Functional Outcomes of Dorsal Bridge Plating for Lisfranc Injuries With Routine Implant Retention: A Major Trauma Center Experience.

OBJECTIVES: To assess medium-term functional outcomes and the complication profile for unstable Lisfranc injuries treated with dorsal bridge plate (DBP) fixation when implants are not routinely removed. DESIGN: Large single-center retrospective case series. SETTING: Level-1 Trauma Center, London, United Kingdom. PATIENTS: Consecutive cases of skeletally mature individuals with unstable Lisfranc injuries treated operatively between 2014 and 2019. INTERVENTION: Open reduction and DBP fixation with implants not routinely removed. MAIN OUTCOME MEASUREMENTS: Patient-reported outcome measures at final follow-up. The Manchester-Oxford Foot Questionnaire summary index was the primary outcome measure. The American Orthopaedic Foot and Ankle Society (AOFAS) midfoot scale, complications, and all-cause reoperation rates were secondary outcome measures. Logistic regression models were used to identify risk factors that influenced outcomes. RESULTS: Eighty-five patients were included. Mean follow-up was 40.8 months (24-72). The mean Manchester-Oxford Foot Questionnaire Summary Index was 27.0 (SD 7.1) and mean AOFAS score 72.6 (SD 11.6). The presence of an intra-articular fracture was associated with poorer outcomes, with worse MOXFQ and AOFAS scores (both P < 0.001). Eighteen patients (21%) required implants removal, with this more likely in female patients (OR 3.89, 95% confidence interval, 1.27 to 12.0, P = 0.02). Eight patients (9%) required secondary arthrodesis. CONCLUSIONS: This is the largest series of Lisfranc injuries treated with DBP fixation reported to-date and the only to routinely retain implants. Medium-term outcomes are comparable to existing literature in which implants are routinely removed. The presence of an intra-articular fracture is a poor prognostic indicator. Implant removal is more likely to be needed in female patients. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for authors for a complete description of levels of evidence.

Global impact of COVID-19 on surgeons and team members (GlobalCOST): a cross-sectional study.

OBJECTIVES: To investigate the impact of COVID-19 on the well-being of surgeons and allied health professionals as well as the support provided by their institutions. DESIGN: This cross-sectional study involved distributing an online survey through medical organisations, social media platforms and collaborators. SETTING: It included all staff based in an operating theatre environment around the world. PARTICIPANTS: 1590 complete responses were received from 54 countries between 15 July and 15 December 2020. The average age of participants was 30-40 years old, 64.9% were men and 32.5% of a white ethnic background. 79.5% were surgeons with the remainder being nurses, assistants, anaesthetists, operating department practitioners or classified other. MAIN OUTCOME MEASURES: Participants that had experienced any physical illness, changes in mental health, salary or time with family since the start of the pandemic as well as support available based on published recommendations. RESULTS: 32.0% reported becoming physically ill. This was more likely in those with reduced access to personal protective equipment (OR 4.62; CI 2.82 to 7.56; p<0.001) and regular breaks (OR 1.56; CI 1.18 to 2.06; p=0.002). Those with a decrease in salary (29.0%) were more likely to have an increase in anxiety (OR 1.50; CI 1.19 to 1.89; p=0.001) and depression (OR 1.84; CI 1.40 to 2.43; p<0.001) and those who spent less time with family (35.2%) were more likely to have an increase in depression (OR 1.74; CI 1.34 to 2.26; p<0.001). Only 36.0% had easy access to occupational health, 44.0% to mental health services, 16.5% to 24/7 rest facilities and 14.2% to 24/7 food and drink facilities. Fewer measures were available in countries with a low Human Development Index. CONCLUSIONS: This work has highlighted a need and strategies to improve conditions for the healthcare workforce, ultimately benefiting patient care.

Long-term functional outcomes following paediatric traumatic elbow dislocation, a clinical retrospective cohort study.

BACKGROUND: Paediatric traumatic elbow dislocation occurs in 6 per 100,000 children per year and if not treated promptly can result in a poor outcome. Despite this, the long-term clinical and functional outcome of these injuries has not been well described using modern patient-reported outcome tools. The aim of our study was present the outcome of these injuries in the long term. METHODS: Twenty children with an acute traumatic elbow dislocation who presented between February 2007 to February 2016 were included in our study. Patient demographics, management and complications were recorded from the clinical notes. Ten children had associated fractures and were managed surgically, while the remaining were managed with closed reduction and immobilisation. Functional outcomes were assessed with Kim's elbow performance score. RESULTS: The mean age was 12 years (7 -15) and follow-up was 8 years (4 - 13). There was one (5%) re-dislocation requiring surgery and one (5%) ulna nerve neurapraxia that resolved within one month. The average Kim's scores were 87.5 (65 - 100) and 77.5 (60 - 100) in the closed reduction and open reduction groups, respectively (P=0.08). 80% (16/20) reported good or excellent outcome with a Kim's score of greater than 75 points with no cases of poor functional outcome reported in our series. CONCLUSIONS: Traumatic elbow dislocations in children, with or without associated fracture, have a good long-term functional outcome with appropriate early management.

Outcomes of posterior malleolar fixation in ankle fractures in a major trauma centre.

AIMS: Ongoing controversy exists over the indications and benefits of posterior malleolar fixation in ankle fractures. The aim of this pragmatic study was to evaluate the outcomes of posterior malleolar fracture fixation in ankle fractures in the setting of a major trauma centre. Our hypothesis is that posterior malleolus fixation leads to improved clinical outcomes. METHODS: A total of 320 patients were identified with operatively treated ankle fractures involving a posterior malleolus component, at our institution between January 2012 and January 2018, ensuring a minimum 2 year follow-up. Of these patients, 160 had the posterior malleolus fixed as part of their surgery and 160 did not. Patient demographics, surgical details and complications were assessed. The Manchester-Oxford Foot Questionnaire (MOXFQ) was the primary patient outcome measure. RESULTS: Fixation of the posterior malleolus was associated with a statistically significant improvement in patient outcomes. Mean MOXFQ score in the unfixed posterior malleolus group was 24.03 (0 - 62), compared to 20.10 (0 - 67) in the fixed posterior malleolus group (p = 0.04). Outcomes were worse with increasing size of posterior malleolar fragment. Metalwork-related issues were higher in the posterior malleolus fixed group (24/160 (15%) versus 10/160 (6.2%)) and re-operation rate was double. CONCLUSION: This study demonstrates that in the practical setting of a major trauma unit, fixation of the posterior malleolar fracture leads to improved patient outcomes but with increased metalwork risks and reoperation rates.

Dialkylcarbamoyl Chloride Dressings in the Prevention of Surgical Site Infections after Nonimplant Vascular Surgery.

BACKGROUND: Dressings coated with dialkylcarbamoyl chloride (DACC) are highly hydrophobic and irreversibly bind multiple types of bacteria, trapping them in the dressing and reducing the number of organisms at the wound surface. We aimed to assess the impact of DACC-coated postoperative dressings on the incidence of surgical site infection (SSI) in nonimplant vascular surgery patients. METHODS: Two hundred patients undergoing nonimplant vascular surgery were prospectively recruited at a single vascular center. The initial 100 patients had their operative wounds dressed with conventional dressings followed by 100 patients who received DACC-coated postoperative dressings. Wounds were reviewed at day 5 and day 30 to determine the presence of SSI using the ASEPSIS scoring system. The variation in outcomes between groups was assessed using chi-squared test and logistic regression analysis to assess the effects of other variables, which may affect healing. RESULTS: Between August 1, 2015 and February 29, 2016, a total of 120 men and 80 women were recruited. The mean age was 63 (range 27-97) years, 92% were current or ex-smokers and 45.5% were diabetic. Rate of SSI at 5 days was significantly lower in the DACC group compared with standard dressings (1% vs. 10%, P < 0.05). There was no difference in the rates of SSI at 30 days. Logistic regression suggested that the type of dressing used was the most prominent predictor variable for the presence of early SSI (P = 0.028, odds ratio = 0.09, 95% confidence interval: 0.01-0.77). CONCLUSIONS: DACC-coated dressings were associated with a significant reduction in SSI rates in the early postoperative period.

Deepening Trochleoplasty With a Thick Osteochondral Flap for Patellar Instability: Clinical and Functional Outcomes at a Mean 6-Year Follow-up.

BACKGROUND: In patients with patellar instability and severe trochlear dysplasia, trochleoplasty has become increasingly used as part of its surgical management. HYPOTHESIS: Deepening trochleoplasty for severe dysplasia in patellofemoral instability improves function and increases sports participation. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Between 1995 and 2010, deepening trochleoplasty with a thick flap was performed in 90 patients (107 knees) with severe trochlear dysplasia. Data were collected prospectively preoperatively, at 6 weeks, and at 1-year follow-up. The patients were surveyed retrospectively to determine the clinical and functional outcomes including sports and exercise participation at a minimum of 2 years, with complete data available in 92%. RESULTS: The average follow-up was 6 years (range, 2-19 years). The median Kujala score was 63 (interquartile range [IQR], 47-75) preoperatively, rising to 79 (IQR, 68-91) at 1-year follow-up and 84 (IQR, 73-92) at final follow-up (P < .05). Seventy-two percent were satisfied with their knee function at 1-year follow-up, rising to 83% at final follow-up (P < .0001). Sports and exercise participation increased from 36 patients (40%) preoperatively to 60 (67%) at final follow-up. The number of patients involved in competitions increased slightly from 10 (11%) to 11 (12%). Of those sports that involved twisting (e.g., soccer, cricket, badminton), the number of patients participating increased from 16 (18%) to 22 (24%), whereas in nontwisting sports (e.g., running, swimming, cycling), it increased from 24 (27%) to 47 (52%), of whom 12 (16%) used walking as exercise. Two patients who had undergone medial patellofemoral ligament (MPFL) reconstruction as the index operation needed the MPFL revised, and a further 8 patients needed MPFL reconstruction subsequently for instability symptoms and a mediolateral glide in extension of more than 2 quadrants' displacement. At final follow-up, no patient had mechanical patellofemoral instability. CONCLUSION: Deepening trochleoplasty with a thick flap improves clinical and functional outcomes for patients with symptomatic patellar instability with severe trochlear dysplasia. These results improve over time and beyond 1-year clinical follow-up. However, trochleoplasty does not lead to a significant improvement in sports participation at a competitive level. It does improve patient participation in sports and exercise, principally in nontwisting sports activities.

Effect of medications with anti-cholinergic properties on cognitive function, delirium, physical function and mortality: a systematic review.

OBJECTIVES: to determine the effect of drugs with anti-cholinergic properties on relevant health outcomes. DESIGN: electronic published and unpublished literature/trial registries were systematically reviewed. Studies evaluating medications with anti-cholinergic activity on cognitive function, delirium, physical function or mortality were eligible. RESULTS: forty-six studies including 60,944 participants were included. Seventy-seven percent of included studies evaluating cognitive function (n = 33) reported a significant decline in cognitive ability with increasing anti-cholinergic load (P < 0.05). Four of five included studies reported no association with delirium and increasing anti-cholinergic drug load (P > 0.05). Five of the eight included studies reported a decline in physical function in users of anti-cholinergics (P < 0.05). Three of nine studies evaluating mortality reported that the use of drugs with anti-cholinergic properties was associated with a trend towards increased mortality, but this was not statistically significant. The methodological quality of the evidence-base ranged from poor to very good. CONCLUSION: medicines with anti-cholinergic properties have a significant adverse effect on cognitive and physical function, but limited evidence exists for delirium or mortality outcomes.
