| 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 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) |
| lunate dislocation | A wrist joint injury characterised by dislocation of the lunate. (27 Sep 1997) |
| apophysial fracture | Separation of apophysis from bone. (05 Mar 2000) |
| articular fracture | A fracture involving the joint surface of a bone. (05 Mar 2000) |
| atlas fracture | <radiology> Incidence: 4% of cervical spine injuries, site: posterior arch, anterior arch, massa lateralis, Jefferson fracture associated with: fractures of C7 (25%), fractures of C2 pedicle (15%), extraspinal fractures (58%) (12 Dec 1998) |
| avulsion fracture | A fracture that occurs when a joint capsule, ligament, or muscle insertion of origin is pulled from the bone as a result of a sprain dislocation or strong contracture of the muscle against resistance; as the soft tissue is pulled away from the bone, a fragment or fragments of the bone may come away with it. (05 Mar 2000) |
| axis fracture | <radiology> Incidence: 6% of cervical spine injuries, associated with atlas fractures in 8%, hyperflexion injury: odontoid fracture, type I avulsion of tip of odontoid (5-8%) difficult to detect, type II fracture through base of dens (54-67%) complication: nonunion, type III subdental injury (30-33%) prognosis: good, Differential diagnosis: os odontoideum, ossiculum terminale, hypoplasia/aplasia of dens, hyperextension injury: hangman's fracture (12 Dec 1998) |
