title: An association between scapho-trapezio-trapezoid osteoarthritis and static dorsal intercalated segment instability.
abstract: A relationship between scapho-trapezio-trapezoid (STT) osteoarthritis and static dorsal intercalated segment instability (DISI) was suspected. The radiographs of 697 wrists in patients over 50 years were surveyed. In 63 wrists STT osteoarthritis was found in isolation, and isolated DISI was found in four wrists. A combination was found in 16 wrists. This was statistically significant (0.02 < P < 0.05). It is likely that the static DISI occurs as a consequence the STT osteoarthritis.
