What Is Pediatric Hip Dysplasia?
Pediatric hip dysplasia, also known as developmental dysplasia of the hip (DDH), is a condition where a child’s hip joint does not form properly. The hip is a ball-and-socket joint, and in children with DDH, the ball (femoral head) may be loose in the socket or may not sit in the socket at all. This can lead to dislocation, joint instability, and long-term joint problems if left untreated. Early diagnosis and intervention are crucial to prevent complications as the child grows.
When Is Surgery Needed for Hip Dysplasia in Children?
While many cases of DDH in infants can be corrected with non-surgical treatments such as a Pavlik harness or bracing, surgery becomes necessary when these methods fail or the child is diagnosed at an older age. Surgical intervention is generally considered when the hip remains dislocated despite months of conservative treatment, or if the condition is diagnosed after walking age. Surgery ensures that the hip is positioned correctly within the socket to promote proper development and mobility.
What Types of Surgery Are Performed for Pediatric Hip Dysplasia?
The type of surgery depends on the child’s age, severity of the dysplasia, and the condition of the joint. The most common procedures include closed reduction, open reduction, and osteotomy. In closed reduction, the surgeon manually manipulates the hip joint into the socket without making an incision, often followed by a body cast to maintain position. In open reduction, an incision is made to access the joint and remove any obstructions before repositioning the hip. Osteotomy involves cutting and realigning the bones of the hip or pelvis to improve joint stability and function.
How Is the Child Prepared for Surgery?
Before surgery, the child undergoes several imaging tests, such as X-rays, MRI, or ultrasound, to assess the condition of the hip. The surgical team provides specific instructions regarding fasting, medication, and anesthesia protocols. A pediatric anesthesiologist typically handles sedation to ensure the child is safely asleep and pain-free during the procedure. Parents are also given guidance on what to expect before, during, and after the operation to help ease the child’s anxiety and ensure a smoother experience.
What Happens During the Surgery?
During the procedure, the surgeon makes careful adjustments to properly position the femoral head within the socket. Depending on the approach, soft tissues may be loosened or tightened, and bones may be reshaped to improve alignment. The hip is then held in place using a spica cast, which keeps the hip joint immobilized for healing. The surgery typically lasts 2 to 4 hours, depending on the complexity of the case.
