RESUMEN
BACKGROUND: In the postoperative period, clinically feasible instruments to monitor elderly patients' neurocognitive recovery and discharge-readiness, especially after short-stay procedures, are limited. Cognitive monitoring may be improved by a novel digital clock drawing test (dCDT). We screened for cognitive impairment with the 4 A Test (4AT) and then administered the dCDT pre and post short-stay procedure (endoscopy). The primary aim was to investigate whether the dCDT was sensitive to a change in cognitive status postendoscopy. We also investigated if preoperative cognitive status impacted postendoscopy dCDT variables. METHODS: We recruited 100 patients ≥65 years presenting for endoscopy day procedures at a single metropolitan hospital. Participants were assessed after admission and immediately before discharge from the hospital. We administered the 4AT, followed by both command and copy clock conditions of the dCDT. We analysed the total drawing time (dCDT time), as well as scored the drawn clock against the established Montreal Cognitive Assessment (MoCA) criteria both before and after endoscopy. RESULTS: Linear regression showed higher 4AT test scores (poorer performance) were associated with longer postoperative dCDT time (ß = 5.6, p = 0.012) for the command condition after adjusting for preoperative baseline dCDT metrics, sex, age, and years of education. CONCLUSION: Postoperative dCDT time-based variables slowed in those with baseline cognitive impairment detected by the 4AT, but not for those without cognitive impairment. Our results suggest the dCDT, using the command mode, may help detect cognitive impairment in patients aged >65 years after elective endoscopy.

In December 2019, New Jersey became one of the first states to have its industrial hemp (Cannabis sativa L.) plan approved by the U.S. Department of Agriculture (USDA) following enactment of the 2018 Farm Bill that authorized the production of hemp. Following this approval, hemp was legally grown for the first time in 2020. During the growing seasons of 2020 and 2021, powdery mildew-like symptoms were observed during the summer months (Jun to Aug) in greenhouse hemp research and fall months (Aug to Oct) in field production plots on Rutgers Agricultural Experiment Station farms in southern and northern New Jersey. Symptoms were observed on leaves and stems of hemp cultivars 'CB Genius', 'Cherry Wine' and 'Bay Mist'. Symptoms initially appeared as small white patches of mycelia and conidia on the adaxial surface of leaves that gradually spread to entire leaves and stems. Leaf discoloration (e.g., chlorosis) and premature leaf drop were observed. More severe symptoms and damage were observed in the greenhouse than outdoor cultivation. A voucher specimen was deposited in the U.S National Fungus Collections, USDA-ARS, Beltsville, MD (accession number 929187). Morphological examination of the white colonies from the cultivar 'Baymist' was carried out using light microscopy and further characterized by sequencing. This isolate was labelled PMH2. Hyphae were septate, conidiophores were hyaline, unbranched, measuring 130 to 240 µm in length and produced 1 to 4 conidia in chains. Conidia were hyaline, ellipsoid to ovoid in shape and measured 20 to 36 ×10 to 18 µm (n=30). Oil-like drops were present within conidia, although no distinct fibrosin bodies were observed. Chasmothecia were not observed. Morphological observations were consistent with those of Golovinomyces spp. as described by Braun and Cook (2012). Morphological observations (conidiophore and conidial measurements) were also similar to the description of G. ambrosiae on Hemp, as described in Wiseman et al, 2021. Sequencing of internal transcribed spacer (ITS), large ribosomal subunit (28S), intergenic spacer (IGS), beta- tubulin (TUB2) and chitin synthase 1(CHS1) region, were carried out with the primer sets ITS5/ITS4, LSU1/LSU2, IGS-12a/NS1R, TubF1/TubR1 and gCS1a1/gCS1b respectively, as shown by Qiu et al. (2020). Maximum-likelihood phylogenetic analysis confirmed the grouping of the PMH2 isolate within the G. ambrosiae accessions. Each individual gene alignment was treated as a separate partition. Sequences were not concatenated for maximum -likelihood phylogenetic analysis. Sequence data were deposited in GenBank under the accessions OK626453 (ITS), OK626454 (28S), OL456201 (IGS), OL415512 (TUB2) and OL415513(CHS1). To fulfill Koch's postulates, two mature, potted plants of C. sativa cv. 'Alpha Explorer' were inoculated by gently pressing symptomatic hemp leaves onto their leaf surface. They were incubated in an indoor grow room at 23°C and relative humidity of 50%. Non-inoculated healthy plants of C. sativa cv. 'Alpha Explorer' served as control. Inoculated plants developed powdery mildew symptoms within 10 to 12 days, while all control plants were asymptomatic. The powdery mildew on inoculated plants was found to be morphologically similar to the original. G. ambrosiae has been reported on C.sativa in Oregon (Wiseman et al. 2021) and G. ambrosiae (as G. spadiceus) has been reported on Cannabis in Kentucky (Szarka et al. 2019), Ohio (Farinas and Hand 2020) and New York (Weldon et al. 2020). This is the first known report of Golovinomyces ambrosiae causing powdery mildew on hemp in New Jersey. With the recent opening ( Dec15, 2021) of cultivation licensing and retailing of recreational marijuana, the acreage of Hemp production in New Jersey is expected to significantly increase, particularly for greenhouse production. It is important to document the species to develop management strategies to control this disease.
RESUMEN
BACKGROUND: We developed a digital clock drawing test (dCDT), an adaptation of the original pen and paper clock test, that may be advantageous over previous dCDTs in the perioperative environment. We trialed our dCDT on a tablet device in the preoperative period to determine the feasibility of administration in this setting. To assess the clinical utility of this test, we examined the relationship between the performance on the test and compared derived digital clock measures with the 4 A's Test (4AT), a delirium and cognition screening tool. METHODS: We recruited a sample of 102 adults aged 65 years and over presenting for elective surgery in a single tertiary hospital. Participants completed the 4AT, followed by both command and copy clock conditions of the dCDT. We recorded time-based clock-drawing metrics, alongside clock replications scored using the Montreal Cognitive Assessment (MoCA) clock scoring criteria. RESULTS: The dCDT had an acceptance rate of 99%. After controlling for demographic variables and prior tablet use, regression analyses showed higher 4AT scores were associated with greater dCDT time (seconds) for both command (ß = 8.2, P = .020) and copy clocks (ß = 12, P = .005) and lower MoCA-based clock scores in both command (OR = 0.19, P = .001) and copy conditions (OR = 0.14, P = .012). CONCLUSION: The digital clock drawing test is feasible to administer and is highly acceptable to older adults in a preoperative setting. We demonstrated a significant association between both the dCDT time and clock score metrics, with the established 4AT. Our results provide convergent validity of the dCDT in the preoperative setting.
RESUMEN
Background: Venous thromboembolism (VTE) is the second most common complication after hip fracture surgery. We used thrombelastography (TEG), a whole-blood, point-of-care test that can provide an overview of the clotting process, to determine the duration of hypercoagulability after hip fracture surgery. Methods: In this prospective study, consecutive patients aged 51 years or more with hip fractures (trochanteric region or neck) amenable to surgical treatment who presented to the emergency department were eligible for enrolment. Thrombelastography, including calculation of the coagulation index (CI) (combination of 4 TEG parameters for an overall assessment of coagulation) was performed daily from admission until 5 days postoperatively, and at 2 and 6 weeks postoperatively. All patients received 28 days of thromboprophylaxis. We used single-sample t tests to compare mean maximal amplitude (MA) values (a measure of clot strength) to the hypercoagulable threshold of greater than 65 mm, a predictor of in-hospital VTE. Results: Of the 35 patients enrolled, 11 (31%) were hypercoagulable on admission based on an MA value greater than 65 mm, and 29 (83%) were hypercoagulable based on a CI value greater than 3.0; the corresponding values at 6 weeks were 23 (66%) and 34 (97%). All patients had an MA value greater than 65 mm at 2 weeks. Patients demonstrated normal coagulation on admission (mean MA value 62.2 mm [standard deviation (SD) 6.3 mm], p = 0.01) but became significantly hypercoagulable at 2 weeks (mean 71.6 mm [SD 2.6 mm], p < 0.001). There was a trend toward persistent hypercoagulability at 6 weeks (mean MA value 66.2 mm [SD 3.8 mm], p = 0.06). Conclusion: More than 50% of patients remained hypercoagulable 6 weeks after fracture despite thromboprophylaxis. Thrombelastography MA thresholds or a change in MA over time may help predict VTE risk; however, further study is needed.
Contexte: La thromboembolie veineuse (TEV) est la deuxième complication la plus courante après une chirurgie pour fracture de la hanche. Nous avons eu recours à la thromboélastographie, un test de sang total effectué au point d'intervention et donnant une idée du processus de coagulation, pour évaluer la durée de l'hypercoagulabilité à la suite d'une chirurgie pour fracture de la hanche. Méthodes: Cette étude prospective a été menée auprès de patients consécutifs admissibles de 51 ans et plus qui se sont présentés à l'urgence pour une fracture de la hanche (région trochantérienne ou col du fémur) pouvant faire l'objet d'un traitement chirurgical. Une thromboélastographie (TEG), qui comprenait le calcul de l'indice de coagulation (IC) [combinaison de 4 paramètres du TEG permettant une évaluation globale de la coagulation], a été réalisée chaque jour, de l'admission au cinquième jour postopératoire, de même qu'à 2 et à 6 semaines postopératoires. Tous les patients ont suivi une thromboprophylaxie de 28 jours. Nous avons réalisé des tests t pour échantillon unique afin de comparer l'amplitude maximale (AM) moyenne (une mesure de la résistance d'un caillot) au seuil d'hypercoagulabilité de plus de 65 mm, un prédicteur de TEV à l'hôpital. Résultats: Des 35 patients recrutés, 11 (31 %) présentaient une hypercoagulabilité à l'admission selon une AM supérieure à 65 mm, et 29 (83 %) présentaient une hypercoagulabilité selon un IC supérieur à 3,0; les valeurs correspondantes à 6 semaines étaient de 23 (66 %) et de 34 (97 %), respectivement. Tous les patients avaient une AM de plus de 65 mm à 2 semaines. Dans l'ensemble, les patients avaient une coagulation normale à l'admission (AM moyenne 62,2 mm [écart type (E.T.) 6,3 mm], p = 0,01), mais présentaient une hypercoagulabilité importante à 2 semaines (moyenne 71,6 mm [E.T. 2,6 mm], p < 0,001). L'hypercoagulabilité avait tendance à persister à 6 semaines (AM moyenne 66,2 mm [E.T. 3,8 mm], p = 0,06). Conclusion: Malgré la thromboprophylaxie, plus de 50 % des patients présentaient toujours une hypercoagulabilité 6 semaines après leur fracture. Les seuils d'AM à la thromboélastographie et les changements de l'AM au fil du temps pourraient aider à prédire le risque de TEV, mais d'autres études sur le sujet sont nécessaires.

PURPOSE: This trial was conducted to determine the medium-term functional outcome of displaced tibial plateau fracture patients treated with closed fluoroscopic assisted reduction and internal fixation (CRIF) versus patients treated with standard open reduction with sub-meniscal arthrotomy and internal fixation (ORIF). METHODS: A prospective trial was conducted in adult patients with displaced AO/OTA 41 B and 41 C tibial plateau fractures. Patients were assigned to treatment based upon the standard treatment of the surgeon involved following the call schedule for the day, either CRIF or ORIF. Postoperative radiographs and CT were performed on all patients and patients were followed for a minimum of 2 years. Primary outcome measures were the KOOS, SMFA and SF-36. RESULTS: Seventy patients were recruited with 2 year follow-up on 35 patients in the CRIF group and 27 patients in the ORIF group. Postoperative CT scans showed that reductions were better with the ORIF group especially in the posterolateral quadrant as compared to the CRIF group. The frequency of mal-reductions was higher in the CRIF group. The KOOS, at two years, showed that the CRIF had significantly less good outcomes in the subcategories of SPORT (p = 0.03) and QOL (p = 0.01) measurements. CONCLUSIONS: ORIF with a sub-meniscal arthrotomy provides better quality reductions and better medium-term results as compared to CRIF for tibial plateau fractures. This may provide more long-term benefit from osteoarthritic symptoms in this patient group. LEVEL OF EVIDENCE: Therapeutic, Level 2.

BACKGROUND: Despite its use in the literature, the application of the Herscovici classification system for medial malleolus fractures has not been evaluated. METHODS: We aimed to determine the reliability and accuracy of the Herscovici classification. The blinded radiographs of 130 patients were independently classified by four orthopaedic trauma surgeons. We held a consensus meeting where observers agreed on a final classification and this served as our reference standard. We used weighted kappa (κ) coefficients of agreement. RESULTS: Twenty-four fractures (18%) were deemed unclassifiable. The classification system demonstrated moderate inter-observer reliability (κ=0.54, 95% CI 0.40-0.68) but substantial reproducibility (κ=0.64, 95% CI 0.51-0.79). Accuracy, when compared with the reference standard, was κ=0.54 (95% CI 0.40-0.66). CONCLUSIONS: The obliquity of the fracture line, and fracture extension, created difficulty in classification in 26% of cases. 18% of our cases could not be classified by majority decision. Our results emphasise the challenges faced in classifying these fractures. Future work should focus on refining the Herscovici classification.

BACKGROUND: Richard III was the last king of England to die in battle, but how he died is unknown. On Sept 4, 2012, a skeleton was excavated in Leicester that was identified as Richard. We investigated the trauma to the skeleton with modern forensic techniques, such as conventional CT and micro-CT scanning, to characterise the injuries and establish the probable cause of death. METHODS: We assessed age and sex through direct analysis of the skeleton and from CT images. All bones were examined under direct light and multi-spectral illumination. We then scanned the skeleton with whole-body post-mortem CT. We subsequently examined bones with identified injuries with micro-CT. We deemed that trauma was perimortem when we recorded no evidence of healing and when breakage characteristics were typical of fresh bone. We used previous data to identify the weapons responsible for the recorded injuries. FINDINGS: The skeleton was that of an adult man with a gracile build and severe scoliosis of the thoracic spine. Standard anthropological age estimation techniques based on dry bone analysis gave an age range between 20s and 30s. Standard post-mortem CT methods were used to assess rib end morphology, auricular surfaces, pubic symphyseal face, and cranial sutures, to produce a multifactorial narrower age range estimation of 30-34 years. We identified nine perimortem injuries to the skull and two to the postcranial skeleton. We identified no healed injuries. The injuries were consistent with those created by weapons from the later medieval period. We could not identify the specific order of the injuries, because they were all distinct, with no overlapping wounds. Three of the injuries-two to the inferior cranium and one to the pelvis-could have been fatal. INTERPRETATION: The wounds to the skull suggest that Richard was not wearing a helmet, although the absence of defensive wounds on his arms and hands suggests he was still otherwise armoured. Therefore, the potentially fatal pelvis injury was probably received post mortem, meaning that the most likely injuries to have caused his death are the two to the inferior cranium. FUNDING: The University of Leicester.

PURPOSE: The optimal treatment of calcaneal fractures is controversial. A specific subgroup of healthy patients has good outcomes with open reduction and internal fixation using an extensile lateral approach. However, there are many patients who do not fit into this category. Consequently, they are either denied surgical intervention or put at significant risk of developing complications as a result of open surgical intervention. Minimally invasive reduction and fixation (MIRF) of calcaneal fractures can restore the height, width, length and shape of the hindfoot in addition to restoring the orientation of the posterior facet of the calcaneus (Böhler's angle). METHODS: We present a series of 31 patients treated with minimally invasive reduction and fixation technique using threaded K wires and Steinmann pins as an alternative treatment method in patients who are not suitable for open reduction and internal fixation. RESULTS: The mean time to surgery from injury was six days (range one to ten days). The mean duration of surgery was 35 minutes (range 11-52 minutes). The mean followup was 14.9 months (range of seven to 30 months). The mean change in Böhler's angle and length of the calcaneus from intra-operative fixation to final followup were 18.7° and 4.7 mm, respectively. The complication rate was low and there was one case of a superficial wound infection and no cases of deep infection or peroneal impingement in this series. CONCLUSION: The MIRF technique with the use of threaded K wires has not been previously described in the literature. In our experience, the operative time is short and can be safely performed even in the presence of extensive soft tissue swelling in the immediate period following injury. The infection risk is low and calcaneal morphology was improved and maintained in terms of Böhler's angle. This technique is suitable to be considered in patients who have significant medical co-morbidities (smokers, diabetics, peripheral vascular disease) and in those patients who are not suitable for an extensile lateral approach and internal fixation.

The topic of dog-walking injuries has recently gained notoriety through major media outlets in North America, including the Washington Post, NPR, and US News and World Report. In this review, we have compiled data from the main studies published in the past 2 decades that assess the incidence, demographics, and injury patterns related to dog leash walking. The available papers indicate that dog leash-related injuries have increased, particularly among women over 65. The most common causes of injury are dog-pulling behavior, which can result in tripping or tangling, with or without a fall, as well as upper extremity injuries. However, there is a lack of information regarding dog size, breed, training status, the type of leash used at the time of injury, and the role each factor may have in the incidence of injuries. The available data did not allow for evaluation of the impact of weather conditions on injury incidence. Information about the involved dogs, type of lead device, and weather conditions could be useful in identifying risk factors associated with dog ownership and guide prospective pet owners and their families to mitigate the risk of injuries.

HISTORY-A 47-year-old male was on a cliff when he jumped into the water below. He jumped about 50 feet. Upon landing in the water, he felt his legs separate and abduct violently. He was taken to the Emergency unit of the nearest trauma center and was found to have no injuries except to his pelvis. He could not weight bear because of pelvic pain but had normal distal sensory and motor exam and rectal exam. His-pelvis was painful to examination anteriorly with minor left-sided posterior SI pain, and he had no blood at his meatus. X-rays and CT were done, (Figures 1-5).

BACKGROUND: The purpose of this study was to compare the biomechanical properties of locked versus nonlocked lateral fibular bridge plating of comminuted, unstable ankle fractures in a mode of catastrophic failure. METHODS: We created comminuted Weber C fractures in 8 paired limbs from fresh cadavers. Fractures were plated with either standard or locked one-third tubular bridge plating techniques. Specimens were biomechanically evaluated by external rotation to failure while subjected to a compressive load approximating body weight. We measured the angle to failure, torque to failure, energy to failure and construct stiffness. RESULTS: There was no significant difference in construct stiffness or other biomechanical properties between locked and standard one-third tubular plating techniques. CONCLUSION: We found no difference in biomechanical properties between locked and standard bridge plating of a comminuted Weber C fibular fracture in a model of catastrophic failure. It is likely that augmentation of fixation with K-wires or transtibial screws provides a construct superior to locked bridge plating alone. Further biomechanical and clinical analysis is required to improve understanding of the role of locked plating in ankle fractures and in osteoporotic bone.

OBJECTIVES: To evaluate orthopedic surgeon referral of trauma patients to PT. DESIGN: Cross-sectional survey. SETTING: Alberta, Canada. PARTICIPANTS: Orthopedic surgeons and residents. METHODS: A web-based survey was utilized to poll orthopedic surgeons and residents on referral practices. Statistical analysis using Kruskal-Wallis One-Way Analysis of Variance by Ranks; Post hoc analysis using the minimum significant difference method for multiple comparisons and nonparametric correlations using Spearman's rho. RESULTS: The overall response rate was 48 %. Key indications for referral were range of motion deficits, failure to progress, strength and gait training. Of those surveyed, 72.5 and 26.1 % felt that there was either moderate or significant improvement following PT, respectively. Years in practice had a significant effect on survey responses. Residents and surgeons in practice for >20 years viewed PT as being less important in orthopedic trauma (p < 0.05) and were less likely to refer orthopedic trauma patients to PT (p < 0.05). Residents were less likely to view PT in orthopedic trauma as evidence-based (0.05) and more likely to disagree with the statement that formalized PT results in better outcomes than a prescribed home exercise program (p < 0.05). CONCLUSIONS: There are potential differences in the referral practices of orthopedists of varying levels of experience. Although outcome is viewed as positive following PT, it appears that many orthopedists view a prescribed home exercise program as an acceptable equivalent to formalized PT in the setting of orthopedic trauma. Future research should be directed at determining indicators for formalized PT.

OBJECTIVES: To determine the percentage of potentially preventable residential aged care facility (RACF) to ED transfers for potential intracranial injury post-fall. To describe rates of CT brain (CTB) performance, intracranial trauma-related findings, neurosurgical intervention, and patient outcome. METHODS: Patient lists were obtained from the hospital electronic medical record, screened for eligibility and data abstracted. Potentially preventable was defined as: (1) RACF return from ED within 24 h, regardless of CTB performance or finding; (2) ED management could reasonably have been provided at the RACF. Comparisons between those with CTB performed or not, including external signs of craniofacial trauma, anticoagulant medication use, baseline cognitive impairment and presence of an advanced care directive (ACD) were made. RESULTS: Of 784 patients, 415 (53%) were classified as potentially avoidable. Of these, 314 (76%) had a CTB. Of all 784 patients, 538 (69%) had a CTB performed. CTB was more likely with presence of external signs of craniofacial trauma (26% [95% CI 23-30] vs 20% [95% CI 15-25], P < 0.001) and anticoagulant use (59% [95% CI 55-63] vs 42% [95% CI 37-49], P < 0.001) but not for presence of cognitive impairment or ACD. From the 538 CTBs, 31 (6%) patients had acute intracranial trauma-related findings with all having conservative management. None of the 11 (1%) deaths were in the potentially preventable subgroup. CONCLUSION: Just over half of the RACF to ED transfers were classified as 'potentially avoidable'.

AIMS: This study reviews the past 30 years of research from the Canadian Orthopedic Trauma Society (COTS), to identify predictive factors that delay or accelerate the course of randomized controlled trials in orthopaedic trauma. METHODS: We conducted a methodological review of all papers published through the Canadian Orthopaedic Trauma Society or its affiliates. Data abstracted included: year of publication; journal of publication; study type; number of study sites; sample size; and achievement of sample size goals. Information about the study timelines was also collected, including: the date of study proposal to COTS; date recruitment began; date recruitment ended; and date of publication. RESULTS: In total, 22 studies have been published through the COTS working group, 13 of which are randomized controlled trials (RCTs). In total, 1,423 individual patients have been involved in COTS studies, a mean of 110 patients per trial (22 to 424). Each study was conducted across a mean of approximately six centres (1 to 11) and took nearly ten years (mean 119.9 months (59 to 188)) from presentation of concept to publication. The mean length of enrolment was 63 months (26 to 113) and the mean time from cessation of enrolment to publication 51 months (19 to 78). Regardless of sample size, the only factor associated with a decreased length of enrolment was a higher number of clinical sites (p = 0.041). Neither study sample size nor length of enrolment were associated with total time to publication. CONCLUSION: Over the last three decades, COTS has developed a multinational strategy to produce high-quality evidence in the field of orthopaedic trauma through 13 multicentre RCTs. Future efficiencies can be realized by recruitment of more clinical sites, improving connectivity between the sites, and the promotion of national streamlined ethics processes.

BACKGROUND: Intra-articular calcaneal fractures are complex injuries, and CT imaging has become the standard imaging in the preoperative assessment. Most classifications of these fractures are CT-based but have been associated with limited interobserver agreement. Three-dimensional imaging has become widely available and may give a better perspective but often with 1 image only. There is not much evidence of the added value of this imaging, compared with the CT imaging. METHODS: Eight experienced trauma surgeons assessed 28 different intra-articular calcaneal fractures, on conventional radiology (CR), CT, and 3-D imaging. All had extensive experience in the diagnosis and treatment of this difficult injury. The main questions concerned Sanders classification, the severity of the injury and the difficulty of the operative procedure, choice of approach, and choice of procedure. RESULTS: The classical 2-D CT imaging of the fractures were associated with a higher Sanders classification ranking, compared with the 3-D imaging scores. However, the interobserver agreement, as measured by the Fleiss kappa, was low for all 3 imaging modalities. We found more frequent Sanders III and IV classifications with CT scan imaging compared with 3-D imaging or CR. The scores obtained after assessing 3-D imaging were also not statistically significantly different from the scores of a consensus achieved by 2 authors and based on the 3 imaging modalities and the perioperative diagnosis. CONCLUSION: The 3-D imaging may result in a more realistic view, reducing the frequency of classifying Sanders III fractures than with the 2-D CT imaging series. 3-D imaging may be more reliable than CT in the planning of operative treatment of displaced intra-articular calcaneal fractures. LEVEL OF EVIDENCE: Level III.
RESUMEN
Bone infection represents a serious complication of orthopedic surgery and Staphylococcus aureus is the most common pathogen. To improve the understanding of host-pathogen interaction, we developed a biospecimen registry (AO Trauma CPP Bone Infection Registry) to collect clinical data, bacterial isolates, and serum from patients with S. aureus bone infection. A prospective multinational registry with a 12-month follow-up was created to include adult patients (18 years or older) with culture-confirmed S. aureus infection in long bones after fracture fixation or arthroplasty. Baseline patient attributes and details on infections and treatments were recorded. Blood and serum samples were obtained at baseline, 6, and 12 months. Patient-reported outcomes were collected at 1, 6, and 12 months. Clinical outcomes were recorded. Two hundred and ninety-two patients with fracture-related infection (n = 157, 53.8%), prosthetic joint infection (n = 86, 29.5%), and osteomyelitis (n = 49, 16.8%) were enrolled. Methicillin-resistant S. aureus was detected in 82 patients (28.4%), with the highest proportion found among patients from North American sites (n = 39, 48.8%) and the lowest from Central European sites (n = 18, 12.2%). Patient outcomes improved at 6 and 12 months in comparison to baseline. The SF-36 physical component summary mean (95% confidence interval) score, however, did not reach 50 at 12 months. The cure rate at the end of the study period was 62.1%. Although patients improved with treatment, less than two-thirds were cured in 1 year. At 12-month follow-up, patient-reported outcome scores were worse for patients with methicillin-resistant S. aureus infections.
