“…Scar tissue formation, thickening of the joint capsule, and shortening of the axillary recess are often evident in patients who have undergone capsular shift or LACS/ETACS (Fig. 2d) [7,9,10,23]. Following open Bankart repair, the reattached subscapularis tendon might appear swollen and can demonstrate increased signal intensity, particularly on T1-and proton-density-weighted MR images (Fig.…”

“…Retears of the labro-ligamentous complex can have a variable appearance on MR arthrography ranging from partial or complete separation of the labrum and/or IGHL from the glenoid (Fig. 3) to capsular stripping with medial and inferior displacement of the labroligamentous complex on the scapular neck [4,5,7,23]. The ABER position might be valuable to demonstrate nondisplaced retears or lesions which are otherwise obscured by scar tissue.…”

“…The ABER position might be valuable to demonstrate nondisplaced retears or lesions which are otherwise obscured by scar tissue. Another advantage of MR arthrography (and CT arthrography) is their potential to estimate postoperative capsular volume [23].

Multimodality imaging of the postoperative shoulder

Multimodality imaging of the postoperative shoulder includes radiography, magnetic resonance (MR) imaging, MR arthrography, computed tomography (CT), CT arthrography, and ultrasound. Target-oriented evaluation of the postoperative shoulder necessitates familiarity with surgical techniques, their typical complications and sources of failure, knowledge of normal and abnormal postoperative findings, awareness of the advantages and weaknesses with the different radiologic techniques, and clinical information on current symptoms and function. This article reviews the most commonly used surgical procedures for treatment of anterior glenohumeral instability, lesions of the labral-bicipital complex, subacromial impingement, and rotator cuff lesions and highlights the significance of imaging findings with a view to detection of recurrent lesions and postoperative complications in a multimodality approach.

When pain or disability occurs after rotator cuff surgery, post-operative imaging is frequently performed. Post-operative complications and expected post-operative imaging findings in the shoulder are presented, with a focus on MRI, MR arthrography (MRA) and CT arthrography. MR and CT techniques are available to reduce image degradation secondary to surgical distortions of native anatomy and implant-related artefacts and to define complications after rotator cuff surgery. A useful approach to image the shoulder after surgery is the standard radiography, followed by MRI/MRA for patients with low "metal presence" and CT for patients who have a higher metal presence. However, for the assessment of patients who have undergone surgery for rotator cuff injuries, imaging findings should always be correlated with the clinical presentation because post-operative imaging abnormalities do not necessarily correlate with symptoms.The complexity of the anatomy and function of the rotator cuff makes the rotator cuff tendons vulnerable to considerable morbidity, often necessitating surgical intervention. Optimal management of rotator cuff abnormalities depends on a variety of factors, such as the presence and severity of an impingement, the degree of tendon damage and individual functional demands.1 The goals of rotator cuff surgery are to reduce pain, while simultaneously improving the function. The latter is accomplished by two main types of surgical procedures: (1) subacromial decompression surgery alone, typically with an acromioplasty and/or Mumford procedure (distal clavicular resection); and (2) repair of the rotator cuff tear (open or arthroscopic), which is almost always accompanied by a subacromial decompression.Post-operative imaging is performed when pain or disability occurs after a surgical procedure. Often, however, postoperative imaging is degraded by surgical distortions of the native anatomy and metallic artefacts related to implants. Nevertheless, it is imperative that clinicians have an accurate anatomical delineation of the operative site. It is also important for the radiologist to accurately diagnose complications that might occur after rotator cuff surgery to guide optimal treatment. Mansat et al 2 examined 40 articles reporting the results of open rotator cuff repairs and determined that the overall mean complication rate was 10.5%.The article addresses complications that occur after rotator cuff surgery and expected post-operative imaging findings, with a focus on MRI, MR arthrography (MRA) and CT arthrography (CTA). Because not all post-operative imaging findings result in disability or pain for the patient, we also emphasize our approach and experience regarding how best to define imaging abnormalities after rotator cuff surgery. IMAGING APPROACHA protocol for the imaging of the post-operative shoulder always begins with radiography of the shoulder. The purpose of the radiograph is not only to detect obvious osseous complications, but also to identify the type of surgical procedure performed ...

Magnetic resonance imaging (MRI) evaluation of the postoperative shoulder presents technical and diagnostic challenges related to imaging artifacts from hardware and micrometallic shavings, postsurgical scarring, and morphological alterations. Improved visualization of postoperative shoulder anatomy and pathology can be obtained with the use of metal artifact reduction techniques as well as MR arthrography. In this article we review the MR techniques that are designed to address these technical and diagnostic challenges, and we discuss the definitions and indications, normal MRI appearance, and complications of routine surgical procedures for treatment of injuries to the rotator cuff, labral ligamentous complex, and biceps tendon.
