ankylosis

[ang′kilō′sis]

Etymology: Gk, ankylosis, bent condition

1 the fusion of a joint, often in an abnormal position, usually resulting from destruction of articular cartilage and subchondral bone, as occurs in rheumatoid arthritis. It may also occur in immobilized patients when active or passive range of motion is not provided. Also called true ankylosis. See also acampsia.

2 the surgically induced fusion of a joint to relieve pain or provide support. Also called arthrodesis, fusion. ankylosed, adj.

ankylosis (ang´kilō´sis),

n an abnormal fixation and immobility of a joint.

ankylosis, bony,

n a joining of bone with tooth or bone with bone that causes total loss of movement. See also tooth, ankylosed.

ankylosis, false,

n an inability to open the oral cavity because of trismus rather than disease of the joint.

ankylosis, fibrous,

n the fixation of a joint by fibrous tissue.

ankylosis of tooth,

n See tooth, ankylosed.

ankylosis

abnormal immobility and consolidation of a joint.

Ankylosis may be caused by destruction of the membranes that line the joint or by faulty bone structure. It is most often a result of chronic arthritis, in which the affected joint tends to assume the least painful position and may become more or less permanently fixed in it.

Artificial ankylosis (arthrodesis), locking of a joint by surgical operation, is sometimes done in treatment of a severe joint condition.

bony ankylosis

union of the bones of a joint by proliferation of bone cells, resulting in complete immobility.

extracapsular ankylosis

that caused by rigidity of surrounding parts.

false ankylosis, fibrous ankylosis

reduced joint mobility due to proliferation of fibrous tissue.

inherited multiple ankylosis

calves are affected at birth and cause fetal dystocia. The legs are bent and fixed in flexion, and there is some deformity of the spine. In one breed of cattle there is a combination of ankylosis and cleft palate.

intracapsular ankylosis

that caused by rigidity of structures within the joint.

spontaneous ankylosis

occurs in the intertarsal and tarsometatarsal joints of horses. Called also bone spavin.

spurious ankylosis

extracapsular ankylosis.

stapedial ankylosis

fixation of the footplate of the stapes in otosclerosis, causing a conductive hearing loss.

surgical ankylosis

performed to immobilize a painful joint or to correct excessive mobility, e.g. carpal ankylosis carried out on large birds as a deflighting procedure.

true ankylosis

bony ankylosis.

ankylosis

Orthopedics A fusion of bones across a joint, which may be a complication of chronic inflammation. See Ankylosing spondylitis.

Patient discussion about surgical ankylosis.

Q. Is ankylosing spondylitis genetically inherited?

A. It is known today that ankylosing spondylitis (spondyloarthritis) has a very strong genetic connection. It is not a disease inhertited by a single gene that is dominant, but certainly there is genetic predisposition in families (and a more detailed information- about 90% of the patients express the HLA-B27 genotype).

Q. I have had ankylosing spondilitis for over 25 years. What is available at this point to mitigate the effects?

A. The mainstay of the treatment severe ankylosing spondylitis today are "anti-TNF", drugs that affect the immune system through blocking the action of a protein called TNF.

Other optional treatments include sulfasalazine and thalidomide.
Of course, all these treatments require prescription and consultation with a doctor (in this case usually rheumatologist).
