Zimmer Gets Personal with Patient Specific Instruments

Reverse shoulder arthroplasty is associated with multiple complications, the most common of which is related to glenoid component failure. Successful fixation of the glenoid component has been shown to be dependent on component design, cement techniques, and instrumentation. Zimmer’s newest offering, the Patient Specific Instruments (PSI) Shoulder System has the potential to help reduce glenoid component failure through patient-specific surgical instrument guides. Using 3 -D visualization software to create customized plans for each patient, these patient-specific surgical instrument guides can help surgeons to improve implant placement. As Vice President and General Manager, Roberto Munozto explained, this helps “plan the glenoid side of the surgery with the patient’s unique anatomy in full view and functional needs in mind.” The use of both 3 -D preoperative planning with patient and implant-specific instrumentation has been shown in clinical studies to help with optimal implant design and placement which can lead to improved outcomes.

Zimmer also offers Patient Specific Instruments for the knee. Similar to the PSI Shoulder system, the surgeon can view the patient’s anatomy preoperatively and customize the surgical plan, including implant selection and size. 10.17The ability to better plan surgery around each patient’s particularly anatomy can help ensure better implant placement which is key for implant longevity as a study in the Journal of Bone and Joint Surgery found. Researchers discovered that alignment errors greater than 3% in artificial knee procedures are associated with implant failures. The use of PSI systems for knee replacement procedures claim to improve these alignment issues. The Patient Specific Instruments Planner software is available for the Unicompartmental High Flex Knee System from Zimmer.
