Birth-Related Traumatic Proximal Femoral Physeal Separation: A Case Report.

Area of Science:

• Pediatric Orthopedics
• Neonatal Imaging
• Skeletal Dysplasia

Background:

• Birth-related injuries can present diagnostic challenges in neonates.
• Proximal femoral epiphyseal separation is a rare neonatal hip injury.
• Accurate diagnosis is crucial for appropriate management and prognosis.

Purpose of the Study:

• To highlight the diagnostic difficulties associated with neonatal proximal femoral epiphyseal separation.
• To illustrate the natural course and remodeling potential of this rare injury.
• To emphasize the role of advanced imaging in confirming the diagnosis.

Main Methods:

• Case report of a full-term neonate with left leg pain and limited movement.
• Initial radiographs misinterpreted as congenital hip dislocation.
• Ultrasound and serial radiographs utilized for diagnosis.
• Magnetic resonance imaging (MRI) confirmed separation of the proximal femoral epiphysis.

Main Results:

• Initial radiographic findings suggested hip dislocation but were contradicted by ultrasound.
• Callus formation observed on serial radiographs indicated healing.
• MRI confirmed separation of the proximal femoral epiphysis.
• No surgical or active intervention was required.

Conclusions:

• Neonatal proximal femoral epiphyseal separation can mimic congenital hip dislocation.
• Early diagnosis and appropriate imaging are essential.
• The neonatal hip demonstrates significant remodeling potential, often with favorable outcomes without intervention.
