Early Severe Complications of Total CM1 Replacement with Maïa Prosthesis

During the last 18 months the first author performed 42 total cm1 replacements using the Maïa prosthesis. We will report early severe complications – 2 dislocations of the stem from the cup, 1 loosening of the cup and 1 cup dislocation.

We will discuss the reasons for these complications, their treatment and outcomes.

These four patients were re-operated and have a good functioning hand.

We believe that these complications were a part of the learning curve. We expect better results in the future.
