RESEARCH CHARACTERISTICS OF DAMAGE AND ASSESSMENT OF TREATMENT SOFT TISSUE DEFECTS IN LOWER ONETHIRD OF THE LEG AND FOOT BY LATERAL SUPRAMALLEOLAR FLAP IN CAN THO CENTRAL GENERAL HOSPITAL IN 2021
Main Article Content
Abstract
Background: Soft tissue defect in foot and ankle is a common injury due to many causes, leaving many complications and complicated sequelae. Choosing the right treatment method is necessary, requiring that the method of coverage be simple, effective, easy to implement and have few sequelae. Further studies on the anatomy and application of skin flaps have increased the use value of flaps and lateral supramalleolar flap with skin thickness compatible with soft tissue at the ankles are also an option. Objectives: Characterization of lesions and assessment of treatment results for soft tissue defects in the lower third of the leg and foot with a lateral supramalleolar adipofacial flap on the outer ankle at Can Tho Central General Hospital. Materials and Methods: A cross-sectional, prospective study was conducted on 31 patients with soft tissue defects in the lower third of the leg and foot at Can Tho Central General Hospital from 2019 to 2021. Results:
Common defects in the ankle and foot area account for 93%. Most of the cases were found in men
(74.2%), in working age (average 28 years old), caused by traffic accidents and work accidents (67%). Most of the defects are completely covered, the skin flap has a high survival rate (87.09%). Most of the flap sites are closed directly, 4/31 (12.9%) have thin skin grafts for the flap donor area. There are 4/31 (12.9%) cases of skin flap necrosis, all of which are in the dermis. They are cared for by VAC (Vacuum-assisted closure) and skin grafting to cover the damage, 2, of which 3/4 (75%) complete healing and 1/4 (25%) cases with still inflammation were removed and additional skin grafts. In terms of aesthetics, the majority of patients are satisfied with the treatment results, the skin flap is similar in thickness and color to the flap site, the flap size is large enough to cover the lesion. Conclusions: The initial study showed that the skin flap on the lateral ankle was clinically effective in covering the soft tissue defects in the lower third of the leg and foot.
