Summary of "All Dynamic Hip Screw (DHS) Instruments explained"

Main Ideas and Concepts

Instrumentation Overview: The speaker introduces the various instruments required for DHS placement and their specific uses.
Angle Guide: Used for the placement of the guide wire for the Leg Screw. Ensures the guide wire is positioned correctly in the desired direction.
Direct Measuring Device: Measures the length of the Leg Screw needed based on the guide wire's position.
Triple Reamer: There are two types: short barrel for screws less than 85 mm and long barrel for screws greater than 85 mm. Used to create a track for the Leg Screw.
Tapping Process: Involves using a tap sleeve and a tap to create threads in the bone for the Leg Screw.
Leg Screw Insertion: The Leg Screw is designed to fit into a coupling device, which is then inserted into the bone. A T-wrench is used to rotate and insert the Leg Screw properly.
Barrel Plate Placement: The Barrel Plate must be aligned with the Leg Screw and the lateral cortex of the femur. The correct Barrel Plate (short or long) is chosen based on the Leg Screw length.
Richard Screw (Compression Screw) Insertion: This screw is used to create compression at the fracture site after ensuring the plate is flush with the lateral cortex. It is crucial to insert lower screws first before tightening the Richard Screw.
Removal of Leg Screw: A non-cannulated coupling device is used for the removal of the Leg Screw, ensuring it can engage with the threads for effective extraction.
