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.
舟月三角骨（STT）骨关节炎与静态背侧插入节段不稳定（DISI）之间的关系受到怀疑。对697例50岁以上患者的腕部X线片进行了调查。在63例腕部中单独发现了STT骨关节炎，在4例腕部中发现了孤立的DISI。在16例腕部中发现了两者并存的情况。这具有统计学意义（0.02 < P < 0.05）。静态DISI很可能是STT骨关节炎的结果。
