Diabetic foot is one of the serious complications of diabetic patients. It is caused by diabetes combined with different degrees of lower extremity vascular lesions and neuropathy, and the wound can not heal for a long time. The serious results can cause bone marrow infection, bone destruction, and have high disability and death rate. At present, there are various treatment methods for diabetic foot chronic wound. On the basis of internal medicine controlling blood sugar, anti infection, lowering blood lipid, improving microcirculation and nourishment nerve, the surgical method is adopted, including the debridement of the necrosis in a short time to prevent the infection from spreading; maggot biological debridement and ozone chemical debridement will promote the growth of granulation tissue while controlling infection. Skin grafting, skin flap transplantation, skin distraction closure can be used to repair soft tissue defects, or fat transplantation, platelet-rich plasma, and rich blood are used for the refractory wound after infection control. In patients with diabetic foot, the reconstruction of lower limb blood supply is beneficial to the recovery of chronic ischemic wounds. It is feasible to improve the blood supply of the lower extremities, improve the blood supply of the lower extremity artery bypass grafting, and improve the microcirculation of the peripheral vessels around the lower extremities. Lower extremity vascular bypass pressure perfusion therapy for vascular network expansion, tibia lateral moving technique for lower limb microcirculation reconstruction. For diabetic foot ulcer caused by peripheral neuropathy, such as Charcot foot, while the application of external fixator, total contact cast technology of affected foot for reducing treatment to promote wound healing; the preparation of orthopedic shoes can play a maximum protective effect on the healing of diabetic foot wound healing.
ObjectiveTo evaluate the clinical value of skin stretching device in repair of diabetic foot wound.MethodsA retrospective analysis was made on the clinical data of 48 cases with diabetic foot wound who were treated with skin stretching device (trial group, n=24) and with the vacuum sealing drainage combined with skin graft (control group, n=24) respectively between October 2015 and July 2016. There was no significant difference in gender, age, side, course of disease, TEXAS stage between 2 groups (P>0.05). Both patients in 2 groups were treated with sensitive antibiotics according to the results of bacterial culture.ResultsOne case in control group was infected and the skin graft failed, and 1 case in trial group was infected after the treatment, and the two wounds healed after symptomatic treatment. The wounds of the other patients healed successfully, and the healing time of the trial group was significantly shorter than that of the control group [(12.8±11.6) days vs. (22.3±10.4) days; t=2.987, P=0.005). All patients were followed up 3-12 months after operation, and no wound dehiscence or recurrence occurred during follow-up.ConclusionCompared with the vacuum sealing drainage combined with skin graft, the application of skin stretching device in the repair of diabetic foot wound has advantages, such as easy to operate, shorten the wound healing time, and the appearance of wound was similar with the adjacent skin.
