RESUMEN
OBJECTIVE: The primary objective was to determine the population prevalence of glenohumeral joint imaging abnormalities in asymptomatic adults. METHOD: We systematically reviewed studies reporting the prevalence of X-ray, ultrasound (US), computed tomography, and magnetic resonance imaging (MRI) abnormalities in adults without shoulder symptoms (PROSPERO registration number CRD42018090041). This report presents the glenohumeral joint imaging findings. We searched Ovid MEDLINE, Embase, CINAHL and Web of Science from inception to June 2023 and assessed risk of bias using a tool designed for prevalence studies. The primary analysis was planned for the general population. The certainty of evidence was assessed using a modified Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) for prognostic studies. RESULTS: Thirty-five studies (4 X-ray, 10 US, 20 MRI, 1 X-ray and MRI) reported useable prevalence data. Two studies were population-based (846 shoulders), 15 studies included miscellaneous study populations (1715 shoulders) and 18 included athletes (727 shoulders). All were judged to be at high risk of bias. Clinical diversity precluded pooling. Population prevalence of glenohumeral osteoarthritis ranged from 15% to 75% (2 studies, 846 shoulders, 1 X-ray, 1 X-ray and MRI; low certainty evidence). Prevalence of labral abnormalities, humeral head cysts and long head of biceps tendon abnormalities were 20%, 5%, 30% respectively (1 study, 20 shoulders, X-ray and MRI; very low certainty evidence). CONCLUSION: The population-based prevalence of glenohumeral joint imaging abnormalities in asymptomatic individuals remains uncertain, but may range between 30% and 75%. Better estimates are needed to inform best evidence-based management of people with shoulder pain.
RESUMEN
BACKGROUND: Humeral shaft fractures are relatively common injuries and are classified according to location and fracture morphology. Epidemiological studies improve understanding of injury patterns and lay foundations for future research. There are only a few published larger epidemiological studies on humeral shaft fractures. METHODS: We retrospectively analyzed the medical records of adult patients having sustained a humeral shaft fracture treated in the Helsinki University Hospital between 2006 and 2016. We recorded patient and fracture characteristics, timing and mechanism of injury, associated injuries, and 1-year mortality. RESULTS: We identified 914 patients (489 females, median age = 61.4 years; 425 males, median age = 50.4 years) with 936 fractures. Over 60% of these fractures were sustained from simple falls. The patient age distribution was bimodal, with highest fracture rates in elderly females and young males. We divided the fractures into typical traumatic, periprosthetic, and pathological fractures. Of the 872 typical traumatic fractures, 3.0% were open. In addition, there were 24 (2.6%) periprosthetic and 40 (4.3%) pathological fractures. An associated injury was found in 24% of patients, with primary radial nerve palsy (PRNP) being the most common (10%). PRNPs were more common in distal shaft fractures and high energy injuries. The 1-year mortality was 9.2%. CONCLUSIONS: In this study, the most common injury mechanism was a simple fall. The most common associated injury was PRNP. The observed bimodal fracture distribution is consistent with previous literature.

BACKGROUND: Two common ways of assessing the clinical relevance of treatment outcomes are the minimal important difference (MID) and the patient acceptable symptom state (PASS). The former represents the smallest change in the given outcome that makes people feel better, while the latter is the symptom level at which patients feel well. METHODS: We recruited 124 patients with a humeral shaft fracture to a randomised controlled trial comparing surgery to nonsurgical care. Outcome instruments included the Disabilities of Arm, Shoulder, and Hand (DASH) score, the Constant-Murley score, and two numerical rating scales (NRS) for pain (at rest and on activities). A reduction in DASH and pain scores, and increase in the Constant-Murley score represents improvement. We used four methods (receiver operating characteristic [ROC] curve, the mean difference of change, the mean change, and predictive modelling methods) to determine the MID, and two methods (the ROC and 75th percentile) for the PASS. As an anchor for the analyses, we assessed patients' satisfaction regarding the injured arm using a 7-item Likert-scale. RESULTS: The change in the anchor question was strongly correlated with the change in DASH, moderately correlated with the change of the Constant-Murley score and pain on activities, and poorly correlated with the change in pain at rest (Spearman's rho 0.51, -0.40, 0.36, and 0.15, respectively). Depending on the method, the MID estimates for DASH ranged from -6.7 to -11.2, pain on activities from -0.5 to -1.3, and the Constant-Murley score from 6.3 to 13.5. The ROC method provided reliable estimates for DASH (-6.7 points, Area Under Curve [AUC] 0.77), the Constant-Murley Score (7.6 points, AUC 0.71), and pain on activities (-0.5 points, AUC 0.68). The PASS estimates were 14 and 10 for DASH, 2.5 and 2 for pain on activities, and 68 and 74 for the Constant-Murley score with the ROC and 75th percentile methods, respectively. CONCLUSION: Our study provides credible estimates for the MID and PASS values of DASH, pain on activities and the Constant-Murley score, but not for pain at rest. The suggested cut-offs can be used in future studies and for assessing treatment success in patients with humeral shaft fracture.

INTRODUCTION: Shoulder pain is a substantial medical and socioeconomic problem in most societies, affecting the ability to work or carry out leisure time activities as well as subsequently influencing physical and psychological well-being. According to a nationwide survey in Finland, 27% of the population reported shoulder pain within the last 30 days. In clinical practice, imaging findings of structural abnormalities are typically thought to explain symptoms, even though such findings are also prevalent in asymptomatic individuals, particularly with increasing age. Overall, there is a paucity of high-quality evidence on the prevalence, clinical relevance and prognosis of 'abnormal' imaging findings of the shoulder.The aim of the Finnish Imaging of Shoulder (FIMAGE) study is fourfold: to assess (1) the prevalence of shoulder symptoms and the most common anatomical variants and imaging abnormalities of the shoulder; (2) the concordance between shoulder symptoms, function and imaging abnormalities; (3) the most important determinants of symptoms, function and imaging abnormalities; and (4) the course of shoulder complaints over 5 years. METHODS: The FIMAGE target population of 600 participants, aged 40-75 years, will be randomly selected from a nationally representative general population sample of 9922 individuals originally recruited for the Finnish Health 2000 Survey. On giving informed consent, the participants will be invited to a clinical visit that includes assessment of general health, shoulder symptoms, bilateral shoulder examination and imaging of both shoulders with plain radiography and MRI. ETHICS AND DISSEMINATION: The study has been approved by the Institutional Review Board of the Helsinki and Uusimaa Hospital District. The findings will be published according to the Strengthening the Reporting of Observational Studies in Epidemiology criteria. TRIAL REGISTRATION NUMBER: NCT05641415.

INTRODUCTION: The ischaemic pain of acute compartment syndrome (ACS) can be difficult to discriminate from the pain linked to an associated fracture. Lacking objective measures, the decision to perform fasciotomy is based on clinical findings and performed at a low level of suspicion. Biomarkers of muscle cell damage may help to identify and monitor patients at risk, similar to current routines for patients with acute myocardial infarction. This study will test the hypothesis that biomarkers of muscle cell damage can predict ACS in patients with tibial fractures. METHODS AND ANALYSIS: Patients aged 15-65 years who have suffered a tibial fracture will be included. Plasma (P)-myoglobin and P-creatine phosphokinase will be analysed at 6-hourly intervals after admission to the hospital (for 48 hours) and-if applicable-after surgical fixation or fasciotomy (for 24 hours). In addition, if ACS is suspected at any other point in time, blood samples will be collected at 6-hourly intervals. An independent expert panel will assess the study data and will classify those patients who had undergone fasciotomy into those with ACS and those without ACS. All primary comparisons will be performed between fracture patients with and without ACS. The area under the receiver operator characteristics curves will be used to identify the success of the biomarkers in discriminating between fracture patients who develop ACS and those who do not. Logistic regression analyses will be used to assess the discriminative abilities of the biomarkers to predict ACS corrected for prespecified covariates. ETHICS AND DISSEMINATION: The study has been approved by the Regional Ethical Review Boards in Linköping (2017/514-31) and Helsinki/Uusimaa (HUS/2500/2000). The BioFACTS study will be reported in accordance with the Strengthening the Reporting of Observational Studies in Epidemiology recommendations. TRIAL REGISTRATION NUMBER: NCT04674592.

BACKGROUND AND AIMS: Osteoarthritis (OA) is the world's most common joint disease and there is currently no cure. Glenohumeral osteoarthritis (GHOA) accounts for an estimated 5%-17% of patients with shoulder complaints. The etiology of GHOA is multifactorial, and we review the various non-specific and specific risk factors and further sub-classify them into local and systemic factors. MATERIALS AND METHODS: Data for this review article were identified by searches of MEDLINE, PubMed, and references from relevant articles using search terms such as "glenohumeral," "osteoarthritis," "epidemiology," "etiology," "imaging," and "pathophysiology." Only articles published in English, German, and Finnish between 1957 and 2017 were included. RESULTS: The prevalence of radiological shoulder OA has been estimated to be as high as 16%-20% in the middle-aged and elderly population, but the concordance between structural findings and symptoms seems to be weak, as many of these individuals are asymptomatic. The vast majority of GHOA is related to non-specific factors, namely advancing age, while specific risk factors are commonly found in young patients. Diagnosis of GHOA is made when typical clinical features and defined radiological findings overlap in an individual. CONCLUSION: Conclusion: Ultimately the determinants of shoulder pain in GHOA remain incompletely understood. Improved understanding of the etiology and diagnosis of GHOA will enable clinicians to better determine which patients will benefit from different treatment modalities, as well as provide new avenues to potential treatments.
