Do patient-specific instruments improve glenoid component positioning compared to standard surgical instruments?
Patient-specific instrumentation and 3D planning may allow for better definition of pathology and more accurate execution of glenoid component positioning.
Novel three-dimensional preoperative planning, coupled with patient and implant-specific instrumentation, allows the surgeon to better define the preoperative pathology, select the optimal implant design and location, and then accurately execute the plan at the time of surgery.
Hendel et al. (Wed,) studied this question.
