Ewing sarcoma
Malignant bone tumor occurring in children. Rare malignant tumor arising in bone; most often occurring in children.
exostosis
Bony growth arising from the surface of a bone.
bunion
Abnormal swelling of the joint between the big toe and the bone of the foot. A swelling of the metatarsophalangeal joint near the base of the big toe and is accompanied by the buildup of soft tissue and underlying bone at the distal/medial aspect of the first metatarsal.
fracture
Traumatic breaking of a bone.
simple fracture (closed)
The bone is broken but there is no open would in the skin.
compound fracture (open)
The bone is broken and a fragment of bone protrudes through an open wound in the skin.
Colles fracture (wrist)
Near the wrist at distal end of the radius.
comminuted fracture
Bone is splintered and crushed into several pieces.
compression fracture
Bone collapses or is compressed; occurs in vertebrae.
greenstick fracture
Bone is partially broken; breaks on one surface and bends on another; often occurring in forearm.
Impacted fracture
One fragment is driven firmly into the other fragment; at the head of the femur or head of the humerus.
osteogenic sarcoma (osteosarcoma)
Malignant (cancerous) tumor of bone tissue.
osteomalacia
Softening of bones with inadequate amounts of mineral (calcium) in the bone.
osteomyelitis
Inflammation of the bone and bone marrow secondary to infection.
osteoporosis
Decrease in bone density (mass); thinning and weakening of bone. Bones become thin, weak, brittle, and break easily.
