Nonspanning Distal Radius Fixator

Treatment of fractures of the distal radius has been proven to be advantageous if spanning of the wrist joint is avoided. This allows for greater motion throughout the treatment resulting in improved range of motion, grip strength, and dexterity. The nonspanning Distal Radius Fixator provides such a nonbridging external fixator, creating a low-profile frame for increased patient comfort and the ability to perform daily activities.

The nonspanning Distal Radius Fixator consists of a small adjustable clamp, nonspanning, MR safe. It locks on to two 4.0 mm Schanz Screws spaced 20 mm apart. The 4.0 mm carbon fiber rod slides into a through hole in the clamp with a set screw tightening point to established the desired length. A ball joint in the clamp then provides for ulnar/radial as well as volar/dorsal deviation of the rod. To create lower profile frames, the nonspanning Distal Radius Fixator includes three shorter length Schanz screws65 mm lengths in both 4.0/2.5 mm size (with a trocar tip) and the 4.0/3.0 mm size (with a self-drilling tip), and an 80 mm length in the 4.0/2.5 mm size (with a trocar tip).

The 4.0 mm curved carbon fiber rods match the axial curvature of the wrist. They are available in 60, 90, 120, or 180 arcs to be used for fixation of the distal fragment.

The 4.0 mm angled T-bar carbon fiber rods create the same angle as the curved rods, with the addition of a rod extending perpendicularly. The material allows a frame to be constructed with a rod centred on the dorsal aspect of the wrist without sacrificing the C-arm image in the dorsal/palmar view. The angled T-bar fiber rods will be available in 80 mm (length) 50 mm (width), 80 120 mm, 110 50 mm, and 110 120 mm. Both the curved and angled T-bar fiber rods can be used as part of a delta frame construct.

Additional instruments such as drill sleeves, drill guides, and trocars are included in the set.

Small Universal Chuck with T-Handle

The Small Universal Chuck with T-Handle is used to insert Schanz screws or wires from 1.0 - 6.0 mm diameters. The size of the T-Handle has been reduced for lighter weight and easier handling and will be available for all External Fixation Systems.
