Konica Minolta Healthcare is thrilled to share that the Emory Orthopedics upper extremity team, under the leadership of Dr. Eric R. Wagner, FAAOS, FAOA, presented [JS1.1]two posters at AAOS 2026 on the reliability of Dynamic Digital Radiography for in vivo SHR measurements post shoulder arthroscopy.
In the poster, “Measurement of Scapulohumeral Rhythm using a Dynamic Radiographic Technique: A Validation and Reliability Study,” DDR was performed on 22 reverse shoulder arthroplasty patients and measurements including the glenohumeral and scapulothoracic angles were captured and compared to values calculated from a 3D to 2D registration model. They report that DDR is a simple technique that is readily incorporated into clinical workflows whereas 3D imaging and modelling is a time-consuming and resource-restricted process.
The second DDR poster, “Is Premorbid Scapulohumeral Rhythm Restored with Anatomic or Reverse Shoulder Arthroplasty for Cuff-Intact Osteoarthritis? An In Vivo Dynamic Radiography Study,” discusses utilizing DDR to determine total range of scapula motion in patients after shoulder arthroplasty. The clinical significance of scapula motion in patients with glenohumeral osteoarthritis after shoulder arthroplasty is poorly understood. Despite similar average SHRs, the observed variability in SHR intervals hints that there is opportunity for improvement in prosthesis biomechanics.
