Abstract

Introduction

Composite perigenual defects (CPGDs) are exacting the expertise of the reconstructive surgeons. Segmental skeletal defects continue to be a challenge for both orthopedic and plastic surgeons. There are many techniques available for the reconstruction of segmental skeletal defects in the perigenual region. This study explores the outcomes of pedicled chimeric propelled osteomyocutaneous fibula flap reconstruction of post traumatic and post excisional composite perigenual defects (CPGDs)

Materials and methods

It was a retrospective study conducted from 2011 to 2016 including 16 patients (5 post excisional defects and 11 post traumatic defects). 14 males and 2 females were included. Ages of the patients were ranging from 24 to 46 years. All had their CPGDs reconstructed with chimeric pedicled propelled fibula osteomyocutaneous flap

Results

All 15 patients on an average of 26 months follow-up assumed pain free unrestrictive walking. Fracture of hardware and transferred fibula occurred in one case 2 ^1/2 years following the surgery. Other patients had good functional recovery in an average of 26 months follow up. The average MSTS score of 15 patients was 23.9.

Conclusion

This anatomically construed procedure will be addendum to the armamentarium of reconstruction in both post excisional limb salvage milieu and secondary posttraumatic context for the perigenual composite defects. With high healing potential, infection culling capacity, high osteogenic potential and good supportive hardwares the pedicled osteomyocutaneous fibula flap may usher in better outcome in composite perigenual defects reconstruction.
