摘要

A bilateral dynamic external distractor is disclosed for the treatment of complex fracture luxations of the PIP of the hand. The distractor comprises two setscrews, one left proximal guide block, one right proximal guide block, two threaded rods, two distal guide blocks, and two optional alignment guide clips. The left and right distal guide blocks each comprise a threaded passage, and the first threaded rod extends between the right proximal guide block and the right distal guide block, and the second threaded rod extends between the left proximal guide block and the left distal guide block. Furthermore, rotation of the first and second threaded rods causes the left and right distal guide blocks to move relative to the left and right proximal guide blocks along an axis of the first and second threaded rods.
