Patient-specific instrumentation for total shoulder arthroplasty

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering
• Implant Technology

Background:

• Shoulder arthroplasty complications often stem from glenoid component malposition.
• Minimizing glenoid component risk is crucial for successful shoulder replacement outcomes.
• Pre-operative planning and advanced instrumentation aim to reduce these risks.

Purpose of the Study:

• To describe the pre-operative planning and surgical technique for patient-specific instrumentation (PSI) in total shoulder arthroplasty.
• To highlight the benefits of PSI in improving glenoid component accuracy.
• To review the current literature and author's experience with PSI for shoulder replacement.

Main Methods:

• Patient-specific instrumentation (PSI) developed as an alternative to navigation systems.
• Application of PSI, originally for total knee arthroplasty, now validated for shoulder replacements.
• Detailed description of pre-operative planning and surgical technique based on author's experience and literature review.

Main Results:

• PSI offers increased accuracy in glenoid component placement.
• Improved accuracy with PSI enhances the likelihood of optimal surgical outcomes.
• PSI is a valid option for shoulder replacements, addressing key risks.

Conclusions:

• Patient-specific instrumentation is a valuable tool for precise glenoid component placement in shoulder arthroplasty.
• This technique can mitigate common complications associated with glenoid component malposition.
• PSI contributes to improved functional outcomes following total shoulder replacement.
