A Large Fragment Instrument Set is a comprehensive collection of orthopedic trauma instruments that supports internal fixation procedures involving large cortical and cancellous screws, typically in the 4.5 mm and 6.5 mm ranges. In practice, these sets bring together the drilling, tapping, measuring, bone-holding, retraction, and plate-contouring instruments that orthopedic surgical teams require when working with large fragment plate and screw systems.
This particular set features high-quality premium German stainless steel instruments and comes complete with an organized surgical sterilization box, making it a practical choice for hospitals, surgical centers, and orthopedic instrument distributors. Furthermore, the configuration matches the product images and covers 26 instrument categories across the full range of large fragment fixation instrumentation.

Instrument Categories
Drilling and Drill-Guiding Instruments
This set supplies four drill bits — two at Ø3.2 mm and two at Ø4.5 mm, each 150 mm in length — for preparing bone holes at the sizes appropriate for large cortical and cancellous screw systems. In addition, the Universal Drill Guide (Ø3.2/4.5) and Double Drill Sleeve (Ø3.2/6.5) deliver controlled hole placement and help protect surrounding soft tissue during drilling. The 4.5 mm DCP Drill Guide with neutral and load modes serves dynamic compression plate systems specifically. Finally, a Countersink Ø8 prepares the screw-entry site before insertion.
Tapping Instruments
The Tap Cortex 4.5 mm and Tap Cancellous 6.5 mm each create threads in drilled holes before screw placement. Together, they cover the two standard large fragment screw sizes that these systems typically require.
Measurement Instruments
A Depth Gauge with a 0–90 mm range lets the surgical team measure hole depth and select the appropriate screw length. Complementing it, three bending templates — in sizes 11×120 mm, 12×155 mm, and 12×212 mm — provide contouring references when the team shapes plates to bone anatomy.
Reduction and Bone-Holding Instruments
For fragment manipulation and provisional fixation, the set offers two ratchet-type reduction forceps at 210 mm — one with pointed jaws and one with a serrated jaw — giving the surgical team two grip options for different tissue situations. Additionally, two Self-Centering Bone Holding Forceps at 260 mm maintain stable bone purchase during fixation. A Screw Forceps rounds out this group by supporting controlled screw handling.
Retraction and Periosteal Elevation Instruments
Two Hohmann Retractors at 44 mm width maintain operative field exposure throughout the procedure. In addition, a Periosteal Elevator (8 mm, round tip) and a Periosteal Elevator (16 mm, flat blade) handle soft tissue elevation from bone surfaces during both approach and fixation.
Screw Insertion and Removal Instruments
A Screwdriver with Hexagonal 3.5 mm drive and a Screwdriver Shaft 4.5 together handle primary screw insertion tasks. The Quick Coupling T-Handle adds versatility by coupling to taps, drills, and other instruments in the set. Moreover, the Extraction Screw for Hexagonal 3.5 mm (conical) addresses screw removal when the situation requires it.
Plate Contouring Instruments
The Bending Iron (L/R) lets the surgical team contour plates to match bone surface geometry directly during the procedure. To support this, the three bending templates help pre-shape plates to common configurations before application.
Storage and Sterilization
Finally, a Surgical Sterilization Box organizes and protects the full instrument set and simplifies sterilization processing between procedures.

Materials and Construction
Sami’s Instruments manufactures the instruments in this set from high-quality premium German stainless steel. The surgical instrument industry widely favors German-origin stainless steel for its workability, corrosion resistance, and suitability for repeated sterilization processing. However, the manufacturer does not state a specific steel grade; consequently, buyers who require grade-specific material certification should confirm this detail directly with the supplier.
The set also comes with a Surgical Sterilization Box for organized instrument storage. Because sterilization method compatibility and processing requirements can vary, buyers should verify these specifics with the supplier before use.
