dhs instrument set

SAFEX INCs Dynamic Hip Screw (DHS) is an orthopedic implant used in the surgical treatment of certain hip fractures, particularly fractures of the proximal femur. The DHS system includes a variety of specialized instruments and implants designed to facilitate the placement of the hip screw and achieve stable fixation of the fractured bone. The DHS implant is often used in cases of intertrochanteric and subtrochanteric fractures.

A typical DHS instrument set may include the following components:

1. DHS Plate: The dynamic hip screw plate is a large, angled plate that is affixed to the lateral aspect of the proximal femur. It usually has multiple holes to allow for fixation with screws.

2. DHS Screw: The dynamic hip screw itself is a large screw that is inserted into the femoral head, passing through the plate. The screw has a dynamic feature, allowing controlled sliding of the femoral head along the screw, which aids in load-sharing and promotes healing.

3. Guide Wire: A guide wire is used to guide the placement of the hip screw. It is typically inserted into the femoral head and neck under fluoroscopic guidance before the actual screw is introduced.

4. Drill Bits: Various drill bits are used to create holes in the bone for the insertion of screws. These may include cortical and cancellous drill bits.

5. Depth Gauge: A depth gauge is used to measure the depth of the drill holes, ensuring proper placement of the screws.

6. Tap: A tap is used to create threads in the bone before inserting the actual screws.

7. Lag Screw: In some cases, a lag screw may be used instead of or in addition to the dynamic hip screw. The lag screw compresses the fracture surfaces, promoting stability.

8. Instrumentation for Plate and Screw Placement: This includes instruments like screwdrivers, screw holders, and plate benders to facilitate the correct positioning and fixation of the plate and screws.

It's important to note that the specific contents of a DHS instrument set can vary between manufacturers, and surgeons may choose instruments based on their preferences and the patient's specific anatomy.
