Hrev_master Veins and Lymphatics 2016; volume 5:5988 Compression after trauma Rolf Jelnes Wound Clinic, Medical Center, Sygehus Sønderjylland, Sønderborg, Denmark Traumatic ulcers are a large entity in wound care. In our clinic, data from the database1 show that the number of patients is compara- ble to venous leg ulcers, diabetic foot ulcers and pressure ulcers (Table 1). In spite of this, not very much is written about the entity in the literature. The traumatic wounds are typically located on the anterior and lateral aspect of the lower limb. The causes are different from low energy trauma (as stumbling up the stairs or a trolley in the supermarket (Figures 1 and 2) to acci- dents with a sharp trauma. After low energy trauma, the patients are able to continue their daily work until a lesion appears on the skin. When it increases in size the patient seeks the General Practitioner who typically prescribes an antibiotic treatment. If nothing else is done, apart from moist wound healing, the time to heal can be as long as more than 6 months with the well known con- sequences for the patient and the society in terms of personal and social costs. Studies on deep tissue injury have shown that cell deformity, within minutes, causes cell damage leading to cell death.2 The subcuta- neous tissue is the tissue with lowest blood perfusion, thus making it more susceptible to ischemia. A possible mechanism for the development of the traumatic ulcer could be: i) subcuta- neous adipose tissue cells die, due to the blunt trauma; ii) within the cell the osmotically active proteins are let loose themselves in the interstitium, drawing water to the area; iii) edema is created in the ageing skin the amount of collagen and elastin is reduced3 especially in women after menopause, leading to reduced forces to counteract the edema (intrinsic compression). As an edema has developed, the rationale for compression, with either bandages or stockings with high stiffness, seems obvious. The impressive healing rate of 25% per week (Table 1) supports this view. References 1. Hafner J, Nobbe S, Partsch H, et al.
