective jaw surgery or simply jaw surgery, is surgery designed to correct conditions of the jaw and lower face related to structure, growth, airway issues including sleep apnea, TMJ disorders, malocclusion problems primarily arising from skeletal disharmonies, and other orthodontic dental bite problems that cannot be treated easily with braces, as well as the broad range of facial imbalances, disharmonies, asymmetries, and malproportions where correction may be considered to improve facial aesthetics and self-esteem. The origins of orthognathic surgery belong in oral surgery, and the basic operations related to the surgical removal of impacted or displaced teeth – especially where indicated by orthodontics to enhance dental treatments of malocclusion and dental crowding. One of the first published cases of orthognathic surgery was the one from Dr. Simon P. Hullihen in 1849. Originally coined by Harold Hargis, it was more widely popul ...

Bone Segment Navigation
Bone segment navigation is a surgical method used to find the anatomical position of displaced bone fragments in fractures, or to position surgically created fragments in craniofacial surgery. Such fragments are later fixed in position by osteosynthesis. It has been developed for use in craniofacial and oral and maxillofacial surgery. Bone segment navigation is a patented surgical procedure, using a frameless and markerless registration technique. It uses for the first time natural registration surfaces instead of single artificial x-ray visible markers, in order to achieve a higher precision (1 mm and better). Previous methods of Cutting and Watzinger do not meet the criteria of bone segment navigation. After an accident or injury, a fracture can be produced and the resulting bony fragments can be displaced. In the oral and maxillofacial area, such a displacement could have a major effect both on facial aesthetics and organ function: a fracture occurring in a bone that delimits ...
