These authors created glenoid defects in 10 cadaveric shoulders. Computed tomography images were used to plan reversed shoulder arthroplasty and design patient-specific glenoid components. A patient-specific positioning guide was designed for 5 specimens. The remaining 5 specimens were implanted without the guide.
The patient-specific positioning guide significantly reduced the angular deviations from the planned glenoid implant positioning (P < .05) but not offset, version, inclination or roll. It improved the positioning of the screws and the postoperative total intraosseous screw length.
Comment: This article does not present the learning curve, incremental cost or incremental time associated with the use of patient-specific instrumentation in this cadaver study to weigh against the difference in the two groups as shown below.
