Hip dislocation in infants refers to a structural problem within the hip joint. This condition is associated with a problem with the ball-shaped structure where the femur articulates with the hip, or the surface where this bone fits, called the acetabulum. Previously referred to as "congenital hip dislocation," this condition is now called "developmental hip dysplasia."

Developmental hip dysplasia, also known as hip dislocation in infants, typically describes a condition in which the rounded portion of the upper thighbone does not fully enclose the socket in the hip. This causes the joint to become misaligned, resulting in partial or complete hip dislocation. The vast majority of babies with this condition are born with it.

Doctors carefully examine babies' hip joints during regular checkups, both early after birth and throughout the following years. Hip dislocation detected in the newborn period can be corrected with treatments such as soft braces. Therefore, awareness is crucial, and early diagnosis can increase treatment success.

What causes hip dislocation in babies?

The factors that cause hip dislocation in babies can vary. While this condition is more common in girls than boys, any baby can develop a hip dislocation. Therefore, doctors regularly examine babies' hip joints using various methods, starting from the newborn period.

While the exact cause of hip dislocation is difficult to pinpoint, various factors are believed to be at play. While it's generally more common in first-born girls, hip dislocation can occur in as many as four out of every 1,000 newborns.

Some conditions that increase the risk of hip dislocation in infants include:

• Presence of other family members with a history of hip dislocation
• Babies born with a breech presentation
• Problems with placement in the womb
• A condition called oligohydramnios, which is a lack of intrauterine fluid.

Problems with fetal positioning can be associated with conditions such as clubfoot or crooked neck in the baby. Hip dysplasia is generally seen in approximately 80% of first-born babies, and the rate of hip dysplasia in the left hip is approximately 60%. However, the possibility of hip dysplasia in any baby should not be ignored, and regular checkups recommended by a doctor should be performed.

What are the symptoms of hip dislocation in babies?

Some babies with hip dislocation may have mild or no symptoms at all. However, some babies may have symptoms that may indicate hip dislocation, such as:

• Positionally turned legs outward: The baby's legs may be in a position where they turn outward more than normal.
• Leg length discrepancy: In babies with hip dislocation, there may be a discrepancy between the legs. One leg may appear shorter or longer than the other.
• Decreased range of motion of joints: The baby's ability to open their legs wide or fold their legs inward may be limited.
• Differences when the baby's legs are lifted up: When the baby's legs are lifted up, it may be observed that the folds are not symmetrical or there is less movement in one leg.
• Delay in motor skills: In babies with hip dislocation, there may be delays or significant differences in motor skills such as sitting, crawling and walking.

The presence of one or more of these symptoms may indicate a hip dislocation. However, even in the absence of any symptoms, doctors carefully examine the hip joint in infants during routine checkups. If you notice any of these symptoms or have any concerns, it's important to consult a doctor.

What are the risk factors for developmental hip dislocation?

Risk factors for developmental hip dislocation include a variety of conditions that can affect the normal development of a baby's hip joint. Some risk factors include:

• Babies born from first pregnancies : There may be an increased risk of hip dislocation in babies born at first birth.
• Multiple pregnancies: In multiple pregnancies such as twins or triplets, the risk of hip dislocation may increase due to the placement positions of the babies and spatial restrictions.
• Being in a breech position at birth: If the baby is born or develops in a breech position, the risk of hip dislocation may increase.
• Family history of hip dislocation: Familial cases of hip dislocation may suggest that genetic factors may play a role, and in this case, the risk of hip dislocation in the baby may increase.
• Oligohydramnios (low amniotic fluid): Limited movement of the baby in the womb or low amniotic fluid can affect the normal development of the hip joint and increase the risk of dislocation.
• Swaddling: Traditional swaddling methods can move babies' legs out of their natural position and increase the risk of hip dislocation.

These risk factors may increase the risk of hip dislocation in infants, but they do not constitute a definitive cause. As a preventative measure, it's important for infants to have regular checkups and consult a doctor if symptoms occur.

Does a baby with hip dislocation cry?

Babies with hip dislocations typically don't exhibit any specific symptoms other than crying. Babies typically cry to express needs, discomfort, or distress. However, hip dislocations don't directly cause crying, and the condition isn't specifically associated with crying.

Babies may cry when they experience discomfort or discomfort. However, a condition like a hip dislocation is not usually directly associated with crying. The crying of a baby with a hip dislocation is often associated with other symptoms of discomfort or is not caused by the hip dislocation.

How does a baby with hip dislocation walk?

The gait pattern of a baby with a hip dislocation may vary depending on the child's age and the severity of the condition. However, in general, babies with a hip dislocation may experience some symptoms while walking.

When a baby reaches the walking stage, one of the first signs of hip dislocation is that one leg appears longer than the other when standing. This may be a significant difference in leg length.

When a baby with a hip dislocation begins to walk, a limp or unsteady gait is often observed. The baby may use one leg less than the other or bear less weight on that leg. This may manifest as a noticeable limp when the baby begins to walk.

However, these symptoms may not always be present in a baby with a hip dislocation, or they may not be the same in every baby. If you notice such symptoms while your baby is walking or if you have any concerns, it's important to consult a doctor. A proper medical evaluation and examination can help you make an accurate diagnosis of hip dislocation or other possible conditions.

Does hip dislocation cause pain in babies?

Hip dislocations are generally painless in infancy, and babies don't exhibit any obvious signs of pain. However, in rare cases, pain may be experienced in babies with hip dislocations.

Pain symptoms are often unnoticed in babies with hip dislocations, especially during infancy. However, hip dislocations left untreated or uncorrected until adolescence can cause problems later in life.

Untreated hip dislocations during adolescence and young adulthood can lead to serious, painful complications such as osteoarthritis later in life. Therefore, if hip dislocation is detected or symptoms are noticed in infancy, it is important to consult a doctor as soon as possible and consider appropriate treatment options.

Although pain is rare in cases of hip dislocation in infants, early diagnosis and treatment are essential to prevent potential complications later in life. Therefore, if you have any concerns or notice any symptoms, a healthcare professional should be consulted.

How is hip dislocation diagnosed in babies?

Hip dislocation in infants is a condition that can be detected during regular checkups from birth. Evaluations performed by physicians, particularly during infants' first checkups, can indicate normal hip joint development or indicate abnormalities.

The basic examination tests used to diagnose hip dislocation are the Barlow and Ortolani tests. These tests evaluate hip joint function. In infants with hip dislocation, abnormalities may occur in the joint area because the hip joint has not developed normally. During the Barlow and Ortolani tests, any clicking sound or sensation detected when the hip is in a different position than normal can be interpreted as an abnormality.

The Ortolani test is performed by moving the baby's legs outward, while in the Barlow test, the legs are moved inward.

These tests are only effective in infants younger than 3 months. Therefore, ultrasound is preferred for evaluating hip dislocation in older infants or children. Ultrasound provides detailed information about the hip joint. During this examination, the joint position and surface are examined. If an abnormality is present, it may be determined that the surface of the hip bone that joins the joint or that the surface of the hip bone is shallower than normal.

Radiographic evaluation (X-ray) is not preferred, particularly in the neonatal period, due to the immaturity of bone mineralization. Ultrasound is very useful in diagnosis and monitoring treatment. Therefore, if a hip dislocation is suspected, it is important to perform the tests recommended by the doctor and seek specialist advice.

What is the treatment for hip dislocation in babies?

Treatment of hip dislocation in infants requires early diagnosis and intervention. Treatment varies depending on the baby's age and the severity of the joint problem.

Pavlik pads are often used for neonatal hip dislocations. These pads support the hip joint for several months by ensuring the bone structure in the joint aligns with the joint socket. Pavlik pads can help with recovery by improving the alignment of the joint structures. However, this treatment method may not be effective in infants older than 6 months. In this case, a different pad applied to cover the entire body may be preferred over the double-pad Pavlik pad.

In some cases where bandaging is insufficient, surgery may be considered. While surgery can be successful in various cases, some may require multiple procedures. While early treatment with Pavlik bandages can achieve a success rate of 80% to 95%, surgical interventions can be more variable.

Hip dislocations that are not diagnosed and treated early can lead to problems such as severe pain and arthritis later in life. Therefore, the earlier treatment begins, the higher the chance of success.

Treatment for hip dislocation in infants requires an individualized approach. Because every case is different, it's important to follow your doctor's recommended treatment and schedule regular checkups.

Can congenital hip dislocation be prevented?

It's often impossible to completely prevent developmental hip dislocation. However, regular screening tests can help detect hip dislocation as early as possible. Early diagnosis can help make treatment easier and less complicated.

It's thought that swaddling babies' legs too tightly can negatively impact hip development. Therefore, it's important to avoid swaddling your baby too tightly and allow them to move freely. Wearing clothing that allows your baby to move freely and allows their legs to move freely can help reduce the risk of hip dislocation.
