Importance Shoulder pain is a common and disabling condition most often managed in primary care. This review provides an evidence-based update on the diagnosis and management of shoulder pain to support clinical decision-making and improve patient outcomes.

Observations Shoulder pain arises from benign, self-limiting soft-tissue disorders or rare but serious causes. In primary care, most cases are nontraumatic and involve periarticular soft tissues. The subacromial region is the most frequent source of pain, and the term subacromial pain is preferred over overlapping and inconsistently defined labels such as rotator cuff tendinopathy or tear, impingement syndrome, or subacromial bursitis. Less commonly, pain originates from the glenohumeral joint, as in glenohumeral osteoarthritis or adhesive capsulitis. Assessment should focus on a detailed history and physical examination to assess pain patterns and movement limitation and to exclude serious causes, such as infection, malignant neoplasm, or nonshoulder referred pain. Once these are excluded, first-line treatment is similar for most patients and aligns with recommended care for other regional musculoskeletal concerns: education about the favorable natural history, symptom relief and activity modification if needed, and watchful waiting. Early imaging is not indicated in the absence of significant trauma or suspicious features, such as fever, unexplained weight loss, or history of malignant neoplasm, as structural abnormalities often do not correlate with symptoms, rarely alter management, and may lead to overdiagnosis and overtreatment. Specialist referral should be reserved for suspected serious pathology, such as infection, malignant neoplasm, fracture, or dislocation; significant functional or neurologic deficit; features suggestive of systemic inflammatory disease; or persistent or worsening pain and debility. High-certainty evidence indicates that subacromial pain does not benefit from surgical intervention.

Conclusions and Relevance Shoulder pain is the third most common musculoskeletal presentation in primary care. Although causes vary, the initial management is largely the same once serious conditions have been excluded. Most patients with subacromial pain will fully recover with minimal intervention and can be safely treated with supportive care. Imaging and referral to surgical subspecialists should be reserved for rare and carefully selected cases to avoid unnecessary intervention.

A Simplified Approach to Evaluate and Manage Shoulder Pain

With the lifetime prevalence of shoulder pain approaching 70%, accurate diagnosis and management remains essential. The shoulder is a complex joint with a vast range of motion making it susceptible to injury due to limited bony stabilization. This manuscript shares a simplified, novel approach to evaluating and managing atraumatic shoulder pain based on triaging symptoms on presence or loss of range of motion. In patients with loss of active and passive range of motion, the likely etiologies of pain include adhesive capsulitis or glenohumeral joint arthritis depending on imaging. In patients with preserved active and passive range of motion, implementing specific special testing can help pinpoint the diagnosis, and further guide appropriate management. Ultrasound plays an increasingly key role in diagnosing and managing shoulder pathology.

mportance: There are a myriad of available treatment options for patients with frozen shoulder, which can be overwhelming to the treating health care professional.

Objective: To assess and compare the effectiveness of available treatment options for frozen shoulder to guide musculoskeletal practitioners and inform guidelines.

Data sources: Medline, EMBASE, Scopus, and CINHAL were searched in February 2020.

Study selection: Studies with a randomized design of any type that compared treatment modalities for frozen shoulder with other modalities, placebo, or no treatment were included.

Data extraction and synthesis: Data were independently extracted by 2 individuals. This study followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline. Random-effects models were used.

Main outcomes and measures: Pain and function were the primary outcomes, and external rotation range of movement (ER ROM) was the secondary outcome. Results of pairwise meta-analyses were presented as mean differences (MDs) for pain and ER ROM and standardized mean differences (SMDs) for function. Length of follow-up was divided into short-term (≤12 weeks), mid-term (>12 weeks to ≤12 months), and long-term (>12 months) follow-up.

Results: From a total of 65 eligible studies with 4097 participants that were included in the systematic review, 34 studies with 2402 participants were included in pairwise meta-analyses and 39 studies with 2736 participants in network meta-analyses. Despite several statistically significant results in pairwise meta-analyses, only the administration of intra-articular (IA) corticosteroid was associated with statistical and clinical superiority compared with other interventions in the short-term for pain (vs no treatment or placebo: MD, -1.0 visual analog scale [VAS] point; 95% CI, -1.5 to -0.5 VAS points; P < .001; vs physiotherapy: MD, -1.1 VAS points; 95% CI, -1.7 to -0.5 VAS points; P < .001) and function (vs no treatment or placebo: SMD, 0.6; 95% CI, 0.3 to 0.9; P < .001; vs physiotherapy: SMD 0.5; 95% CI, 0.2 to 0.7; P < .001). Subgroup analyses and the network meta-analysis demonstrated that the addition of a home exercise program with simple exercises and stretches and physiotherapy (electrotherapy and/or mobilizations) to IA corticosteroid may be associated with added benefits in the mid-term (eg, pain for IA coritocosteriod with home exercise vs no treatment or placebo: MD, -1.4 VAS points; 95% CI, -1.8 to -1.1 VAS points; P < .001).

Conclusions and relevance: The findings of this study suggest that the early use of IA corticosteroid in patients with frozen shoulder of less than 1-year duration is associated with better outcomes. This treatment should be accompanied by a home exercise program to maximize the chance of recovery.
