Synthes 281.46 150° DHS Plate-Standard Barrel 6 Holes/110mm

Synthes 150° DHS Plate | Standard Barrel | 6 Holes | 110mm | 281.46

The Synthes 281.46 is a high-specialty implant within the Dynamic Hip Screw (DHS) System, specifically engineered for the stabilization of intertrochanteric and subtrochanteric fractures. This 6-hole plate features a steep 150° neck-shaft angle and an extended 110mm shaft length, offering a specialized valgus configuration for specific anatomical requirements or corrective osteotomies.

The DHS system remains the biomechanical "gold standard" for internal hip fixation. It allows the proximal femoral fragment to slide along a lag screw (sold separately) within the plate's barrel. This controlled collapse converts physiological loads into beneficial interfragmentary compression, which is vital for promoting bone union in the proximal femur.

Technical & Clinical Advantages

• 150° High-Angle Alignment: The 150° angle is utilized for patients with a highly valgus femoral neck or in cases requiring a valgus-producing osteotomy to treat femoral neck non-unions. Selecting the correct angle is critical to restoring proper biomechanical hip levers.

• Extended 6-Hole Shaft: The 110mm length provides a longer lever arm compared to standard 4-hole plates. This is essential for stabilizing fractures with subtrochanteric extension, providing additional screw purchase points in the femoral shaft to resist rotational and shear forces.

• Controlled Dynamic Compression: The precision-honed standard barrel allows the DHS lag screw to slide freely, ensuring postoperative fracture impaction and reducing the risk of the screw "cutting out" through the superior aspect of the femoral head.

• Low-Profile Plate Geometry: Engineered with beveled edges and a tapered distal end, the 281.46 minimizes soft-tissue irritation and facilitates easier submuscular insertion, particularly in minimally invasive surgical (MIS) approaches.

• 316L Stainless Steel Biocompatibility: Forged from vacuum-melted surgical steel, this plate provides the structural rigidity and fatigue resistance required to support weight-bearing loads during 2026 mobilization protocols.

Applications

• Intertrochanteric Fractures: Stabilization of fractures in patients with extreme valgus anatomy.

• Subtrochanteric Extensions: Providing extended shaft fixation where the fracture line extends distal to the lesser trochanter.

• Valgus Femoral Osteotomies: Correcting varus deformities or treating femoral neck pseudoarthrosis (non-union).

• Proximal Femoral Trauma: Cases requiring a robust lateral buttress with multiple points of distal shaft fixation.

Condition & Quality Assurance

• Status: NEW — Factory Sealed.

• Integrity: The implant is securely housed within its original manufacturer's packaging. Both inner and outer seals are intact, ensuring full material integrity and suitability for surgical use.
