Trial Summary
What is the purpose of this trial?The purpose of this study is to examine the rotator cuff muscles in your shoulder at one and two year post total shoulder replacement surgery.
Do I need to stop taking my current medications for this trial?
The trial information does not specify whether you need to stop taking your current medications.
What data supports the effectiveness of CT scans after shoulder replacement for shoulder osteoarthritis?
CT scans can help identify complications after shoulder replacement, such as mechanical issues and infections, which can guide further treatment and improve outcomes.
12345Is it safe to have a CT scan after shoulder replacement surgery?
CT scans are generally safe and commonly used to check for complications after shoulder replacement surgery. They help doctors see if there are any issues with the shoulder implant, like loosening or infection, without causing harm to the patient.
12678How is the CT scan treatment different for shoulder osteoarthritis after replacement surgery?
CT scans are used to precisely evaluate the position and stability of shoulder implants after replacement surgery, which can help identify complications like loosening or infection that might not be visible with standard X-rays. This makes CT scans a valuable tool for diagnosing issues that cause pain or dysfunction in patients with shoulder replacements.

SPECT/CT in Postoperative Shoulder Pain. [2018]Over the last 2 decades, the incidence of prosthetic shoulder replacements has increased considerably, leading to a rising number of complications and reoperations. In this article, we review how SPECT/CT can be of significant clinical value for shoulder surgeons. Bone SPECT/CT can provide the correct diagnosis for different types of mechanical complications: glenoiditis after hemiarthroplasty, glenoidal loosening after total shoulder arthroplasty, and scapular notching after reverse shoulder arthroplasty. Various nuclear medicine methods are available for detecting prosthesis infection. In our experience, labeled white blood cell scintigraphy combined with bone marrow scintigraphy is the reference standard. FDG-PET may be useful in case of discordance between the white blood cell scan and the clinical context and complementary test results.

Osteoporosis and shoulder osteoarthritis: incidence, risk factors, and surgical implications. [2016]Patients with osteoarthritis undergoing shoulder arthroplasty may suffer from osteoporosis. The purpose of this study was to determine whether computed tomography (CT)-derived Hounsfield unit (HU) measurements correlate with bone mineral density (BMD) and whether these data could predict implant size and fixation choice.
Shoulder joint arthroplasty in young patients: Analysis of 8742 patients from the Australian Orthopaedic Association National Joint Replacement Registry. [2023]Shoulder replacement is a reliable treatment for the relief of pain and improvement of function in patients with glenohumeral arthritis, rotator cuff arthropathy, osteonecrosis and fracture. Limited data is available comparing revision rates for the different types of shoulder replacement when used in younger patients. This study aims to compare the survivorship of hemi resurfacing, stemmed hemiarthroplasty, total shoulder arthroplasty and reverse total shoulder arthroplasty in younger patients using data from a large national arthroplasty registry.

[2023]Computed tomography (CT) is often utilized for both diagnostic and pre-operative planning purposes in shoulder arthroplasty. Our study reports on the incidence of pulmonary findings in our pre-operative shoulder arthroplasty population over 14 years at our institution.
Core Set of Radiographic Parameters for Shoulder Arthroplasty Monitoring: Criteria Defined by an International Delphi Consensus Process. [2022]Some unfavorable local events following shoulder arthroplasty occur without the patient experiencing symptoms and yet may be detected on diagnostic imaging, thereby serving as indicators of complications that may require revision. Our aim was to create a standardized protocol for an image-based monitoring process for assessing patients who are asymptomatic following shoulder arthroplasty.
Imaging of shoulder arthroplasties and their complications: a pictorial review. [2020]Currently, an increasing number of patients benefit from shoulder prosthesis implantation. Radiologists are therefore more often confronted with imaging examinations involving shoulder arthroplasty, whether during a dedicated examination or incidentally. Standard radiography is the first-line imaging modality in the follow-up of these implants, before the possible use of cross-sectional imaging modalities (computed tomography and magnetic resonance imaging), ultrasound, or nuclear medicine examinations. Shoulder arthroplasties are divided into three categories: reverse shoulder arthroplasty, total shoulder arthroplasty, and partial shoulder joint replacement (including humeral hemiarthroplasty and humeral head resurfacing arthroplasty). Each of these prostheses can present complications, either shared by all types of arthroplasty or specific to each. Infection, periprosthetic fractures, humeral component loosening, heterotopic ossification, implant failure, and nerve injury can affect all types of prostheses. Instability, scapular notching, and acromial fractures can be identified after reverse shoulder arthroplasty implantation. Glenoid component loosening and rotator cuff tear are specific complications of total shoulder arthroplasty. Progressive wear of the native glenoid is the only specific complication observed in partial shoulder joint replacement. Knowledge of different types of shoulder prostheses and their complications' radiological signs is crucial for the radiologist to initiate prompt and adequate management.
Arthroscopic assessment of glenoid component loosening after total shoulder arthroplasty. [2022]Component loosening after total shoulder arthroplasty is uncommon. Evaluation of the painful total shoulder can be difficult. Radiography may not be accurate enough to assess component loosening. A retrospective study of nine patients undergoing arthroscopy and later open surgery to confirm arthroscopic findings was undertaken. Plain radiographs correlated with component loosening in two of six patients. Arthrography correlated in one of three patients. Arthroscopy accurately evaluated glenoid component loosening in all patients with this problem. After shoulder arthroplasty patients who develop increasing pain and loss of motion require further evaluation. Radiographic studies appear to be less sensitive than arthroscopic techniques in the evaluation of glenoid component loosening. Arthroscopy has proved to be a valuable technique for the evaluation of patients with painful total shoulder arthroplasty.
Sequential 3-dimensional computed tomography analysis of implant position following total shoulder arthroplasty. [2018]Detection of postoperative component position and implant shift following total shoulder arthroplasty (TSA) can be challenging using routine imaging. The purpose of this study was to evaluate glenoid component position over time using 3-dimensional computed tomography (CT) analysis with minimum 2-year follow-up.
