Summary
The reverse extensor digitorum brevis (EDB) muscle flap offers a reliable solution for dorsal foot defects. This technique provides robust vascularity and minimal donor site morbidity, making it a primary option for reconstruction.
Area of Science:
- Plastic Surgery
- Reconstructive Surgery
- Orthopedic Surgery
Background:
- Dorsal foot defects pose significant reconstructive challenges.
- Limited availability of suitable pedicled flaps for distal foot coverage.
- Free flap reconstruction is often required for even small defects.
Purpose of the Study:
- To evaluate the efficacy of the reverse extensor digitorum brevis (EDB) muscle flap.
- To assess its utility in reconstructing small- to medium-sized dorsal foot defects.
Main Methods:
- Retrospective study of 12 patients (Feb 2018 - Mar 2020).
- Mean defect size: 20.17 cm².
- Flap resurfaced with split-thickness skin graft; donor site closed primarily.
Main Results:
- Successful flap survival in all patients.
- Minor complications included graft loss (2) and donor site dehiscence (2), managed conservatively.
- Temporary sensory disturbance occurred in 3 patients, resolving within weeks.
Conclusions:
- The reverse EDB flap is a dependable option for dorsal foot defect reconstruction.
- Advantages include robust vascularity, low donor site morbidity, ease of technique, and good aesthetics.
- Recommended as a primary choice for small- to medium-sized dorsal foot defects.
