Kyphosis

 

curvature of the spine in man, with the convexity of the curve posterior.

The entire spine of the newborn is arced (total physiological kyphosis). As the infant develops, physiological kyphosis arises in the thoracic and sacral sections. Kyphosis in the thoracic spine may increase dramatically by old age because of developmental changes in the intervertebral disks and a weakening of muscle tone.

Pathological kyphosis, a result of congenital abnormalities in spine development (additional wedge-shaped vertebrae or the fusion of separate vertebrae), usually appears after the age of six months, once the infant has begun to stand and walk. Kyphosis can result from rickets, spinal tuberculosis, and certain familial conditions. It can also develop in persons who sit bent over for long periods of time because of occupation or myopia. Kyphosis is treated by special gymnastic exercises and by strengthening the back muscles by massage or physical therapy. Surgery may have to be performed if more conservative treatment proves unsuccessful.

kyphosis

[kī′fō·səs] (medicine) Angular curvature of the spine, usually in the thoracic region. Also known as humpback; hunchback.

Definition

Kyphosis is the extreme curvature of the upper back also known as a hunchback.

Description

The upper back bone (thoracic region), is normally curved forward. If the curve exceeds 50° it is considered abnormal (kyphotic).

Causes and symptoms

Kyphosis can be divided into three ages of acquisition—birth, old age, and the time in between.
  • Spinal birth defects can result in a fixed, exaggerated curve. Vertebrae can be fused together, shaped wrong, extraneous, or partially missing. Congenital and hereditary defects in bone growth weaken bone and result in exaggerated curves wherever gravity or muscles pull on them. Dwarfism is such a defect.
  • During life, several events can distort the spine. Because the natural tendency of the thoracic spine is to curve forward, any weakness of the supporting structures will tend in that direction. A diseased thoracic vertebra (a spine bone) will ordinarily crumble its forward edge first, increasing the kyphotic curve. Conditions that can do this include cancer, tuberculosis, Scheuermann's disease, and certain kinds of arthritis. Healthy vertebra will fracture forward with rapid deceleration injuries, such as in car crashes when the victim is not wearing a seat belt.
  • Later in life, kyphosis is caused from osteoporosis, bone weakness, and crumbling forward.
The stress caused by kyphosis produces such symptoms as an increase in musculoskeletal pains, tension headaches, back aches, and joint pains.

Diagnosis

A quick look at the back will usually identify kyphosis. X rays of the spine will confirm the diagnosis and identify its cause.

Treatment

Congenital defects have to be repaired surgically. The procedures are delicate, complicated, and lengthy. Often orthopedic hardware must be placed to stabilize the back bone. At other times, a device called a Milwaukee brace can hold the back in place from the outside. Fitting Milwaukee braces comfortably is difficult because they tend to rub and cause sores.Kyphosis acquired during the younger years requires treatment directed at the cause, such as medications for tuberculosis. Surgical reconstruction or bracing may also be necessary.Kyphosis induced by osteoporosis is generally not treated except to prevent further bone softening.

Prognosis

Congenital kyphosis may be alleviated to some extent by surgery and bracing. Kyphosis occurring later in life may worsen over time.

Prevention

Preventing osteoporosis is within the grasp of modern medicine. Menopausal women must start early with estrogen replacement, calcium supplementation, and appropriate exercise. The treatment must continue through the remainder of life. Evidence suggests that a high calcium intake even during younger years delays the onset of symptomatic osteoporosis. Dairy products are the major dietary sources of calcium.

kyphosis

 [ki-fo´sis] abnormally increased convex curvature of the thoracic spine as seen from the side; it may be the result of an acquired disease, an injury, or a congenital disorder or disease. It never develops from poor posture. One of the most common causes is postmenopausal osteoporosis accompanied by anterior vertebral body wedge-compression fractures. adj., adj kyphot´ic.
Kyphosis sometimes occurs with certain forms of poliomyelitis and with diseases that cause bone destruction, as happens in osteitis deformans (paget's disease). An injury, such as a fracture of the spine, treated improperly or not at all, may also result in hunchback. Some rare cases are caused by congenital deformities and diseases. One example, achondroplasia, or fetal rickets, is a congenital bone disorder that affects growth and bone formation. There are no specific symptoms besides back pain and increasing immobility of the spine. Symptoms vary with the cause, and any back pain or injury should be investigated.Kyphosis. From Frazier et al., 1996.

ky·pho·sis

(kī-fō'sis), 1. An anteriorly concave curvature of the vertebral column; the normal kyphoses of the thoracic and sacral regions are retained portions of the primary curvature (kyphosis) of the vertebral column. 2. A forward (flexion) curvature of the spine; the thoracic spine normally has a mild kyphosis; excessive forward curvature of the thoracic spine may indicate a pathologic condition. [G. kyphōsis, hump-back, fr. kyphos, bent, hump-backed]

kyphosis

(kī-fō′sĭs)n. Abnormal rearward curvature of the spine, resulting in protuberance of the upper back; hunchback.
ky·phot′ic (-fŏt′ĭk) adj.

kyphosis

Humpback, spinal kyphosis Orthopedics Angular curvature of the spine, with a posterior convexity, usually situated in the thoracic region involving a variable number of vertebrae Etiology TB, osteoarthrosis, rheumatoid arthritis, poor posture

ky·pho·sis

(kī-fō'sis) 1. An anteriorly concave curvature of the vertebral column, such as normally occurs in the thoracic and sacrococcygeal regions. 2. Hyperkyphosis; excessive anteriorly concave curvature of a part of the spine, usually thoracic.
Compare: hyperkyphotic
[G. kyphōsis, hump-back, fr. kyphos, bent, hump-backed]
KYPHOSIS

kyphosis

(ki-fo'sis) [Gr., humpback] 1. The normal posterior curvature of the thoracic and sacral spine.2. An exaggeration or angulation of the posterior curve of the thoracic spine, giving rise to the condition commonly known as humpback, hunchback, or Pott's curvature. It may be due to congenital anomaly, disease (tuberculosis, syphilis), malignancy, or compression fracture. This term also refers to an excessive curvature of the spine with convexity backward, which may result from osteoarthritis or rheumatoid arthritis, rickets, or other conditions. Synonym: humpback; spinal curvature See: illustrationkyphotic (-fot'ik), adjective

kyphosis

An abnormal degree of backward curvature of the part of the spine between the neck and the lumbar regions. Backward curvature is normal in this region and kyphosis is an exaggeration of the normal curve. It is commonly the result of bad postural habits in adolescence or of OSTEOPOROSIS. From the Greek kyphos , meaning bowed or bent.

ky·pho·sis

(kī-fō'sis) 1. An anteriorly concave curvature of the vertebral column; normal kyphoses of the thoracic and sacral regions are retained portions of the primary curvature of the vertebral column. 2. Forward curvature of spine. [G. kyphōsis, hump-back, fr. kyphos, bent, hump-backed]
