An approach leveraging radiomics and model checking for the automatic early diagnosis of adhesive capsulitis.

Adhesive Capsulitis of the shoulder is a painful pathology limiting shoulder movements, commonly known as "Frozen Shoulder". Since this pathology limits movement, it is important to make an early diagnosis. Diagnosing capsulitis relies on clinical assessment, although diagnostic imaging, such as Magnetic Resonance Imaging, can provide predictive or supportive information for specific characteristic signs. However, its diagnosis is not so simple nor so immediate, indeed it remains a difficult topic for many general radiologists and expert musculoskeletal radiologists. This study aims to investigate whether it is possible to use disease signs within a medical image to automatically diagnose Adhesive Capsulitis. To this purpose, we propose an automatic Model Checking-based approach to quickly diagnose the Adhesive Capsulitis taking as input the radiomic feature values from the medical images. Furthermore, we compare the performance achieved by our method with diagnostic results obtained by professional radiologists with different levels of experience. To the best of our knowledge, this is the first method for the automatic diagnosis of Adhesive Capsulitis of the Shoulder.

Isolated tuberculosis of the patella mimicking as prepatellar bursitis.

Patellar tuberculosis (TB) is a rare manifestation of musculoskeletal tuberculosis, accounting for a small proportion of cases. This case report presents a detailed analysis of a female patient in her early 30s who presented with isolated TB of the patella without concurrent pulmonary involvement. The patient received antitubercular chemotherapy, consisting of a 4-month intensive phase followed by an 8-month continuation phase. This case report underscores the rarity and diagnostic complexities associated with patellar TB. The condition often presents with non-specific symptoms, often mimicking prepatellar bursitis, necessitating a high level of clinical suspicion, particularly in patients from the endemic areas. Radiographic imaging and histopathological examination play crucial roles in establishing an accurate diagnosis. Antitubercular chemotherapy forms the cornerstone of treatment while surgical intervention is reserved for cases of extensive bone destruction or treatment failure.

Risk factors and predictive models for frozen shoulder.

This study aims to explore the risk factors associated with frozen shoulder (FS) and develop a predictive model for diagnosing FS, in order to facilitate early detection of the condition. A total of 103 patients diagnosed with FS and admitted to the Department of Joint Surgery at Suining Central Hospital between October 2021 and October 2023 were consecutively included in the study. Additionally, 309 individuals without shoulder joint diseases, matched for age and gender, who visited the department during the same time, were included as the control group.The complete recording of clinical data for all patients was followed by the utilization of statistical tests such as the Mann-Whitney U test, sample t test, and chi-square test to compare different groups. Additionally, multivariate binary logistic regression analysis was employed to identify risk factors associated with the occurrence of FS in patients, leading to the establishment of a prediction model and derivation of a simplified equation. The diagnostic effectiveness of individual indicators and prediction models was assessed through the use of receiver operating characteristic (ROC) curve analysis. In the sample of 103 individuals, 35 were identified as male and 68 as female, with an average age range of 40-70 years (mean age: 54.20 ± 6.82 years). The analysis conducted between different groups revealed that individuals with a low body mass index (BMI), in conjunction with other factors such as diabetes, cervical spondylosis, atherosclerosis, and hyperlipidemia, were more susceptible to developing FS. Logistic regression analysis further indicated that low BMI, diabetes, cervical spondylosis, and hyperlipidemia were significant risk factors for the occurrence of FS. These variables were subsequently incorporated into a predictive model, resulting in the creation of a simplified equation.The ROC curve demonstrated that the combined indicators in the predictive model exhibited superior diagnostic efficacy compared to single indicators, as evidenced by an area under the curve of 0.787, sensitivity of 62.1%, and specificity of 82.2%. Low BMI, diabetes, cervical spondylosis, and hyperlipidemia are significant risk factors associated with the occurrence of FS. Moreover, the utilization of a prediction model has demonstrated superior capability in forecasting the likelihood of FS compared to relying solely on individual indicators. This finding holds potential in offering valuable insights for the early diagnosis of FS.

Combined MediaPipe and YOLOv5 range of motion assessment system for spinal diseases and frozen shoulder.

Spinal diseases and frozen shoulder are prevalent health problems in Asian populations. Early assessment and treatment are very important to prevent the disease from getting worse and reduce pain. In the field of computer vision, it is a challenging problem to assess the range of motion. In order to realize efficient, real-time and accurate assessment of the range of motion, an assessment system combining MediaPipe and YOLOv5 technologies was proposed in this study. On this basis, Convolutional Block Attention Module (CBAM) is introduced into the YOLOv5 target detection model, which can enhance the extraction of feature information, suppress background interference, and improve the generalization ability of the model. In order to meet the requirements of large-scale computing, a client/server (C/S) framework structure is adopted. The evaluation results can be obtained quickly after the client uploads the image data, providing a convenient and practical solution. In addition, a game of "Picking Bayberries" was developed as an auxiliary treatment method to provide patients with interesting rehabilitation training.

[A man with a swollen knee]. / Een man met een gezwollen knie.

This case concerns a 58-year-old man who had a progressively swollen knee over the course of 4 months. X-ray showed bursal swelling without skeletal abnormalities. Diagnostic puncture showed red/serous fluid and pathology of the extirpated bursa showed signs of chronic pre-patellar bursitis, most likely caused by a previous trauma.

Psychometric properties of the Disability of Arm Shoulder and Hand (DASH) in subjects with frozen shoulder: a reliability and validity study.

BACKGROUND: Frozen Shoulder (FS) is a painful condition characterized by severe pain and progressive restriction of shoulder movement, leading to functional impairment and reduced quality of life. While different Patient Reported Outcome Measurements (PROMs) tools exist for assessing shoulder diseases, few specific PROMs are validated for FS patients. PURPOSE: This study aims to assess the psychometric properties of the Disability of Arm, Shoulder, and Hand (DASH) questionnaire in FS patients. METHODS: One hundred and twenty-four subjects (mean ± SD age = 55.4 ± 7.9 years; 55.6% female) diagnosed with FS were included and completed the DASH questionnaire, the Numerical Pain Rating Scale (NPRS), the Shoulder Pain and Disability Index (SPADI), and the Short-Form Health Survey 36 (SF-36). Floor or ceiling effects were investigated. Structural validity was analysed through a unidimensional Confirmatory Factor Analysis (CFA), internal consistency through Cronbach's alpha, test-retest reliability through the Intraclass Correlation coefficient (ICC), measurement error through the Standard Error of Measurement (SEM), and the Minimum Detectable Change (MDC), and construct validity through the hypothesis testing with the correlation with the other outcome measures used. RESULTS: No floor or ceiling effects were observed. CFA confirmed a one-factor structure after addressing local item dependency (Root Mean Square Error of Approximation = 0.055; Standardized Root Mean Square Residual = 0.077; Comparative Fit Index = 0.970; Tucker-Lewis Index = 0.968). Cronbach's alpha was high (= 0.951), and test-retest reliability was excellent (ICC = 0.999; 95% CI: 0.998-1.000). SEM was equal to 0.5 points, and MDC to 1.5 points. Construct validity was considered satisfactory as 80% of the a-priori hypotheses were met. CONCLUSION: The DASH questionnaire demonstrated good psychometric properties in FS patients, supporting its use as a valuable tool for assessing the impact of FS in clinical and research settings.

[OLECRANON BURSITIS].

INTRODUCTION: The olecranon bursa is a pocket-like structure located at the posterior aspect of the elbow that is responsible for the smooth movement of the surrounding tissues. Frequently, it is the source of elbow pain due to an inflammation which may be caused by local injury or penetration of bacteria through the skin. This can lead to an initial acute and possibly a late chronic inflammation. Chronic inflammation may originate from systemic diseases such as gout and rheumatoid arthritis as well. The treatment of olecranon bursitis may be conservative (non-surgical) or surgical. Recently, there is more supporting evidence for the use of conservative management over surgical intervention in treating olecranon bursitis.

[Frozen Shoulder - a short review for the practice].

INTRODUCTION: The Frozen Shoulder is a frequently encountered pathology in clinical practice. This condition often coexists with various comorbidities and is characterized by severe pain and a significantly restricted motion of the affected shoulder. A limited passive external rotation with the arm in adduction, with no signs of any other pathology that could explain the finding, such as shoulder osteoarthritis or an undetected posterior dislocation, is pathognomonic. The course of the disease typically spans over one to two years and is usually self-limiting. In the vast majority of cases, this condition can be managed conservatively. Keywords: shoulder, shoulder stiffness, shoulder pain, conservative therapy.

Does the psychological profile of a patient with frozen shoulder predict future outcome? A systematic review.

BACKGROUND AND PURPOSE: Frozen shoulder (FS) is defined as a condition characterised by functional restriction and daily and nightly pain. As in other shoulder pathologies, the manifestation of psychological factors is recognised in FS; however, from a psychological point of view, only few studies have reported its prognostic value. The aim of this systematic review is to investigate, in patients with FS, the prognostic value of psychological factors on pain, function, disability, health-related quality of life, return to work and time to recovery. MATERIALS AND METHODS: This systematic review was reported following the Preferred Reporting Items for Systematic reviews and Meta-Analysis-PRISMA 2020 guideline. The authors followed the Cochrane Handbook for Systematic review of Intervention as methodological guidance. The Quality in Prognostic Studies-QUIPS tool was used to assess the risk of bias. RESULTS: Pain-related fear and depression could be prognostic regarding patient-reported outcome measures assessing shoulder function, disability, and pain; instead, pain catastrophizing could have a prognostic value assessed by the disability of the arm shoulder and hand -DASH scale. Anxiety would appear to impact on disability and pain. DISCUSSION AND CONCLUSIONS: As widely reported in numerous musculoskeletal conditions, also in FS psychological factors influence the physical dimension such as pain, disability and function. Therefore, clinicians should be encouraged to identify these factors through a comprehensive assessment of the bio-psychological profile of each individual with FS. Perhaps, patients with FS that show such psychological prognostic factors could benefit from a comprehensive and shared approach with other dedicated professionals.

2023 French recommendations for diagnosing and managing prepatellar and olecranon septic bursitis.

Septic bursitis (SB) is a common condition accounting for one third of all cases of inflammatory bursitis. It is often related to professional activities. Management is heterogeneous and either ambulatory or hospital-based, with no recommendations available. This article presents recommendations for managing patients with septic bursitis gathered by 18 rheumatologists from the French Society for Rheumatology work group on bone and joint infections, 1 infectious diseases specialist, 2 orthopedic surgeons, 1 general practitioner and 1 emergency physician. This group used a literature review and expert opinions to establish 3 general principles and 11 recommendations for managing olecranon and prepatellar SB. The French Health authority (Haute Autorité de santé [HAS]) methodology was used for these recommendations. Designed for rheumatologists, general practitioners, emergency physicians and orthopedic surgeons, they focus on the use of biological tests and imaging in both outpatient and inpatient management. Antibiotic treatment options (drugs and duration) are proposed for both treatment modalities. Finally, surgical indications, non-drug treatments and prevention are covered by specific recommendations.

Management of Greater Trochanteric Pain Syndrome After Total Hip Arthroplasty: Practice Patterns and Surgeon Attitudes.

INTRODUCTION: Greater trochanteric pain syndrome (GTPS) or trochanteric bursitis is described as pain on the lateral side of the hip that does not involve the hip joint and can be elicited clinically by palpation over the greater trochanter. To date, there remains no consensus on clinical guidelines for either diagnosis or management of GTPS. METHODS: To understand the practice patterns, beliefs, and attitudes relating to the management of GTPS after total hip arthroplasty, a survey was developed and completed by Canadian arthroplasty surgeons. The final survey consisted of 23 questions divided into three sections: 1) screening questions; 2) demographic information; and 3) practice patterns, attitudes, and beliefs. RESULTS: Most surgeons use physical examination alone for diagnosis. A detailed analysis indicates that surgeons primarily treat GTPS with oral anti-inflammatories (57.1%), structured physiotherapy (52.4%), and steroid injections (45.2%). Management options are typically nonsurgical and comprise a combination of either unstructured or targeted physiotherapy, corticosteroid injections, or platelet-rich plasma. DISCUSSION: There remains an absence of clinical consensus for the diagnosis and management of GTPS after total hip arthroplasty. Physical examination is most often relied on, regardless of the availability of imaging aids. While common treatments of GTPS were identified, up to one-third of patients fail initial therapy.

The Risk of Shoulder Adhesive Capsulitis in Individuals with Prediabetes and Type 2 Diabetes Mellitus: A Longitudinal Nationwide Population-Based Study.

BACKGRUOUND: This study aimed to investigate the association between type 2 diabetes mellitus (T2DM) and shoulder adhesive capsulitis (AC) using a large-scale, nationwide, population-based cohort in the Republic of Korea. METHODS: A total of 3,471,745 subjects aged over 20 years who underwent a National Health Insurance Service medical checkup between 2009 and 2010 were included in this study, and followed from the date of their medical checkup to the end of 2018. Subjects were classified into the following four groups based on the presence of dysglycemia and history of diabetes medication: normal, prediabetes, newly diagnosed T2DM (new-T2DM), and T2DM (claim history for antidiabetic medication). The endpoint was new-onset AC during follow-up. The incidence rates (IRs) in 1,000 person-years and hazard ratios (HRs) of AC for each group were analyzed using Cox proportional hazard regression models. RESULTS: The IRs of AC were 9.453 (normal), 11.912 (prediabetes), 14.933 (new-T2DM), and 24.3761 (T2DM). The adjusted HRs of AC in the prediabetes, new-T2DM, and T2DM groups were 1.084 (95% confidence interval [CI], 1.075 to 1.094), 1.312 (95% CI, 1.287 to 1.337), and 1.473 (95% CI, 1.452 to 1.494) compared to the normal group, respectively. This secular trend of the HRs of AC according to T2DM status was statistically significant (P<0.0001). CONCLUSION: This large-scale, longitudinal, nationwide, population-based cohort study of 3,471,745 subjects confirmed that the risk of AC increases in prediabetic subjects and is associated with T2DM status.

Non-surgical treatment of aseptic olecranon bursitis: A systematic review.

OBJECTIVE: Olecranon bursitis (OB), characterized by inflammation and fluid collection in the olecranon bursa is a commonly encountered out-patient condition. The data is heterogeneous regarding a stepwise and standardized approach to aseptic OB treatment and the efficacy of intra-bursal corticosteroid injections (CSI). The objective of this review is to systematically evaluate the non-surgical treatment options for aseptic OB. METHODS: This systematic review was conducted in accordance with PRISMA recommendations. The English and non-English literature search was performed in 5 medical databases to identify studies evaluating the treatment of OB. All included studies were evaluated for risk of bias (RoB) using the revised Cochrane RoB tool for randomized control trials (RCTs) and the Newcastle-Ottawa Scale (NOS) for case-control and cohort studies. RESULTS: For the final analyses, 2 RCTs and 2 observational studies were included. The RoB for the RCTs was high and both failed to demonstrate a significant difference in terms of the resolution of OB and bursal tenderness among various invasive and non-invasive treatment options. Corticosteroid injection (CSI) was associated with a significant decline in the duration of symptoms. However, it was associated with a higher number of complications including bursal infection and skin atrophy. CONCLUSION: Based on the available data, it appears that the clinical resolution of aseptic OB can occur with conservative methods if implemented earlier in the disease course. Although CSI is more effective than other treatments, it should be reserved for refractory cases because of a higher complication rate.

Upper-crossed syndrome and disability in shoulder adhesive capsulitis.

STUDY DESIGN: Cross-sectional analytical study. INTRODUCTION: Adhesive capsulitis (AC) is a long-standing condition with varying extents of disability seen among patients. The role of postural manifestations and contractile tissue involvement in this condition is poorly understood and yet to be explored. PURPOSE: This study aimed to analyze if individuals with adhesive capsulitis demonstrated the characteristics of an upper crossed syndrome (UCS) postural manifestation and whether or not its presence affected the extent of disability experienced by this population. METHODS: Sixty-five individuals with AC were assessed for the presence of UCS. Scapular muscle strength and length alterations, forward head posture (FHP), and disability were assessed and compared between those with and without UCS. Paired T test and an independent T test were utilized to compare means within and between these groups, respectively, while non-parametric measures were utilized for their skewed counterparts. Phi coefficient (φ) was used to determine the strength of association between the descriptive patient characteristics. The correlation between symptom duration and degree of postural involvement was analyzed using Pearson's correlation coefficient. RESULTS: 43.1% of the study population demonstrated UCS and 80% FHP with a significant negative correlation between Cranio Vertebral Angle and chronicity of AC (r = -0.27). Individuals with AC demonstrated significantly decreased scapular muscle strength (p = <.001) and pectoralis minor length on the affected side (p = .03). No differences were seen between groups with and without UCS. The mean SPADI scores between groups demonstrated a more significant level of perceived pain and disability in individuals with UCS (p = .049). CONCLUSIONS: As seen in UCS, individuals with AC demonstrated alterations in movement patterns and posture. UCS was seen to contribute towards the existing disability in AC. This study suggests a careful evaluation and intervention based on these findings to document its effect on pain and dysfunction in AC.

Frozen Shoulder: Diagnosis and Management.

ABSTRACT: Frozen shoulder is a common condition that causes pain and restriction of movement of the shoulder unrelated to secondary causes. It has three classic phases (freezing, frozen, and thawing), and is resolved in most cases within 1 to 2 years. Diagnosis is clinical based on global motion restriction and pain. Imaging plays an ancillary role to narrow the differential diagnosis. Physical therapy, nonsteroidal anti-inflammatories, and injection therapies are standard treatments, although none have been shown to alter the long-term course of the condition. Ultrasound guidance is recommended for injection-based therapy, although not required. Further study should focus on long-term outcomes and treatments that significantly alter the natural course of the disease.

The diagnostic value of physical examination tests in adhesive capsulitis: a systematic review.

INTRODUCTION: Adhesive capsulitis, a condition marked by pain and stiffness of the shoulder, can have a frustrating clinical course for patients and health care professionals. Despite huge research interest, a universally accepted and used definition of clinical criteria for the diagnosis of adhesive capsulitis is currently still lacking. This systematic review aimed to identify diagnostic values for clinical examinations tests used in the diagnosis of adhesive capsulitis. EVIDENCE ACQUISITION: A total of 5 electronic databases (PubMed, Web of Science, Embase, Cochrane Central Register of Controlled Trials [CENTRAL] and PEDro) were searched for relevant studies from 2002 until October 2022 using the terms: "adhesive capsulitis AND diagnosis" and "frozen shoulder AND diagnosis." The Downs and Black Checklist (modified) was used to assess the risk of bias. The study protocol was prospectively registered at the International prospective register of systematic reviews (PROSPERO, CRD42022365993). EVIDENCE SYNTHESIS: The initial database search identified 1799 studies, of which 9 (0.50%) were eventually included in the systematic review. Non-intrusive shoulder range of motion measurements in patients with adhesive capsulitis using the Kinect for Windows (Microsoft, Redmond, WA, USA) showed high correlation with clinical range of motion measurement. Two specific clinical tests, the affected-unaffected shoulder approach of the Coracoid Pain Test and the Distension Test in Passive External Rotation, were identified and presented excellent sensibility and specificity in the diagnosis of adhesive capsulitis, in their original study. Comparison between clinical tests was not possible due to the heterogeneity in clinical tools. CONCLUSIONS: This systematic review identified several physical examination tests developed for the diagnosis of adhesive capsulitis but could not compare them nor advance a set of clinical diagnostic tests that are scientifically validated. Further research is warranted to obtain validation of clinical diagnosis tools for adhesive capsulitis.

Management of Hip Abductor Tears and Recalcitrant Trochanteric Bursitis in Native Hips.

Hip abductor tears have recently gained recognition as a more prevalent injury than previously thought. This article will detail the pathophysiology of injury, physical symptoms commonly found at presentation, diagnostic imaging to best diagnose tears and when they should be ordered, and how to properly classify the injury and finally summarize the treatment options available with expert opinions about which are most successful.

Ultrasound-Guided Infiltrative Treatment Associated with Early Rehabilitation in Adhesive Capsulitis Developed in Post-COVID-19 Syndrome.

Background and Objectives: Post-COVID-19 syndrome is commonly used to describe signs and symptoms that continue or develop after acute COVID-19 for more than 12 weeks. The study aimed to evaluate a treatment strategy in patients with adhesive capsulitis (phase 1) developed in post-COVID-19 syndrome. Materials and Methods: The method used was an interventional pilot study in which 16 vaccinated patients presenting with the clinical and ultrasound features of adhesive capsulitis (phase 1) developed during post-COVID-19 syndrome were treated with infiltrative hydrodistension therapy under ultrasound guidance associated with early rehabilitation treatment. Results: Sixteen patients with post-COVID-19 syndrome treated with ultrasound-guided infiltration and early rehabilitation treatment showed an important improvement in active joint ROM after 10 weeks, especially in shoulder elevation and abduction movements. The VAS mean score before the treatment was 6.9 ± 1.66. After 10 weeks of treatment, the VAS score was 1 ± 0.63. Conclusions: The study demonstrated that the management of adhesive capsulitis (phase 1) developed in post-COVID-19 syndrome, as conducted by physiotherapists in a primary care setting using hydrodistension and a rehabilitation protocol, represented an effective treatment strategy.

Clinical Outcomes After Concomitant Hip Arthroscopy and Iliotibial Band Lengthening With Trochanteric Bursectomy Compared to a Matched Cohort.

PURPOSE: This study sought to determine the clinical outcomes of patients that underwent hip arthroscopy for femoroacetabular impingement (FAI) and concomitant arthroscopic iliotibial (IT) band lengthening with trochan- teric bursectomy (TB group) as well as a matched cohort of patients undergoing hip arthroscopy for isolated FAI symptoms (NTB group) from baseline to a minimum of 2-year follow-up. METHODS: Patients who were diagnosed with FAI and symptomatic trochanteric bursitis and who failed con- servative measures and underwent hip arthroscopy and arthroscopic IT band lengthening with trochanteric bur- sectomy were identified. These patients were matched by age, sex, and body mass index (BMI) to a group of patients who underwent surgery for FAI without trochanteric bur- sitis symptoms. Patients were separated into two groups: iliotibial band lengthening with trochanteric bursectomy (TB) and non-trochanteric bursectomy (NTB). The patient reported outcomes (PROs) recorded were the modified Har- ris Hip Score (mHHS) and Non-Arthritic Hips Score (NAHS), which were obtained with a minimum of 2-years follow-up. RESULTS: Each cohort was composed of 22 patients. The TB cohort was composed of 19 females (86%) with a re- ported mean age of 49.3 ± 11.6 years. The NTB cohort was composed of 19 females (86%) with a reported mean age of 49.0 ± 11.7 years. Both cohorts showed significant improve- ment from baseline in the mHHS and NAHS. There was no significant difference in the mHHS and NAHS between the two groups. There was no significant difference between TB and NTB groups with respect to achieving minimal clinically important difference (MCID), [19 (86%) vs. 20 (91%), p > 0.99] or patient acceptable symptom state (PASS), [13 (59%) vs. 14 (64%), p = 0.76]. CONCLUSIONS: There was no difference in PROs of patients with FAI and trochanteric bursitis who underwent hip ar- throscopy with concomitant arthroscopic IT band lengthen- ing with trochanteric bursectomy compared to patients with isolated FAI who underwent hip arthroscopy.

Is there an association between breast cancer and incident adhesive capsulitis of the shoulder? A retrospective cohort study from Germany.

PURPOSE: Preliminary data suggest that women with breast cancer are at particularly high risk of adhesive capsulitis of the shoulder. Therefore, this study aimed to investigate the potential association between breast cancer and adhesive capsulitis in adults from Germany. METHODS: This retrospective cohort study included all women aged ≥ 18 years who were diagnosed for the first time with breast cancer in one of 1,274 general practices in Germany between January 2000 and December 2018 (index date). Women without breast cancer were matched (1:1) to those with breast cancer using a propensity score based on age at the index date, index year, and the average number of medical consultations per year during the follow-up. In women without breast cancer, the index date was a randomly selected visit date between 2000 and 2018. The association between breast cancer and the 10-year incidence of adhesive capsulitis was studied using Kaplan-Meier curves and a Cox regression model adjusted for age and several comorbidities. RESULTS: There were 52,524 women included in this study (mean [SD] age 64.2 [12.9] years). The 10-year incidence of adhesive capsulitis was 3.6% in both the group with and the group without breast cancer (log-rank p-value = 0.317). The Cox regression analysis further showed no significant association between breast cancer and adhesive capsulitis (HR = 0.96, 95% CI = 0.86-1.08). CONCLUSION: In this sample of women from Germany, breast cancer was not significantly associated with adhesive capsulitis. Although the present preliminary findings are reassuring, general practitioners should regularly assess shoulder function in breast cancer survivors.
