ABSTRACT
Introduction:
Complex fractures and extensive skin lesions are increasingly common due to high-energy traumas. An alternative for treating these lesions in the lower limbs is the use of the sural flap.
Methods:
This was a retrospective, analytical-descriptive study of exploratory documental analysis of patients submitted to the sural flap in a trauma reference hospital in northern Santa Catarina, Brazil. Age, sex, laterality, cause, place, and size of the lesion, use of tunneling and skin grafting, complications and their risk factors, and the management of such complications were analyzed.
Results:
The study sample consisted of 16 patients with a mean age of 44.4 years; 87.5% were male. The cause of the most prevalent lesion was trauma (75.0%), and the site of the lesion was more prevalent in the distal tibia (43.8%). In 50.0% of the cases, risk factors for complications were present, and patients with diabetes mellitus and smokers were five times more likely to present such complications. Partial necrosis had a prevalence of 25.0%, and in 18.8%, only debridement was performed, and 6.3% grafting was performed.
Conclusion:
The sural flap is a good alternative for covering lower limbs lesions due to its good success rate, but it is not free of complications. Such complications are more prevalent in patients who have risk factors such as smoking and diabetes mellitus.
