Percutaneous femoral distal epiphysiodesis using transphyseal cannulated screws is
commonly used for correcting anisomelia and angular deformity in adolescent patients.
Method: We report a case of previously unreported complication using cannulated screws:
The thread being damaged, the screw failed to block growth in the physis showed by the
releasing of a metal filament in the bone marrow after the screw's removal.
Results: The patient showed a limb length discrepancy necessitating a surgical correction.
The screw thread was damaged by the other device releasing a metal filament lodged in
the bone marrow.
The metal filament was released during the first operative gesture for Patient A, whereas it
occurred on the removal of the hardwire on the other example.
Conclusion: This report illustrates an uncommon complication using transphyseal screws
inherent to the Metaizeau surgical technique.
