We present a new technique for connecting open wounds to a negative-pressure device. In this technique, a flexible, small-diameter intravenous tube is used to bridge the gap between open wounds on the same extremity. After these connections are made, the first layer of plastic is placed, and only 1 fenestrated ...

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 ...

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 ...
