Abstract

Objective To evaluate the use of external fixators in the delta-type kickstand configuration as an adjuvant method in the postoperative period of patients submitted to free flaps in the lower limbs.

Methods A total of 17 external delta fixators were used in patients submitted to free flaps in the lower limbs. The surgical technique was performed in a standardized manner, with the distal pin located 6 cm proximally to the anastomosis, and the proximal pin, 6 cm distally to the anterior tuberosity of the tibia.

Results The mean age of the sample was of 34.76 years (range: 15 to 66 years). In total, 11 men and 6 women were selected. The posterior tibial artery was used in 14 cases, and the anterior tibial artery, in 3 cases. The mean time of use of the external fixators was of 3.88 weeks. The rate of reoperation was of 17.64%; that of retail loss was of 11.76%; that of success rate was of 88.23%; and the rate of infection was of 5.9%.

Conclusion The use of delta-type fixators as an adjunct method in the postoperative period is reliable; however, more studies are needed to evaluate its true role in the postoperative period.
