Despite almost 50 years of research on the functional morphology and biomechanics of suction feeding, no consensus has emerged on how to characterize suction-feeding performance, or its morphological basis. We argue that this lack of unity in the literature is due to an unusually indirect and complex linkage between the ...

Acute limb compartment syndrome (LCS) is a limb-threatening and occasionally life-threatening condition caused by bleeding or edema in a closed muscle compartment surrounded by fascia and bone, which leads to muscle and nerve ischemia. Well-known causative factors are acute trauma and reperfusion after treatment for acute arterial obstruction. Untreated compartment ...

Cement restrictors rely on achieving an interference fit with the wall of the medullary canal. Depending on the design of the cement restrictor, the intramedullary fit may be compromised as the femur starts to widen distally. Three different designs of cement restrictor were identified; universal, press-fit, and expandable. We determined ...

Complex pilonidal disease, an uncommon manifestation of an anorectal condition, is characterized by chronic or recurrent abscesses with extensive, branching sinus tracts. Definitive treatment requires wide excision of all involved tissue followed by secondary intention healing or reconstructive surgery. All treatment options have unique advantages and disadvantages. Following recent reports ...

V.A.C. Therapy applied to a cutaneous wound was hypothesized to alter vascular regulation in underlying tissue. Two full-thickness wounds were created on the dorsum of 7 New Zealand albino rabbits. One site was treated with V.A.C. Therapy; the other, with saline-moistened gauze. Local perfusion levels in the muscle were measured ...

The electrostrictive effects in anisotropic tissue, such as muscle, are interesting and qualitatively different than in an isotropic material. A striking feature in anisotropic tissue is the presence of a charge distribution, which is absent in isotropic tissue. This charge interacts with the electric field to give rise to body ...

Selecting the "ideal dressing" for a wound is based on considerations of specific factors, including presence of necrotic tissue, bacterial load, volume of exudate, and the need for a bacterial barrier. Many dressings are now available, including hydrocellular foam dressings, that possess multiple characteristics of the ideal dressing. This article ...

Wounds due to pressure arise in areas of anoxic necrosis. Blood is excluded from the skin by pressures in excess of the mean capillary pressure. In addition, trauma initiates haemostatic mechanisms which increase the extent of the vascular occlusion owing to the fact that endothelial cell retraction occurs and platelet ...

We used negative-pressure dressings to treat a poorly healing cervical rotation flap following radical neck dissection in an elderly man. The wound had failed to heal properly after 2 weeks of conservative management. Following application of the negative-pressure dressings, the wound granulated quickly and healed well by secondary intention.
