The traditional Ilizarov frame is a heavy external structure that must remain attached throughout both the lengthening and consolidation phases. Prolonged frame use can cause discomfort and increase the risk of complications.
To reduce the duration of external fixation and improve patient comfort, the Lengthening Over Nail (LON) technique is used.
The frame remains in place until the desired length is achieved through gradual distraction.
Patients are allowed early mobility and partial weight-bearing with crutches or walker support.
Significantly reduces the duration of external fixation compared to traditional frame-based methods.
Reduced complications associated with prolonged frame use and extended external fixation.
Provides better comfort during the consolidation phase compared to full-frame lengthening.
Helps maintain correct alignment and prevents axial deformity during and after the fixation process.
Maintains strong mechanical stability to support long-term bone alignment and healing.
The combination of intramedullary nailing with an external fixator provides a balanced approach — reducing frame duration while maintaining surgical safety and biomechanical stability throughout the lengthening process.
