The scaphotrapeziotrapezoid (STT) joint is a dome shaped joint in the radial wrist that is
important in transfer of load from the thumb and radial hand to the scaphoid and the
radioscaphoid and scaphocapitate joints. Arthritis in this joint is the second most common
degenerative arthritis in the wrist, reported in 15% of wrist radiographs. The true incidence
of arthritis in the STT joint however is unknown though we assume that most cases of
arthritis are not clinically significant. Furthermore, the clinical and biomechanical
significance of arthritis in this joint is unclear. The investigators' clinical impression is
that the incidence of STT joint arthritis is inversely related to that of radiocarpal joint
arthritis. In an ongoing study, we are examining the relationship between STT joint arthritis
and radiocarpal joint arthritis on radiographs.
We suggest that STT joint arthritis alters the biomechanics of the wrist by limiting movement
of the scaphoid within the STT joint thereby protecting the wrist from radiocarpal arthritis
by limiting instability of the scaphoid.
The specific aims of this pilot study are to evaluate the movement of the arthritic scaphoid
within the STT joint using a computer-generated model based on CT scan of the wrist and to
compare this model with the already established model of the normal STT joint.
The investigators' hypothesis is that there is significantly less motion in the arthritic STT
joint.
