Information on surgical site infection (SSI) after surgical treatment of ankle fracture is limited and remains controversial. The purpose of the present study was to determine the incidence and risk factors for SSI after open reduction and internal fixation (ORIF) of ankle fracture. Patients who underwent ORIF for ankle fracture at 3 centers between January 2015 and December 2016 were included. The potential risk factors for SSI included demographic variables, including age, sex, body mass index (BMI), hypertension, diabetes mellitus, heart disease, smoking, and excessive alcohol intake; blood test variables including preoperative white blood cell count, neutrophil count, red blood cell count, hemoglobin, total protein, albumin and globulin; injury- and surgery-related variables, including duration of operation (minutes), intraoperative blood loss, surgeon level, fracture site, accompanied dislocation, use of a drainage tube, and antibiotic use. Factors related with SSI occurrence were investigated by univariate analysis, and then by multivariate analysis. During hospitalization, 4.37% (66/1511) of patients developed SSI, which was deep in 1.32% (20/1510) and superficial in 3.05% (46/1510). The most common causative agent was polymicrobial (causing approximately half of all SSIs), followed by methicillin-resistant Staphylococcus aureus (MRSA). Multivariate analysis revealed that the significant risk factors for SSI occurrence were open injury, advanced age, incision cleanliness II – IV, high-energy injury, more experienced surgeon level, greater BMI, chronic heart disease, history of allergy, and preoperative neutrophil count > 75%. Preoperative preventative measures should be taken in patients with these conditions to lower the incidence of SSI after ORIF of ankle fracture.LEVEL OF EVIDENCE: Level III - Retrospective Comparative Study.
Low- and middle-income countries contribute to only a small percentage of publications in multiple medical fields. Editorial bias was reported to be an important reason for this. However, whether this trend exists in leading spine journals remains unclear. This study determined the composition of the editorial boards of leading spine journals and analyzed the international representation of editorial boards. The editorial board members of four leading subspecialty spine journals, including The Spine Journal , Journal of Neurosurgery: Spine , European Spine Journal , and Spine were identified from the journals’ websites. The countries of editorial board members were identified and analyzed according to the continent and country income categories classified by the World Bank. A total of 608 editorial board members were identified from the four leading spine journals. The majority (91.4%) of editorial board members were from high-income countries, followed by upper-middle income countries (7.2%), and lower-middle income countries (1.3%). No editorial board members were from low-income countries. Regarding the continent of residence, 46.5% of the editorial board members were from North America, followed by Europe (38.5%), Asia (9.9%), South America (2.8%), Oceania (1.6%), and Africa (0.7%). The editorial board members came from 40 different countries, which were concentrated in North America, Western Europe, and East Asia. The largest number of editorial board members came from the United States (42.3%), followed by Germany (6.9%), the United Kingdom (6.7%), Switzerland (5.8%), and Italy (5.1%). A lack of international representation on editorial boards exists in leading spine journals. Editorial board members from high-income countries are substantially overrepresented, while editorial board members from low- and middle-income countries are severely underrepresented. The United States is the most represented country on the editorial boards of leading spine journals.
Information on ankle fractures is limited. The purpose of this study was to investigate the incidence and risk factors for deep surgical site infection (DSSI) after open reduction and internal fixation (ORIF). Adult patients who underwent ORIF for an ankle fractures at 3 level-I centres between January 2013 and June 2017 were included. Data on demographic, injury-related, and surgery-related variables and biochemical indexes from the laboratory were collected from patients' electronic medical records. Univariate analysis and multivariate logistic regression analysis model were used to perform the data analysis through SPSS 19.0. Within 1-year postoperatively, 2.83% (74/2617) of cases developed DSSI, with the earliest occurring at the 4th and latest at 147th day. Pseudomonas aeruginosa, methicillin-resistant Staphylococcus aureus, and methicillin-susceptible Staphylococcus aureus were the top 3 bacteria, causing 73% (37/51) of all the cases. Age (45-64 and ≥65 years), current smoking status, chronic heart disease, lower preoperative albumin level, open injury, and prolonged surgical duration were identified to be independently associated with DSSI occurrence. Preoperative active supplementation of nutrition, immediate smoking cessation, and optimisation of an operative plan for the reduction of surgical duration were feasible measures for DSSI prevention following ORIF of ankle fractures.
