ankylosis /an·ky·lo·sis/ (ang″kĭ-lo´sis) pl. ankylo´ses [Gr.] immobility and consolidation of a joint due to disease, injury, or surgical procedure.ankylot´ic
artificial ankylosis arthrodesis. bony ankylosis union of the bones of a joint by proliferation of bone cells, resulting in complete immobility; true a. extracapsular ankylosis that due to rigidity of structures outside the joint capsule. false ankylosis fibrous a. fibrous ankylosis reduced joint mobility due to proliferation of fibrous tissue. intracapsular ankylosis that due to disease, injury, or surgery within the joint capsule.
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″kĭ-lo´sis] (pl. ankylo´ses) (Gr.) immobility and consolidation of a joint due to disease, injury, or surgical procedure. adj., adj ankylot´ic. 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 rheumatoid arthritis, in which the affected joint tends to assume the least painful position and may become more or less permanently fixed in it. Other causes include infection and traumatic injury to the joint. Artificial ankylosis (arthrodesis), fusion of a joint by surgical operation, is sometimes done to ameliorate the pain experienced in a severe joint condition. bony ankylosis union of the bones of a joint by loss of articular cartilage, 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. intracapsular ankylosis that caused by rigidity of structures within the joint. spurious ankylosis extracapsular ankylosis. stapedial ankylosis fixation of the footplate of the stapes in otosclerosis, causing conductive hearing loss. true ankylosis bony ankylosis.
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 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.

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