| fractures | Breaks in bones or cartilage. (12 Dec 1998) |
|---|---|
| fractures, closed | Fractures in which the break in bone is not accompanied by an external wound. (12 Dec 1998) |
| fractures, comminuted | A fracture in which the bone is splintered or crushed. (12 Dec 1998) |
| fractures, malunited | Union of the fragments of a fractured bone in a faulty or abnormal position. If two bones parallel to one another unite by osseous tissue, the result is a crossunion. (12 Dec 1998) |
| fractures, open | Fractures in which there is an external wound communicating with the break of the bone. (12 Dec 1998) |
| fractures, spontaneous | Fractures occurring as a result of disease of a bone or from some undiscoverable cause, and not due to trauma. (12 Dec 1998) |
| fractures, stress | 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 classical stress fracture is the march fracture of military personnel, in which the metatarsal undergoes repeated stress during marching. The most common sites of stress fractures are the metatarsus, fibula, tibia, and femoral neck. (12 Dec 1998) |
| fractures, ununited | A fracture in which union fails to occur, the ends of the bone becoming rounded and eburnated, and a false joint occurs. (12 Dec 1998) |
| alar spine | A posterior and downward projection from the greater wing of the sphenoid bone on either side, located posterolateral to the foramen spinosum, so-named for its proximity to the sphenoidal spine; gives attachment to the sphenomandibular ligament. Synonym: processus spinosus, spina ossis sphenoidalis, alar spine, angular spine, spina angularis, spinous process. (05 Mar 2000) |

Synonym: processus spinosus, spina ossis sphenoidalis, alar spine, angular spine, spina angularis, spinous process. (05 Mar 2000) |
| anterior inferior iliac spine | Spine on the anterior border of the ilium between the anterior superior iliac spine and the acetabulum; site of origin for the direct head of the rectus femoris muscle. Synonym: spina iliaca anterior inferior. (05 Mar 2000) |
| anterior nasal spine | A pointed projection at the anterior extremity of the intermaxillary suture; the tip, as seen on a lateral cephalometric radiograph, is used as a cephalometric landmark. Synonym: spina nasalis anterior. (05 Mar 2000) |
| anterior superior iliac spine | The anterior extremity of the iliac crest, which provides attachment for the inguinal ligament and the sartorius muscle. Synonym: spina iliaca anterior superior. (05 Mar 2000) |
| bamboo spine | In radiology, the appearance of the thoracic or lumbar spine with ankylosing spondylitis. (05 Mar 2000) |
| meatal spine | Small bony prominence anterior to the supramastoid pit at the posterosuperior margin of the bony external acoustic meatus. Synonym: spina suprameatica, Henle's spine, meatal spine, spina meatus. (05 Mar 2000) |
