Free tissue transfer to the knee can be difficult due to limited options for reliable recipient vessels and vein grafts or arteriovenous loops may also be associated with an increased risk of flap failure. In this study, the authors describe our experience with creating proper recipient vessels for free flap reconstructions around the knee using the descending branch (DB) of the lateral circumflex femoral vessels (LCFV) or anterior tibial vessels (ATV). Three patients underwent free flap reconstruction of knee wounds secondary to trauma, prosthesis infection, and radiation therapy.

Few studies have evaluated how frailty contributes to outcomes in geriatric hand surgery patients. This study hypothesizes that geriatric patients scoring higher on the modified Frailty Index 5 (mFI-5) are at greater risk of postoperative complications following DRUF fixation.

We hypothesized that time to first ambulation, ambulation without an assistive device, chronic osteomyelitis, and delayed amputation were not affected by the time to soft tissue coverage in Gustilo IIIB and IIIC fractures at our institution.
Methods: We evaluated all patients treated for open tibia fractures at our institution from 2007 to 2017.
Background: End-to-side nerve transfer (ETSNT) for treatment of peripheral nerve injuries is controversial given the myriad anatomic locations, injury types, and indications. Efficacy of ETSNT remains debated. We hypothesized differences in age, sex, transfer location, and time to surgery influence outcomes.

Innovations in wound care, soft tissue coverage and surgical fixation techniques allow for improved functional outcomes in this patient population with highly morbid injuries. In this review, the principles of reconstruction of complex lower extremity traumatic wounds are outlined.

Substance abuse is pervasive in the American society, with 10% of the United States population using marijuana, up to 17% of patients undergoing upper-extremity surgery reporting chronic opioid use, and up to 20% of acute hand infections occurring secondary to intravenous drug use. It is common, therefore, for a hand surgeon to take care of a patient under the influence of nonprescription drugs. The range of abused substances is diverse, and the implications are profound.

Options for choosing the optimal donor site tissues are increased with the free-style technique. This reduces donor site morbidity while providing the same reconstructive success as traditional free skin flaps.

Background: Flap reconstruction of radiated pelvic oncologic defects decreases perineal wound-healing complications. How widely and how often reconstructions are performed, and how technical mastery and improved perioperative care has affected outcomes, is unknown. Our objective is to 1) provide a comprehensive evaluation of national trends in flap reconstruction of pelvic oncologic defects and 2) compare complications and length of stay (LOS) in patients with/without reconstruction.

Many methods of reconstruction have been described, but no procedure demonstrates clear superiority. New methods proposed use internal bracing (IB) with suture anchors and flat braided suture (FBS), alone or as an augmentation with tendon autograft for SL ligament injuries.

Because it is frequently resistant to apoptosis, exploiting autophagic cell death could offer a new treatment approach. We repurpose echinomycin, an antibiotic encapsulated within a syndecan-1 actively targeted nanoparticle, for treatment of pancreatic cancer.

With advancements in microsurgical technique and experience, face transplantation is becoming a clinical reality and acceptable procedure. Preparation of the maxillofacial skeleton and initial soft-tissue coverage for face transplant candidates is essential for optimizing the ultimate outcome by providing immediate coverage of vital structures, functionality, and a stable skeletal framework. We present our experience of preparing such a patient who underwent a successful face transplant, with an excellent outcome.

Standard MTT, ATPlite and protease assays that are used to determine the potency of newly developed drugs often give erroneous results when applied under hypoxic or acidic conditions. Therefore, development of a cytotoxicity assay that does not yield false positive or false negative results under circumstances of both hypoxia and acidic pH is needed.

Complex facial trauma requires complex repair and solutions. This process is challenging for the surgeon who seeks to manage the expectations of the patient and family while achieving the best possible result. Historically, the use of pedicled flaps, and then free tissue transfer, were the primary techniques utilized.

Methods: The American College of Surgeons National Surgical Quality Improvement Project (NSQIP) database was reviewed for reduction mammaplasty procedures from 2005 to 2017.
