Almeida GG, Graf N, Wildermuth S, Fischer T, Waelti S, Jacxsens M, Leschka S, Dietrich TJ. Diagnostic performance of long head of biceps tendon tears on MRI: systematic review and meta-analysis. Eur Radiol 2024; 34:4309-4320. [PMID: 38148406 DOI: 10.1007/s00330-023-10521-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2023] [Revised: 11/07/2023] [Accepted: 11/21/2023] [Indexed: 12/28/2023]
Abstract
OBJECTIVES The purpose of this meta-analysis was to determine the diagnostic performance of conventional MRI and MR arthrography for tendinosis, and partial and complete tears of the long head of the biceps tendon (LHBT) using arthroscopy as the reference standard. MATERIALS AND METHODS A systematic review was performed using predefined data fields in PubMed, and all articles published from January 2000 up to April 2022 were retrospectively pooled and reviewed. Six MRI studies on complete tear (n = 555) and ten studies on partial tear/tendinosis (n = 2487) were included in the analysis. Two of the included studies in each group investigated the use of MR arthrography. The data sets were analyzed using a univariate approach with the DerSimonian and Laird random effects model and the proportional hazards model. RESULTS MRI shows high specificities in diagnosing complete tears of the LHBT ranging from 93.0 to 99.0%. Diagnostic sensitivity was more heterogeneous ranging from 55.9 to 90.0%. The overall negative likelihood ratio was 0.29 (95% CI: 0.17-0.50) and the overall positive likelihood ratio was 37.3 (95% CI: 11.9-117.4). The mean sensitivity in diagnosing partial tear/tendinosis of the LHBT was 67.8% (95% CI: 54.3-78.9%) and the specificity was 75.9% (95% CI: 63.6-85.0%), resulting in a balanced accuracy of 71.9%. The overall negative likelihood ratio was 0.44 (95% CI: 0.32-0.59) and the overall positive likelihood ratio was 2.64 (95% CI: 1.91-3.65). CONCLUSION MRI is highly specific for the diagnosis of complete tears of the LHBT, whereas diagnostic sensitivity was more heterogeneous. The diagnosis of partial tears and/or tendinosis of the LHBT remains challenging on MRI, which may warrant complementary clinical examination or other imaging modalities to increase diagnostic confidence in equivocal cases. CLINICAL RELEVANCE STATEMENT Conventional MRI and MR arthrography have high diagnostic performance for complete tendon tear when compared to arthroscopy. The diagnosis of tendinosis/partial tears remains challenging and may require comparison with clinical tests and other imaging modalities. KEY POINTS •There is no clear consensus regarding the primary imaging modality for the evaluation of LHBT disorders. •Conventional MRI and MR arthrography are highly specific in diagnosing complete tears of the LHBT. •Diagnosis of partial tears/tendinosis of the LHBT on conventional MRI and MR arthrography remains a diagnostic challenge.

Abstract
BACKGROUND There is limited data in the literature regarding the role of nonarthrographic MRI for detecting biceps pulley (BP) lesions. PURPOSE To assess the accuracy of nonarthrographic MRI for detecting BP lesions, and to evaluate the diagnostic value of various MRI signs (superior glenohumeral ligament discontinuity/nonvisibility, long head of biceps (LHB) displacement sign or subluxation/dislocation, LHB tendinopathy, and supraspinatus and subscapularis tendon lesions) in detecting such lesions. STUDY TYPE Retrospective. POPULATION 84 patients (32 in BP-lesion group and 52 in BP-intact group-as confirmed by arthroscopy). FIELD STRENGTH/SEQUENCE 1.5-T, T1-weighted turbo spin echo (TSE), T2-weighted TSE, and proton density-weighted TSE spectral attenuated inversion recovery (SPAIR) sequences. ASSESSMENT Three radiologists independently reviewed all MRI data for the presence of BP lesions and various MRI signs. The MRI signs and final MRI diagnoses were tested for accuracy regarding detecting BP lesions using arthroscopy results as the reference standard. Furthermore, the inter-reader agreement (IRA) between radiologists was determined. STATISTICAL TESTS Student's t-tests, Chi-squared, and Fisher's exact tests, and 4-fold table test were used. The IRA was calculated using Kappa statistics. A P-value <0.05 was considered statistically significant. RESULTS The sensitivity, specificity, and accuracy of nonarthrographic MRI for detecting BP lesions were 65.6%-78.1%, 90.4%-92.3%, and 81%-86.9%, respectively. The highest accuracy was noticed for the LHB displacement sign (84.5%-86.9%), and the highest sensitivity was registered for the LHB tendinopathy sign (87.5%). Furthermore, the highest specificity was observed for the LHB displacement sign and LHB subluxation/dislocation sign (98.1%-100%). The IRA regarding final MRI diagnosis and MRI signs of BP lesions was good to very good (κ = 0.76-0.98). DATA CONCLUSION Nonarthrographic shoulder MRI may show good diagnostic accuracy for detecting BP lesions. The LHB displacement sign could serve as the most accurate and specific sign for diagnosis of BP lesions. LEVEL OF EVIDENCE 3 TECHNICAL EFFICACY: Stage 2.

Evaluation of Conventional MR Imaging of the Shoulder in the Diagnosis of Lesions of the Biceps Pulley. Acad Radiol 2024:S1076-6332(24)00062-X. [PMID: 38448326 DOI: 10.1016/j.acra.2024.01.040] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2023] [Revised: 01/20/2024] [Accepted: 01/29/2024] [Indexed: 03/08/2024]
Abstract
RATIONALE AND OBJECTIVES To determine the diagnostic accuracy and reproducibility of conventional MR imaging (MRI) of the shoulder in evaluating biceps pulley lesions using arthroscopy as the standard of reference. METHODS In a retrospective study, MR examinations of 68 patients with arthroscopically proven torn or intact biceps pulley were assessed for the presence of pulley lesions by three radiologists. The following criteria were evaluated: displacement of the long head of the biceps tendon (LHBT) relative to the subscapularis tendon (displacement sign), subluxation/dislocation of the LHBT, the integrity of the superior glenohumeral ligament (SGHL) and the coracohumeral ligament (CHL), lesions of the supraspinatus (SSP) and subscapularis (SSC) tendons adjacent to the rotator interval, presence of biceps tendinopathy and subacromial bursitis. RESULTS There were 42 patients with pulley lesions in the study group. Conventional MR imaging showed an overall sensitivity of 95.2%, 88.1% and 92.9%, a specificity of 61.5%, 73.1%, and 80.8% and an accuracy of 82.4%, 82.4% and 88.2% in the diagnosis of pulley lesions. Interobserver agreement was substantial (multirater k = 0.75). Biceps tendinopathy (97.6%, 95.2%, 97.6%), defects of the SGHL (86.3%, 81.0%, 88.1%) and the displacement sign (88.1%, 81.0%, 85.7%) were the most sensitive diagnostic criteria. Subluxation/dislocation of the LHBT was insensitive (78.6%, 42.9%, 33.3%), but specific (69.2%, 100,0%, 96.2%). CONCLUSION In the diagnosis of pulley lesions, conventional MR imaging is reproducible and shows high sensitivity and accuracy but moderate specificity.

[PMID: 37566148 PMCID: PMC10730654 DOI: 10.1007/s00256-023-04420-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/26/2023] [Revised: 07/23/2023] [Accepted: 07/29/2023] [Indexed: 08/12/2023]
Abstract
OBJECTIVE Direct magnetic resonance arthrography (dMRA) is often considered the most accurate imaging modality for the evaluation of intra-articular structures, but utilization and performance vary widely without consensus. The purpose of this white paper is to develop consensus recommendations on behalf of the Society of Skeletal Radiology (SSR) based on published literature and expert opinion. MATERIALS AND METHODS The Standards and Guidelines Committee of the SSR identified guidelines for utilization and performance of dMRA as an important topic for study and invited all SSR members with expertise and interest to volunteer for the white paper panel. This panel was tasked with determining an outline, reviewing the relevant literature, preparing a written document summarizing the issues and controversies, and providing recommendations. RESULTS Twelve SSR members with expertise in dMRA formed the ad hoc white paper authorship committee. The published literature on dMRA was reviewed and summarized, focusing on clinical indications, technical considerations, safety, imaging protocols, complications, controversies, and gaps in knowledge. Recommendations for the utilization and performance of dMRA in the shoulder, elbow, wrist, hip, knee, and ankle/foot regions were developed in group consensus. CONCLUSION Although direct MR arthrography has been previously used for a wide variety of clinical indications, the authorship panel recommends more selective application of this minimally invasive procedure. At present, direct MR arthrography remains an important procedure in the armamentarium of the musculoskeletal radiologist and is especially valuable when conventional MRI is indeterminant or results are discrepant with clinical evaluation.

Abstract
BACKGROUND Injuries to the biceps reflection pulley lead to instability of the long head of the biceps tendon (LHBT). However, conventional magnetic resonance (MR) imaging (MRI) has low diagnostic accuracy for LHBT and pulley lesions. Here, we investigated the usefulness of novel biceps-radial MRI for evaluating LHBT and pulley lesions. METHODS Biceps-radial MR images of 84 patients (84 shoulders) were prospectively analyzed. The biceps-radial MRI protocol includes sequences acquired in radial planes perpendicular to the LHBT in the shoulder joint. All patients underwent shoulder arthroscopy, and the intraoperative LHBT and pulley lesion findings were compared to the preoperative evaluations. The diagnostic accuracies of the biceps-radial MR images and conventional MR images were determined. RESULTS A normal LHBT was observed in 30 (31.6%) patients, partial tears in 43 (52.6%), and complete tears in 11 (15.8%). Normal LHBT stability was present in 54 (61.4%) patients, subluxation in 24 (31.6%), and dislocation in 6 (7.0%). The biceps-radial MR (kappa coefficient: 0.94) and conventional MR (kappa coefficient: 0.68) images accurately identified LHBT tears. The biceps-radial MR images excellently agreed with the arthroscopic findings (kappa coefficient: 0.91), whereas the conventional MR images poorly agreed (kappa coefficient: 0.17) regarding LHBT instability. A normal medial wall of the pulley was observed in 26 (31.0%) patients, partial tears in 30 (35.7%), and complete tears in 28 (33.3%). A normal lateral wall of the pulley was observed in 30 (35.7%) patients, partial tears in 21 (25.0%), and complete tears in 33 (39.3%). The biceps-radial MR images excellently agreed with the arthroscopic findings (kappa coefficient: 0.89), whereas the conventional MR images moderately agreed (kappa coefficient: 0.50) regarding medial pulley lesions. The biceps-radial MR images excellently agreed with the arthroscopic findings (kappa coefficient: 0.95) and the conventional MR images moderately agreed (kappa coefficient: 0.56) regarding lateral pulley lesions. CONCLUSION Biceps-radial MRI allows for tracking of the LHBT and pulley from the supraglenoid tuberosity to the bicipital groove in the glenohumeral joint and accurate evaluations of LHBT and pulley lesions.

Abstract
Chronic shoulder pain is an extremely common presenting complaint. Potential pain generators include the rotator cuff tendons, biceps tendon, labrum, glenohumeral articular cartilage, acromioclavicular joint, bones, suprascapular and axillary nerves, and the joint capsule/synovium. Radiographs are typically the initial imaging study obtained in patients with chronic shoulder pain. Further imaging may often be required, with modality chosen based on patient symptoms and physical examination findings, which may lead the clinician to suspect a specific pain generator. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision process support the systematic analysis of the medical literature from peer reviewed journals. Established methodology principles such as Grading of Recommendations Assessment, Development, and Evaluation or GRADE are adapted to evaluate the evidence. The RAND/UCLA Appropriateness Method User Manual provides the methodology to determine the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where peer reviewed literature is lacking or equivocal, experts may be the primary evidentiary source available to formulate a recommendation.

Abstract
BACKGROUND This review aimed to explore the available literature to update our understanding of the long head of biceps (LHB) at the shoulder. Synthesise our findings to identify emergent themes and knowledge gaps to inform future research and management directions. METHODS PubMed, Embase, Cinahl, SportDiscus, CENTRAL, and Web of Science were searched from inception to 31st December 2021. Articles were included if they referenced adult participants > 18 years of age and were written in English. RESULTS 214 articles were included in the final analysis, and results were categorised into six emergent themes: (1) Anatomy - Normal anatomical variation of the biceps from aberrant origins, third and fourth accessory heads, and an absence of the LHB tendon (LHBT) are not necessarily benign, with shoulder pain and instability a commonly reported theme. (2) Function - Bicep's role in glenohumeral elevation and stability in healthy shoulders is minimal. In contrast, LHB has a more significant role in shoulder stability and humeral head depression in subjects with rotator cuff failure or an absent LHBT. (3) Pathology - There is an association between LHB tendinopathy, rotator cuff disease, LHBT instability and occult rotator cuff tears. Early recruitment and hyperactivity of the LHB in subjects with symptomatic rotator cuff tears and instability suggest a potential compensatory role. (4) Assessment - The limited diagnostic utility of special orthopaedic tests in assessing LHBT pathology was a consistent theme. The utility of magnetic resonance imaging and ultrasound to identify full-thickness tendon tears and instability of the LHBT was moderate to high. However, the utility of clinical tests and imaging may be underestimated due to arthroscopy's limitations in fully visualising the proximal LHBT. (5) Non-Surgical Management - Ultrasound-guided injections into the biceps sheath show greater accuracy and patient outcomes than blinded injections; however, the entry of injectate into the intraarticular glenohumeral joint may have unwanted complications. (6) Surgical management - For the surgical management of biceps pathology with or without rotator cuff pathology, both biceps tenodesis and tenotomy report similar improvements in pain without any significant adverse effect on strength or function. Tenodesis favoured higher overall constant scores and a lower incidence of Popeye deformity and cramping arm pain, with tenotomy trending to be more cost and time effective. For patients with a healthy LHBT, rotator cuff repair with adjunctive tenodesis or tenotomy fails to provide additional clinical improvements compared to rotator cuff repair in isolation. CONCLUSIONS The scoping review highlights the variability of biceps anatomy, which is not necessarily benign and suggests a minimal role of the LHB in shoulder elevation and stability in healthy individuals. In contrast, individuals with rotator cuff tears experience proximal humeral migration and demonstrate hyperactivity of the LHB, suggesting a potential compensation role. The observed prevalence of LHBT pathology with rotator cuff tears is well established; however, the cause-and-effect relationship between LHBT pathology and rotator cuff disease is undetermined. The diagnostic utility of clinical tests and imaging to exclude LHBT pathology may be understated due to the limitations of arthroscopy to visualise the proximal LHBT fully. Rehabilitation programs for the LHB are understudied. Similar post-surgical clinical outcomes are observed for tenodesis and tenotomy for biceps and rotator cuff-related shoulder pain. Subjects undergoing biceps tenodesis are less likely to have cramping arm pain and a Popeye deformity than patients undergoing biceps tenotomy. The significance of routine surgical removal of the LHBT and sequelae on rotator cuff tear progression to failure and long-term shoulder function is unknown, and further research is required.

MATERIALS AND METHODS A search was performed on PubMed, Embase®, and Cochrane. Studies that compared the diagnostic accuracy of 3D imaging modalities versus arthroscopy for the assessment of LHBT pathologies were included. Studies assessing superior labral anterior posterior (SLAP) lesions were excluded. RESULTS Fifteen studies were included; nine were eligible for meta-analysis. Six studies on instability indicated a sensitivity of 0.68 (CI 0.46-0.84) and specificity of 0.76 (CI 0.68-0.82). Four studies on full-thickness tears indicated a sensitivity of 0.56 (CI 0.28-0.81) and specificity of 0.97 (CI 0.93-0.99). Four studies on partial-thickness tears indicated a sensitivity of 0.52 (CI 0.20-0.82) and specificity of 0.64 (CI 0.25-0.91). Two studies on any tear indicated a sensitivity of 0.58 (CI 0.28-0.83) and specificity of 0.99 (CI 0.93-1.00). Only one study on other pathologies indicated a sensitivity of 0.61 and specificity of 0.84. CONCLUSION To diagnose LHBT pathologies, 3D imaging modalities overall have low-to-moderate sensitivity, but high-to-excellent specificity. The consistency in reported sensitivity is generally poor, while the consistency and reported specificity is good for the detection of instability, full-thickness tears and any tear, but poor for the detection of partial-thickness tears. 3D imaging may be adequate to rule out LHBT pathologies, but are not sufficiently reliable to confirm the presence of such pathologies.

Arthroscopic diagnosis of long head of biceps tendon instability in refractory anterior shoulder pain: A comparison study between pulley tear and non-tear lesions. Biomed J 2022; 46:163-169. [PMID: 35065282 PMCID: PMC10104962 DOI: 10.1016/j.bj.2022.01.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2020] [Revised: 12/23/2021] [Accepted: 01/10/2022] [Indexed: 11/02/2022] Open
Abstract
BACKGROUND Long head of the biceps tendon (LHBT) instability and biceps reflection pulley (BRP) lesions are common cause of refractory anterior shoulder pain. We described a technique using dynamic arthroscopy to determine associated intraarticular pathologies. METHODS Patients with refractory anterior shoulder pain and arthroscopically-diagnosed LHBT instability were enrolled. LHBT instability and the integrity of BRP and concomitant intra-articular lesions were investigated by ramp test. Demographics and arthroscopic findings were compared between patients with and without BRP tear. RESULTS Forty patients were enrolled. BRP tear was noted in 25 patients (group A) and superior glenohumeral ligament (SGHL) insufficiency through ramp test in 15 patients (group B). Concomitant intraarticular pathologies were noted in 27 patients, including 19 in group A (76%) and eight in group B (53%), without significant group-wise difference (p = 0.138). The incidence of articular-side subscapularis tear was significantly higher in group A (p = 0.021), and those of the other intraarticular pathologies were similar between groups A and B. Fraying at the articular side of the subscapularis and supraspinatus tendons was frequent in group B, without difference of incidence as compared to group A (p = 0.5 and p = 0.084, respectively). CONCLUSIONS LHBT instability was a common disorder in patients with refractory shoulder pain. In those patients, dynamic assessment of BRP lesions and SGHL insufficiency and meticulous survey of associated intra-articular pathologies, including subscapularis tear are necessary for making accurate diagnosis and treatment decision.

Abstract
BACKGROUND Data regarding controlled aliasing in parallel imaging results in higher acceleration (CAIPIRINHA) T2-weighted sampling perfection with application optimized contrast evolution (SPACE) with fourfold acceleration factor for assessing long head of biceps tendon (LHBT) disorder is lacking. PURPOSE To investigate the feasibility of 3D CAIPIRINHA SPACE with fourfold acceleration in assessing LHBT disorder. MATERIAL AND METHODS A total of 42 consecutive patients underwent shoulder magnetic resonance (MR) examinations including CAIPIRINHA SPACE with fourfold acceleration, and non-CAIPIRINHA SPACE with twofold acceleration, and 2D fast spin echo (FSE). A subjective score of depiction of LHBT was given to 3D sequence according to a 4-point scale (0-3, "poor" to "excellent"). The Wilcoxon signed rank test was used to compare depiction scores between 3D sequences. Three statuses of LHBT were defined in the study: normal, tendonitis, and tear. McNemar's test was used compare diagnostic accuracy. RESULTS LHBT was better depicted with CAIPIRINHA SPACE versus non-CAIPIRINHA SPACE (2.1 ± 0.4 vs. 1.5 ± 0.4; P < 0.001). Inter-modality agreement between CAIPIRINHA SPACE and 2D FSE was almost perfect (kappa = 0.884 ± 0.064). The sensitivity and specificity in detecting LHBT disorder were 95% (20/21) and 95% (20/21), respectively, for CAIPIRINHA SPACE, and 71% (15/21) and 76% (16/21), respectively, for non-CAIPIRINHA SPACE (P = 0.039). CONCLUSION Fourfold acceleration CAIPIRINHA is feasible in reducing the acquisition time of SPACE MR in the shoulder. 3D CAIPIRINHA SPACE with fourfold acceleration is highly accurate in detecting LHBT disorder.

High Incidence of Anterior Shoulder Pain in Young Athletes Undergoing Arthroscopic Posterior Labral Repair for Posterior Shoulder Instability. Arthrosc Sports Med Rehabil 2021; 3:e1441-e1447. [PMID: 34712982 PMCID: PMC8527323 DOI: 10.1016/j.asmr.2021.06.012] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2020] [Accepted: 06/25/2021] [Indexed: 11/24/2022] Open
Abstract
Purpose The purposes of this study were to determine the incidence of anterior shoulder pain in young athletes undergoing arthroscopic posterior labral repair for symptomatic unidirectional posterior shoulder instability and in patients with preoperative anterior shoulder pain treated without biceps tenodesis at the time of arthroscopic posterior labral repair who underwent a revision biceps tenodesis procedure at short-term follow up. Methods A retrospective review was performed at a single institution over a 24-month period. The study included young patients who underwent an arthroscopic posterior labral repair for symptomatic unidirectional posterior shoulder instability. The electronic medical record, magnetic resonance arthrograms, and arthroscopic images were reviewed to exclude patients with posterior labral tears with anterior labral tear or SLAP (superior labrum anterior-to-posterior) tear extension on advanced imaging and arthroscopic examination. Data collected included the presence of preoperative tenderness to palpation of the biceps tendon in the groove, the results of a preoperative Speed test, postoperative Subjective Shoulder Value, the presence of postoperative anterior shoulder pain, and the need for a secondary biceps tenodesis. Results We identified 65 patients who underwent arthroscopic labral repair for posterior shoulder instability. From this cohort, 26 patients with symptomatic unidirectional posterior shoulder instability underwent an arthroscopic posterior labral repair. The incidence of preoperative anterior shoulder pain with Zone 2 biceps groove tenderness and a positive Speed test was identified in 20 of 26 patients (76.9%). Of 26 patients, 5 (19%) had concomitant biceps tenodesis. The median postoperative Subjective Shoulder Value was 80 (interquartile range, 60-90) at median follow-up of 2.1 years. Of the 20 patients with preoperative anterior shoulder pain, 8 of 20 (40%) reported persistent anterior pain. One patient (4.7%) underwent a secondary biceps tenodesis. Conclusions There is a high incidence of anterior shoulder pain and Zone 2 biceps groove tenderness in patients undergoing isolated arthroscopic posterior labral repair for unidirectional posterior shoulder instability. At short-term follow-up, few patients required a secondary biceps tenodesis procedure; however, 30% of patients had persistent anterior shoulder pain.

Abstract
OBJECTIVE The aim of this work was to evaluate the inter-observer agreement and diagnostic performance values of 7 MRI signs (3 known and 4 new) of long head biceps tendon instability. MATERIALS AND METHODS MRI of 86 patients were retrospectively evaluated. Inter-observer agreement and diagnostic performance of each diagnostic sign and of all combined signs (with the exception of detour sign) were tested for identification of biceps tendon instability, with arthroscopy as the reference standard. RESULTS Agreement between expert operators was moderate to good. Sensitivity, specificity, and sign accuracy showed a variation respectively of the following: humeral chondral print 72-80%, 62-68%, and 70-76%; subchondral bone edema 24-31%, 84-97%, and 50%; biceps tendon angle 60-71%, 97-100%, and 74-81%, biceps tendon-groove distance 31-47%, 90-100%, and 56-64%; long head biceps subluxation/dislocation on axial plane 49-53%, 97-100%, and 66-70%; displacement sign 74-80%, 74-100%, and 74-87%; detour sign 51-64%, 58-81%, and 62-64%; and all signs 98-100%, 32-61%, and 75-86%. CONCLUSION These diagnostic signs, both known and new, individually and/or in combination, provide a valid tool in the MRI diagnosis of long head biceps tendon instability.

Abstract
Introduction Medial dislocation of the long head of the biceps tendon (LHBT) is classically known as a pathognomonic finding for a subscapularis or at least a rotator cuff (RC) injury. However, this case report outlines a young active individual with symptomatic medial dislocation of the long head of the biceps with associated posterior instability, without a corresponding RC injury. Case Report An 18-year-old male complained of the left shoulder pain and crepitus after a shoulder injury while playing hockey a year prior. Magnetic resonance imaging demonstrated medial dislocation of the LHBT without subscapularis or supraspinatus tendon injury. The patient complained of instability in the shoulder and exam findings supported posterior instability of the glenohumeral joint. Arthroscopic debridement of the glenohumeral joint with arthroscopic posterior capsulorrhaphy and open biceps tenodesis was performed. The patient regained full and painless range of motion at 2-year follow-up. Conclusion Medial dislocation of the LHBT can occur without injury to the subscapularis tendon. Furthermore, a capsulorrhaphy with open biceps tenodesis and closure of the rotator interval may provide a successful outcome for this rare injury pattern.

Abstract
PURPOSE To evaluate the diagnostic accuracy between magnetic resonance arthrography (MRA) and arthroscopic examination for the assessment of pathologies of the long head of the biceps (LHB) prior to rotator cuff (RC) repair. The hypothesis was that MRA is suitable to identify biceps instabilities, due to improved visibility of the biceps pulley. METHODS Sixty-six patients aged 58.5 ± 17.6 (range, 46-71) scheduled to have RC repair between 2016 and 2017 were prospectively enrolled. MRA images of the LHB were interpreted by one radiologist and two surgeons, then compared to arthroscopic findings. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated by comparing MRA axial readings to arthroscopic assessment in the neutral position (static instability), MRA sagittal readings to arthroscopic assessment in external rotation (dynamic s instability), MRA coronal and axial readings to arthroscopic assessment in the neutral position (tendinopathy). RESULTS Among the three observers, the radiologist obtained the highest sensitivity and specificity for MRA, which were respectively: (1) for static instability, 62% (C.I. 35-85) and 77% (C.I. 63-88); (2) for dynamic instability, 50% (C.I. 29-71) and 62% (C.I. 46-77), and (3) for tendinopathy, 49% (C.I. 36-62) and 100% (C.I. 3-100). CONCLUSIONS MRA is not suitable for the diagnosis of LHB lesions prior to arthroscopic rotator cuff repair. LEVEL OF EVIDENCE Diagnostic study, Level I.

Abstract
OBJECTIVE To evaluate the diagnostic accuracy of magnetic resonance imaging (MRI) for detection of instability and tears of the proximal long head of biceps tendon (LHBT). To assess intraobserver and interobserver agreement. MATERIALS AND METHODS We performed a retrospective analysis of prospectively collected data of 100 consecutive shoulders who underwent non-contrast 1.5-T MRI prior to arthroscopic surgery due to rotator cuff injury. Images were independently analyzed by two musculoskeletal radiologists. LHBT was evaluated for presence of tearing (intact, longitudinal split, partial-thickness, or full-thickness) and position (normal, subluxated, and dislocated). Anterosuperior rotator cuff tears were also assessed. The reference standard was arthroscopic surgery. The ramp test was performed in order to evaluate LHBT stability. Diagnostic performance measures were determined and Kappa coefficients assessed agreement. RESULTS Concerning the detection of overall tears, sensitivity ranged from 71 to 73% and specificity was 73%. The specificity for full-thickness tears ranged from 75 to 96%. Overall displacement showed sensitivity ranging from 51 to 58% and specificity ranging from 70 to 86%. The specificity of overall displacement combined with anterosuperior rotator cuff tears ranged from 73 to 91%. Interobserver Kappa values were between 0.59 and 0.69. Intraobserver Kappa values were between 0.74 and 0.82. CONCLUSIONS MRI has moderate accuracy and good agreement for detection of LHBT tears and instability. There is a tendency for increased specificity for full-thickness tears and for instability in the coexistence of anterosuperior rotator cuff tears.

Abstract
Background: Asymptomatic, incidental extensor carpi ulnaris (ECU) tendon abnormalities are frequently noted on imaging studies of the wrist. The aim of this investigation was to determine if variations in gross tendon anatomy existed that could possibly account for these findings on MRI and ultrasound (US) imaging. Methods: The upper extremities of eleven (6 male and 5 female) formalin preserved cadavers were dissected and examined under loupe magnification with attention to the dorsal-ulnar wrist and hand and the ECU tendon. The tendons were inspected for anatomic variations, degenerative changes, and any other pathologies. The presence of intra-tendinous splits arising within the ECU tendon was noted and measured. The distances of the splits from the distal tendon insertion and the edge of the extensor retinaculum were recorded. Statistical correlations between age and the tendon splits were considered using R-squared to assess a linear regression. Results: 17 ECU tendons were dissected and examined, and 5 ECU tendons were excluded due to poor preservation of that upper extremity; all five were right sided upper extremities. Eleven of the 17 specimens demonstrated at least one split in the distal tendon: Seven had 1 split, 1 had 2 splits, and 3 had 3 splits. The mean length of the tendon split was 3.52 cm. The mean distance of the distal edge of the split to the tendon insertion site was 2.4 cm. A linear regression was calculated and showed no correlation between age and number of tendon splits. Conclusions: 64% of specimens showed a longitudinal split in the distal ECU tendon. The location of these frequent splits corresponds to imaging abnormalities on MRI and US in prior studies.
