HUMAN PHENOTYPE - ANNOTATIONS

The Human Phenotype Ontology (HPO) is downloaded weekly from http://compbio.charite.de/hudson/job/hpo/lastStableBuild/artifact/ontology/release/hp.obo. The file downloaded is considered the "last stable build" available for the ontology. For more about the HPO, view their website at http://www.human-phenotype-ontology.org/.

Definition:An anomaly of the sacroiliac joint, which connects the base of the spine (sacrum) to the ilium (a hip bone).
Comment:The sacroiliac joint (SIJ) is a true diarthrodial joint: matching articular surfaces separated by a joint space containing synovial fluid and enveloped by a fibrous capsule. It does, however, have unique characteristics not typically found in other diarthrodial joints. The SIJ has fibrocartilage in addition to hyaline cartilage. There is discontinuity of the posterior capsule. Rather than being smooth, the articular surfaces have many ridges and depressions that minimize movement and enhance stability. Primary stability, however, is attributed to the many adjacent ligaments.
Synonyms:exact_synonym: Abnormality of the sacroiliac joint
