Case:
A full-term baby, born through emergency cesarean section, presented with pain and limited movement in his left leg. Radiographs at day 5 demonstrated superolateral displacement of the left femur, initially interpreted as a congenital hip dislocation. Ultrasound imaging demonstrated a normally positioned femoral head with no acetabular dysplasia, and repeat radiographs at 2-weeks revealed callus formation. Separation of the proximal femoral epiphysis was suspected and subsequently confirmed with magnetic resonance imaging. No active intervention was recommended, and 1-year radiographs demonstrated satisfactory remodeling.
Conclusion:
This report highlights the diagnostic challenges around this rare birth-related injury and demonstrates the excellent remodeling potential of the neonatal hip.

01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
