“…Although conventional magnetic resonance imaging has been reported to identify labral pathology with sensitivities of 76% to 93% and specificities of 68% to 87%, magnetic resonance arthrography has been reported to have improved diagnostic results, with sensitivities ranging from 88% to 92% and specificities ranging from 92% to 93%. [24][25][26][27][28][29] When glenohumeral osseous deficiency is suspected, computed tomography (CT) scans are particularly helpful in determining the extent of glenoid and humeral bone loss in cases of instability. Compared with radiography, conventional CT, and magnetic resonance imaging, 3-dimensional CT has been shown to be the most reliable imaging modality for the quantification of glenoid and humeral bone loss and can be combined with arthrography to allow for simultaneous assessment of soft-tissue structures in addition to the osseous anatomy.…”

Anterior glenohumeral instability is a common clinical entity, particularly among young athletic patient populations. Nonoperative management and arthroscopic treatment of glenohumeral instability have been associated with high rates of recurrence, particularly in the setting of glenohumeral osseous defects. Coracoid transfer, particularly the Latarjet procedure, has become the treatment of choice for recurrent anterior glenohumeral instability in the setting of osseous deficiencies greater than 20% to 30% of the glenoid surface area and may also be considered for the primary treatment of recurrent instability in the high-risk contact athlete, even in the setting of limited osseous deficiency. The following Technical Note provides a diagnostic approach for suspected glenohumeral instability, as well as a detailed description of the congruent-arc Latarjet procedure, performed with a deltoid split, with its postoperative management.

“…MRI may also be augmented with the use of contrast, as in magnetic resonance arthrogram (MRA). Studies have reported good sensitivities and specificities with these two modalities (6)(7)(8). Some studies have gone further to show the superiority of MRA over MRI in the diagnosis of labral tears (5,8,9).…”

Is clinical evaluation alone sufficient for the diagnosis of a Bankart lesion without the use of magnetic resonance imaging?

Background: Imaging modalities such as magnetic resonance arthrogram (MRA) offer great utility in diagnosing Bankart lesions but they are associated with a high degree of intra and interobserver variability. This study aims to evaluate the diagnostic accuracy of clinical evaluation and imaging modalities in Bankart lesions such as magnetic resonance imaging (MRI) and MRA of the shoulder. Conclusions: In our study, we report that clinical evaluation with focused history-taking and anterior apprehension, load and shift clinical examination can diagnose anterior shoulder instability as reliably as MR imaging. For patients with equivocal clinical findings, MR imaging can aid in the diagnosis.

purpose. To compare preoperative non-contrast magnetic resonance imaging (MRI) with arthroscopy findings in diagnosing labral and rotator cuff tears. Methods. 86 men and 60 women aged 21 to 70 (mean, 52) years underwent non-contrast MRI before arthroscopic operations on the glenohumeral joint. Slices were made in a transvese, parasagittal, and paracoronar orientation. The sequences used were T2-and proton-weighted for paracoronar imaging, T1-and T2-weighted for transverse and parasagittal imaging, and T2-weigthed sequences with fat suppression and short tau inversion recovery sequences. MRI was evaluated with the surgeon to eliminate interobserver bias. Arthroscopic surgery was performed by a single surgeon. If a labral or rotator cuff tear was found, surgery was performed using corkscrew anchors. results. For full thickness rotator cuff tears, MRI and arthroscopy detected them in 76 and 82 patients, respectively. One such tear found by MRI could Non-contrast magnetic resonance imaging for diagnosing shoulder injuries Heino ArnoldOrthopaedisch -Unfallchirurgische Praxisklinik, Orrthopaedisches Zentrum Fichtelgebirge, Rehau, Germany Address correspondence and reprint requests to: Dr Heino Arnold, Orthopaedisch -Unfallchirurgische Praxisklinik, Orrthopaedisches Zentrum Fichtelgebirge, Bahnhofstrasse 10, 95111 Rehau, Germany.

The sensitivity and specificity of MRI in diagnosing full thickness rotator cuff tears were 0.90 and 0.91, respectively. For labral tears, MRI and arthroscopy detected them in 16 and 31 patients, respectively. One anterior labral tear detected by MRI could not be verified by arthroscopy. All 16 labral tears detected by MRI were Bankart type-I tears (of the anterior glenoid) except for one superior labral tear from anterior to posterior (SLAP tear). All 13 SLAP tears (10 type 2 and 3 type 3) except for one could be found by arthroscopy only. The sensitivity and specificity of MRI in diagnosing labral tears were 0.52 and 0.89, respectively. conclusion. Non-contrast MRI is reliable only for diagnosing full thickness rotator cuff tears and anterior labral tears. Direct or indirect contrast enhancement is recommended for more differentiation. Special scan orientation is necessary for SLAP tears. Journal of Orthopaedic Surgery

Labral-ligamentous complex of the shoulder: evaluation with MR arthrography.

Abstract: MR arthrography accurately shows the relationship of labral lesions to the origins of the glenohumeral ligaments and helps in distinction between stable and unstable lesions.
