Is obesity a risk factor in percutaneous hallux valgus surgery?

Obesity and its relationship with higher rate of complications in orthopedic surgeries have been reported. There is no evidence of the relation between obesity and percutaneous foot surgery. Our objective was to evaluate obesity as a risk factor for complications and reoperations in percutaneous surgery of the hallux valgus.

A total 532 feet were retrospectively reviewed in which a percutaneous hallux valgus correction was performed. Complications and surgical reoperations were recorded. Patients were divided into 2 groups: BMI less and greater than 30kg/m².

There were no differences in the rate of complications or reoperations. The total complication rate was 8%. Obesity as an isolated risk factor, presented aOR=1.14 (95%CI 0.54-2.4, p=.714). The overall rate of reoperations was 9%. Obesity presented an aOR=0.64 (95%CI 0.27-1.49, p=.31).

Obesity has not been associated with a higher rate of complications and reoperations in percutaneous hallux valgus surgery. It is a safe procedure and BMI should not influence in the prognosis.
