Diagnostic accuracy of preoperative magnetic resonance imaging for detecting subscapularis tendon tears: a diagnostic test study

Abstract: Although the biomechanical importance of the subscapularis tendon has been recognized in biomechanical 1 and clinical studies, 2 it has long received little attention in the medical literature, 3 and has been called the "forgotten tendon". 4 Only 1% of rotator cuff tears affect only the subscapularis, 5,6 but more than half of all patients with supraspinatus tears present an associated tear of this tendon. 7,8 The accuracy of magnetic resonance imaging (MRI) is usually lower for detection of subscapularis tear… Show more

“…Clinicians often evaluated the severity of SSC tendon injuries on MRI according to changes in tendon morphology and signal, but there were still some limitations [ 7 , 12 , 23 ]. A reliable risk estimation tool is helpful for the screening and early identification of patients with SSC tendon tears.…”

“…MR-images are routinely used and read separately by the ordering orthopaedic surgeons and radiologists, the latter specialty generating an MRI report [ 3 , 4 ]. An additional cause for increased MRI utilization can be the patient generated request or the result of medical legal considerations, often encountered in the Canadian tort system.…”

“…They receive the referral often in order to prevent a legal action and for the sake of enhancing the patient-doctor relationship [ 5 , 6 ]. Despite increase in MR-imaging quality, signals detected may represent false positive pathologies particularly in cases of rotator cuff tears [ 4 , 7 , 8 ]. Changes in signal sensitivity, pixels and the width of the generated slice can lead to a discrepancy between pathologic and non-pathologic images [ 9 , 10 ].…”

“…Although the diagnostic performance of magnetic resonance imaging (MRI) in supraspinatus and infraspinatus tendon tears is excellent, it has been challenging to find MRI as an effective diagnostic tool for SSC tendon tears ( 4 6 ). Especially, the smaller and partial-thickness tears could directly decrease the diagnostic accuracy of MRI ( 7 9 ). Considering the SSC tendon tear usually begins at the upper part of the tendon insertion, most of which occurred in the superior one-third of the tendon insertion ( 10 ), the presence of a partial volume effect will also make it difficult to visualize the lesions in the anterosuperior region ( 11 ).…”
