A retrospective cross-sectional study was performed focusing on identifying the incidence of malpositioned components in conventional TSA and RSA.
Quantitative analysis demonstrated that the majority of glenoid and humeral components were malpositioned:1
51%
Glenoid malposition - TSA
93%
Glenoid malposition - RSA
57%
Humeral malposition - TSA
62%
Humeral malposition - RSA
But, a robotic system, like ROSA® Shoulder, for anatomic and reverse shoulder replacements could help mitigate malpositioning.
Precision placement with improved consistency over conventional instrumentation.2
Delivering real-time data to execute and validate your personalized TSA surgical plan for accurate glenoid and humeral component placement,2 while addressing known risks associated with component malposition3-6 in anatomic and reverse shoulder arthroplasty.

Why Surgeons Choose ROSA® Shoulder:
Complete solution from pre-op to post-op
Industry’s first robotic system to support both glenoid and humeral preparation for anatomic and reverse techniques.
Optimal Flexibility
The flexibility to adjust surgical plan on demand and intra-operatively switch from an anatomic total shoulder to a reverse shoulder if needed.
Validated Reaming
Provides live feedback allowing for glenoid ream depth control and intra-operative validation of cuts. For protection, the Robotic Arm will automatically stop reaming when the planned reaming depth is met.
Bolstering Confidence
Continual cross-validation to reduce reliance on manual estimation, helping verify bone registration, avoid rotator cuff insertion resection and support surgeon confidence.
