US hip newborns: why, when and how
fight against any disease occurs more quickly and easily than ever before it will be possible to detect.That is why only been born babies subjected to a whole set of surveys.US hip newborns for the first time held in the age of one month on the planned inspection at the orthopedist.
What is it?
survey is necessary for early diagnosis of hip dysplasia.It is defined as the underdevelopment of the hip joint in which the femoral head is beyond its natural location.In severe cases, children may experience hip subluxation and dislocation.
Due offset deteriorating bone metabolism in the joint.It destroyed the cartilage surface, that eventually leads to the development of other diseases - coxarthrosis Coxarthrosis - inflammation of the hip joints .There is a need to replace the "native" to the artificial joint.
According to different authors, dysplasia recorded at 0.5-4% of newborns.Formation of the disease occurs in the last months of fetal development under the influence of unfavorable factors, which include:
- oligohydramnios or polyhydramnios,
- breech presentation,
- mother gynecological diseases that hinder fetal movement (fibroids, adhesions Adhesions - both of themget rid of? uterus).
important value also has a genetic predisposition.If a child's disease was diagnosed in one of the parents, there is a great probability of its occurrence and the baby.
Some signs of the disease can be suspected by visual inspection.The asymmetry of the gluteal folds, different size feet, a small "wriggle out" legs during sleep Dreams: how to understand our dreams in infants with a high degree of probability suggest dysplasia dysplasia - What is it? hip.However, the disease often occurs in a latent form, so to detect its symptoms can not even an experienced orthopedic surgeon.Therefore, the only reliable method to identify or eliminate the problem, it is ultrasound.
ultrasound hip newborns: how is the procedure?
any special preparation for the examination is not required.It is desirable that the procedure was carried out no earlier than 30 minutes after feeding.This will reduce the likelihood of regurgitation, if a child comes to an excited state.
doctor puts the baby on its side and a special gel lubricates the hip.On the hip pose sensor and conduct research in five states: at rest, leg flexion and extension and abduction and to bring it to the torso.Then the procedure was repeated on the other side.
After visual assessment of orthopedic joints makes transcript obtained by the method of ultrasound photos Graf.For this paper carried out a series of lines and calculates angle indicators:
- acetabular angle (of the "bowl", which should be part of the femoral head).It is denoted by the letter α.
- dive angle of the femoral head in the acetabulum.It is designated as β.
Depending on the results, to make the final "verdict»:
- angle α of more than 60 degrees and less than 55 β hip in child build fine.
- angle α 50-59 degrees, and β a 55-70.Mild dysplasia or predvyvih.This means that the head of the femur and secured loosely moves freely in the joint.
- angle α 43-49 degrees, and β a 70-77.The average degree of dysplasia or subluxation.Femoral head partially outside of the joint.
- angle α less than 43 degrees, and β over 77. Severe dysplasia - dislocation.The femoral head completely slips out of the acetabulum.
first ultrasound hip baby should be held in 1-3 months.In the older age structure of joint cartilage ossify.This reduces the reliability of the method, and in the case of pathology, difficult treatment.
the presence of dysplasia ultrasound makes on a monthly basis to monitor the effectiveness of the therapy.If the joints are formed normally, repeat of the procedure is not required.
safety and contraindications
ultrasound are assigned to one of the safest methods.Unlike x-rays, it gives the minimum radiation dose, and in infancy can be used with a frequency of 2 times a month.
During the procedure, the child should be the maximum stationary.Therefore, it is important that at the time of ultrasound he was healthy.Colic, allergic reactions, viral infections can cause the baby anxiety.During the examination grudnichok starts crying, dodge, which leads to a distortion of the results.
