Continuous distraction can be considered as an alternative method of thumb reconstruction after traumatic loss. This technique is applicable if at least two thirds of the metacarpal length are retained and the stump is well covered by soft tissue. Elongation up to 100% of the initial length is then realizable. For a good functional precision grip it is necessary for the reconstructed thumb to reach the nail root of the opposite side. There is normal tactile gnosis after distraction. The strength of power grip is not decreased. Impaired, however, is the skillfulness of pulp-to-pulp pinch. We report on our experience in 48 cases.
持续牵引可被视为创伤性拇指缺失后拇指重建的一种替代方法。如果掌骨长度至少保留三分之二且残端有良好的软组织覆盖，则该技术适用。然后可实现延长至初始长度的100%。为了实现良好的功能性精确抓握，重建的拇指必须到达对侧的指甲根部。牵引后触觉正常。强力抓握的力量不会减弱。然而，指尖对指尖捏取的技巧会受损。我们报告了48例患者的经验。
