A central distal femoral physeal bone bridge in a boy aged 5 years and 7 months was resected with a fluoroscopically guided core reamer placed through a lateral parapatellar approach. At 3-year follow-up, the boy's leg-length discrepancy was 3.0 cm (3.9 cm preoperatively), and the physeal bone bridge did not recur. The patient had full function and no pain or other patellofemoral complaints. This technique provided direct access to the physeal bone bridge, and complete resection was performed without injury to the adjacent physeal cartilage in the medial and lateral columns of the distal femur, which is expected to grow normally in the absence of the bridge.
