Patient's question:
Patient gender: Female; Main symptoms: Hip dysplasia; Onset time: 7 months; Laboratory test results: The femoral head has not grown out.Doctor's answer:
The disease is divided into three categories based on the severity of hip joint issues: one is simple hip dysplasia, the other is hip dysplasia combined with subluxation, and the third is hip dysplasia combined with dislocation. Children with developmental hip dysplasia often experience hip dislocation shortly after birth, frequently presenting with leg length discrepancy, asymmetrical skin folds in the buttocks and thighs, and the inability to touch the bed surface with the normal lateral aspect of the knee. If not treated promptly, it can lead to dislocation, joint stiffness, limited joint mobility, and in severe cases, avascular necrosis of the femoral head. Additionally, clinical statistics show that the effectiveness of treatment is closely related to age—the younger the patient, the simpler the treatment, and the better the outcome. Therefore, early treatment is key to improving cure quality, which relies on early diagnosis and detection.With the advancement of medicine, the "early" stage of diagnosis is no longer limited to parents noticing their child's leg abnormalities but has been pushed forward to shortly after birth. Clinically, it is often found that when parents visually detect abnormalities or when children show symptoms during the early walking stage before seeking medical attention, the hip joint has already dislocated, indicating a severe condition with significant treatment challenges. If early detection and treatment are initiated during the infant's developmental, it can greatly reduce the likelihood of limb deformities during later walking stages.
