Symptom Barlow (Barlow S Sign)

Barlow's Sign

Barlow's sign is one of the clinical signs that may indicate the presence of congenital hip dislocation in a newborn or young child.

This symptom is as follows: when the hip and knee of the sprained leg are flexed 90 degrees, the big toe of that leg rotates outward instead of the normal inward rotation. This occurs due to the abnormal position of the proximal femur in the hip joint.

The Barlow sign is often used to screen for congenital hip dislocation in newborns, along with other tests such as the Ortolani sign and Galeazzi sign. If a pathology is suspected based on screening results, it is necessary to conduct an additional examination (X-ray, ultrasound) to make a final diagnosis.

Timely detection of congenital hip dislocation is very important in order to begin treatment of this condition as early as possible and prevent the development of persistent impairments and disability of the child.



Barlow's sign (Barlow S Sign) is one of the signs of congenital hip dislocation. It was named after the English surgeon Thomas Barlow, who first described this symptom in 1962.

The essence of Barlow's symptom is that when you try to bend a child's leg at the knee joint and at the same time gently press on the thigh in the direction of its head, you can cause hip dislocation. This symptom usually appears in children between 4 and 6 months of age.

Barlow's sign can be used to diagnose congenital hip dislocation, which is a fairly common disease in newborns. However, congenital hip dislocation can lead to further health problems such as chronic pain, scoliosis and other orthopedic problems.

It is worth noting that Barlow's sign is not the only sign of congenital hip dislocation. In addition to this, there is also Von Rosen's sign, which is that when you try to move the child's hips apart, you can feel a crunch or click, which is also a sign of hip dislocation.

To diagnose congenital hip dislocation, you must consult an orthopedic doctor who will conduct the necessary tests and prescribe treatment. In most cases, congenital hip dislocation can be successfully treated with conservative methods, such as wearing special orthopedic bandages or exercises aimed at strengthening the muscles and ligaments of the hip.

Thus, Barlow's sign and Von Rosen's sign are important signs of congenital hip dislocation that must be diagnosed and treated promptly to avoid further health problems. If you suspect that your child has a hip dislocation, you should contact an orthopedic doctor for consultation and treatment.



Barlow's sign or symptom is a symptom that occurs with congenital dislocation of the hip. This condition occurs when the femur is tilted away from the acetabulum by more than 45 degrees. Normally, both joints of the body are symmetrical relative to each other. When the hip joint is dislocated, coordination of movements of the head and limbs is disrupted. This makes it difficult to walk. With Barlow's symptom, impaired coordination of movements is more pronounced.

The symptom was named after the American doctor Barlow S. He was one of the first to notice that when a leg is dislocated, the so-called “patient behavior with torr” appears.
