BACKGROUND: Changes in compartment pressures have been noted during traction, reduction, and intramedullary fixation of fractures. Changes in limb length and compartment volumes are suspected contributing factors. Pressure and volume changes are known to be related in animal models. If an acute increase in limb length can adversely affect compartment ...

BACKGROUND: Increased intramedullary pressure in the femoral cavity causes intravasation of bone marrow content to the circulation which may lead to occlusion of pulmonary vessels and cardiorespiratory dysfunction. A one-step reamer-irrigator-aspirator (RIA) technique has been developed to reduce the intramedullary pressure (IMP) during the reaming procedure. This study was design ...

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.

A tremendous amount of research has been conducted in recent years investigating the mechanisms of action by which the application of subatmospheric pressure to wounds increases the rate of healing. Similarly, numerous studies have also been conducted examining the physiologic response of wounds to the applied subatmospheric pressure. However, many ...

Although reamed intramedullary nailing has been one of the greatest advances in modern fracture care, the concomitant increase in medullary cavity pressure leads to intravasation of bone marrow content into the blood stream, an effect that can evoke serious systemic reactions. A newly developed rinsing-suction-reamer (RSR) was able to substantially ...

To reduce pressure-related injuries resulting from pneumatic tourniquet use, the lowest possible inflation pressure is recommended. Arterial occlusion pressure (AOP) is a measure of the cuff pressure required to maintain a bloodless surgical field. However, its determination method is time consuming, requires operator skill, and is therefore seldom used in ...

Longevity of cemented femoral components is dependent upon many factors. It is certainly related to the cementing technique. A dilemma exists between adequate cement pressurization and risk of embolic events. A cementation pressure above bleeding pressure, to allow optimum cement bone interdigitation but not high enough to produce embolic or ...

Although 5-aminolevulinic acid, ALA, and its derivatives, have been widely studied and applied in clinical photodynamic therapy (PDT), there is still a lack of reliable and non-invasive methods and technologies to evaluate physiological parameters of relevance for the therapy, such as erythema, melanogenesis, and oxygen level. We have investigated the ...

Adequate cement pressurization during stem insertion improves the interdigitation of cement into bone. This increases the strength of the cement-bone interface, thus contributing to the reduction of the incidence of aseptic loosening, the commonest cause of revision surgery. This in-vitro study compared the cement pressurization achieved during insertion of four ...

Acute compartment syndrome is a potentially devastating condition in which the pressure within an osseofascial compartment rises to a level that decreases the perfusion gradient across tissue capillary beds, leading to cellular anoxia, muscle ischemia, and death. A variety of injuries and medical conditions may initiate acute compartment syndrome, including ...
