What is this trial about?
This is the second phase of a clinical study to assess MP hyperextension in CMC
arthritis. In the first phase, submitted for publication, the investigators demonstrated
that there is poor correlation between dynamic control of the MP joint and the amount of
passive hyperextension preoperatively in a sample of patients with CMC arthritis.
What are the participation requirements?
