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)

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.

The longest and largest bone of the skeleton, it is situated between the hip and the knee.

The five long bones of the METATARSUS, articulating with the TARSAL BONES proximally and the PHALANGES OF TOES distally.

The part of the pelvis that comprises the pelvic socket where the head of FEMUR joins to form HIP JOINT (acetabulofemoral joint).

Bones that constitute each half of the pelvic girdle in VERTEBRATES, formed by fusion of the ILIUM; ISCHIUM; and PUBIC BONE.

A particular type of FEMUR HEAD NECROSIS occurring in children, mainly male, with a course of four years or so.

The joint that is formed by the articulation of the head of FEMUR and the ACETABULUM of the PELVIS.

Implantable fracture fixation devices attached to bone fragments with screws to bridge the fracture gap and shield the fracture site from stress as bone heals. (UMDNS, 1999)

The distance and direction to which a bone joint can be extended. Range of motion is a function of the condition of the joints, muscles, and connective tissues involved. Joint flexibility can be improved through appropriate MUSCLE STRETCHING EXERCISES.

Displacement of the femur bone from its normal position at the HIP JOINT.

Surgery of the upper jaw bone usually performed to correct upper and lower jaw misalignment.

Increase in the longest dimension of a bone to correct anatomical deficiencies, congenital, traumatic, or as a result of disease. The lengthening is not restricted to long bones. The usual surgical methods are internal fixation and distraction.

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)

Displacement of bones out of line in relation to joints. It may be congenital or traumatic in origin.

Developmental bone diseases are a category of skeletal disorders that arise from disturbances in the normal growth and development of bones, including abnormalities in size, shape, structure, or composition, which can lead to various musculoskeletal impairments and deformities.

The part of the foot between the tarsa and the TOES.

Deformities of the SPINE characterized by an exaggerated convexity of the vertebral column. The forward bending of the thoracic region usually is more than 40 degrees. This deformity sometimes is called round back or hunchback.

The inner and longer bone of the FOREARM.

Surgical reconstruction of a joint to relieve pain or restore motion.

The hemispheric articular surface at the upper extremity of the thigh bone. (Stedman, 26th ed)

The physiological restoration of bone tissue and function after a fracture. It includes BONY CALLUS formation and normal replacement of bone tissue.

Evaluation undertaken to assess the results or consequences of management and procedures used in combating disease in order to determine the efficacy, effectiveness, safety, and practicability of these interventions in individual cases or series.

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.

A condition in which one of a pair of legs fails to grow as long as the other, which could result from injury or surgery.

Noninflammatory degenerative disease of the hip joint which usually appears in late middle or old age. It is characterized by growth or maturational disturbances in the femoral neck and head, as well as acetabular dysplasia. A dominant symptom is pain on weight-bearing or motion.

Specialized devices used in ORTHOPEDIC SURGERY to repair bone fractures.

A synovial hinge connection formed between the bones of the FEMUR; TIBIA; and PATELLA.

Internal devices used in osteosynthesis to hold the position of the fracture in proper alignment. By applying the principles of biomedical engineering, the surgeon uses metal plates, nails, rods, etc., for the correction of skeletal defects.

External devices which hold wires or pins that are placed through one or both cortices of bone in order to hold the position of a fracture in proper alignment. These devices allow easy access to wounds, adjustment during the course of healing, and more functional use of the limbs involved.

Slipped epiphyses is a medical condition where the growth plate (epiphyseal plate) at the end of long bones in children and adolescents becomes injured or dislocated, often affecting the hip area, and potentially causing pain, walking difficulties, and limping.

A repeat operation for the same condition in the same patient due to disease progression or recurrence, or as followup to failed previous surgery.

The use of HIGH-ENERGY SHOCK WAVES, in the frequency range of 20-30 kHz, to cut through mineralized tissue.

Pathologic processes that affect patients after a surgical procedure. They may or may not be related to the disease for which the surgery was done, and they may or may not be direct results of the surgery.

The articulation between a metatarsal bone (METATARSAL BONES) and a phalanx.

Studies in which individuals or populations are followed to assess the outcome of exposures, procedures, or effects of a characteristic, e.g., occurrence of disease.

Lack of stability of a joint or joint prosthesis. Factors involved are intra-articular disease and integrity of extra-articular structures such as joint capsule, ligaments, and muscles.

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.

The seven bones which form the tarsus - namely, CALCANEUS; TALUS; cuboid, navicular, and the internal, middle, and external cuneiforms.
