Leg Screw

Our DHS Lag Screw and Compression Screw System is engineered for high-precision sliding fixation of proximal femoral fractures, including intertrochanteric and basilar neck hip fractures. Designed to work seamlessly with a standard Dynamic Hip Screw (DHS) plate, this dual-component system allows for controlled dynamic axial collapse, pushing bone fragments together under physiological load to accelerate solid biological healing.

The primary Lag Screw features deep, aggressive bone threads at its tip to ensure maximum purchase in the femoral head, while its smooth, polished shaft telescopes smoothly inside the plate barrel. The matching Compression Screw threads into the base of the lag screw, allowing the surgeon to apply precise intraoperative manual compression across the fracture gap before weight-bearing begins. Both components are manufactured from highly electropolished, implant-grade Surgical Stainless Steel 316L or Titanium Alloy.

Key Features & Benefits

• Controlled Dynamic Telescoping: The ultra-smooth, precision-ground shaft ensures seamless gliding within the plate barrel, allowing safe postoperative fracture collapse.

• High-Anchorage Buttress Threads: Wide, aggressive threads provide strong mechanical purchase in the cancellous bone of the femoral head, preventing screw cut-out.

• Precise Intraoperative Compression: The heavy-duty compression screw allows for fine-tuned tightening to stabilize bone fragments before the patient leaves the operating room.

• Unrivaled Torsional & Bending Strength: Engineered to bear extreme early physiological forces across the hip joint without bending or fatigue.

• Mirror-Polished Biocompatibility: Superior electropolished finish significantly lowers friction, protects surrounding soft tissue, and reduces bacterial colonization.
