Ultrasonography has been suggested as a radiation-free alternative for evaluating callus formation. This study presents a case of a neonatal femoral fracture treated conservatively with the Pavlik harness, monitored with plain radiography and ultrasonography.

The patient progressed well through early rehabilitation and was ambulating independently by postoperative Day 8.
