Summary
Vascularized fibular epiphyseal transfer for bone defects in children is effective. Postoperative foot drop is usually temporary, with most patients recovering function within six months.
Area of Science:
- Orthopedic surgery
- Pediatric reconstructive surgery
Background:
- Vascularized epiphyseal transfer reconstructs bony defects in skeletally immature individuals, preserving growth and joint function.
- The proximal fibula is a suitable donor site due to its size, remodeling capacity, and low morbidity.
- Peroneal nerve dysfunction leading to foot drop is a potential complication.
Purpose of the Study:
- To prospectively evaluate the incidence and recovery of peroneal nerve dysfunction after vascularized fibular epiphyseal transfer.
Main Methods:
- Sixteen patients underwent vascularized fibular epiphyseal transfer.
- Clinical (MRC score) and electromyographic assessments were performed preoperatively and up to 24 weeks postoperatively.
- The study was registered as a clinical trial (NCT05884827).
Main Results:
- Four of 16 patients developed transient foot drop (MRC grade 0).
- All affected patients recovered function within 24 weeks.
- Electromyographic abnormalities in these patients normalized within 24 weeks.
Conclusions:
- Peroneal nerve dysfunction (foot drop) following vascularized fibular epiphyseal transfer is typically transient.
- Most patients experience clinical and electromyographic recovery within six months.
