Abstract

An external fixation system (10) comprising one or more rings (14), elongated member (16), extension fingers (18) with pin holders (52), wire holders (22), clamping assemblies (20), screws (24) or wire (26) for securing part of a bone (12), and rod connectors (174). The extension fingers (18) are positioned axially and radially along the elongated members (16). The pin holders (52) move axially along and radially around the extension fingers (18), and are secured in place using a one-hand operation which also secures the screw (24) in place. The screws (24) are secured to the pin holders (52) from a point which may be positioned and oriented with full spatial articulation in three dimensions. The rings (14) are provided with openings (104) composed of intersecting apertures (106) to decrease the spacing between available location. A lengthening-compression-distraction (LCD) bar (28) permits traction or compressive forces to be exerted on the bone (12), as well as dynamization for weight-bearing compression. Certain components of the LCD bar (28) can be reconfigured during fabrication to facilitate use in a tansport mode. The rod connector (174) joins two elongated members (16) at a selected and adjustable angle, and includes two open-ended U-collars (176, 178) stacked on a shaft (182) for rotation until the U-collars (176, 178) are compressed to clamp the elongaged members (16).
