Term
closed fracture
Definition
Fracture in which there is no open skin wound.  Also called a simple fracture.
Term
Colles' fracture
Definition
A common type of wrist fracture.
Term
comminuted fracture
Definition
Fracture in which the bone is shattered, slplintered, or crushed into many small pieces or fragments.
Term
compound fracture
Definition
Fracture in which the skin has been broken through to the fracture.  Also called an open fracture.
Term
compression fracture
Definition
Fracture involving loss of height of a vertebral body.  It may be the result of trauma, but in older persons, especially women, it may be caused by conditions like osteoporosis.
Term
fracture (FX, Fx)
Definition
A broken bone.
Term
greenstick fracture
Definition
Fracture in which there is an incomplete break; one side of bone is broken and the other side is bent.  This type of fracture is commonly found in children dus to their softer and more pliable bone structure.
Term
impacted fracture
Definition
Fracture in which bone fragments are pushed into each other.
Term
oblique fracture
Definition
Fracture at an angle to the bone.
Term
pathologic fracture
Definition
Fracture caused by diseased or weakend bone.
Term
spiral fracture
Definition
Fracture in which the fracture line spirals around the shaft of the bone.  Can be caused by a twisting injury and is often slower to heal than other types of fractures.
Term
stress fracture
Definition
A slight fracture caused by repetitive low-impact forces, like running, rather than a single forceful impact.
Term
transverse fracture
Definition
Complete fracture that is straight across the bone at right angles to the long axis of the bone.
Term
Ewing's sarcoma
Definition
Malignant growth found in the shaft of long bones that spreads through the periosteum.  Removal is treatment of choice, because this tumor will metastasize or spread to other organs.
Term
osteogenic sarcoma
Definition
The most common type of bone cancer.  Usually begins in osteocytes found at the ends of long bones.
Term
osteomalacia
Definition
Softening of the bones caused by a deficiency of calcium.  It is thought that in children the cause is insufficient sunlight and vitamin D.
Term
osteoporosis
Definition
Decrease in bone mass that results in a thinning and weakening of the bone with resulting fractures.  The bone becomes more porous, especially in the spine and pelvis.
Term
Paget's disease
Definition
A fairly common metabolic disease of the bone from unknown causes.  It usually attacks middle-aged and elderly people and is characterized by bone destruction and deformity.  Named for Sir James Paget, a British surgeon.
Term
rickets
Definition
Deficiency in calcium and vitamin D found in early childhood that results in bone deformities, especially bowed legs.
Term
ankylosing spondylitis
Definition
Inflammatory spinal condition that resembles rheumatoid arthritis.  Results in gradual stiffening and fusion of the vertebrea.  More common in men than women.
Term
herniated necleus pulposus (HNP)
Definition
Herniation or protrusion of an intervertebral disk; also called herniated disk or ruptured disk.  May require surgery.
Term
scoliosis
Definition
Abnormal lateral curvature of the spine. 
Term
spina bifida
Definition
Congenital anomaly that occurs when a vertebra fails to fully form around the spinal cord.
Term
spinal stenosis
Definition
Narrowing of the spinal canal causing pressure on the cord and nerves.
Term
spondylolisthesis
Definition
The forward sliding of a lumbar vertebra over the vertebra below it.
Term
spondylosis
Definition
Specifically refers to ankylosing of the spine, but commonly used in reference to any degenerative condition of the vertebral column.
Term
whiplash
Definition
Injury to the bones in the cervical spine as a result of a sudden movement forward and backward of the head and neck.  Can occur as a result of a rearend collision.
Term
bunion
Definition
Inflammation of the bursa of the first metatarsophalangeal joint (base of the big toe).
Term
dislocation
Definition
Occurs when the bones in a joint are displaced from their normal alignment and the ends of the bones are no longer in contact.
Term
osteoarthritis
Definition
Arthritis resulting in degeneration of the bones and joints, especially those bearing weight.  Results in bone rubbing against bone.
Term
rheumatoid arthritis (RA)
Definition
Chronic form of arthritis with inflammation of the joints, swelling, stiffness, pain, and changes in the cartilage that can result in crippling deformities; considered to be an autoimmune disease.
Term
sprain
Definition
Damage to the ligaments surrounding a joing due to overstretching, but no dislocation of the joint or fracture of the bone.
Term
systemic lupus erythematosus (SLE)
Definition
Chronic inflammatory autoimmune disease of connective tissue affects many systems that may include joint pain and arthritis.  May be mistaken for rheumatoid arthritis.
Term
talipes
Definition
Congenital deformity causing misalignment of the ankle joint and foot.  Also refferred to as a clubfoot.
