Magnetic resonance imaging after reduction for congenital dislocation of the hip

Abstract

In view of the number of inadequate reductions in plaster casts, we recommend verifying the position of the hip joint by MRI. This MRI documentation should be established as a standard examination post-reduction.

Determination of hip reduction in spica cast treatment for DDH: A comparison of radiography and ultrasound

“…MRI, a diagnostic tool that does not necessitate exposure to radiation, gives an excellent overview of anatomical structures of infant hips [5,12]. The accuracy with which it can determine hip reduction is clearly demonstrated in the literature [5,8,12,13]. However, MRI is expensive and, like CT, not usually immediately available in the operating room.…”

“…CT results in a high radiation exposure. Therefore, others have recommended MRI as the imaging method of choice [5][6][7][8]. However, MRI is not immediately available in the operating room.…”

MRI assessment of DDH after reduction

“…Attention should be given to contrast medium concentration and to avoid extravasation or causing damage to vasomotor nerves during needle placement 6 . The radiation load should be considered when requesting CT 1,7,8 . Although MRI is not regularly used in DDH, its indications are increasing.…”

Utility of magnetic resonance imaging (MRI) after closed reduction of developmental dysplasia of the hip

“…MRI is a superior soft-tissue contrast resolution which allows differentiation between articular structures such as bone, hyaline and fibrous cartilage, ligaments, joint capsule, intra-articular tissues and fluids [14][15][16]. The appearance of the paediatric hip has been widely documented in control patients and in DDH cases [9][10][11][12][13][17][18][19][20][21][22][23][24].…”

“…Magnetic resonance imaging (MRI) has already been used in the determination of the adequacy of the surgical reduction of the dislocation of an immature hip [9][10][11][12][13]. Hip MRI protocols in post-reduction DDH patient assessment provides fast and adequate images without additional anaesthesia requirements or radiation exposure [9][10][11][12][13]. Since 2004, we have routinely used two-dimensional MRI in the coronal and axial planes to evaluate the adequacy of closed reduction of DDH in children.…”
