DHS Lag Screw Pediatrics

The DHS Lag Screw Pediatrics is an orthopedic implant used in the Dynamic Hip Screw system for pediatric proximal femoral fracture repair. Surgeons insert it into the femoral head, where it engages the DHS side plate barrel. This design allows the bone fragments to slide axially during load bearing, so they settle into a compressed, stable position as healing progresses.

How It Works

The lag screw is cannulated. This means surgeons can place it over a guide wire for accurate positioning under fluoroscopic guidance. The distal thread grips the cancellous bone inside the femoral head. Meanwhile, the smooth proximal shaft slides freely within the plate barrel, enabling the controlled compression that gives the DHS system its name.

Pediatric Application

Orthopedic surgeons use this implant to fix pediatric proximal femoral fractures, including intertrochanteric and subtrochanteric types. In pediatric cases, screw length selection also takes physis preservation into account. As a result, a wide range of lengths is essential for this application. The lag screw works as part of a full DHS construct that also includes a side plate and cortical screws along the femoral shaft.

Material

Surgeons and procurement teams can choose from two material options:

• High-quality premium German stainless steel
• Titanium

Available Sizes

Thread Diameter:

• 12.5 mm
• 12.7 mm

Length Options (mm):
50 · 55 · 60 · 65 · 70 · 75 · 80 · 85 · 90 · 95 · 100 · 105 · 110 · 115 · 120 · 125 · 130 · 135 · 140 · 145

Choosing the Right Size

The two diameter options — 12.5 mm and 12.7 mm — match different DHS system configurations and side plate types. The length range runs from 50 mm to 145 mm in 5 mm steps. This broad selection covers the range of anatomical sizes surgeons encounter in pediatric patients. The treating surgeon determines the appropriate length based on intraoperative measurement and imaging.

Summary

The DHS Lag Screw Pediatrics is available in two thread diameters and twenty length options. Surgeons can also choose between premium German stainless steel and titanium. Together, these options support a wide range of pediatric proximal femoral fracture cases within the Dynamic Hip Screw system.
