Description
Summary:To investigate whether the technical modifications regarding the risk factors related to the partial necrosis of the distally pedicled sural flap could reduce the partial necrosis rate of the flap. A clinical data of 254 patients (256 sites) (modified group), who used modified technique to design and cut distally pedicled sural flaps to repair the distal soft tissue defects of the lower limbs between April 2010 and December 2019, was retrospectively analyzed. Between April 2001 and March 2010, 175 patients (179 sites) (control group) who used the traditional method to design and cut the skin flap to repair the distal soft tissue defects of the lower limbs were compared. Various technical modifications were used to lower the top-edge of the flap, reduce the length-width ratio (LWR) of the flap and width of the skin island. There was no significant difference in gender, age, etiology, duration from injury to operation, site and area of the soft tissue defect between groups ( >0.05). The length and width of the
