Osteotomy, Le Fort
Transverse sectioning and repositioning of the maxilla. There are three types: Le Fort I osteotomy for maxillary advancement or the treatment of maxillary fractures; Le Fort II osteotomy for the treatment of maxillary fractures; Le Fort III osteotomy for the treatment of maxillary fractures with fracture of one or more facial bones. Le Fort III is often used also to correct craniofacial dysostosis and related facial abnormalities. (From Dorland, 28th ed, p1203 & p662)
Joint Deformities, Acquired
Hip Dislocation, Congenital
Congenital dislocation of the hip generally includes subluxation of the femoral head, acetabular dysplasia, and complete dislocation of the femoral head from the true acetabulum. This condition occurs in approximately 1 in 1000 live births and is more common in females than in males.
Osteotomy, Sagittal Split Ramus
Sagittal sectioning and repositioning of the ramus of the MANDIBLE to correct a mandibular retrusion, MALOCCLUSION, ANGLE CLASS III; and PROGNATHISM. The oblique sectioning line consists of multiple cuts horizontal and vertical to the mandibular ramus.
A particular type of FEMUR HEAD NECROSIS occurring in children, mainly male, with a course of four years or so.
Range of Motion, Articular
Jaw Fixation Techniques
The stable placement of surgically induced fractures of the mandible or maxilla through the use of elastics, wire ligatures, arch bars, or other splints. It is used often in the cosmetic surgery of retrognathism and prognathism. (From Dorland, 28th ed, p636)
The physiological restoration of bone tissue and function after a fracture. It includes BONY CALLUS formation and normal replacement of bone tissue.
Femur Head Necrosis
Aseptic or avascular necrosis of the femoral head. The major types are idiopathic (primary), as a complication of fractures or dislocations, and LEGG-CALVE-PERTHES DISEASE.
Leg Length Inequality
The articulation between a metatarsal bone (METATARSAL BONES) and a phalanx.
The bone of the lower leg lateral to and smaller than the tibia. In proportion to its length, it is the most slender of the long bones.
Steel wires, often threaded through the skin, soft tissues, and bone, used to fix broken bones. Kirschner wires or apparatus also includes the application of traction to the healing bones through the wires.
Fracture Fixation, Internal
Noninflammatory degenerative disease of the knee joint consisting of three large categories: conditions that block normal synchronous movement, conditions that produce abnormal pathways of motion, and conditions that cause stress concentration resulting in changes to articular cartilage. (Crenshaw, Campbell's Operative Orthopaedics, 8th ed, p2019)
Recovery of Function
Orthognathic Surgical Procedures
Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
A bone fixation technique using an external fixator (FIXATORS, EXTERNAL) for lengthening limbs, correcting pseudarthroses and other deformities, and assisting the healing of otherwise hopeless traumatic or pathological fractures and infections, such as chronic osteomyelitis. The method was devised by the Russian orthopedic surgeon Gavriil Abramovich Ilizarov (1921-1992). (From Bull Hosp Jt Dis 1992 Summer;52(1):1)
Bone in humans and primates extending from the SHOULDER JOINT to the ELBOW JOINT.
The outer shorter of the two bones of the FOREARM, lying parallel to the ULNA and partially revolving around it.
Fractures of the femur.
Foot Deformities, Acquired
Orthopedic Fixation Devices
The physical state of supporting an applied load. This often refers to the weight-bearing bones or joints that support the body's weight, especially those in the spine, hip, knee, and foot.
The pull on a limb or a part thereof. Skin traction (indirect traction) is applied by using a bandage to pull on the skin and fascia where light traction is required. Skeletal traction (direct traction), however, uses pins or wires inserted through bone and is attached to weights, pulleys, and ropes.
