An orthopedic walking boot promotes rapid healing of diabetic foot ulcerations by lowering the maximum peak pressure imposed upon the foot. The walker has a hard unyielding shell which is designed for walking. The shell closely and rigidly supports a mid-sole in a foot-shaped bed. The mid-sole has a foot-shaped cavity with rounded sides adapted to form resilient support for the heel, arch and sides of a foot in addition to the bottom of a foot. A conformable inner-sole is adapted to fit over the foot-shaped cavity in the mid-sole and be compressed in response to foot pressure between the sides and bottom of the foot and the sides and bottom of the foot-shaped cavity in the mid-sole thereby compensating for small differences between the shape of the foot and the shape of the cavity. Weight applied to the foot is transferred to the walking shell by contact between the sides of the foot, arch, and heel and the arch, heel and sides of the foot-shaped cavity as well as the bottom of the cavity thereby decreasing the peak or maximum unit pressure on the plantar surface of the foot. A breathable bootie which wraps the foot and lower leg in a protective “cocoon” is preferably secured to the upper surface of the insole thereby preventing foreign materials from entering the foot cavity.

An electrosurgical method for treating foot ulcer, including diabetic foot ulcer, comprising: positioning an active electrode in close proximity to the ulcer, the active electrode being disposed on a distal end of an electrosurgical shaft; applying a high-frequency voltage potential difference across the active electrode and a return electrode in the presence of an electrically conductive fluid, the voltage potential being sufficient to generate plasma at the active electrode; and stimulating the ulcer with the active electrode to increase blood flow, remove unhealthy tissue and induce the body's natural healing response.

The invention relates to a wound dressing with high moisture absorption and a preparation method and an application thereof. The wound dressing comprises a bottom layer formed by non-sol fibers and a stuffed layer formed by sol fibers, wherein the sol fibers are woven on the bottom layer through a weaving mode and have the free stuffed length of 1-100mm, preferably 5-50mm. The wound dressing can be used for nursing chronic wounds such as venous stasis ulcers, pressure ulcer, diabetic foot ulcer and other chronic ulcer wounds comprising hole type or recessed type ulcer wounds.

The invention relates to the use of Epidermal Growth Factor (EGF) in a preferably-injectable pharmaceutical composition which is administered by means of infiltration into and around chronic cutaneous ischaemic lesions in order to prevent diabetic foot amputation. Said composition can be administered to recently-created surgical surfaces damaged by the effect of acute reperfusion with oxygenated blood following prolonged ischaemia, thereby preventing further surgical procedures and favouring the preservation of the extremity. The aforementioned composition can be used to improve (i) the cell microenvironment, thereby increasing the reparative and defensive capacity and viability of the is tissues and (ii) the cicatrisation of cutaneous ischaemic lesions, thereby stimulating cell proliferation. The invention is suitable for use in human, veterinary and experimental medicine, specifically in vascular angiology and surgery, dermatology, burn treatment and reconstructive surgery and geriatric medicine. Said composition can be used for recalcitrant ulcers which are associated with lesions in the macro and / or microvasculature, patients with inadequate lymphatic and / or venous return and ulcers or other lesions which are difficult to cicatrise and / or heal.

Epidermal growth factor (EGF) produced by an excretory recombinant approach was tested for its efficacy in treating various skin wounds. In a randomized double blind controlled study, local cream samples prepared with human EGF at a final concentration of as low as 0.02% (g / g) in topically suitable carrier were found to have an enhancing effect on the recovery of diabetes foot ulcers. This promotional effect is statistically significant and has resulted in a reduced mean healing time of over 3 weeks when compared with that of control. Both the 0.02% (g / g) and 0.04% (g / g) human EGF supplemented samples in comparison with control showed a trend of stimulatory effect when a recovery of 50% of an ulcer was considered. The EGF samples were also shown to be highly effective in promoting treatments of wounds resulting from bedsores and surgeries.
