Misperception of Disease Onset in People with Gradual-Onset Disease of the Upper Extremity

Potential Misinformation in the Official Disability Guidelines About the Diagnosis and Treatment of Rotator Cuff Tendinopathy

OBJECTIVE

We selected statements in the Official Disability Guidelines that had the potential to reinforce misconceptions regarding symptoms from rotator cuff tendinopathy. These statements were revised and presented with the original statement to specialists.

METHODS

Twelve statements regarding rotator cuff tendinopathy were identified as deviating from principles based on ethics, values, and the evidence regarding both pathophysiology and human illness behavior. One hundred fifteen upper extremity surgeons reviewed both original and revised versions of the statements and indicated their preference.

RESULTS

We found that upper extremity surgeons preferred 3 revised statements, 4 Official Disability Guidelines statements, and 5 were rated as neutral between the 2 statements.

CONCLUSIONS

Statements revised for evidence, ethics, and healthy mindset were not preferred by specialists, which may indicate limited awareness about how negative thoughts and distressing symptoms impact human illness.

Prevalence of incidental distal biceps signal changes on magnetic resonance imaging

BACKGROUND

Knowledge of the base rate of signal changes consistent with distal biceps tendinopathy on magnetic resonance imaging (MRI) has the potential to influence strategies for diagnosis and treatment of people that present with elbow pain. The aim of this study is to measure the prevalence of distal biceps tendon signal changes on MRIs of the elbow by indication for imaging.

METHODS

MRI data for 1,306 elbows were retrospectively reviewed for mention of signal change in distal biceps tendon. The reports were sorted by indication.

RESULTS

Signal changes consistent with distal biceps tendinopathy were noted in 197 of 1,306 (15%) patients, including 34% of patients with biceps pain, 14% of patients with unspecified pain, and 8% of patients with a specific non-biceps indication. Distal biceps tendon changes noted on radiology reports were associated with older age, male sex, and radiologists with musculoskeletal fellowship training.

CONCLUSIONS

The finding that distal biceps MRI signal changes consistent with tendinopathy are common even in asymptomatic elbows reduces the probability that symptoms correlate with pathology on imaging. The accumulation of signal changes with age, also independent of symptoms, suggests that tendon pathology persists after symptoms resolve, that some degree of distal biceps tendinopathy is common in a human lifetime, and that tendinopathy may often be accommodated without seeking care. Level of evidence: IV.

Lived experience of people with lateral elbow tendinopathy: a qualitative study from the OPTimisE pilot and feasibility trial

OBJECTIVES

To explore the lived experience of people with lateral elbow tendinopathy (LET) and its impact on everyday life.

DESIGN

Qualitative semi-structured interviews, analysed using thematic analysis.

SETTING

Conducted as part of the mixed-methods OPTimisE pilot and feasibility randomised controlled trial of outpatient physiotherapy patients in the UK.

PARTICIPANTS

17 participants with LET, purposively sampled from the trial to provide representativeness based on age, sex, ethnicity, deprivation index and treatment allocation.

RESULTS

Four themes were identified from the participants' responses: (1) cause of onset-typically symptoms were attributed to: sudden changes in activity, repetitive work or compensating for other musculoskeletal conditions; (2) impact on everyday life-which included substantial impacts on quality-of-life, particularly due to pain disturbing sleep and difficulties performing daily tasks (related to work and hobbies) due to pain, although most reported being able to persevere with work; (3) self-help and understanding of the condition-with uncertainty about the appropriateness and potential harm of online advice and confusion from the diagnostic term 'Tennis Elbow' that non-sporting individuals struggled to relate to; (4) healthcare experiences-the treatments received were highly variable and often perceived as ineffectual.

CONCLUSIONS

For the first time, the lived experience of people from a range of backgrounds suffering from LET has been explored. Findings suggest that people frequently related the cause to a specific activity. They reported substantial impacts on daily tasks, sleep, work and hobbies. People also reported hesitancy to trust online information without formal healthcare advice, were confused by the common label of 'Tennis Elbow', and perceived the wide array of healthcare treatment options they had received to offer false hope and be largely ineffective. This study provides stimulus for clinicians to consider the advice and treatment provided, and whether the messages conveyed reflect the favourable natural history of the condition.

Are the Pathologic Features of Enthesopathy, Tendinopathy, and Labral and Articular Disc Disease Related to Mucoid Degeneration? A Systematic Review

BACKGROUND

Tendinopathy, enthesopathy, labral degeneration, and pathologic conditions of the articular disc (knee meniscus and ulnocarpal) are sometimes described in terms of inflammation or damage, while the histopathologic findings are often consistent with mucoid degeneration. A systematic review of the histopathology of these structures at diverse locations might reconceptualize these diseases as expected aspects of human aging. The potential benefits of this evolution might include healthier patient and clinician mindsets as well as a reduced likelihood of overdiagnosis and overtreatment resulting from greater awareness of base rates of pathology.

QUESTION/PURPOSE

In this systematic review of studies of surgical specimens, we asked: Are there are any differences in the histopathologic findings of structural soft tissue conditions (mucoid degeneration, inflammation, and vascularity) by anatomic site (foot, elbow, or knee) or structure (tendon body, muscle or tendon origin or insertion [enthesis], labrum, or articular disc)?

METHODS

Studies between 1980 and 2021 investigating the histopathologic findings of specimens from surgery for trigger digit, de Quervain tendinopathy, plantar fasciitis, lateral and medial elbow enthesopathy, rotator cuff tendinopathy, posterior tibial tendinopathy, patellar tendinopathy, Achilles tendinopathy, or disease of the hip labrum, ulnocarpal articular disc, or knee meniscus were searched for in the PubMed, EMBASE, and CINAHL databases. Inclusion criteria were the prespecified anatomic location or structure being analyzed histologically and any findings described with respect to inflammation, vascularity, or mucoid degeneration. Studies were excluded if they were nonhuman studies or review articles. Search terms included "anatomy," "pathology," and "histopathology." These terms were coupled with anatomic structures or disorders and included "trigger finger," "de Quervain," "fasciitis, plantar," "tennis elbow," "rotator cuff tendinopathy," "elbow tendinopathy," "patellar tendonitis," "posterior tibial tendon," and "triangular fibrocartilage." This resulted in 3196 studies. After applying the inclusion criteria, 559 articles were then assessed for eligibility according to our exclusion criteria, with 52 eventually included. We recorded whether the study identified the following histopathologic findings: inflammatory cells or molecular markers, greater than expected vascularity (categorized as quantitative count, with or without controls; molecular markers; or qualitative judgments), and features of mucoid degeneration (disorganized collagen, increased extracellular matrix, or chondroid metaplasia). In the absence of methods for systematically evaluating the pathophysiology of structural (collagenous) soft tissue structures and rating histopathologic study quality, all studies that interpreted histopathology results were included. The original authors' judgment regarding the presence or absence of inflammation, greater than expected vascularity, and elements of mucoid degeneration was recorded along with the type of data used to reach that conclusion.

RESULTS

Regarding differences in the histopathology of surgical specimens of structural soft tissue conditions by anatomic site, there were no differences in inflammation or mucoid degeneration, and the knee meniscus was less often described as having greater than normal vascularity. There were no differences by anatomic structure. Overall, 20% (10 of 51) of the studies that investigated for inflammation reported it (nine inflammatory cells and one inflammatory marker). Eighty-three percent (43 of 52) interpreted increased vascularity: 40% (17 of 43) using quantitative methods (14 with controls and three without) and 60% (26 of 43) using imprecise criteria. Additionally, 100% (all 52 studies) identified at least one element of mucoid degeneration: 69% (36 of 52) reported an increased extracellular matrix, 71% (37 of 52) reported disorganized collagen, and 33% (17 of 52) reported chondroid metaplasia.

CONCLUSION

Our systematic review of the histopathology of diseases of soft tissue structures (enthesopathy, tendinopathy, and labral and articular disc) identified consistent mucoid degeneration, minimal inflammation, and imprecise assessment of relative vascularity; these findings were consistent across anatomic sites and structures, supporting a reconceptualization of these diseases as related to aging (senescence or degeneration) rather than injury or activity.

CLINICAL RELEVANCE

This reconceptualization supports accommodative mindsets known to be associated with greater comfort and capability. In addition, awareness of the notable base rates of structural soft tissue changes as people age might reduce overdiagnosis and overtreatment of incidental, benign, or inconsequential signal changes and pathophysiology.

The mind and the hand

Symptoms are determined in large part by mindsets. Feelings of distress and unhelpful thoughts (misinterpretations) of symptoms account for much of the variability in comfort and capability with the severity of the underlying pathophysiology making a more limited contribution. Incorporating this experimental evidence into the daily practice of hand surgery will help us find ways to develop healthy mindsets, to prioritize the alleviation of distress and the gentle redirection of unhelpful thoughts, to avoid unnecessary surgery, and to provide better psychological and social support for people recovering from injury and surgery.

Correlation of defect size with fatty infiltration on MRIs of rotator cuff tendinopathy

Introduction

Sizable rotator cuff defects with limited muscle atrophy and fat replacement may represent acute traumatic ruptures that are less likely to recur after surgery to close the defect, while closure of defects with poor quality muscle are associated with defect recurrence. These distinct lesions are both referred to as tears. We analyzed the relationship between rotator cuff defect size and muscle quality to determine the relative proportion of sizable defects associated with good muscle and factors associated with muscle deterioration.

Material and methods

A cohort of 230 consecutive shoulder MRIs in patients with full-thickness rotator cuff tendon defects, limited acromioclavicular arthrosis (to avoid hindrance of defect measurement), and a duration of symptoms in the radiology report from a large urban center in the United States was evaluated for the measured distance between the supraspinatus tendon edge and the greater tuberosity medial to lateral (coronal plane defect size), anterior to posterior (sagittal plane defect width), and fatty infiltration (Goutallier classification), and atrophy (Warner classification) of the supraspinatus. We sought factors independently associated with fatty infiltration and muscle atrophy in multivariable logistic regression analyses.

Results

Forty-nine of 109 shoulders (45%) with a coronal plane defect >20 mm had reasonable muscle quality as defined by Goutallier grade less than 2 and Warner grade less than 2. Both greater fatty infiltration of the supraspinatus muscle and greater supraspinatus muscle atrophy were associated with older age and greater coronal plane defect size.

Conclusion

The observation that supraspinatus muscle health deteriorates with age and defect size, but nearly half of the largest defects had good muscle, suggests an important distinction between relatively recent traumatic ruptures and old untreated rupture or gradual attrition that may be obfuscated by referring to all lesions as tears.

Recovery After Musculoskeletal Injury: Mental and Social Health

Recovery from injury involves painful movement and activity, painful stretches and muscle strengthening, and adjustment to permanent impairment. Recovery is facilitated by embracing the concept that painful movement can be healthy, which is easier when one has more hope, less worry, and greater social supports and security. Evolution of one's identity to match the new physical status is a hallmark of a healthy outcome and is largely determined by mental and social health factors. When infection, loss of alignment or fixation, and nerve issues or compartment syndrome are unlikely, greater discomfort and incapability that usual for a given pathology or stage of recovery signal opportunities for improved mental and social health. Surgeons may be the clinicians most qualified to make this discernment. A surgeon who has gained a patient's trust can start to noticed despair, worry, and unhelpful thinking such as fear of painful movement. Reorienting people to greater hope and security and a healthier interpretation of the pains associated with the body's recovery can be initiated by the surgeon and facilitated by social workers, psychologist, and physical, occupational and hand therapists trained in treatments that combine mental and physical therapies.

Persistent Shoulder Pain After Vaccine Administration Is Associated with Common Incidental Pathology: A Systematic Review

BACKGROUND

Claims of shoulder injury now account for half of all claims to the Vaccine Injury Compensation Program. Reports from databases of claims or potential adverse events note a relatively high mean age and high prevalences of rotator cuff tendinopathy and adhesive capsulitis-common shoulder problems that might be incidental to vaccination. Published case reports provide much more detail about individual patients than is available in databases. A review of published cases provides an opportunity for more detailed review of symptoms, diagnoses, pathology, treatment, and prognosis. Such a review can better assess the relative likelihood that pathologies associated with new persistent shoulder symptoms after vaccination are coincidental or unique to and caused by vaccine.

QUESTIONS/PURPOSES

Regarding published case reports addressing persistent shoulder pain after vaccination: (1) In what proportion of patients was a specific diagnosis made? (2) What diagnoses were most common? (3) Among patients treated nonsurgically, what proportion resolved, and over what time span did they resolve?

METHODS

In August 2020, we searched PubMed and Embase between 2006 and 2020 using the following search strategy: Search 1: (shoulder dysfunction OR shoulder pain OR shoulder bursitis OR rotator cuff tendonitis OR adhesive capsulitis OR glenohumeral arthritis AND [vaccine OR vaccination OR immunization]); Search 2: (shoulder injury related to vaccine administration or SIRVA). The search was supplemented by reviewing reference lists of identified studies. Inclusion criteria were any detailed report of three or fewer cases involving shoulder pain after vaccine administration. Twenty published reports of 29 patients were identified and assessed by two reviewers independently. One reported glenohumeral joint infection was excluded because the relationship between this type of relatively uncommon, discrete diagnosis and vaccination raises different considerations. We assumed a high risk of bias, although we are not aware of bias assessment tool for case reports. We recorded and summarized patient demographics, symptoms, examination and imaging findings, surgery findings, diagnoses, treatments, and outcomes. Seventy-five percent (21 of 28) of patients were women, with a mean age of 54 ± 19 years. In search of an underlying pathology, at least one diagnostic study was performed in 82% (23 of 28) of patients including radiographs in seven, ultrasound in seven, and MRI in 16 patients (some patients underwent more than one type of imaging). We distinguished specific pathophysiological diagnosis from shoulder pain and stiffness, counted the most common diagnoses among patients a specific diagnosis, and tracked symptom resolution among patients treated nonoperatively.

RESULTS

A specific diagnosis was made in 57% (16 of 28) of patients. Twelve patients had pain and limitation of motion due to pain but no specific pathological diagnosis. The most common specific diagnoses were rotator cuff tendinopathy (9 of 16) and adhesive capsulitis (4 of 16). Less common specific diagnoses included rotator cuff arthropathy (and rheumatoid arthritis) and suspected septic arthritis with nonspecific synovitis on arthroscopy. One patient had transient MRI signal change in the humeral head, which was interpreted as osteonecrosis that resolved in a manner not typical for that diagnosis. Of the 17 patients treated nonsurgically, 15 reported resolution, and two had incomplete symptom resolution with the mean 6-month evaluation period.

CONCLUSION

The observation that persistent shoulder pain after vaccination overlaps with common shoulder pathology-both in large databases as well as in more detailed reports of specific patients as analyzed in this review-establishes a high probability of a coincidental rather than a causal association. In the absence of high-quality experimental evidence of vaccine-specific shoulder pathology, in our opinion, it seems safest and healthiest to assume that perceived shoulder injury related to vaccine administration (SIRVA) is due to misinterpretation of new symptoms from established pathology rather than a new, vaccine-specific pathology.

What are People That Seek Care for Rotator Cuff Tendinopathy Experiencing in Their Daily Life?

This qualitative study sought to answer three questions: What is it like to live with rotator cuff tendinopathy? What are the barriers and facilitators of a healthy lifestyle with an aging shoulder? And, what are the outcomes that matter most to people seeking care for rotator cuff tendinopathy? Patients diagnosed with rotator cuff tendinopathy participated in group discussions using semi-structured guides that focus on diagnosis, daily experiences living with rotator cuff tendinopathy, goals, concerns, and clinical care experiences. A hybrid of initial inductive coding of themes and subsequent deductive consideration of these themes within the capability, comfort, and calm framework was utilized. Themes associated with rotator cuff tendinopathy were less restful sleep, difficulty with work and life transitions, loss of baseline abilities, and limitation in social roles in the capability realm; physical pain, despair, and loneliness in the comfort realm; and lack of direction or progress and feeling uncared for in the calm realm. Barriers identified included: the sense that rotator cuff tendinopathy is something correctable rather than age-associated and the sense that painful activities will make the tendinopathy worse (common misconceptions); tenuous relationships and limited trust with clinicians; loss of hope; and a sense that care is directionless. What matters most to a person seeking specialty care for shoulder pain are feeling that they are getting effective care and not being dismissed; maintaining meaningful activity and life roles; and replacing despair and frustration with hope and progress. Anticipating these needs may facilitate the design of more effective care models.
