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/.

Term:Corner fracture of metaphysis

Accession:HP:0003908 term browser browse the term
Definition:Fracture or fragmentation at the lateral portion of the metaphysis of a long bone. The radiographic appearance is that of a small corner of metaphysis separated from the metaphyseal edge by thin linear radiolucency. This feature can be observed in child abuse but fragmented appearance of the metaphysis or facture-like lesions can also be detected in the setting of certain skeletal dysplasias.
Comment:A corner fracture is a subepiphyseal planer fracture through immature metaphyseal bone. The appearance of a corner, avulsion or bucket handle depends on the extent of bone failure and radiographic projection. Bone can fail in this pattern from both shearing and tensile stresses. The weakest area of bone for a given loading condition determines the injury threshold for that structure.
Synonyms:exact_synonym: Bucket handle fracture;   Metaphyseal corner fracture
