RESUMO
Objective: To determine the effect of mechanism of injury on wound healing, and on the viability and success of distally based sural flap when used for the coverage of defects of lower leg, ankle and foot
Study Design: Descriptive study
Place and Duration of Study: Department of Surgery, Combined Military Hospital, Peshawar and Khariyan, from January 2012 to December 2014
Methodology: Patients with soft tissue defects over the distal leg, ankle and foot were selected by purposive sampling technique and divided into 2 groups of 19 patients each. Group A [road traffic accidents] and group B [war injuries]. Sural fascio-cutaneous flap was the reconstructive tool used in all the cases using single technique by the same surgical team; and time for recipient site preparation, size of the defect, graft survival, its healing time and complications, were studied
Results: The mean age of the 38 patients in the study was 28.2 +/- 13.4 years. There were 36 male and 2 female patients. The most common site of injury encountered was leg [n=20] followed by foot [n=11] and ankle [n=5]. Maximum wound size seen in group A was 10 x 12 cm and in group B was 15 x 38 cm. Recovery was uneventful in 17/19 cases of group A while 7/19 in group B and with no graft failure. Superficial epidermolysis was seen in 2 and 8 cases in group A and B respectively while edge necrosis of the flap was observed in group B only [n=4]. Healing time on average was 2 to 3 weeks in group A, and 4 to 5 weeks in group B
Conclusion: Soft tissue defects of the distal lower extremity as a result of war injuries and road traffic accidents have different dynamics in terms of wound size, time of wound healing, wound complications and functional outcome; but distal based sural flap has promising results in both situations
