Abstract
Calcific tendinopathy is characterized by the deposition of calcium hydroxyapatite crystals in various tendons of the body. Terms like calcium tendinitis, tendinosis, and tendinopathy are used interchangeably. Calcific tendinopathy is a common and well-documented ailment in the literature. Although common, the natural history, aetiology, and progression of calcific tendinitis are poorly understood. The treatment options include conservative and interventional measures. However, these measures cannot be applied as a blanket and are often tailored depending on the stage/phase of the disease. Out of the recognized stages of the disease, the resorptive stage causes the utmost symptoms when the calcium is rather soft and unstable. During this stage, the calcium may migrate beyond expected resorption and get deposited in the adjacent tissues contiguous with the calcium focus. The common destinations include bursal migration, intraosseous migration, muscular migration, and other less common migration sites. Such atypical presentations can lead to dilemmas in the diagnosis, prolongation of the diagnostic pathway, unwarranted apprehension, and treatment delay. Radiologists' role in this situation is to correctly recognize the imaging findings of atypical presentations of calcific tendinopathy and prevent unnecessary diagnostic and interventional studies. In this review article, we describe the pathogenic pathway and natural history of calcific tendinopathy from a radiologist's perspective and discuss different migratory patterns of calcium in calcific tendinopathy not only around the shoulder but also in other areas of the body on different imaging modalities. We also show a few examples of mimics and pitfalls on imaging. Finally, we discuss the appropriate management option of this condition.

Abstract
Background Rotator cuff calcific tendinitis (RCCT) is a commonly occurring disease, with a prevalence of up to 42.5% in patients with shoulder pain1,2. RCCT is characterized by hydroxyapatite deposits in the tendons of the rotator cuff and is considered a self-limiting disease that can be treated nonoperatively3. However, in a substantial group of patients, RCCT can have a very disabling and long-lasting course1,4, requiring additional treatment. Ultrasound-guided percutaneous needling and lavage (i.e., barbotage) is a safe and effective treatment option for RCCT5. In the present article, we focus on the 1-needle barbotage technique utilized in combination with an injection of corticosteroids in the subacromial bursa. Description It must be emphasized that symptomatic RCCT should be confirmed before barbotage is performed. Therefore, we recommend a diagnostic ultrasound and/or physical examination prior to the barbotage. Barbotage is performed under ultrasound guidance with the patient in the supine position. After sterile preparation and localization of the calcified deposit(s), local anesthesia in the soft tissue (10 mL lidocaine 1%) is administered. Next, the subacromial bursa is injected with 4 mL bupivacaine (5 mg/mL) and 1 mL methylprednisolone (40 mg/mL) with use of a 21G needle. The deposit(s) are then punctured with use of an 18G needle. When the tip of the needle is in the center of the deposit(s), they are flushed with a 0.9% saline solution and the dissolved calcium re-enters the syringe passively. This process is repeated several times until no more calcium enters the syringe. In the case of solid deposits, it may not be possible to aspirate calcium; if so, an attempt to fragment the deposits by repeated perforations, and thus promote resorption, can be made. Postoperatively, patients are instructed to take analgesics and to cool the shoulder. Alternatives RCTT can initially be treated nonoperatively with rest, nonsteroidal anti-inflammatory drugs, and/or physiotherapy3. If the initial nonoperative treatment fails, extracorporeal shockwave therapy (ESWT), corticosteroid injections, and/or barbotage can be considered8. In severe chronic recalcitrant cases, arthroscopic debridement and/or removal can be performed as a last resort. Rationale Both barbotage and ESWT result in a reduction of calcific deposits, as well as significant pain reduction and improvement of function8. No standard of care has been established until now; however, several prior meta-analyses concluded that barbotage is the most effective treatment option, with superior clinical outcomes after 1 to 2 years of follow-up9-11. No difference in complication rates has been reported between the various minimally invasive techniques. The purpose of barbotage is to stimulate the resorption process, which is promoted by the perforation of the deposits. Clinical outcomes are not associated with the success of the aspiration7,12. Patients with ≥1 larger deposit show greater improvement following barbotage than patients with small deposits12, in contrast with ESWT, in which larger deposits have been associated with worse outcomes. The inferior outcome of barbotage in patients with small deposits remains the subject of debate, but outcomes may be confounded by the fact that patients with smaller deposits might be less symptomatic at baseline and are therefore less likely to demonstrate improvement4. Expected Outcomes In the first weeks after barbotage, there is generally a substantial reduction in symptoms. Symptoms can recur at around 3 months, presumably because the effect of the corticosteroids is temporary5. After 6 months and 1 year, patients show substantial improvement in pain, shoulder function, and quality of life, with results superior to those shown for subacromial injections and ESWT9,10,13,14. At 5 years postoperatively, there are no significant differences in outcomes between barbotage and subacromial injections15. This may demonstrate a self-limiting course in the long term. Important Tips Good candidates for barbotage are those with RCCT who have ≥1 large calcific deposit.If a patient has a solid deposit, the physician can gently rotate and repeatedly puncture the deposit to promote disaggregation and fragmentation.Barbotage generally results in adequate pain relief and functional improvement even in patients in whom calcium deposits cannot be aspirated12.

Calcific Tendinopathy of the Shoulder: A Retrospective Comparison of Traditional Barbotage Versus Percutaneous Ultrasonic Barbotage. Clin J Sport Med 2022; 32:458-466. [PMID: 35533134 DOI: 10.1097/jsm.0000000000001039] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/20/2021] [Accepted: 03/21/2022] [Indexed: 02/02/2023]
Abstract
OBJECTIVE The purpose of this study was to compare a traditional barbotage technique with percutaneous ultrasonic barbotage (PUB) for the treatment of rotator cuff (RC) calcific tendinopathy. DESIGN Three-year retrospective review. SETTING Participants aged 18 to 75 presenting at 2 highly specialized outpatient orthopedic referral centers with symptomatic RC calcific tendinopathy. PATIENTS There were 75 patients included (23 patients in the traditional barbotage group; 52 patients in the PUB group) with an average age of 55.3(6.5) and 55.9(9.8), respectively. There was no significant difference in demographics between groups. INTERVENTIONS Traditional barbotage or PUB. MAIN OUTCOME MEASURES Primary outcome measure was pain rated on the Numeric Pain Rating Scale (NPRS) with secondary outcomes investigating patient satisfaction. RESULTS The barbotage and PUB group demonstrated a significant improvement in pain (barbotage 2.4, P = 0.01; PUB = 2.6, P < 0.001) with no statistically significant difference between the 2 treatment modalities (95% CI: -1.8 to 2.2; P = 0.83, P = 0.83). Median follow-up for NPRS recordings was 17-weeks in the barbotage group and 8-weeks in the PUB group ( P = 0.004). Both groups demonstrated similar patient-reported satisfaction, without major complications. CONCLUSION The traditional barbotage and PUB procedures improved pain with a high patient satisfaction rate. LEVEL OF EVIDENCE Level III.

Intraosseous calcific tendinitis of the rotator cuff yields similar outcomes to those of intratendinous lesions despite worse preoperative scores. Knee Surg Sports Traumatol Arthrosc 2022; 30:2485-2491. [PMID: 35044474 DOI: 10.1007/s00167-022-06870-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/23/2021] [Accepted: 01/05/2022] [Indexed: 10/19/2022]
Abstract
PURPOSE To evaluate the surgical outcomes of arthroscopic removal of intraosseous deposits in patients with intraosseous calcific tendinitis of the rotator cuff. METHODS This study involved a retrospective review of 96 patients operated on from 2004 to 2019. Patients were divided into two groups according to the location of calcific deposits. Group I had pure tendinous involvement (n = 71), and Group II had tendinous and intraosseous involvement (n = 25). The mean follow-up time was 6.4 ± 3.9 years. There were 71 patients (46 women, 25 men) in Group I, and the mean age was 49.3 ± 8.2 years (range 30-65 years). In group II, there were 25 patients (18 women, 7 men); the mean age was 47.3 ± 11.2 years (range 28-70 years). RESULTS The mean preoperative VAS pain score was 8.8 ± 1.4 in Group I compared to 9.5 ± 0.5 in group II (p = 0.017). The median preoperative Constant and Oxford scores were 42 (20-65) and 22 (8-34) in Group I and 25.5 (22-46) and 10 (8-16) in group II, respectively (p < 0.001). There was no difference in postoperative pain scores (Group I: 0.7 ± 1.6 and group II: 0.5 ± 0.6, p = 0.926), Constant scores [Group I: 100 (80-100) and group II: 100 (90-100), (n.s).] and Oxford scores [Group I: 48 (28-48) and group II: 46.5 (4-48), (n.s.)] between the two groups. The number of preoperative injections was higher in Group II (p = 0.05). There was no correlation between the size of the soft tissue calcific deposit and the preoperative pain, Constant, and Oxford scores (n.s.). CONCLUSION Arthroscopic debridement of calcific tendinitis with intraosseous involvement is a safe and effective treatment method similar to that of pure tendinous involvement. LEVEL OF EVIDENCE III.

Abstract
OBJECTIVE To evaluate the performance of two machine learning models in predicting the long-term complete pain resolution in patients undergoing ultrasound-guided percutaneous irrigation of calcific tendinopathy (US-PICT). MATERIALS AND METHODS Within a 3-year period, 100 consecutive patients who underwent US-PICT for rotator cuff disease were prospectively enrolled. The location, maximum diameter, and type of each calcification were recorded. The degree of calcium retrieval was graded as complete or incomplete. Shoulder pain was assessed with the visual analogue scale (VAS) at baseline, 1-week, 1-month, and 1-year post-treatment. Measurements related to procedural details, patient, and calcification characteristics were used to construct a machine learning model for the prediction of pain at 1-year post-US-PICT. Two distinct models were built, one including VAS data at 1 week and another additionally including pain data at 1-month post-treatment. Variable importance analysis was performed for the 1-week model. Model performance was evaluated by using receiver operating characteristics (ROC) curves and the respective areas under the curve (AUC). RESULTS The model exhibited an AUC of 69.2% for the prediction of complete pain resolution at 1 year. The addition of VAS scores at 1 month did not significantly alter the performance of the algorithm. Age and baseline VAS scores were the most important variables for classification performance. CONCLUSION The presented machine learning model exhibited an AUC of almost 70% in predicting complete pain resolution at 1 year. Pain data at 1 month do not appear to improve the performance of the algorithm.

Abstract
Background Although ultrasound-guided needle decompression (US-GND) can treat calcific tendinitis of the shoulder effectively, repeat procedures might be required for unresolved symptoms. We evaluated the overall clinical outcomes of US-GND with subacromial steroid injection and the final results and factors predisposing toward repeat procedures. Methods Ninety-eight patients who underwent US-GND for calcific tendinitis of the supraspinatus/infraspinatus were analyzed between March 2017 and December 2018. The clinical outcomes (pain visual analog scale, functional visual analog scale [FVAS], and American Shoulder and Elbow Surgeons [ASES] score) and final subjective satisfaction were compared between groups A (single US-GND) and B (repeat US-GND). The factors predisposing toward repeated US-GNDs were analyzed. Results We found that 59.3% (58/98) of patient ASES scores were ≥80, and 73.5% of patients (72/98) were satisfied with the outcome. Group B (n=14) demonstrated a significantly higher rate of dominant-arm involvement compared to group A (78.6% vs. 48.8%, p=0.046). However, initial calcification size, shape, number, density, subscapularis involvement, lavage, and procedure time did not differ significantly between the groups. Group B showed poorer final FVAS (7 [interquartile range, 6–8] vs. 8 [interquartile range, 7–9], p=0.036) and subjective satisfaction compared to group A (satisfied: 5 [35.7%] vs. 67 [79.8%], p<0.001]. Conclusions US-GND with subacromial steroid injection is a viable treatment option for calcific tendinitis of the shoulder. Dominant-arm involvement was the only independent factor for repeated US-GND. Final outcome of repeated US-GND for unimproved patients was promising; however, these outcomes were poor compared to those of the patients who improved after the first procedure.

Abstract
BACKGROUND Calcific tendinitis of the rotator cuff is a frequent cause of shoulder pain. Ultrasound-guided percutaneous lavage (UGPL) is an effective treatment, but factors associated with good clinical and radiological outcomes still need to be identified. PURPOSE To study the clinical, procedural, and radiological characteristics associated with improved shoulder function and the disappearance of calcification on radiograph after UGPL. STUDY DESIGN Case-control study; Level of evidence, 3. METHODS This is a post hoc analysis of the CALCECHO trial, a double-blinded randomized controlled trial conducted on 132 patients. The trial assessed the effect of corticosteroid injections after UGPL, and patients were randomly assigned to receive either corticosteroid or saline solution in the subacromial bursa. We analyzed all patients included in the randomized controlled trial as 1 cohort. We collected the patients' clinical, procedural, and radiological characteristics at baseline and during follow-up (3, 6, and 12 months). Univariable analysis, followed by multivariable stepwise regression through forward elimination, was performed to identify the factors associated with clinical success (Disabilities of the Arm, Shoulder and Hand [DASH] score <15) or the disappearance of calcification. RESULTS Good clinical outcomes at 3 months were associated with steroid injections after the procedure (odd ratio [OR], 3.143; 95% CI, 1.105-8.94). At 6 months, good clinical evolution was associated with a lower DASH score at 3 months (OR, 0.92; 95% CI, 0.890-0.956) and calcium extraction (OR, 10.7; 95% CI, 1.791-63.927). A lower DASH at 6 months was also associated with a long-term favorable outcome at 12 months (OR, 0.939; 95% CI, 0.912-0.966). Disappearance of calcification at 3 and 12 months occurred more frequently in patients in whom communication was created between the calcification and the subacromial bursa during the procedure (OR, 2.728 [95% CI, 1.194-6.234] at 3 months; OR, 9.835 [95% CI, 1.977-48.931] at 12 months). Importantly, an association between calcification resorption and good clinical outcome was found at each time point. CONCLUSION Assessing patients at 3 months seems to be an essential part of their management strategy. Calcium extraction and creating a communication between the calcific deposits and subacromial bursa are procedural characteristics associated with good clinical and radiological evolution.

Abstract
BACKGROUND Needle aspiration of calcific deposits (NACD) is a frequently used treatment for rotator cuff calcific tendinitis (RCCT). However, a substantial number of patients experience recurrent or persisting shoulder symptoms after NACD. PURPOSE To compare the effects of adjuvant application of platelet-rich plasma (PRP) after NACD (NACP+PRP) with those of conventional NACD with corticosteroids (NACD+corticosteroids) on pain, shoulder function, and quality of life (QoL). STUDY DESIGN Randomized controlled trial; Level of evidence, 1. METHODS In a single-center, double-blinded, randomized controlled trial, 80 adults with symptomatic RCCT were randomly allocated to receive NACD+corticosteroids or NACD+PRP. Pain, shoulder function, and QoL were assessed at baseline; 6 weeks; and 3, 6, 12, and 24 months after treatment using a numeric rating scale for pain (NRS); the Constant-Murley score (CMS); the Disabilities of the Arm, Shoulder and Hand questionnaire (DASH); the Oxford Shoulder Score (OSS); and the EuroQol 5-dimension scale (EQ-5D). Additionally, resorption of calcific deposits and the integrity of rotator cuff tendons were assessed by using standard radiographs and ultrasound examination, respectively. The results were analyzed using noninferiority analysis for NRS scores and a mixed model for repeated measures. RESULTS Eighty patients were included (48 female; mean age, 49 ± 6 years; 41 patients in the NACD+PRP group). Both groups showed improvement of clinical scores at the 2-year follow-up (P < .001 for all clinical scores). NACD+PRP was found to be noninferior to NACD+corticosteroids with regard to the mean decrease of NRS scores (4.34 vs 3.56; P = .003). Mixed-model analysis showed a significant difference in favor of NACD+PRP (CMS, P < .001; DASH, P = .002; OSS, P = .010; EQ-5D, P < .001). However, clinically relevant differences in favor of NACD+PRP were only seen at the 6-month follow-up for NRS and CMS scores, whereas at the 6-week follow-up a clinically relevant difference in favor of NACD+corticosteroids was found for all clinical scores except for the NRS. Full resorption of calcific deposits was present in 84% of the NACD+PRP group compared with 66% in the NACD+corticosteroids group (P = .081). In the NACD+PRP group, 10 (24%) patients required a second NACD procedure compared with 19 (49%) patients in the NACD+corticosteroids group (P = .036). Six complications, of which 5 were frozen shoulders, occurred in the NACD+PRP group compared with 1 complication in the NACD+corticosteroids group (P = .11). CONCLUSION NACD+PRP resulted in worse clinical scores at the 6-week follow-up but better clinical scores at the 6-month follow-up compared with NACD+corticosteroids. At the 1- and 2-year follow-ups, the results were comparable between groups. Furthermore, PRP seemed to reduce the need for additional treatments but was associated with more complications. In conclusion, NACD+corticosteroids had a favorable early effect on pain and function combined with low comorbidity. Thus, it remains the treatment of choice for patients with RCCT.

Abstract
OBJECTIVES To identify prognostic factors affecting the clinical outcome in patients treated with rotator cuff ultrasound-guided percutaneous irrigation of calcific tendinopathy (US-PICT), by evaluating the degree of calcium removal, the size and consistency of calcific deposits, and baseline level of shoulder pain and functionality. METHODS From January 2017 to December 2019, 79 patients (23 males, 56 females; mean age, 45.7 years) who underwent US-PICT were prospectively enrolled. The calcifications' location, consistency, and size were evaluated. For US-PICT, local anesthesia, lavage of calcific material, and intrabursal steroid injection were performed. The degree of calcium removal was graded as total/partial. Shoulder pain and functionality were assessed with the visual analogue scale (VAS) in all and Constant score (CS) in a subset of patients, respectively, at 4 time-points. Mann-Whitney U test, Fisher's test, and linear and binary logistic regression were utilized for analysis. RESULTS Pain improvement correlated with the presence of larger calcifications and lower baseline VAS score, at 1 week (p = 0.001, p < 0.001, respectively) and 1 year (p < 0.001, p = 0.002, respectively). Improved functionality correlated with total calcification retrieval, higher baseline CS, and fluid/soft calcific consistency at 1 week (p = 0.013, p = 0.003, p = 0.019, respectively). Increased calcification size, cystic appearance, and lower baseline VAS scores independently predicted complete pain resolution at 1 year. CONCLUSION Large calcifications and low-grade pain at baseline correlated with short- and long-term pain improvement. The degree of calcium removal did not impact pain or functional improvement beyond 1 week. Increased calcification size, cystic appearance, and low-grade baseline pain predicted complete pain recovery at 1 year. KEY POINTS • The presence of larger calcifications and lower-grade baseline pain appear to correlate with pain improvement at 1 week and 1 year after ultrasound-guided irrigation of rotator cuff calcific tendinopathy (US-PICT). • Total calcification retrieval, less affected baseline shoulder functionality, and presence of fluid/soft consistency of calcific deposits appear to correlate with improved shoulder functionality at 1 week post-treatment. • Baseline pain intensity and calcifications' morphologic characteristics, but not the degree of calcium retrieval, represent predictors of complete pain recovery at 1 year after US-PICT.
