| wedge-and-groove joint | A form of fibrous joint in which the sharp edge of one bone is received in a cleft in the edge of the other, as in the articulation of the vomer with the rostrum of the sphenoid. Synonym: schindylesis, schindyletic joint, wedge-and-groove suture. (05 Mar 2000) |
| pisotriquetral joint | The synovial joint between the pisiform and triquetrum; it is separate from the other intercarpal joints. Synonym: articulatio ossis pisiformis, articulation of pisiform bone. (05 Mar 2000) |
| pivot joint | A synovial joint in which a section of a cylinder of one bone fits into a corresponding cavity on the other, as in the proximal radioulnar joint.
