Do I Need Computer-Navigated Shoulder Replacement Surgery?

Computer navigation can improve the precision of implant placement during shoulder replacement, especially on the socket side of the shoulder. However, not every patient requires navigation to have an excellent result.

Dr. Streit uses a planning-first approach to determine when advanced technology adds value and when standard surgical technique is sufficient.

What computer navigation does

Computer navigation uses preoperative imaging and intraoperative tracking to help guide implant placement during shoulder replacement surgery.

The technology can help the surgeon position the glenoid component more closely to a planned target, particularly in shoulders with deformity, bone loss, or unusual anatomy.

This is most relevant in reverse shoulder replacement and complex glenoid reconstruction, where socket position and fixation are critical.

When navigation may be useful

• Severe glenoid bone loss
• Complex arthritis with socket deformity
• Revision shoulder replacement
• Reverse shoulder replacement with difficult baseplate positioning
• Cases requiring augmented implants
• Unusual anatomy or prior fracture deformity

In these cases, navigation may improve confidence in implant position and help execute a complex preoperative plan.

What navigation cannot replace

Navigation is a tool. It does not replace surgical judgment, experience, implant selection, soft-tissue balancing, bone preparation, or management of unexpected findings during surgery.

A well-planned and well-executed shoulder replacement can be successful with or without navigation when the surgeon understands the anatomy and has a clear plan.

What this means for patients

Computer navigation may be valuable in selected cases, especially complex shoulder replacement and revision surgery. For routine cases, it may not be necessary.

The better question is not “Do I need navigation?” The better question is whether technology will meaningfully improve planning, accuracy, safety, or long-term implant performance for your specific shoulder.
