Initial Debridement of Dorsal Hand Abscesses in the Operating Room Does Not Improve Outcomes.

Background: Hand infections frequently involve the dorsal aspect of the hand and often develop secondary to some traumatic mechanism. Although Staphylococcus aureus is most commonly isolated, anaerobic and polymicrobial infections are not uncommon. To date, treatment is largely anecdotal, with some surgeons preferring a formal debridement in the operating room, while others opt for an initial debridement at the bedside. The goals of this study were to compare outcomes between treatment modalities and to identify the most common causative organisms. Methods: A 10-year retrospective chart review was conducted to identify adult patients who presented with a dorsal hand infection to a single, level 1, urban trauma center. Demographic data were collected as well as the abscess size, location, duration of symptoms, treatment administered, number of formal debridements, length of hospital stay, and complications. Results: The number of formal debridements was significantly less in the initial bedside debridement group (P < .01), as was the hospital length of stay (P < .01). There was no significant difference in hospital readmissions, complications, or infection due to methicillin-resistant Staphylococcus aureus. There was also no significant difference in abscess size, duration of symptoms, or demographic data including age, sex, comorbidities, intravenous drug use status, and immunocompromised status. Conclusions: An initial debridement of dorsal hand infections at the bedside is at least as effective as formal debridement in the operating room. This decreases number of formal debridements and days in the hospital, without any increase in complications. This permits safe, expeditious, and cost-effective treatment for this common condition.

Increasing Multidrug Antibiotic Resistance in MRSA Infections of the Hand: A 10-Year Analysis of Risk Factors.

Background: Methicillin-resistant Staphylococcus aureus (MRSA) is the most common pathogen isolated from hand abscesses. The purpose of this study was to understand trends and changes in longitudinal antibiotic resistance profiles and risk factors for these infections to better guide empiric treatment of hand infections. Methods: We performed a retrospective review of culture-positive hand infections over a 10-year period at an urban academic institution from 2005 to 2014. A subset of MRSA hand infections from 2013 to 2014 was then subanalyzed for risk factors for antibiotic resistance for antibiotics with increasing antibiotic resistance during this period. Results: MRSA grew in 46% of hand infections, with a decreasing incidence over the 10-year study period. However, in the same time period clindamycin and levofloxacin resistance increased from 7% to 31% and 12% to 56%, respectively. Risk factors for clindamycin resistance included nosocomial infections and a history of intravenous drug use and hepatitis C. Risk factors for levofloxacin resistance included a history of diabetes and a fever upon initial presentation. Conclusions: The incidence of multidrug resistance remains high, with growing resistance to clindamycin and levofloxacin. There remains a trend for increased clindamycin resistance for patients with history of intravenous drug use and nosocomial infections. Our findings indicate that clindamycin and levofloxacin should be avoided for empiric treatment for hand infections in patients with these risk factors.

Variation in the management of thoracolumbar trauma and postoperative infection.

STUDY DESIGN: Multinational survey of spine trauma surgeons. OBJECTIVES: To survey spine trauma surgeons, examine the variety of management practices for thoracolumbar fractures, and investigate the need for future areas of study. BACKGROUND: Attempts to develop a universal thoracolumbar classification system represent the first step in standardizing treatment of thoracolumbar injuries, but there is little consensus regarding diagnosis and management of these injuries. METHODS: A survey questionnaire regarding a fictional neurologically intact patient with a burst fracture was administered to 46 spine surgeons. The questionnaire consisted of 2 domains: management of thoracolumbar fractures and management of postoperative infection. Survey results were compiled and evaluated and consensus arbitrarily assumed when the majority of surgeons agreed on a single question answer. RESULTS: Although majority consensus was reached on most questions, the interobserver reliability was poor. Consensus was achieved that magnetic resonance imaging should be performed during initial imaging. The majority would also operate regardless of magnetic resonance imaging findings, and would not operate at night. The favored technique was a posterior approach with decompression. Percutaneous fusion was considered a viable option by the majority of surgeons. No consensus was reached regarding instrumentation levels or construct length. The majority would use posterolateral bone grafting, and would not remove instrumentation nor perform an anterior reconstruction. Consensus was reached that postoperative bracing is unnecessary. Regarding management of infection, consensus was reached to use intraoperative vancomycin powder but not culture the nares before surgery. The majority used a set time period for antibiotic treatment when a drain was required, and would not apply supplementary bone graft at the time of final debridement and closure. CONCLUSIONS: There is lack of consensus regarding the appropriate management of thoracolumbar fractures. In the future, multicenter prospective studies are necessary to establish guidelines for the management of thoracolumbar fractures.
