Background: Observational studies have suggested that accelerated surgery is associated with improved outcomes in patients with a hip fracture. The HIP ATTACK trial assessed whether accelerated surgery could reduce mortality and major complications. Methods:We randomised 2970 patients from 69 hospitals in 17 countries. Patients with a hip fracture that required surgery and were ≥45 years of age were eligible. Patients were randomly assigned to accelerated surgery (goal of surgery within 6 hours of diagnosis; 1487 patients) or standard care (1483 patients). The co-primary outcomes were 1.) mortality, and 2.) a composite of major complications (i.e., mortality and non-fatal myocardial infarction, stroke, venous thromboembolism, sepsis, pneumonia, life-threatening bleeding, and major bleeding) at 90 days after randomisation. Outcome adjudicators were masked to treatment allocation, and patients were analysed according to the intention-to-treat principle; ClinicalTrials.gov, NCT02027896. Findings:The median time from hip fracture diagnosis to surgery was 6 hours (interquartile range [IQR] 4-9) in the accelerated-surgery group and 24 hours (IQR 10-42) in the standard-care group, p<0.0001. Death occurred in 140 patients (9%) assigned to accelerated surgery and 154 patients (10%) assigned to standard care; hazard ratio (HR) 0.91, 95% CI 0.72-1.14; absolute risk reduction (ARR) 1%, 95% CI -1-3%; p=0.40. The primary composite outcome occurred in 321 patients (22%) randomised to accelerated surgery and 331 patients (22%) randomised to standard care; HR 0.97, 95% CI 0.83-1.13; ARR 1%, 95% CI -2-3%; p=0.71.Interpretation: Among patients with a hip fracture, accelerated surgery did not significantly lower the risk of mortality or a composite of major complications compared to standard care.
as magnetic resonance imaging (MRI) or 3D ultrasound are costly, require specialist expertise, and take a long time to perform and process. These limitations may explain, in part, why the measurement of muscle volume has not yet transi-tioned into clinical practice or been included in large-scale clinical trials. To date, research studies of muscle volume in CP have low numbers of participants or are restricted to one or two muscles. Therefore, for larger research studies to be performed, and for muscle volume to become a routine clinical assessment, a new clinically feasible approach for measuring muscle volume is required. The work of Schless et al. 5 suggests that muscle volume may be estimated from measurements made using a standard two-dimensional (2D) ultrasound scanner. Schless et al. reported a strong linear relationship between muscle volume and the product of muscle length and cross-sectional area in the medial gastrocnemius. 5 This strong relationship has implications for the clinical feasibility of assessing muscle volume in this group. However, the work described is not a complete test of the utility and accuracy of estimating muscle volume by 2D ultrasound. The measurements of muscle length and anatomical cross-sectional area were made using a 3D ultrasound system. It cannot be assumed that by using a 2D method in isolation the relationship would be as strong as Schless et al. report. The authors identified the muscle insertion and musculo-tendinous junction from within a reconstructed 3D data set postdata collection. This has the advantage of allowing longitudinal reconstructions of the whole muscle length to be viewed, which greatly aids in identifying muscle end points. In practice, a 2D assessment would involve measurement of muscle length by tape measure guided by live 2D ultrasound imaging, and the identification of an optimal ultrasound image from which to estimate the anatomical cross-sectional area. Variation in probe location, orientation, and surface pressure are all likely to increase variability in the data set. Therefore, this 2D technique for estimating muscle volume is likely to have lower repeatability compared to MRI and 3D ultrasound techniques. However, accepting a suboptimal 2D technique that is simple, realistic, and feasible may be the way forward to enable large scale research studies to be performed and ultimately for a routine clinical assessment technique to be developed. The authors use an unconventional definition of the prox-imal origin of the medial gastrocnemius at the tibia, rather than utilising the real anatomical origin at the formal con-dyle. Although this limitation is unlikely to have a significant impact on the strength of the relationship between muscle volume and the product of muscle length and cross-sectional area, the regression equation developed by the authors is only valid for measurements made following the same definition. Furthermore, the findings of Schless et al. may not be generalisable to other muscles. Further investigation of the reliability ...
Background The Lancet Commission on Global Surgery established the Three Delays framework, categorising delays in accessing timely surgical care into delays in seeking care (First Delay), reaching care (Second Delay), and receiving care (Third Delay). Globally, knowledge gaps regarding delays for fracture care, and the lack of large prospective studies informed the rationale for our international observational study. We investigated delays in hospital admission as a surrogate for accessing timely fracture care and explored factors associated with delayed hospital admission. MethodsIn this prospective observational substudy of the ongoing International Orthopaedic Multicenter Study in Fracture Care (INORMUS), we enrolled patients with fracture across 49 hospitals in 18 low-income and middle-income countries, categorised into the regions of China, Africa, India, south and east Asia, and Latin America. Eligible patients were aged 18 years or older and had been admitted to a hospital within 3 months of sustaining an orthopaedic trauma. We collected demographic injury data and time to hospital admission. Our primary outcome was the number of patients with open and closed fractures who were delayed in their admission to a treating hospital. Delays for patients with open fractures were defined as being more than 2 h from the time of injury (in accordance with the Lancet Commission on Global Surgery) and for those with closed fractures as being a delay of more than 24 h. Secondary outcomes were reasons for delay for all patients with either open or closed fractures who were delayed for more than 24 h. We did logistic regression analyses to identify risk factors of delays of more than 2 h in patients with open fractures and delays of more than 24 h in patients with closed fractures. Logistic regressions were adjusted for region, age, employment, urban living, health insurance, interfacility referral, method of transportation, number of fractures, mechanism of injury, and fracture location. We further calculated adjusted relative risk (RR) from adjusted odds ratios, adjusted for the same variables. This study was registered with ClinicalTrials.gov, NCT02150980, and is ongoing. Findings Between April 3, 2014, and May 10, 2019, we enrolled 31 255 patients with fractures, with a median age of 45 years (IQR 31-62), of whom 19 937 (63•8%) were men, and 14 524 (46•5%) had lower limb fractures, making them the most common fractures. Of 5256 patients with open fractures, 3778 (71•9%) were not admitted to hospital within 2 h. Of 25 999 patients with closed fractures, 7141 (27•5%) were delayed by more than 24 h. Of all regions, Latin America had the greatest proportions of patients with delays (173 [88•7%] of 195 patients with open fractures; 426 [44•7%] of 952 with closed fractures). Among patients delayed by more than 24 h, the most common reason for delays were interfacility referrals (3755 [47•7%] of 7875) and Third Delays (cumulatively interfacility referral and delay in emergency department: 3974 [50•5%]), while Second Delays ...
Surgical procedures for the correction of equinus deformity by lengthening of the gastrocnemius-soleus complex vary in terms of selectivity, stability, and range of correction. Procedures for the correction of equinus deformity have different anatomical and biomechanical characteristics. Clinical trials are needed to determine whether these differences are of clinical importance. It may be appropriate for surgeons to select a procedure involving the zone best suited to the clinical needs of a specific patient.
Children with glucocorticoid-treated illnesses are at risk for osteoporotic vertebral fractures, and growing awareness of this has led to increased monitoring for these fractures. However scant literature describes developmental changes in vertebral morphology that can mimic fractures. The goal of this paper is to aid in distinguishing between normal variants and fractures. We illustrate differences using lateral spine radiographs obtained annually from children recruited to the Canada-wide STeroid-Associated Osteoporosis in the Pediatric Population (STOPP) observational study, in which 400 children with glucocorticoid-treated leukemia, rheumatic disorders, and nephrotic syndrome were enrolled near glucocorticoid initiation and followed prospectively for 6 years. Normal variants mimicking fractures exist in all regions of the spine and fall into two groups. The first group comprises variants mimicking pathological vertebral height loss, including not-yet-ossified vertebral apophyses superiorly and inferiorly, which can lead to a vertebral shape easily over-interpreted as anterior wedge fracture, physiological beaking, or spondylolisthesis associated with shortened posterior vertebral height. The second group includes variants mimicking other radiologic signs of fractures: anterior vertebral artery groove resembling an anterior buckle fracture, Cupid's bow balloon disk morphology, Schmorl nodes mimicking concave endplate fractures, and parallax artifact resembling endplate interruption or biconcavity. If an unexpected vertebral body contour is detected, careful attention to its location, detailed morphology, and (if available) serial changes over time may clarify whether it is a fracture requiring change in management or simply a normal variant. Awareness of the variants described in this paper can improve accuracy in the diagnosis of pediatric vertebral fractures.
