Single-stage reconstruction of Achilles tendon injuries and distal lower extremity soft tissue defects with the reverse sural fasciocutaneous flap.

ABSTRACT

OBJECTIVE: Complex wounds of the lower extremity with concomitant Achilles tendon injury can be difficult to reconstruct. We favour the reverse sural artery fasciocutaneous flap because in a single step, flap elevation affords Achilles tendon exposure and adequate soft tissue for reconstruction. It also provides significant time and resource savings for both plastic and orthopaedic surgical teams. MATERIALS AND METHODS: Our case series involved four consecutive patients who presented with Achilles tendon injuries and concomitant complex soft tissue defects. The reverse sural artery flap was planned in conjunction with the orthopaedic service to facilitate their approach for Achilles tendon repair. Outcome was measured as flap survival, time for flap elevation and total operative time. RESULTS: Partial flap loss occurred in one patient. The Achilles repair was performed successfully in all cases. The mean time for flap elevation and Achilles exposure was 43 min (range, 37-52 min). Total operative time was 287 min (range, 211-347 min). CONCLUSION: The reverse sural artery fasciocutaneous flap is a durable, efficient option for simultaneous Achilles tendon reconstruction and wound coverage. Simple flap elevation provides necessary exposure of the Achilles tendon for repair while the flap itself provides ample soft tissue with a reliable blood supply. In our experience, the reverse sural artery fasciocutaneous flap affords a practical method to address two reconstructive challenges in a single procedure.
