Abstract
Background This review examined the role of artificial intelligence (AI) in the diagnosis and management of rotator cuff tears (RCTs). Methods A literature search was conducted in October 2023 using PubMed (MEDLINE), SCOPUS, and EMBASE databases, included only peer-reviewed studies. Relevant articles on AI technology in RCTs. A critical analysis of the relevant literature was conducted. Results AI is transforming RCTs management through faster and more precise identification and assessment using algorithms that facilitate segmentation, quantification, and classification of the RCTs across various imaging modalities. Precise algorithms focusing on preoperative factors to assess RCTs reparability have been developed for personalized treatment planning and outcome prediction. AI also aids in exercise classification and promotes patient adherence during at-home physiotherapy. Despite promising advancements, challenges in data quality and symptom integration persist. Future research should include refining AI algorithms, expanding their integration into various imaging techniques, and exploring their roles in postoperative care and surgical decision-making. Conclusions AI-driven solutions improve diagnostic accuracy and have the potential to influence treatment planning and postoperative outcomes through the automated RCTs analysis of medical imaging. Integration of high-quality datasets and clinical symptoms into AI models can enhance their reliability. Current AI algorithms can also be refined, integrated into other imaging techniques, and explored further in surgical decision-making and postoperative care.

[PMID: 38192965 PMCID: PMC10771931 DOI: 10.7759/cureus.50103] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2023] [Accepted: 12/04/2023] [Indexed: 01/10/2024] Open
Abstract
BACKGROUND AND AIM The prevalent cause of shoulder pain is rotator cuff tears (RCT), which induce profound discomfort and morbidity. Hence, their detection and appropriate management become important to alleviate morbidity and enhance quality of life. Imaging has an important role in the diagnosis of such patients to guide for further management. A wide array of radiological approaches has been explored for the detection of RCT. The study aimed to assess the sensitivity (SN) and specificity (SP) of regular magnetic resonance imaging (MRI) in the diagnosis and characterization of RCT and furthermore to link the results of MRI with the arthroscopy findings. The limitations and pitfalls if any with MRI patients presenting were also addressed. MATERIALS AND METHODS The study was a diagnostic evaluation study conducted at the Department of Radiodiagnosis, Muslim Educational Society (MES) Medical College, Perinthalmanna, India, among individuals with RCT between December 1, 2015, and May 31, 2017. Patients who were referred for MRI and then taken up for arthroscopy were included. The findings for each tendon of rotator cuff on MRI were contrasted with that of arthroscopy, and the percentage of agreement was calculated. Additional findings relevant to the study were also noted. SN, SP, positive predictive value (PPV), and negative predictive value (NPV) of MRI were determined by taking arthroscopic findings as the gold standard. RESULTS The study was comprised of 36 patients assessed using MRI and arthroscopy for RCT. The study participants ranged in age from 31 to 70 years, with a mean of 52.69±8.86 years. The majority of the patients (69.4%) were between the ages of 41 and 60 years. MRI had 100% SN and SP for full-thickness supraspinatus (SS) tear, 50% SN and 100% SP for partial-thickness SS tear, 100% SN and 80% SP for full-thickness infraspinatus (IS) tear, 75% SN and 80% SP for partial-thickness IS tear, and 95% SN and 86.6% SP for subscapularis (SC) tear. CONCLUSION The MRI RCT investigation had a high SN, SP, and PPV compared to arthroscopy. The most frequently involved tendon reported in the present study was SS (n=35; 97.22%) followed by IS (n=32; 88.88%) and SC (n=22; 61.11%). The teres minor tendon was least commonly affected (n=0). Moreover, 61.11% (n=22) of the patients had joint effusion, 41.66% (n=15) had subacromial-subdeltoid bursal effusion, and 27.77% (n=10) had subcoracoid effusion, suggesting that RCT include joint effusion or bursal fluid. Acromioclavicular (AC) joint hypertrophy was found in 53% (n=19) of the patients, and 90% (n=17) were over 45 years old, indicating an association between age, AC joint hypertrophy, and RCT. Therefore, MRI has a good SN and SP for detecting various RCT. Therefore, it could be used to investigate a suspected RCT and should be considered a near-reference standard to arthroscopy for RCT diagnosis.

Abstract
Background: Subacromial pain syndrome is a common musculoskeletal shoulder problem. The accuracy of clinical tests is low and techniques such as ultrasound and magnetic resonance imaging have been added to set up a diagnosis. Previous researchers have usually only examined the symptomatic shoulder. However, there might be similar findings in the asymptomatic shoulder. Objective:The aim of the present study was to investigate the prevalence of structural abnormalities of both shoulders in patients with clinically diagnosed unilateral subacromial pain syndrome using diagnostic ultrasound. Methods: Bilateral ultrasound examinations were performed in 115 consecutive patients, 54 men and 61 women. The patients were recruited from primary care centers in the area of Stockholm, Sweden. Results: Abnormal ultrasound findings were found in both shoulders and increased with age (p = .0004). Bursitis was the most common ultrasound finding and significantly more prevalent in the symptomatic shoulder compared to the asymptomatic shoulder (90%:74%; p = .0021), though 73% of the bursitis were bilateral. Supraspinatus is the most vulnerable tendon of the rotator cuff in both shoulders. In terms of partial-thickness tears and tendinosis, the tendon was affected more commonly in the symptomatic shoulder compared to the asymptomatic shoulder (30%:14%: 14%; p = .0026) and (24%:10%; p = .0054), respectively, but for calcification no significant difference between the shoulders was found (18%:12%; 0.1988). Conclusion: Ultrasound detected shoulder abnormalities were present in both symptomatic and asymptomatic shoulders. Bursitis and partial-thickness tears were more common in the affected shoulder when compared to the unaffected shoulder. Ultrasound as well as clinical examination findings and patient´s history should be taken into consideration when diagnosing patients with subacromial pain syndrome.

Supraspinatus tears: predictability of magnetic resonance imaging findings based on clinical examination. J Shoulder Elbow Surg 2021; 30:1834-1843. [PMID: 33675978 DOI: 10.1016/j.jse.2021.02.013] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/27/2020] [Revised: 02/04/2021] [Accepted: 02/08/2021] [Indexed: 02/01/2023]
Abstract
BACKGROUND The shoulder physical examination is frequently performed to diagnose rotator cuff tears in clinical practice; however, there is insufficient evidence on which physical tests are efficient for shoulder impingements in primary care settings. The purposes of this study were (1) to analyze the accuracy of 8 clinical tests to diagnose supraspinatus tendon lesions and investigate whether the combination of these tests can improve the diagnostic values; (2) to assess which are the best positivity criteria for shoulder maneuvers-pain and/or weakness; and (3) to investigate the ability of these tests to distinguish between partial- and full-thickness tears. METHODS A total of 733 consecutive patients were prospectively evaluated by 4 shoulder surgeons in this multicenter diagnostic study from May 2017 to December 2018, and 8 clinical tests (empty-can, full-can test, drop arm, painful arc, Neer sign, Hawkins test, Patte test, and resisted external rotation) were compared with magnetic resonance imaging performed by blinded radiologists. We assessed the sensitivity, specificity, accuracy, positive and negative predictive values, and diagnostic odds ratio (DOR) for all tests. RESULTS For overall supraspinatus tears, the empty-can test showed the highest sensitivity (0.81), the Patte test (positive for pain and weakness) and the drop-arm test showed the highest specificity (0.99 and 0.98, respectively), and the best combination was the Neer sign and the drop-arm test (DOR, 12.92). The positivity criteria for pain associated with weakness showed the highest performance, with DORs of 16.94 for the Patte test and 10.45 for the empty-can test. The Patte test and resisted external rotation, positive for pain and weakness, showed the highest ability to distinguish between full- and partial-thickness tears (DOR, 5.69 and 5.35, respectively). The shoulder maneuvers showed low negative predictive values; the highest value (0.58) was found with the empty-can test. CONCLUSIONS (1) The clinical tests demonstrated excellent diagnostic values; the empty-can test had the highest sensitivity, whereas the drop-arm test and the Patte test had the highest specificity; and the best combination for detecting supraspinatus tears was the Neer sign and the drop-arm test. On the other hand, the physical examination findings showed limited values to rule out tears. (2) The best positivity criterion for shoulder maneuvers was pain associated with weakness. (3) The Patte test and resisted external rotation showed the highest ability to distinguish between full- and partial-thickness tears.

Reliability of high-resolution ultrasound and magnetic resonance arthrography of the shoulder in patients with sports-related shoulder injuries. PLoS One 2019; 14:e0222783. [PMID: 31545834 PMCID: PMC6756526 DOI: 10.1371/journal.pone.0222783] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2019] [Accepted: 08/21/2019] [Indexed: 11/29/2022] Open
Abstract
Introduction The shoulder, a very complex joint, offers a wide range of pathologies. Intraarticular abnormalities and rotator cuff injuries are mainly assessed and diagnosed by magnetic resonance arthrography (MRA). In contrast to this well-established gold standard, high-resolution ultrasound (US) offers an additional easy and excellent modality to assess the shoulder joint. Therefore, the purpose of this study was to evaluate in which anatomic structures and pathologies comparable results of US and MRA could be achieved. Materials and methods In this IRB-approved prospective study 67 patients with clinically suspected labral lesions, rotator cuff rupture, or injury of the long head of the biceps (LHB) tendon were enrolled. Each participant was examined with high resolution US, and directly followed by MRA at 3 Tesla with a standard sequence protocol. To evaluate the agreement of the diagnostic performance between US and MRA a weighted kappa statistic was used. Results Both of the investigated modalities yielded a moderate to almost perfect agreement in assessing a wide range of shoulder joint pathologies. For the rotator cuff, consistency was found in 71.64% for the supraspinatus tendon, in 95.52% for the infraspinatus tendon, in 83.58% for the subscapularis tendon, and in 98.51% for the teres minor tendon. The diagnostic accuracy between both modalities was 80.60% for the LHB tendon, 77.61% for the posterior labroligamentous complex, 83.58% for the acromioclavicular joint, and 91.04% for the assessment of osseous irregularities and impaction fractures. Conclusions High resolution US is a reliable imaging modality for the rotator cuff, the LHB tendon, and the acromioclavicular joint, so for these structures we recommend a preference for US over MRA based on its diagnostic accuracy, comfortability, cost effectiveness, and availability. If the diagnosis remains elusive, for all other intraarticular structures we recommend MRA for further diagnostic assessment.

Abstract
PURPOSE Previous studies reported sonography was inferior to MRI to predict hamstring tendon graft diameter for ACL reconstruction. This study aimed to investigate the correlation between intraoperative hamstring tendon graft diameter and its preoperative measurement using different sonographic scanning protocol from previous studies. METHODS Two cadaveric knees were utilized for validation. Sonographically guided gracilis tendon (G) and semitendinosus tendon (ST) injections were performed at myotendinous junction of sartorius using colored latex and then dissection was performed. In the clinical studies, 28 patients underwent primary ACL reconstruction were enrolled. Cross-sectional area (CSA) of G and ST were measured at myotendinous junction of Sartorius. The diameter of doubled G (2G), doubled ST (2ST) and quadrupled ST + G (4STG) were intraoperatively measured using graft sizing devices with 0.5-mm increments. RESULTS Cadaveric dissection showed the presence of latex on the surface of G and ST at myotendinous junction of Sartorius in all specimens. In the clinical studies, CSA of G, ST, and ST + G significantly correlated with diameter of 2G (r = 0.464, p = 0.039), 2ST (r = 0.712, p < 0.001), and 4STG (r = 0.792, p < 0.001), respectively. As a result of the simple linear regression analysis, 4STG diameter could be predicted by the following formula: 4.345 + 0.210 × CSA. The differences between calculated diameter by this formula and intraoperative 4STG diameter were within ± 0.5 mm in 89.3% (25/28) of subjects. CONCLUSIONS The diameter of 2ST and 4STG can be reliably predicted based on sonographic CSA measurement preoperatively. Sonography is a cost-effective alternate to repeat MRI to predict hamstring graft diameter preoperatively. LEVEL OF EVIDENCE Diagnostic study; Level II.

Abstract
BACKGROUND This study was designed to define the accuracy of shoulder ultrasonography for diagnosing supraspinatus tendon tears. This examination is routinely used by orthopedists and may do away with the need for other examinations for diagnosing these tendon injuries. The aim of this study was to evaluate the sensitivity and specificity of shoulder ultrasonography for diagnosing supraspinatus tendon injuries, using magnetic resonance imaging as the reference. DESIGN AND SETTING Prospective accuracy study at a single center: the Shoulder and Elbow Surgery Clinic of the Department of Orthopedics and Traumatology. METHODS Shoulder ultrasonography was performed on 80 patients of both genders, over 18 years of age, with complaints of shoulder pain and clinically suspected supraspinatus tendon lesions. Jobe's test and a full can test were performed. In addition, they underwent magnetic resonance imaging in a 3.0-tesla machine, as the reference standard. The examinations were performed and interpreted by radiologists. RESULTS Ultrasonography showed sensitivity of 36.3% and specificity of 91.7% for supraspinatus tears overall: sensitivity of 25.8% and specificity of 91.8% for partial tears and sensitivity of 46.2% and specificity of 100% for full-thickness tears. Ultrasonography showed high accuracy for diagnosing full-thickness tears: 91.3%. The p-values were 0.003 for tears overall, 0.031 for partial tears and < 0.001 for full-thickness tears. CONCLUSIONS Ultrasonography showed low sensitivity for detecting supraspinatus tears, but high specificity for both partial and full-thickness tears.
