Bone Study: LRTI in patients with Thumb MP Hyperextension 

Thumb metacarpophalangeal hyperextension in an arthritic population

In this second phase of this prospective observational study we will enroll patients with MP hyperextension (backward extension of the thumb joint) preoperatively that their surgeon does not plan to treat surgically. We plan to assess a postoperative change in the control of the untreated thumb joint and collect data on the function of the thumb after surgery.
