Injectable Pore-Forming Hydrogel Scaffolds for Complex Wound Tissue Engineering: Designing and Controlling Their Porosity and Mechanical Properties.

Traumatic soft tissue wounds present a significant reconstructive challenge. The adoption of closed-circuit negative pressure wound therapy (NPWT) has enabled surgeons to temporize these wounds before reconstruction. Such systems use porous synthetic foam scaffolds as wound fillers at the interface between the negative pressure system and the wound bed.

Managing missed lower extremity compartment syndrome in the physiologically stable patient: A systematic review and lessons from a Level I trauma center.

Background: Decompressing an acute lower extremity compartment syndrome salvages muscle and nerve and preserves limb function. However, reperfusion of ischemic tissue causes a systemic insult that can be life threatening. Hence, the management of missed acute lower limb compartment syndrome remains controversial.

Modular and Versatile Spatial Functionalization of Tissue Engineering Scaffolds through Fiber-Initiated Controlled Radical Polymerization.

Native tissues are typically heterogeneous and hierarchically organized, and generating scaffolds that can mimic these properties is critical for tissue engineering applications. By uniquely combining controlled radical polymerization (CRP), end-functionalization of polymers, and advanced electrospinning techniques, a modular and versatile approach is introduced to generate scaffolds with spatially organized functionality. Poly-ε-caprolactone is end functionalized with either a polymerization-initiating group or a cell-binding peptide motif cyclic Arg-Gly-Asp-Ser (cRGDS), and are each sequentially electrospun to produce zonally discrete bilayers within a continuous fiber scaffold.

Experience of an orthoplastic limb salvage team after the Haiti earthquake: analysis of caseload and early outcomes.

Background: After the devastating earthquake in Haiti on January 12, 2010, a British orthoplastic limb salvage team was mobilized. The team operated in a suburb of Port-au-Prince from January 20, 2010. This analysis gives an overview of the caseload and early outcomes.

Prolongation of skin allograft survival after neonatal injection of donor bone marrow and epidermal cells.

Composite-tissue (e.g., hand allograft) allotransplantation is currently limited by the need for immunosuppression to prevent graft rejection.
