| patellar dislocation | <radiology> most common in young girls, (genu valgum, patella alta, quad mm deficiency more in girls), lateral dislocation, spontaneous reduction, recurrent dislocation, fracture associated in 5-10% (12 Dec 1998) |
|---|---|
| perilunar dislocation | Dislocation of carpal bones around the lunate, which remains in relation to the radius; distinguish from dislocation of lunate, Kienbock's dislocation. (05 Mar 2000) |
| perilunate dislocation | <radiology> Lunate remains aligned with radius, capitate dislocates (usually posteriorly), more common than lunate dislocation (radial-lunate ligaments stronger than lunate-capitate ligaments), associated with scaphoid fractures (75%) = transscaphoid perilunate dislocation (12 Dec 1998) |
| chopart fracture-dislocation | <radiology> A fracture-dislocation occuring through the hindfoot-midfoot joint (i.e., tarsonavicular and calcaneocuboid joints) (12 Dec 1998) |
| closed dislocation | A dislocation not complicated by an external wound. Synonym: simple dislocation. (05 Mar 2000) |
| compound dislocation | Synonym: open dislocation. (05 Mar 2000) |
| congenital hip dislocation | A malformation of the hip joint that is present at birth. Genetic factors likely play a role in this disorder. Features include hip dislocation, asymmetry of leg positions, asymmetric fat folds and diminished movement on the affected side. Some children will exhibit little or no features and must be diagnosed by physical examination of the hip joints. (27 Sep 1997) |
| wrist dislocation | <radiology> 10% of all carpal injuries due to fall on outstretched hand, perilunate dislocation (more common), lunate dislocation (12 Dec 1998) |
| hip dislocation | <radiology> Usually posterior, hip flexed, knee hits dashboard during deceleration, superior migration of femoral head, with or without acetabular fracture (12 Dec 1998) |
| 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) |
| 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) |
