Sternal malunion, or loss, developed after a median sternotomy cannot only be difficult to manage and treat, but also may diminish one's quality-of-life drastically. The technique presented here represents a multispecialty approach in one stage for the reconstruction of an unstable thoracic cage. The procedure utilized a donated sternum and ribs. The sternum with ribs harvested from a single donor included adipose derived stromal vascular fraction (ADSVF) cells with marrow also from the same donor. Autologous muscle flaps, stabilized with acellular dermal matrix were utilized to provide a robust blood supply to the ADSVF cells and bone grafts. Acellular dermal matrix was used to construct the ribs and stabilize the plugs of stem cells and bone. These procedures, in the hands of multispecialty physicians, have led to several successful reconstructions involving complex chest wall deformities. This surgical intervention was performed in a one stage operation. This represents the first successful complete sternal transplant in a patient with return to normal activities and increased quality-of-life.

<P><B>Abstract</B></P> <P>A model of cesium (Cs) dynamics among the principal biotic and abiotic components of an 11.4-ha impoundment is described. The model is derived from analyses of field measurements of Cs-133 concentrations in pond components for 500 days following the addition of 4 kg of stable Cs-133 to the system. This study differs from similar experiments in which radionuclides, or their stable analogs have been added to small ponds in that the biomasses of key pond components were also obtained. The Cs-133 concentrations and biomasses were used to compute the dynamics of Cs-133 inventories and fluxes among the pond components. The model permits interesting comparisons of Cs-133 transport and fate over time among the pond's abiotic components, primary producers, and two-orders of consumers. The importance of the submerged macrophyte and periphyton community in controlling the transport and fate of the added Cs-133 is quantified. Macrophytes intercepted much of the Cs-133 and slowed its ultimate sequestration by the sediments. The macrophytes' rapid absorption and slow release of Cs-133 prolonged the availability of the element to other pond biota. These data are being used within a subsequent paper to further develop the model into one in which the Cs-133 kinetics are described by transfer coefficients so that effects of changing environmental variables and remediation options can be explored.</P> <P><B>Highlights</B></P> <P> <UL> <LI> “Tabular” model of inventories of <SUP>133</SUP>Cs (in mg) in main biotic components following the addition of 4 kg of Cs-133 to Pond 4. </LI> <LI> Models 8 biota: submerged macrophytes, plankton, periphyton, <I>Chaoborus</I> larva, snails, bluegills, lake chubs, and largemouth bass. </LI> <LI> The evaluation includes an assessment of the daily fluxes of Cs-133 amongst the biotic components. </LI> <LI> The flux of <SUP>133</SUP>Cs from the water → plankton → largemouth bass was 50X less than that of water → periphyton → largemouth bass. </LI> <LI> These inventory and flux data are developed to be utilized in a subsequent kinetic model characterized by transfer coefficients. </LI> </UL> </P>
