| hip dislocation, congenital | Congenital dislocation of the hip generally includes subluxation of the femoral head, acetabular dysplasia, and complete dislocation of the femoral head from the true acetabulum. This condition occurs in approximately 1 in 1000 live births and is more common in females than in males. (12 Dec 1998) |

| shoulder dislocation | <radiology> Anterior (subcoracoid), humerus may lead to beneath coracoid process, anterior to glenoid, most frequent site and type of dislocation of any joint, easily detected, repeated dislocation most likely to be Hill-Sachs deformity and/or Bankhart deformity, posterior, 2 - 4% of shoulder dislocations, 50% due to seizures; trauma, electrical shock, often missed on AP view: use Y or axillary view, rim sign in acute dislocation, increased glenohumeral space (normal 6 mm may lead to widened to 14 mm), with or without compression fracture of anterior surface of humeral head, 20% most likely to be associated fracture (12 Dec 1998) |
| simple dislocation | A dislocation not complicated by an external wound. Synonym: simple dislocation. (05 Mar 2000) |
| Nelaton's dislocation | Wedging of the astragalus between the widely separated tibia and fibula, usually complicated with fracture. (05 Mar 2000) |
| dequervain dislocation | <radiology> Transscaphoid lunate dissociation (12 Dec 1998) |
| desault dislocation | <radiology> Volar displacent of a dislocation of the distal radius (12 Dec 1998) |
| dislocation | <orthopaedics> The displacement of any part, more especially of a bone. Synonym: luxation. Origin: L. Locare = to place (18 Nov 1997) |
| dislocation fracture | A fracture of a bone near an articulation with its concomitant dislocation from that joint. (05 Mar 2000) |
| dislocation of articular processes | Complete dislocation of one or both articular processes, usually with overriding of the inferior articular process of the vertebra above into a position anterior to the superior articular process of the vertebra below. Synonym: locked facets. (05 Mar 2000) |
| dislocation of lens | Congenital displacement of the lens resulting from defective zonule formation. (12 Dec 1998) |
| open dislocation | A dislocation complicated by a wound opening from the surface down to the affected joint. Synonym: compound dislocation. (05 Mar 2000) |
| Kienbock's dislocation | Dislocation of semilunar bone. (05 Mar 2000) |
| knee cap dislocation | <orthopaedics> A dislocation of the knee cap most often occurs with the knee cap moving laterally (toward the outer aspect of the leg). Features include a partially flexed knee joint with obvious displacement of the knee cap laterally. Reduction is accomplished with knee joint extension and gently coaxing the knee cap back to the midline. (17 Dec 1997) |
| fracture dislocation | Dislocation associated with or accompanied by a fracture. (05 Mar 2000) |
| lisfranc fracture-dislocation | <radiology> Tarsal-metatarsal fracture-dislocation, trauma, diabetes (neuropathic) (12 Dec 1998) |
