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.
