The nucleus of ossification of the hip joints: normal and pathological

Ядра окостенения тазобедренных суставов: норма и патологииThe condition of the musculoskeletal system and hip joint are closely interrelated. The process of ossification of the hip joints occurs in a person gradually and ends at the age of 20 years. The school of bone tissue occurs in utero. At this time the fetus begins to form the hip joint.

If the baby is premature and born early, at the time of birth of the nucleus at the joints will be small. This deviation may be in term infants, they too often found the lack of nuclei of ossification. In most cases, this is a pathology affecting the development of locomotor apparatus. If the kernel in the first year of baby’s life don’t get development, the proper functioning of his hip joints is jeopardized.


Types of pathologies of the nuclei of the hip joint

Ядра окостенения тазобедренных суставов: норма и патологииThe health status of the newborn is the main criterion, in which case, slow development of nuclear norm and in a pathology. If the child has no dislocation in this area, in this case, the slow development of nuclei is not assessed as a dangerous pathology. When not disturbed the normal functioning of the hip joints, but the kernel is evolving slowly, this too is not a dangerous process. When the baby disturbed the functioning of the musculoskeletal system, there is a dislocation in this area, and both these phenomena occurred due to the lack of nuclei of ossification, pathology is dangerous. It harms the health of the child and disrupts the growth, development, flexibility of the joints located in this region.

Immediately have to clarify: this pathology of the bone of the hip joint is mostly found in newborns, babies and children, whose age is not more than a year. The condition of the musculoskeletal system depends on the intrauterine development of the child. When a woman is 3-5 months pregnant, the baby is laying bone tissue that will become the basis of his limbs. Nuclei of ossification are key to normal development of the musculoskeletal system of the child. At the time of the birth of a baby they grow up to a diameter of 3-6 mm. When the nucleus of ossification reach this value, it is an indication that the bones and tissue of the fetus are progressing normally. If the baby will be born full-term, this fact also will positively affect the further development of the musculoskeletal system.

However, in clinical practice there are a lot of cases, when a full-term, normally developing in the womb children have problems development of the hip joint. For a number of fully not yet known to science causes such nuclei they simply do not exist. This occurs in 3-10% of children.

The joints of the pelvis are completely formed by the 8th month of pregnancy

Temporary rate of development of the nucleus of ossification is not the same for all, as some signs of the formation of these tissues. There are cases when the kernels do not develop in the fetus to 8 months pregnant women, and this process slows down the tab themselves of tissues. Then the kid without the influence of any external factors rapidly begins to develop the hip joint.

In such cases, at 8 months pregnant core reaches the normal size, not differing in structure and shape from those formed from other children when their mothers were at 3-5 months pregnant. And as late in the development of the tissues in this region no marked deviations.


The factors causing the ossification

With the development of the child to his hip increased. A similar process happens with the nuclei. There are a number of negative factors, which may cause a delay in their increase, that is cause ossification. It should be noted: the same reasons have a negative impact on the growth of the hip joint.

The ossification is suffering every second child who has rickets, because the tissues because it is sorely lacking nutrients. Vitamins and minerals are not getting in the required volume of muscle tissue, ligaments, tendons, bones.

If dysplasia in babies legs don’t get divorced

If the baby has dysplasia and hip suffering, it will negatively affect the formation of nuclei. Most often they develop slowly in children on artificial feeding. It weakens the child’s immunity and does not impact positively on their tissue.

The main symptoms of the dysplasia in children believe:

  • asymmetry of skin folds;
  • the restriction to abduction of the thigh;
  • the clicking symptom (symptom slide);
  • external rotation of the thigh;
  • the relative shortening of the limb.

The health status of both parents is often the major cause of arising of the baby pathologies of the hip joint. A special role in this process plays the mother’s health, which is reflected in the cores. As shown by medical studies, if parents have diabetes, this — the child will develop slowly. Have a toddler and a hip will form much more slowly than their peers. In such situations, require a package of measures aimed at stimulation and development of locomotor apparatus. Such assistance is necessary for many kids whose parents suffer from thyroid diseases. — These children are developing slowly. In parallel with this process, there are signs of infringements of a metabolism, hindering the development of the hip joint. All this affects the formation of the primary tissues in the pelvic region.

An important factor affecting the health of the unborn child and the development of his hip joint, is how was the pregnancy of the woman. The kernel may be missing or may develop slowly with breech, transverse, breech presentation of the fetus.

Comparison of healthy and diseased joint

Pathology in this area often arise from malposition of the growing baby in the womb. — The fetus may not begin to form due to the lack in the mother’s body of vitamin E and is essential for the process of minerals: calcium, phosphorus, iodine, iron. All this affects the development of the baby. Hormone disruption, multiple pregnancy, viral and infectious diseases of the mother, having her gynecological problems during pregnancy are all causes, which — will not develop.

An important point is the genetic predisposition to diseases of the hip joint. A number of pathologies in this area can be inherited. Premature birth, environmental factors also influence how is the kernel. But, as research shows that in every fifth case, the malfunction due to genetic reasons.

No less dangerous factor is the underdevelopment of the spine and spinal cord from the mother. It also affects the condition of the musculoskeletal system of the baby. Increased tone of the uterus is not lost on the development of the fetus, it can often provoke disturbances in the development of the musculoskeletal system of the child.

Hypertonicity of the uterus in some cases can be the root cause of what is not formed or slowly evolving core.


The first measures to help child

The child in the first year of life the hip joint needs to stabilize. The neck of the femur is gradually ossified. In parallel, it strengthens the ligaments, the centralization of its head. Acetabulum should reduce the tilt angle to musculoskeletal system of the baby could function properly.

Ядра окостенения тазобедренных суставов: норма и патологии— Ossification particularly active is formed from the 4th-6th month of life, in 5-6 years it the baby increases in average 10 times. In the 14-17 years of age the cartilage is replaced by bone. Femoral neck will grow even up to 20 years, by that time your hip will be formed in place of the cartilage is bone.

If he is developed correctly, the femoral head will not be able to resist in the cavity of the hip joint, which is a symptom of dysplasia. To prevent the disease in that area, at the slightest breach in their formation of the child without delay to consult a doctor. If the hip joint is associated with the development of the core pathology, it detects ultrasound. To identify and apply methods of sonographic study. Often you may need and x-ray examination of the pelvis. X-ray this is performed in direct projection. It allows physicians to obtain the most accurate information about the presence or absence of pathology.

There are special orthopedic devices to ensure that the hip joint of the child was developing normally. When there is a delay in the development of his head, orthopedic treatment and prevention of rickets. In such cases, doctors prescribe and wearing a special splint. It effectively strengthens electrophoresis and massage. To stabilize the hip joint help bath with sea salt and paraffin baths.

If the baby is ossification, parents definitely need to take care that his hip joint was not damaged. To plant or put the baby on the legs is strictly forbidden until it is strengthened and stabilized the hip joint.


Prevention for moms

Even if a family has a predisposition to ossification of hip dysplasia, there is always a chance to prevent the disease. Competently preventive measures undertaken will protect the developing hip joint of the fetus. It all starts with nutrition. During pregnancy a woman should receive all the necessary vitamins and minerals. They will participate in the formation of all joints of her unborn child. At the slightest signs of vitamin deficiency the baby should immediately see a doctor. Beriberi, and rickets that affects musculoskeletal system of the baby.

During lactation, a woman should receive a balanced diet, to and hip the baby has received all the necessary minerals and trace elements. To musculoskeletal system develop normally, a child 7 months to get a ration of supplementary food. For the development of the musculoskeletal system to useful walk in the fresh air, massage, exercises, hardening of the baby. However, all these procedures should be agreed with your doctor, who will help you choose a set of measures for the development of the hip joint.

In autumn and winter, to prevent the baby should definitely be taking vitamin D, needed for normal functioning and growth.
