Many patients with hip dislocations are receiving braces, but there are many questions about when a brace is needed. What kind of brace should I wear? How long should the brace be worn? How to take care of the brace and what problems should be paid attention to during the process of bracing? Parents often consult us, so here are some common answers. For each patient, specific analysis is needed. 1.When do I need to wear a brace? Brace treatment is one of the means of conservative treatment for hip dislocation. It is mostly used for children aged 6-18 months who have simple acetabular dysplasia, subluxation or total dislocation after reset plaster fixation. 2.What kind of brace should I bring? At present, there are many different kinds of braces in China. However, no matter what kind of brace is used, if the angle of hip abduction exceeds 60 degrees, it is dangerous! The 90 degree abduction brace that is still in use is one of the most important reasons for the high incidence of ischemic necrosis and even severe necrosis of the femoral head in children with hip dislocation in China! In the medical market is still not very standardized, parents must pay attention to choose a good brace, otherwise it is counterproductive! 3.How long do I need to carry the brace? The duration of brace treatment generally does not exceed six months, and can be extended to 9 months in a few cases. The effect of prolonged application of brace is generally not good. 4.How to take care of the brace and what problems should I pay attention to during the process? It may be necessary to review the brace once every half month or once a month at the beginning, or once every 1.5 months afterwards. During the review, the doctor will check whether the brace fits properly, whether it needs to be adjusted, and how the hip joint is recovering. I use ultrasound more often in the review, so that I can reduce the radiation from multiple radiographs. When the ultrasound is normal, before deciding whether to remove the brace, it is important to take bilateral orthopantomographies of the hip to determine the recovery. The brace can be worn over soft fall clothing and pants, keeping an eye on the skin. While wearing the brace, the child can sit, lie down or hold it.
