Skeletal Radiol 2021; 50:761-770. [PMID: 32978678 DOI: 10.1007/s00256-020-03607-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/29/2020] [Revised: 09/07/2020] [Accepted: 09/10/2020] [Indexed: 02/02/2023]
Abstract
OBJECTIVE To identify the morphological characteristics of the acromion and subacromial bursal space after arthroscopic acromioplasty using magnetic resonance imaging (MRI). MATERIALS AND METHODS One hundred patients who received arthroscopic rotator cuff repair and acromioplasty each received at least three MRI examinations (preoperative, first immediate postoperative, and second follow-up imaging between 8 months and 1 year postoperatively). Changes over time in the thickness and morphology of the postoperative acromion as well as the subacromial bursal space were assessed. Clinical and radiological parameters were also analyzed to identify any association with changes in acromial morphology. RESULTS Despite minimal acromial thinning observed at the first immediate postoperative state, the acromions showed significant thinning at the second postoperative MRI, with a mean reduction of 32%. Along with acromial thinning, an exaggerated concave contour of the acromial undersurface was observed in some patients. In the subacromial space, a loculated fluid collection developed in 91% of the patients at the second postoperative follow-up. No statistically significant association was noted between postoperative acromial thickness change and clinical or radiological factors (P value > 0.05). CONCLUSION A significant delayed reduction in acromial thickness within approximately 1 year of arthroscopic acromioplasty is thought to be a normal postoperative feature. The simultaneous collection of a loculated, cyst-like fluid in the subacromial bursal space may be an important associated factor of postoperative acromial thinning.

Abstract
Imaging has a paramount role in postsurgical assessment. Radiologists need to be familiar with the different surgical procedures to be able to identify expected postsurgical appearances and also detect potential complications. This article reviews the indications, normal expected postsurgical appearances, and complications of the most frequently used surgical procedures in the shoulder, elbow, and wrist. The emphasis is on points that should not be overlooked in the surgical planning.

J Shoulder Elb Arthroplast 2019; 3:2471549219832442. [PMID: 34497946 PMCID: PMC8282130 DOI: 10.1177/2471549219832442] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2018] [Revised: 11/21/2018] [Accepted: 01/24/2019] [Indexed: 11/15/2022] Open
Abstract
Background The subscapularis tendon is commonly released during shoulder arthroplasty,
and its integrity and repair postoperatively have been shown important to
help maximize patient function. However, diagnosing subscapular tendon
failure can be difficult with magnetic resonance imaging secondary to metal
artifact as well as very costly. Purpose The purpose of this study was to assess the utility of ultrasound imaging in
evaluating subscapularis integrity at specific time points following
shoulder arthroplasty, in a blinded fashion. Secondarily, we report on the
correlation between the condition of the subscapularis and quality-of-life
outcome measures. Study Design Prospective case series. Methods Ultrasounds were completed preoperatively and postoperatively at 1 week as
well as at 1, 3, and 6 months. Each was read by a single musculoskeletal
radiologist and categorized as “intact,” “torn,” or “unclear.” Clinical
outcome was evaluated using the Western Ontario Osteoarthritis Shoulder
(WOOS) index at these same time points. Results The final study group consisted of 35 procedures in 33 patients (19 females
and 14 males, mean age 66 ± 9 years). Three patients had postoperative
subscapularis failures that were confirmed in the operating room at the time
of repair. Of 24 sonographs categorized as “unclear” in the postoperative
period, the majority (n = 12, 50%) were taken at 1 week. Compared to
preoperative scores, patients had lower WOOS scores at 1, 3, and 6 months
postoperatively (P < .001). Correlation analysis did not
reveal an association between the ultrasound readings and the WOOS scores
postoperatively. Conclusion The utility of ultrasound examination of the subscapularis tendon following
shoulder arthroplasty is limited by timing and may be most useful when used
by the physician within clinical context. Significant improvement was noted
in disease-specific quality-of-life scores regardless of the status of the
subscapularis tendon as read on ultrasound.

Abstract
Imaging interpretation of the postoperative shoulder is a challenging and difficult task for both the radiologist and the orthopedic surgeon. The increasing number of shoulder rotator cuff, labrum, and biceps tendon repairs performed in the United States also makes this task a frequent occurrence. Whether treatment is surgical or conservative, imaging plays a crucial role in patient care. Many imaging findings can be used to predict prognosis and functional outcomes, ultimately affecting treatment. In addition, evolving surgical techniques alter the normal anatomy and imaging appearance of the shoulder such that accepted findings proved to be pathologic in the preoperative setting cannot be as readily described as pathologic after surgery. An understanding of common surgical procedures of the shoulder can aid in recognizing normal expected postoperative findings and discerning common complications. Although magnetic resonance (MR) imaging and MR arthrography are widely used, implementing a multimodality imaging approach for evaluation of the postoperative shoulder can provide additional imaging information that may be decisive and vital to diagnosis. The high spatial resolution of both computed tomography with arthrography and ultrasonography makes them additional modalities to consider, especially when dealing with metal artifact. To provide an accurate radiologic interpretation of high clinical value, radiologists should approach the postoperative shoulder comprehensively with knowledge of the anatomy, surgical techniques and complications, clinical outcomes, and imaging pitfalls. ©RSNA, 2016.

Abstract
PURPOSE To evaluate the effectiveness of external rotation and active supination CT arthrography in postoperative evaluation by comparing it with neutral CT arthrography and analyzing its agreement with postoperative clinical results after the repair of type II superior labral anterior to posterior (SLAP) lesions. MATERIALS AND METHODS A total of 25 patients who had undergone CT arthrography in neutral, external rotation and active supination position at least 1 year after the arthroscopic repair of SLAP lesions were enrolled. Two radiologists independently evaluated the status of the repaired SLAP lesions with neutral CT arthrography and then with external rotation and active supination CT arthrography. RESULTS Five patients had residual symptoms and positive findings upon SLAP-specific examinations. Agreements between the presence of symptoms and radiologic diagnoses based on neutral CT arthrography were insignificant for reader 1 (κ = 0.138, p = n.s.) and significant for reader 2 (κ = 0.328, p = 0.027). However, agreements were highly significant in the analysis following the evaluation of external rotation and active supination CT arthrography for both readers (κ = 0.694, p < 0.001 in reader 1; κ = 0.783, p < 0.001 in reader 2). CONCLUSIONS The presence of contrast-filled gaps between the labrum and glenoid on neutral CT arthrography after SLAP repair is frequent with satisfactory clinical outcomes. Gaps without additional widening upon external rotation and active supination CT arthrography may suggest postoperatively stable biceps anchors, so this new method could minimize the overdiagnosis of recurrent SLAP lesions. Additional gap widening on external rotation and active supination CT arthrography could be related to a true recurrent SLAP lesion and the symptoms of the patients.

Abstract
As the incidence of shoulder arthroplasty continues to rise, the orthopedic shoulder surgeon will be increasingly faced with the difficult problem of evaluating a failed shoulder arthroplasty. The patient is usually dissatisfied with the outcome of the previous arthroplasty as a result of pain, but may complain of poor function due to limited range of motion or instability. A thorough and systematic approach is necessary so that the most appropriate treatment pathway can be initiated. A comprehensive history and physical examination are the first steps in the evaluation. Diagnostic studies are numerous and include laboratory values, plain radiography, computed tomography, ultrasound imaging, joint aspiration, nuclear scans, and electromyography. Common causes of early pain after shoulder arthroplasty include technical issues related to the surgery, such as malposition or improper sizing of the prosthesis, periprosthetic infection, neurologic injury, and complex regional pain syndrome. Pain presenting after a symptom-free interval may be related to chronic periprosthetic infection, component wear and loosening, glenoid erosion, rotator cuff degeneration, and fracture. Poor range of motion may result from inadequate postoperative rehabilitation, implant-related factors, and heterotopic ossification. Instability is generally caused by rotator cuff deficiency and implant-related factors. Unfortunately, determining the cause of a failed shoulder arthroplasty can be difficult, and in many situations, the source of pain and disability is multifactorial.

Abstract
Ultrasonography is a well-established and widely accepted modality for the evaluation of rotator cuff tears and injury to the biceps brachii tendon. Ultrasonography and magnetic resonance imaging have comparable sensitivity and specificity for diagnosing both full-thickness and partial-thickness rotator cuff tears. This article addresses the ultrasonographic diagnosis of abnormalities of the rotator cuff, rotator interval, and biceps brachii, with magnetic resonance imaging and arthroscopic correlation. Characteristic ultrasonographic findings as well as imaging pitfalls are reviewed.
