RESUMEN
INTRODUCTION: There is no recognised terminology, nor diagnostic criteria, for patients with subacromial pain syndrome (SAPS). This is likely to cause heterogeneity across patient populations. This could be a driver of misconceptions and misinterpretations of scientific results. We aimed to map the literature regarding terminology and diagnostic criteria used in studies investigating SAPS. MATERIALS AND METHODS: Electronic databases were searched from inception to June 2020. Original peer-reviewed studies investigating SAPS (also known as subacromial impingement or rotator cuff tendinopathy/impingement/syndrome) were eligible for inclusion. Studies containing secondary analyses, reviews, pilot studies and studies with less than 10 participants were excluded. RESULTS: 11 056 records were identified. 902 were retrieved for full-text screening. 535 were included. 27 unique terms were identified. Mechanistic terms containing 'impingement' are used less than before, while SAPS is used increasingly. For diagnoses, combinations of Hawkin's, Neer's, Jobe's, painful arc, injection test and isometric shoulder strength tests were the most often used, though this varied considerably across studies. 146 different test combinations were identified. 9% of the studies included patients with full-thickness supraspinatus tears and 46% did not. CONCLUSION: The terminology varied considerably across studies and time. The diagnostic criteria were often based on a cluster of physical examination tests. Imaging was primarily used to exclude other pathologies but was not used consistently. Patients with full-thickness supraspinatus tears were most often excluded. In summary, studies investigating SAPS are heterogeneous to an extent that makes it difficult, and often impossible, to compare studies.

PURPOSE: Subacromial impingement syndrome (SIS) is associated with low self-reported shoulder function, impairments in shoulder strength and range of motion (ROM), and pain. It is not known how the symptomatology associated with SIS is reflected in the choice of treatment. This study compares self-reported shoulder function, shoulder strength, ROM, and pain in patients with SIS considered candidates and non-candidates for subacromial decompression (SAD). METHOD: Self-reported shoulder function (Q-DASH and SPADI), maximum isometric muscle strength in shoulder abduction (Abd-strength) and external rotation (ER-strength), active abduction ROM (Abd-ROM) and passive internal rotation ROM (IR-ROM) were measured in a consecutive cohort of patients with SIS referred to an orthopedic outpatient clinic. Additionally, pain during each test and pain levels during the last week were reported. Patients were categorized as candidates or non-candidates for SAD based on their consultation with an orthopedic specialist blinded to test results and self-reported shoulder function. All outcomes and age, gender, weight and duration of symptoms were compared using the unpaired t test or Mann-Whitney's U test as appropriate. RESULTS: One-hundred and fifty-seven patients were included. 25 patients were candidates for SAD, while 132 were not. SAD candidates had significantly lower Abd-ROM (87° vs. 112°, p = 0.011, effect size = 0. 15) and IR-ROM (114° vs. 123°, p = 0.026, effect size = 0.58) additional to higher pain during test of Abd-strength (5.3 vs. 3.7, p = 0.02, effect size = 0.21). No other differences were found between the groups. CONCLUSION: A decrease in abduction and internal rotation range of motion, and increased pain during maximal abduction strength effort are associated with being considered a candidate for subacromial decompression, while self-reported shoulder function, pain during the last week, and rotator cuff strength are not. As SAD candidates primarily differentiates from non-candidates by having more pronounced ROM deficits, it might be important to address ROM in pre- and postsurgical evaluations, but as the overall differences between the two groups seem minor, the relation between impairments and the choice of treatment needs further clarification. LEVEL OF EVIDENCE: IV.

Background: A clavicle fracture often changes the mechanical axes of the shoulder girdle due to displacement and shortening, potentially leading to scapular protraction and decreased subacromial space. If protraction of the scapula is a major risk factor for developing subacromial pain syndrome (SAPS), a previous clavicle fracture could increase the risk of later SAPS. The purpose of this study was to investigate if a previous clavicle fracture correlates with a higher occurrence or earlier diagnosis of SAPS. Methods: In this retrospective case-control study with data from the Danish National Patient Register, all persons aged 18-60 years, with any hospital contact due to a clavicle fracture (DS420) between January 1, 1996, and December 31, 2005, were identified as cases. For each case, five controls, matched on age and sex, were identified. Primary outcome was the first hospital contact with a SAPS diagnosis (DM751-755) registered more than 180 days following the fracture. Follow-up was until November 01, 2021. Results: 21.973 cases and 109.865 controls were included. The incidence of clavicle fractures was 76 fractures per 100.000 persons per year. Twenty-three percent were female. 1.640 (7.46%) cases and 8.072 (7.35%) controls received a SAPS diagnosis within the following 15-25 years, demonstrating no significant difference in the occurrence of SAPS (P = .56). The mean time from fracture to SAPS diagnosis was shorter for cases compared to controls (4040 vs. 4442 days, P < .001), and cases were slightly younger when receiving the diagnosis (51.3 vs. 53.6 years, P < .001). 1614 cases underwent surgical fixation. This subgroup had a statistically significant higher occurrence of later SAPS diagnosis (205 cases, 13%, P < .001). Conclusions: Persons with a previous clavicle fracture did not have an increased occurrence of receiving a SAPS diagnosis compared to matched controls. However, the diagnosis was given 1-2 years earlier for people with a previous fracture. Based on these findings, no strong argument for protraction of the scapula as a major risk factor for the development of SAPS was found.
RESUMEN
INTRODUCTION: Ultrasound measures of subacromial structures are reliable in the hands of experienced sonographers, but it remains unknown if inexperienced clinicians can achieve a satisfactory level of interrater reliability. The aim was to investigate if standardised subacromial ultrasound measures are reliable in the hands of novice sonographers. METHODS: Two novice sonographers performed standardised ultrasound measures on patients diagnosed with subacromial pain syndrome and asymptomatic shoulders. The measures were: supraspinatus tendon thickness (SUPRA), subacromial bursa thickness (SASD), acromio-humeral distance (AHD) and dynamic impingement (DI). Reliability and agreement were evaluated by intraclass correlation coefficient (ICC (2.1)), standard error of measurement, minimal detectable change, 95% limits of agreement, Bland-Altman plots and Cohen's unweighted κ. RESULTS: Twenty-eight patients were recruited (28 symptomatic and 20 asymptomatic shoulders). The ICC of SUPRA ranged from 0.73 to 0.77. The ICC of SASD ranged from 0.41 to 0.88 and AHD from 0.68 to 0.72. Cohen's κ of DI in symptomatic shoulders was 0.29. CONCLUSION: The interrater reliability of novice sonographers was found to be moderate to good when assessing SUPRA and AHD. For SASD and DI, the reliability ranged from poor to good. No significant differences in SUPRA and SASD thickness were found between symptomatic and asymptomatic shoulders. FUNDING: None. TRIAL REGISTRATION: Not relevant.

Morel-Lavallée lesion (MLL) is a closed degloving injury caused by traumatic sheering of subcutaneous tissue from the underlying fascia. MLL can be classified as acute (less-than 3 months) or chronic (greater-than 3 months or if a capsule has formed). Acute lesions are treated with compression, percutaneous aspiration, sclerodesis, suction-curettage or open surgery depending on vitality of the overlying skin, if fractures are present next to the lesion or if infection has occurred. Chronic lesions are treated with sclerodesis, suction-curettage or open surgery. Drain and vacuum-assisted closure placement should be used post-operatively, as argued in this review.

Background: Acromial morphology is an important pathophysiological factor for the development of subacromial impingement syndrome. There are 3 radiological methods to evaluate acromial morphology: Bigliani, modified Epstein, and acromial angle. However, their reliability have not been compared in a single study, nor using standardized radiographs. Consequently, the evaluation of acromial morphology is currently not validated though its widespread use across the world. The objective of this study was to investigate reliability of the 3 known classifications and the novel Copenhagen Acromial Curve classification. Methods: Three experienced clinicians rated 102 standardized supraspinatus outlet view radiographs with the 4 classification methods in 2 separate sessions a month apart. All measurements were blinded. With an expected kappa (κ) and intraclass correlation coefficient (ICC) > 0.7 (+/-0.15), the target sample size was 87 radiographs. Results: The Bigliani classification had interrater and intrarater reliability ranging from fair to good (κ 0.32-0.41 and 0.26-0.62). The modified Epstein classification had fair to good interrater and intrarater reliability (κ 0.24-0.69 and 0.57-0.63). The acromial angle classification had moderate to good interrater and intrarater reliability (κ 0.53-0.60 and 0.59-0.72). The novel Copenhagen Acromial Curve classification showed moderate to good interrater and intrarater reliability (ICC 0.66-0.71 and 0.75-0.78, respectively). Conclusion: The Copenhagen Acromial Curve was the only classification method with an ICC value > 0.7. The popular Bigliani classification had the worst reliability. The Copenhagen Acromial Curve classification produces numerical data, as opposed to the other 3 classification methods. This could potentially be utilized in future research to establishing cut-off values for treatment stratification.
RESUMEN
BACKGROUND: Differences in shoulder-disability among common shoulder-disorders in orthopaedic specialist care is unknown. Furthermore, rating of shoulder-disability using patient-reported outcomes is time-consuming, and a faster approach is needed. OBJECTIVES: First, compare shoulder-disability among common shoulder-disorders. Secondly, rate shoulder-disability according to the new and quick Copenhagen Shoulder Abduction Rating (C-SAR) and investigate criterion validity of C-SAR. METHODS: Cross-sectional study including 325 consecutive patients with shoulder-disorders in orthopaedic specialist care. We assessed shoulder abduction range-of-motion and pain during testing (NRS:0-10), and shoulder-disability using Shoulder Pain and Disability Index (SPADI) subscales. Patients were sub-grouped using C-SAR, which is based on shoulder abduction range-of-motion and pain during testing: Severe (range-of-motion ≤90°), Medium (range-of-motion >90°, NRS:>5), Mild (range-of-motion >90°, NRS:≤5). Shoulder-disability was compared among diagnostic categories and C-SAR subgroups using ANCOVA-models. RESULTS: Most patients were diagnosed with either subacromial impingement (n = 211) or full-thickness/complete rotator-cuff tear (n = 18), but adhesive capsulitis (n = 22) was the diagnostic category related to worst SPADI scores. Data for C-SAR subgrouping were available from 187/229 (82%) patients with rotator-cuff related disorders (subacromial impingement or rotator-cuff tears). C-SAR subgrouping was not feasible for patient with adhesive capsulitis or glenohumeral injury. Differences in shoulder-disability between Mild (n = 67) and Medium (n = 56) C-SAR subgroups were large for both SPADI-subscales (ES: 1.0, p < .0001). Only SPADI-function differed significantly between Severe (n = 64) and Medium C-SAR subgroups (ES: 0.4, p = .017). CONCLUSION: In orthopaedic specialist care, adhesive capsulitis relates to highest level of shoulder-disability, while C-SAR is a promising test to rate shoulder-disability for most patients, namely those with rotator-cuff related disorders.

Subacromial impingement syndrome is one of the most common causes of shoulder pain and is associated with substantial shoulder impairments. The initial treatment should be non-operative in form of rotator cuff and scapula strengthening exercises for at least three months. Not all patients respond satisfactorily to non-operative treatment, but only patients with persistent symptoms after sufficiently tried non-operative treatment, should be referred to an orthopaedic specialist.

Tendinopathy is a condition of tendon overuse and is a very common cause of morbidity among recreational and competitive athletes. Chronic overload results in degenerative changes of the tendon, which becomes painful and swollen with impaired function. A reduction in the overloading activity is the mainstay of the treatment. A rehabilitating programme consisting of controlled loading of the affected tendon should follow this. Other modalities, which may facilitate treatment, are: injections with corticosteroid, platelet-rich plasma, and of high volume, as well as shock-wave therapy and surgery.

BACKGROUND: Impaired patient-reported shoulder function and pain, external-rotation strength, abduction strength, and abduction range-of-motion (ROM) is reported in patients with subacromial impingement (SIS). However, it is unknown how much strength and ROM improves in real-life practice settings with current care. Furthermore, outcomes of treatment might depend on specific rehabilitation parameters, such as the time spent on exercises (exercise-time), number of physiotherapy sessions (physio-sessions) and number of corticosteroid injections, respectively. However, this has not previously been investigated. The purpose of this study was to describe changes in shoulder strength, ROM, patient-reported function and pain, in real-life practice settings, and explore the association between changes in clinical core outcomes and specific rehabilitation parameters. METHODS: Patients diagnosed with SIS at initial assessment at an outpatient hospital clinic using predefined criteria's, who had not undergone surgery after 6 months, were included in this prospective cohort study. After initial assessment (baseline), all patients underwent treatment as usual, with no interference from the investigators. The outcomes Shoulder Pain and Disability Index (SPADI:0-100), average pain (NRS:0-10), external rotation strength, abduction strength and abduction ROM, pain during each test (NRS:0-10), were collected at baseline and at six month follow-up. Amount of exercise-time, physio-sessions and steroid-injections was recorded at follow-up. Changes in outcomes were analyzed using Wilcoxon Signed-Rank test, and the corresponding effect sizes (ES) were estimated. The associations between changes in outcomes and rehabilitation parameters were explored using multiple regression analyses. RESULTS: Sixty-three patients completed both baseline and follow-up testing. Significant improvements were seen in SPADI (19 points, ES:0.53, p < 0.001) and all pain variables (median 1-1.5 points, ES:0.26-0.39, p < 0.01), but not in strength and ROM (ES:0.9-0.12, p > 0.2). A higher number of physio-sessions was significantly associated with larger improvements in external rotation strength (0.7 Newton/session, p = 0.046), and higher exercise-time was significantly associated with decrease in average pain (-0.2 points/1,000 min, p = 0.048). DISCUSSION: Patient-reported function and pain improved after six months of current care, but strength and ROM did not improve. This is interesting, as strengthening exercises is part of most current interventions. While two significant associations were identified between self-reported rehabilitation parameters and outcomes, the small gains per physio-session or 1,000 min of exercise-time reduces the clinical relevance of these relationships. Collectively, the findings from this study indicate room for improvement of the current rehabilitation of SIS, especially with regard to core clinical outcomes, such as strength and range of motion.
