Summary
This study combined external fixation with intramedullary nailing for leg lengthening, reducing external fixation time and improving rehabilitation. While effective, a high risk of deep infection necessitates caution.
Area of Science:
- Orthopedic surgery
- Regenerative medicine
Background:
- Distraction osteogenesis is a common leg lengthening technique.
- External fixation often leads to complications like infection and joint stiffness.
Purpose of the Study:
- To evaluate a combined external fixation and intramedullary nailing method for leg lengthening.
- To reduce complications associated with traditional external fixation.
Main Methods:
- A cohort of 20 patients underwent leg lengthening using combined external fixation and intramedullary nailing.
- External fixation duration was monitored relative to length gained.
Main Results:
- A mean leg length gain of 4.7 cm was achieved.
- Mean external fixation time was 20 days/cm, shorter than traditional methods.
- All segments healed without refracture or malalignment; three deep infections resolved with treatment.
Conclusions:
- The combined method offers shorter external fixation times and facilitates early rehabilitation.
- It presents a lower complication rate compared to external fixation alone.
- Caution is advised due to a notable risk of deep infection.
