Background There is a high incidence of hand and wrist injuries in athletes participating in collegiate sports, but there is little information published characterizing them. Purpose To characterize hand and wrist injuries in collegiate athletes using a large national database. Study Design Descriptive epidemiology study. Methods This retrospect...
Article
The purpose of this research was to evaluate a novel long-acting bupivacaine delivery system for control of postoperative pain. Bupivacaine-loaded lipid emulsion (BLE) droplets were created by high-speed homogenization. The BLE droplets were then entrapped into a crosslinked-hyaluronic acid hydrogel system to create an injectable composite gel form...

Background:. Both the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) and the American Society of Plastic Surgeons Tracking Operations and Outcomes for Plastic Surgeons (TOPS) databases track 30-day outcomes. Methods:. Using the 2008–2016 TOPS and NSQIP databases, we compared patient characteristics and postoperat...
Article
Background: In 2011, the Accreditation Council for Graduate Medical Education (ACGME) instituted further duty hour restrictions in response to concerns over long work hours and sleep deprivation in trainees and their effects on patient outcomes. The effect of duty hour restrictions on complications after breast reconstruction procedures has not be...
Article
Background: Research is a vital component of a plastic surgery residency. Residents participating in research are better able to critically evaluate literature, allowing them to stay current throughout their careers. Programs benefit from increased research by increasing their academic reputation and attracting stronger applicants. To discuss ongo...
Article
Background: Lower extremity free flaps are a common way to treat both traumatic and oncologic lower extremity wounds. These patients often suffer postoperative complications. We sought to use the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database to identify variables associated with postoperative compl...
Article
Background Bilateral mastectomy rates are increasing in the United States. The abdomen is the most common harvest site for autologous reconstruction. Nationwide data were examined to determine differences in hospital charges, length of stay (LOS), and early postoperative complications following immediate bilateral pedicled transverse rectus abdomin...
Article
Background: Males represent a significant portion of patients undergoing abdominal contouring. Despite this, there are few studies examining the implication of gender on complications. Objective: The aim of this study was to examine the association between gender and early postoperative outcomes in patients undergoing abdominal contouring proced...
Article
Background: Use of biological implants such as acellular dermal matrices in tissue expander breast reconstruction is a common adjunct to submuscular implant placement. There is a paucity of published prospective studies involving acellular matrices. The authors sought to evaluate a porcine-derived acellular peritoneal matrix product for immediate b...
Article
Background: Breast reduction is one of the most common procedures performed by plastic surgeons. Despite good outcomes and high patient satisfaction, there are little national data on the predictors that lead to complications in this patient population. We accessed a national outcomes database to examine these factors. Methods: This is a retrosp...

Leukocyte adhesion deficiency (LAD) is a rare primary immunodeficiency characterized by impairment of leukocyte migration during an inflammatory response. LAD patients can experience recurrent neutrophilic wounds similar to pyoderma gangrenosum (PG), predominantly of the skin and mucosal surfaces. There have been only a few reports addressing the m...

Article
Background The abdomen is the most common area from which tissue is harvested for autologous breast reconstruction. We sought to examine national data to determine the differences in total hospital charges, length of stay (LOS), and early postoperative complications following pedicled transverse rectus abdominis myocutaneous flap (pTRAM), free TRAM...

The surgical management of midface hypoplasia in the setting of Nager syndrome remains a significant challenge for craniofacial surgeons. This study describes a novel technique using distraction osteogenesis and modified osteotomies for the treatment of midface bony defects in an 11-year-old child with Nager syndrome. Presurgical 3-dimensional plan...
Article
Objective:: The current review and survey aim to assess the effectiveness of acellular dermal matrix (ADM) in the repair of cleft palate and oronasal fistula and to evaluate the current trends of ADM use in palate surgery. Design:: A systematic review of English articles was conducted using MEDLINE (1960 to July 1, 2016), the Cochrane Controlled...
Article
Background: The treatment of infected or exposed cardiac pacing and defibrillator devices is controversial. The conservative and widely accepted management calls for removal of the device and leads with immediate or delayed replacement of new components in a new site. Lead extraction carries a 2% major complication risk. In this article, we descri...
Article
Objective: To describe characteristics of dog bites and their treatment in a pediatric population including infection, medical specialties involved, rates of admission, and need for surgery. Method: Patients presenting with a dog bite to the emergency department of a tertiary care pediatric hospital between January 1, 2015, and June 30, 2017, we...
Article
Background: Early infectious flexor tenosynovitis has been treated with urgent surgery by most surgeons since Bunnell wrote the first textbook of hand surgery in 1945. Some surgeons have good experience with non-surgical management of early presenting disease in some cases. Methods: This retrospective chart review included 12 inpatients with ear...

The National Inpatient Sample database was used to examine the outcomes and cost associated with both pedicled and free tissue transfer from the abdomen in unilateral immediate breast reconstruction after mastectomy.
Article
Background: Despite high expenditure, there is little national data on rates of complications following pressure ulcer repair. Complications, mortality and their predictors following surgical repair of pressure ulcers were evaluated. Methods: Patients undergoing pressure ulcer repair were identified in the NSQIP database from 2005 to 2015. Regre...

Sagittal craniosynostosis remains the most common type of isolated craniosynostosis, accounting for nearly half of all nonsyndromic cases. The clinical diagnosis is typically made on the basis of a scaphocephalic head shape and is confirmed by computed tomography or magnetic resonance imaging. The current review examines the major surgical options...
