Efficacy of Pie-Crusting Technique on Soft Tissues in Distal Tibia and Fibula Fractures.

Distal tibia and fibula fractures are challenging injuries to treat as evidenced by the high rates of wound complications because of vulnerable soft tissue coverage. The aim of this study was to examine the effect on soft tissue complications of the pie-crusting technique when applied between 2 incisions in distal tibia and fibula fractures treated with open reduction and internal fixation. We reviewed 34 patients with distal tibia and fibula fractures treated between September 2014 and March 2017. The pie-crusting technique was performed during wound closure in 16 (47.06%) fractures (group 1) and classic wound closure was done in 18 (52.94%) fractures (group 2). The primary outcome was evaluated as the presence or absence of soft tissue complications such as superficial skin necrosis, deep skin necrosis, and deep infection. The mean age was 50.44 ± 13.51 (range 23 to 65) years in group 1 and 51.67 ± 14.49 (range 18 to 68) years in group 2. The mean follow-up time was 27.35 ± 9.02 (range 16 to 46) months. The mean surgery time after injury was 5.88 ± 3.5 (range 1 to 14) days in group 1 and 7.32 ± 4.25 (range 1 to 16) days in group 2. No soft tissue complications were seen in any patient in group 1. Five (27.77%) occurrences of superficial skin necrosis were observed in group 2. In 2 (11.11%) patients in group 2, deep necrosis and wound dehiscence occurred, and subsequent deep infection developed in 1 (5.55%) of these patients. The overall complication rate was higher in group 2 (p = .005). We believe that the pie-crusting technique is beneficial for wound closure in distal tibia and fibula fractures, because it reduces the tension of the skin and allows leakage of subcutaneous fluids.
