Case ReportsAdvanced MR neurography imaging of radial nerve entrapment at the spiral groove: a case report.
High-resolution magnetic resonance neurography (MRN) is being increasingly employed for the evaluation of peripheral nerves. We describe a case of spiral groove syndrome (Saturday night palsy) and illustrate the role of advanced 3 Tesla MRN imaging techniques, including three-dimensional diffusion-weighted fat-suppressed reversed fast imaging with steady-state precession and diffusion tensor imaging.

Major burn injuries can be devastating for the patients and their carers both in terms of morbidity and mortality. Therefore, it is important to optimize the treatment of the injured patient. After initial resuscitation and physiological stabilization, thorough surgical débridement of the burn is necessary. ⋯ However, in a small percentage of cases free flap surgery is necessary. Free tissue transfer in burns surgery is rare, but is indicated in those patients in which there is loss of a vascularized surface suitable for grafting such as exposed tendon, or bone following surgical débridement, and in extreme cases for limb salvage. This review article discusses the rationale for free flap surgery in terms of types of burn injuries, perioperative considerations, and summarizes the literature in free tissue transfer in acute burns.

Case ReportsAcellular dermal matrix and negative pressure wound therapy: a tissue-engineered alternative to free tissue transfer in the compromised host.
Free tissue transfer has revolutionized lower extremity reconstruction; however, its use in elderly patients with multiple medical problems can be associated with elevated rate s of perioperative morbidity and mortality. This study evaluates the use of acellular dermal matrix (ADM) in conjunction with negative pressure wound therapy (NPWT) and delayed skin graft application as an alternative to free tissue transfer in this compromised population. Bilayer, ADM (Integra, Plainsboro, NJ) was used in conjunction with NPWT (Wound V. ⋯ Definitive closure with split-thickness skin graft was achieved in three patients and one wound healed by secondary intention. No medical or surgical complications were encountered and stable soft tissue coverage was achieved in all patients. This early experience suggests that dermal substitute and NPWT with delayed skin graft application can provide a reasonable tissue-engineered alternative to free tissue transfer in the medically compromised individual.

ReviewThe impact of current immunosuppression strategies in renal transplantation on the field of reconstructive transplantation.
Composite tissue allograft (CTA) transplantation, such as the clinical face and hand transplants, has now been performed in multiple centers across the world. The transplants have successfully treated complex injuries that have either failed conventional approaches or where autologous reconstruction could not restore both form and function. CTA transplantation has the potential to improve outcomes over traditional techniques. ⋯ Due to the small numbers of CTA transplants performed, any modification in the immunosuppression used will likely be based from the solid organ literature. The renal transplantation literature has served as the basis for the current selection of CTA drug regimens and in this article we review the evidence in the renal transplant literature for the selection of immunosuppressive regimens. The study then compares the regimens used in both the face and hand transplantation with those regimens currently used for renal transplantation.

The first clinical face allotransplantation was performed by Devauchelle et al in 2005, and currently 13 facial allotransplantations have been performed worldwide. Reports on almost half of the cases were published in the literature, focusing on technical details of facial allograft inset to the recipient face. ⋯ Based on our experience with the first case of face transplantation, we describe the sequence of facial graft procurement from the human donor and compare similarities and differences between our case and previously published cases. Furthermore, we discuss different methods of restoration of the donor face and have outlined proposed guidelines for the sequence of donor operation for facial graft procurement.
