Case Report: Reconstructive Ankle Surgery

Abstract

BACKGROUND: Diabetes mellitus is a major public health problem, according to the World Health Organization, 422 million adults worldwide in 2014. In 2012, it caused 1.5 million deaths worldwide. Diabetes is the leading cause of non-traumatic amputation in lower limbs and foot infections occur with high frequency in poorly controlled patients. This case shows the reconstruction of soft tissue defects in the lower third leg, heel, malleoli and foot through the description of the reverse sural flap. In this study the advantages and disadvantages of the use of this technique are discussed. CASE REPORT: A 56-year-old female patient with a poorly controlled history of Diabetes Mellitus type 2, who suffered a fracture of the left ankle treated with osteosynthesis, and who during the postoperative period attended emergency orthopedics and traumatology, due to severe pain in the left ankle, fever, dehiscence of surgical wound, accompanied by serous secretion. EVOLUTION: The patient, after several surgical cleanings and changes in closure therapy assisted by negative pressure, manages to control the infection, with persistence of the bone coverage defect and the osteosynthesis material. There were additional complications such as joint stiffness, muscle atrophy; it was decided to reconstruct the distal third of the foot using a reverse flow sural fasciocutaneous flap, which evolved satisfactorily, managing to cover the defect with biological tissue. CONCLUSIONS: The sural flap of reverse flow is a reproducible technique that allows to cover coverage defects in the distal third of the leg and ankle; shorten hospitalization times, especially when there is bone exposure or osteosynthesis material.
