Evaluation of lengthening in reverse shoulder arthroplasty comparing X-rays and computerised tomography

Abstract

Measurements on radiographs and CT scans are comparable in most of the cases. However, we observed some important variations that question the reliability of radiographic measurements in up to 20 % of cases. Therefore, a CT scan appears to be necessary in the event of postoperative complications (e.g., instability, neurological problems).

Postoperative Evaluation of Reduction Loss in Proximal Humeral Fractures: A Comparison of Plain Radiographs and Computed Tomography

“…Precise measurement of NSA is complicates because of internal and external rotations of the glenohumeral joint. Therefore, the reliability of measurements, using plain radiographs, is questionable. Due to the limitations of plain radiographs, it is important to find a new imaging technique to improve the reliability of the evaluation of these prognostic factors.…”

ESTES recommendations on proximal humerus fractures in the elderly

“…Cuff reports on the outcome of a prospective cohort study including 53 patients with proximal humerus fractures treated with either hemiarthroplasty or reverse shoulder arthroplasty [96]. Functional outcome and patient-reported satisfaction scores were lower after hemiarthroplasty [97][98][99][100][101][102][103][104]. Radiographic healing of the tuberosities occurred in 61% of the patients in the hemiarthroplasty group compared with 83% of the patients in the RSA group.…”
