Comparative StudyFree Functioning Gracilis Muscle Transfer versus Intercostal Nerve Transfer to Musculocutaneous Nerve for Restoration of Elbow Flexion after Traumatic Adult Brachial Pan-Plexus Injury.
After complete five-level root brachial plexus injury, free functional muscle transfer and intercostal nerve transfer to the musculocutaneous nerve are two potential reconstructive options for elbow flexion. The aim of this study was to determine the outcomes of free functional muscle transfer versus intercostal nerve-to-musculocutaneous nerve transfers with respect to strength. ⋯ Therapeutic, III.

Secondary lymphedema is a dreaded complication that sometimes occurs after treatment of malignancies. Management of lymphedema has historically focused on conservative measures, including physical therapy and compression garments. More recently, surgery has been used for the treatment of secondary lymphedema. ⋯ The medical and surgical treatments of lymphedema are safe and effective techniques to improve symptoms and improve quality of life in properly selected patients.

Necrotizing fasciitis is a serious soft-tissue infection associated with sepsis and tissue destruction. Surgical management usually requires extensive débridement of necrotic fascia and overlying skin, with significant aesthetic and functional consequences. The authors review the outcome of all recent cases of necrotizing fasciitis treated with skin-sparing débridement at their institution. ⋯ Therapeutic, IV.

A Porcine Orthotopic Forelimb Vascularized Composite Allotransplantation Model: Technical Considerations and Translational Implications.
The restoration of complex tissue deficits with vascularized composite allotransplantation is a paradigm shift in reconstructive surgery. Clinical adoption of vascularized composite allotransplantation is limited by the need for systemic immunosuppression, with associated morbidity and mortality. Small-animal models lack the biological fidelity and preclinical relevance to enable translation of immunologic insights to humans. Large-animal models have been described; however, limitations persist, including the inability of heterotopic models to evaluate functional nerve regeneration, and the sensitivity of primates to toxicity of immunosuppressive drugs. The authors' novel orthotopic porcine limb transplant model has broad applicability and translational relevance to both immunologic and functional outcomes after vascularized composite allotransplantation. ⋯ An orthotopic load-bearing porcine forelimb vascularized composite allotransplantation model was successfully established. Technical, procedural, and logistic considerations were optimized to allow model use for immunologic, bone healing, functional nerve regeneration, and other translational studies.
