Reliability and accuracy of 3D preoperative planning software for glenoid implants in total shoulder arthroplasty

The use of preoperative planning to decrease costs and increase efficiency in the OR

“… 6 , 9 , 26 The accuracy of 3D preoperative planning has correctly predicted the size of SA components and glenoid measurements used intraoperatively. 16 , 17 , 19 , 20 , 21 , 23 , 29 Thus, it is possible to minimize the number of instruments and trays used in a shoulder arthroplasty procedure based on the use of preoperative planning.…”

“…has previously validated this software's ability to reliably predict and plan intraoperative implant selection with a great degree of accuracy using the same methodology described here. 20 , 21 …”

“…Careful preoperative planning can reliably measure pathology, guide intraoperative implant selection, and improve correction of pathology in shoulder arthroplasty. 17 , 20 In addition, three-dimensional preoperative planning software has demonstrated accuracy in predicting intraoperative implant selection in reverse shoulder arthroplasty (RSA) and total shoulder arthroplasty (TSA). 1 , 3 , 19 , 20 , 29 Additionally, 3D templating can potentially improve surgeon efficiency through quick and reproducible planning and reduce costs associated with bringing excess components such as surgical trays into the operating room.…”

The Reverse Shoulder Arthroplasty Angle in MRI: Impact of the Articular Cartilage in the Estimated Inclination of the Inferior Glenoid

“…RSA angle is widely used among shoulder surgeons for 2D and 3D preoperative planning of the glenoid baseplate. Though evidence suggests that magnetic resonance imaging (MRI) can accurately determine version and inclination in most cases, 11,12 available pre-operative planning software use only CT. 2,13 The articular cartilage of the glenoid is thicker at the periphery 14 and may be present in common RSA indications such as cuff tear arthropathy and fracture. To estimate glenoid inclination intraoperatively, surgical instrumentation is set at the inferior glenoid rim.…”

“…Pre-operative planning is key to achieve good results and avoid complications in reverse shoulder arthroplasty (RSA) surgery. [1][2][3] Superior inclination of the glenoid component has been associated with elevated risk of aseptic loosening and poor functional outcomes. 4,5 An inferior tilt between 0 and 10°is recommended to achieve good results and avoid the "rocking horse effect".…”
