| 摘要 |
The present invention is directed to a device for fixation of a bone fracture. The device comprises at least one distal pin having a mounting end for insertion on a distal side of the fracture, at least one proximal pin having a mounting end for insertion on a proximal side of the fracture, a distal member attached to the distal pins, a proximal member attached to the proximal pins and slideably connected to the distal member for reducing or distracting the bone fracture, a distraction assembly for controlling the movement between the proximal and distal members, and a removable engagement element. The distraction assembly has two modes of operation: an active configuration and an inactive configuration. In the active configuration, incremental relative sliding movement between the proximal and distal members is allowed, and, in the inactive configuration, free relative sliding movement between the proximal and distal members is allowed. The engagement element operatively engages the distraction assembly in the inactive configuration. Removal of the engagement element places the distraction assembly in the active configuration. |
