Surgical management of the skin defect in the lower third of the leg

Loss of substance from the lower third of the leg is extremely common, most often of traumatic origin. The management of the loss of cutaneous substances from the leg is a complex procedure due in particular to the specific anatomy of the leg segment and its lack of skin reserve, venous return problems, macro/micro-angiopathic disorders related to trauma or increasingly frequent acquired comorbidities (smoking, occlusive arterial disease of the lower limbs, diabetes, etc.). It must therefore be multidisciplinary and requires close collaboration between orthopaedic and plastic surgeons. The choice of coverage will depend on the etiology of the claim, its location and the state of the area to be covered. The treatment will follow the principle: parry, fix, cover. The evolution is favourable, considered satisfactory both aesthetically and functionally. The objective: The objective of our study is to highlight the particularity of skin substance losses, their epidemiological and therapeutic aspects, while highlighting the difficulty of coverage We conducted a retrospective study of a series of 56 cases of leg covers at the CHU MOHAMMED VI DE TANGIER from the year 2022 to 2024. Several parameters were studied: age, sex, etiopathological factors, location and the therapeutic methods used
