A fracture in which union fails to occur, the ends of the bone becoming rounded and eburnated, and a false joint occurs. (Stedman, 25th ed)
The use of internal devices (metal plates, nails, rods, etc.) to hold the position of a fracture in proper alignment.
Breaks in bones.
The physiological restoration of bone tissue and function after a fracture. It includes BONY CALLUS formation and normal replacement of bone tissue.
Fractures of the FEMUR HEAD; the FEMUR NECK; (FEMORAL NECK FRACTURES); the trochanters; or the inter- or subtrochanteric region. Excludes fractures of the acetabulum and fractures of the femoral shaft below the subtrochanteric region (FEMORAL FRACTURES).
Fractures of the femur.
Broken bones in the vertebral column.
A fracture in which the bone is splintered or crushed. (Dorland, 27th ed)
The use of metallic devices inserted into or through bone to hold a fracture in a set position and alignment while it heals.
Breaks in bones resulting from low bone mass and microarchitectural deterioration characteristic of OSTEOPOROSIS.
Fractures occurring as a result of disease of a bone or from some undiscoverable cause, and not due to trauma. (Dorland, 27th ed)
Fractures due to the strain caused by repetitive exercise. They are thought to arise from a combination of MUSCLE FATIGUE and bone failure, and occur in situations where BONE REMODELING predominates over repair. The most common sites of stress fractures are the METATARSUS; FIBULA; TIBIA; and FEMORAL NECK.
Fractures of the short, constricted portion of the thigh bone between the femur head and the trochanters. It excludes intertrochanteric fractures which are HIP FRACTURES.
Fractures of the larger bone of the forearm.
The use of nails that are inserted into bone cavities in order to keep fractured bones together.
Fractures of the skull which may result from penetrating or nonpenetrating head injuries or rarely BONE DISEASES (see also FRACTURES, SPONTANEOUS). Skull fractures may be classified by location (e.g., SKULL FRACTURE, BASILAR), radiographic appearance (e.g., linear), or based upon cranial integrity (e.g., SKULL FRACTURE, DEPRESSED).
Fractures of the lower jaw.
Break or rupture of a tooth or tooth root.
Crumbling or smashing of cancellous BONE by forces acting parallel to the long axis of bone. It is applied particularly to vertebral body fractures (SPINAL FRACTURES). (Blauvelt and Nelson, A Manual of Orthopedic Terminology, 1994, p4)
Fractures of the articular surface of a bone.
Reduction of bone mass without alteration in the composition of bone, leading to fractures. Primary osteoporosis can be of two major types: postmenopausal osteoporosis (OSTEOPOROSIS, POSTMENOPAUSAL) and age-related or senile osteoporosis.
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)
Rods of bone, metal, or other material used for fixation of the fragments or ends of fractured bones.
Fractures of the bones in the orbit, which include parts of the frontal, ethmoidal, lacrimal, and sphenoid bones and the maxilla and zygoma.
Fracture of the lower end of the radius in which the lower fragment is displaced posteriorly.
The bony deposit formed between and around the broken ends of BONE FRACTURES during normal healing.
Fractures around joint replacement prosthetics or implants. They can occur intraoperatively or postoperatively.
The amount of mineral per square centimeter of BONE. This is the definition used in clinical practice. Actual bone density would be expressed in grams per milliliter. It is most frequently measured by X-RAY ABSORPTIOMETRY or TOMOGRAPHY, X RAY COMPUTED. Bone density is an important predictor for OSTEOPOROSIS.
Educational institutions.
Analog or digital communications device in which the user has a wireless connection from a telephone to a nearby transmitter. It is termed cellular because the service area is divided into multiple "cells." As the user moves from one cell area to another, the call is transferred to the local transmitter.
Institutions specializing in the care of cancer patients.
Educational institutions for individuals specializing in the field of medicine.
Professionals qualified by graduation from an accredited school of nursing and by passage of a national licensing examination to practice nursing. They provide services to patients requiring assistance in recovering or maintaining their physical or mental health.
Time period from 1901 through 2000 of the common era.
A thick, fibrocartilaginous ligament at the metacarpophalageal joint.
Sports performed on a track, field, or arena and including running events and other competitions, such as the pole vault, shot put, etc.
The grafting of bone from a donor site to a recipient site.
A partial joint replacement in which only one surface of the joint is replaced with a PROSTHESIS.
A specialized CONNECTIVE TISSUE that is the main constituent of the SKELETON. The principle cellular component of bone is comprised of OSTEOBLASTS; OSTEOCYTES; and OSTEOCLASTS, while FIBRILLAR COLLAGENS and hydroxyapatite crystals form the BONE MATRIX.
