A Comparison of the Device-Related Complications of Intramedullary Lengthening Nails Using a New Classification System

Figure 4

(a) A 38-year-old woman who underwent bilateral femur lengthening complained that she abruptly cannot be able to control her left leg, just after “popping sense” on the leg during early consolidation phase. To confirm the failure of rotational stability of the nail, the CT scans of lower extremity with maximal internal and maximal external rotation were taken, respectively. The femoral rotational alignment changed to about 20 degrees according to the patient’s position. (b) Additional mono-fixator was applied to gain a proper rotational alignment and stability until the consolidation is finished.
