Post Market Clinical Follow-Up TOUCH® CMC 1

Because severe pain, weakened pinch and grip strength produce functional disabilities, the basal joint of the thumb is the most common site of surgical reconstruction in the upper limb due to OA. The cement-free dual mobility Touch® prosthesis consists of a metacarpal implant (stem), a trapezium implant (cup), and a connection implant (neck). The main objective of this study is to describe the performance and safety of the Touch® prosthesis used with its instruments set in accordance with its intention and CE marking in force. Performance and safety will be assessed over the short and long term in accordance with the life cycle of the Touch® prosthesis.
