Congenital Dislocation Of The Hip (Cdfi)

Congenital Dislocation Of The Hip (Cdfi) is a serious condition that can lead to dysfunction of the hip joint and even disability if not detected and treated promptly. This anomaly is usually discovered at birth or in the first months of a child's life.

The main cause of congenital hip dislocation is a violation of the formation of the pelvic and hip joints during pregnancy. This may be due to heredity, fetal development abnormalities, and poor conditions for fetal development. Also, the risk of developing Cdfi increases with the mother's first birth, high birth weight of the child, and low fetal position.

Symptoms of congenital hip dislocation include uneven folds in the hip, limited leg movement, uneven stride when walking, hip pain, leg length discrepancy, and a loud clicking sound that may be heard when trying to move the child's hip to the side.

Diagnosis of congenital hip dislocation includes examination by a doctor, ultrasound and x-ray examination. Treatment for Cdfi depends on the severity of the disease. In mild cases, where the hip can be easily returned to the acetabulum, a pelotion method is used, which involves wearing a special splint or bandage on the leg to hold the hip in the desired position. In more serious cases, surgery may be required.

It is important to note that congenital hip dislocation requires timely and comprehensive treatment. If the disease is not detected and not treated on time, it can lead to the development of osteoarthritis, impaired walking, deformation of the pelvis and hip, and disability.

Congenital Dislocation Of The Hip (Cdfi) is a serious disease that can lead to dysfunction of the hip joint and even disability in the future. Therefore, if you notice any symptoms in your child, you should consult a doctor and have a congenital hip dislocation diagnosed. In most cases, if the disease is detected and treatment is started on time, complete recovery and normal development of the hip joint can be achieved.

Congenital hip dislocation is the most common congenital pathology of the hip joint among all children under one year of age. The problem is solved promptly, since it is easily corrected only in the first 6 months of life. Surgery in 85% of cases leads to the child’s recovery. The remaining 15% are difficult cases, but they are, in principle, curable. But if the child is not operated on before 9 months of age, then I would not perform the operation on a 3-year-old child, a 4-5-year-old patient. And sometimes it is not necessary to undergo surgery for a child over 5 years old, since after the operation he may develop hip dysplasia (HD) or the so-called progressive instability of the hip joint (PHI).

If the PNS persists, it is recommended to undergo a CT scan rather than an x-ray (as usual) to exclude the presence of calluses. The recent tactic is to change surgical fixation to conservative. Surgical treatment does not improve the child's condition. If the dislocation persists until 8–10 months after it, the likelihood of developing DTS or PNS doubles.

Congenital hip dislocations are often the cause of secondary dislocations. They usually occur at school age or during school age. Paroxysmal pain in the projection of the affected joint, aggravated by movement and sitting, forced position of the limb,

Congenital hip dislocation is extremely rare. According to foreign literature, 0.3% is morbidity, 0.1% is disability in the child population. In terms of frequency of occurrence, it ranks eighth among other congenital malformations. However, its frequency in different regions of our country is not the same, leading to an average of 70% of dysostoses. The phenomenon represents a developmental defect (dysplasia) of various types of the femoral-pelvic structure.

In older children, OATB is diagnosed based on the determination of pelvic hypoplasia and shortening of one limb (usually the left) by 5 centimeters or more. In this case, the anterior angle of inclination of the acetabular edge, the size and depth of the acetabulum, and the morphology of the femoral head are determined. For a more accurate diagnosis, clinical interposition of the ossification nuclei, laterality of the median position of the nuclei, and nuclear planes are widely used. All diagnostic conclusions require mandatory documentary confirmation with the mandatory involvement of the child’s parents or parents over 18 years of age (through conversation).

In the process of diagnosing this pathology, an important place is occupied by determining the type of limb shortening, which is associated both with the constitutional norm and with hip dysplasia as such. The purpose of determining the type of shortened limb is not only to determine the functional relationship of the lumbar vertebra and the arch of the femur, but also to differentiate shortenings based on the risk of hip joint defects in order to identify a group of patients that need to be monitored and preventive measures taken.

Course of the disease: Among newborns from the first group of hip dislocations with a normal structure of the acetabular edges, subluxation and dislocation are observed, which disappears after 2-3 years of life. Along with this, cases of bilateral involvement are extremely rare, which is obviously a consequence of acquired dysplasia of both hip joints, previously involved and genetically linked in the context of the musculoskeletal system. The likelihood of bilateral hip dysplasia is often raised in multiple pregnancies or after fetal hypoxia due to pathology of placental development. In the second case, the dislocated hip is able to assume its proper position, and the uninjured hip is permanently subluxated, however, in both cases, only after several years of life, dynamic disturbances in the supporting function of both joints are determined
