Synthes 338.21 DHS/DCS Guide Shaft – Lag Screw 4-1/4 Inch Insertion Orthopedic Instrument

The Synthes 338.21 DHS/DCS Guide Shaft is a precision-engineered instrument that serves as a critical link in the Dynamic Hip Screw (DHS) and Dynamic Condylar Screw (DCS) fracture fixation systems. This guide shaft is designed to maintain exact axial alignment during the insertion of lag screws into the proximal or distal femur.

 

Measuring 4-1/4 inches, this shaft works in tandem with the DHS/DCS short coupling screw and the centering sleeve to create a stable insertion assembly. By providing a rigid mechanical interface, it ensures that the lag screw follows the intended trajectory established by the initial guide wire, reducing intraoperative variability. Manufactured from high-grade surgical stainless steel, the 338.21 is built to withstand high-torque maneuvers and repeated sterilization cycles in a trauma environment.
