Background and Objectives: Moderate congenital or developmental dysplasia of the hip (DDH) necessitates maintaining the femoral head completely contained within the acetabulum as a crucial step, in conjunction with corrective surgery. In fact, the conservative treatment within the orthotic parameters necessitates a good understanding of containment mechanics and mechanism, and it should be properly evaluated from an x-ray anteroposterior view or a computed tomography scan. This study aimed to improve the way the femoral head is held in place within the hip socket through a mechanical device or orthosis.
Case Presentation: A 2-year-old female patient presented with DDH, diagnosed since birth. Her parents reported concerns regarding her gait and asymmetrical posture, specifically observing a limp while walking and a limited range of motion in the right hip. However, they mentioned no other congenital anomalies and indicated that their child had received no previous treatments until this evaluation. An improvement in joint alignment and enhanced stabilization of the hip joint were observed, contributing to reduced laxity in the ligament and capsule. These effects promoted healthy cartilage development and facilitated the formation of the capitular sulcus. Additionally, the intervention played a preventive role against various complications, including kyphosis, leg length discrepancy, and osteoarthritis. Overall, the results confirmed improved functional performance and quality of life for the individual involved.
Conclusion: The amount of displacement in an avulsion fracture can be measured by x-ray checks or a computed tomography scan. The x-ray results revealed that the amount of displacement was approximately reduced to normal, resulting in normal encapsulation. This modified, newly designed articulated orthosis not only corrects the deformity but also permits normal flexion function.
