The value of radiographic markers in the diagnostic work-up of rotator cuff tears, an arthroscopic correlated study

Objective To evaluate the value of radiographs during the diagnostic work-up of rotator cuff tears, using arthroscopy as reference standard. Materials and methods This retrospective study included 236 shoulders of 236 patients. All radiographs were evaluated for inferior cortical acromial sclerosis, lateral acromial spur, superior migration of the humeral head, greater tubercle cysts, and subacromial space calcifications. Predictive value of these radiographic signs in predicting rotator cuff tears was determined with arthroscopy as reference standard. Results According to arthroscopy, 131 shoulders were diagnosed with rotator cuff tears. Seventy-two out of 131 shoulders (55%) had inferior cortical acromial sclerosis, 37 (28%) lateral acromial spur, 21 (16%) superior migration of the humeral head, 7 (5%) greater tubercle cysts and 15 subacromial space calcifications (11%). Inferior cortical acromial sclerosis (P = 0.001), lateral spur (P = 0.001), superior migration (P = 0.002), and cysts (P = 0.03) were significantly and independently associated with rotator cuff tears, whereas subacromial calcifications (p = 0.21) was not. Inferior cortical acromial sclerosis, superior migration, lateral acromial spur, and cysts combined have a positive predictive value of 78%. Conclusions The combination of inferior cortical acromial sclerosis, lateral acromial spur, superior migration of the humeral head, and greater tubercle cysts has a high positive predictive value for the presence of full-thickness rotator cuff tears. In patients with a high suspicion for having a rotator cuff tear based on radiographic findings, MRI can be performed directly without the delay and costs caused by an additional ultrasound exam

Developmeent of a Prognostic Model for Patients With Shoulder Complaints in Physical Therapist Practice

BACKGROUND: Health care providers need prognostic factors to distinguish between patients who are likely to recover and those who are not likely to recover. OBJECTIVE: The aim of this study was to: (1) describe the clinical course of recovery and (2) identify prognostic factors of recovery in patients with shoulder pain at the 26-week follow-up. DESIGN: A prospective cohort study was carried out in the Netherlands and included 389 patients who consulted a physical therapist for a new episode of shoulder pain. METHOD: Participants were followed for 26 weeks. Potential predictors of recovery were selected from the literature and, with the addition of 2 new variables (ie, use of diagnostic ultrasound and working alliance), evaluated in the multivariable regression analysis. Multiple imputation was used to handle missing data, and bootstrap methods were used for internal validation. RESULTS: The recovery rate was 60% for the total population and 65% for the working population after 26 weeks. Short duration of complaints, lower disability scores, having a paid job, better working alliance, and no feelings of anxiety or depression were associated with recovery. In the working population, only duration of complaints and disability remained in the final model. The area under the receiver operating characteristic curve (AUC) for the final model was 0.67 for the total population and 0.63 for the working population. After internal validation, the AUC was corrected to 0.66 and 0.63, respectively. LIMITATIONS: External validation of the prognostic model should be done prior to its use in clinical practice. CONCLUSION: The results of this study indicate that several factors can predict recovery

Current management and prognostic factors in physiotherapy practice for patients with shoulder pain: design of a prospective cohort study

BACKGROUND: Shoulder pain is disabling and has a considerable socio-economic impact. Over 50% of patients presenting in primary care still have symptoms after 6 months; moreover, prognostic factors such as pain intensity, age, disability level and duration of complaints are associated with poor outcome. Most shoulder complaints in this group are categorized as non-specific. Musculoskeletal ultrasound might be a useful imaging method to detect subgroups of patients with subacromial disorders. This article describes the design of a prospective cohort study evaluating the influence of known prognostic and possible prognostic factors, such as findings from musculoskeletal ultrasound outcome and working alliance, on the recovery of shoulder pain. Also, to assess the usual physiotherapy care for shoulder pain and examine the inter-rater reliability of musculoskeletal ultrasound between radiologists and physiotherapists for patients with shoulder pain. METHODS: A prospective cohort study including an inter-rater reliability study. Patients presenting in primary care physiotherapy practice with shoulder pain are enrolled. At baseline validated questionnaires are used to measure patient characteristics, disease-specific characteristics and social factors. Physical examination is performed according to the expertise of the physiotherapists. Follow-up measurements will be performed 6, 12 and 26 weeks after inclusion. Primary outcome measure is perceived recovery, measured on a 7-point Likert scale. Logistic regression analysis will be used to evaluate the association between prognostic factors and recovery. DISCUSSION: The ShoCoDiP (Shoulder Complaints and using Diagnostic ultrasound in Physiotherapy practice) cohort study will provide information on current management of patients with shoulder pain in primary care, provide data to develop a prediction model for shoulder pain in primary care and to evaluate whether musculoskeletal ultrasound can improve prognosis
