Synthes 145° DHS Plate | Standard Barrel | 4 Holes | 78mm | 281.34

The Synthes 281.34 is a specialized implant within the Dynamic Hip Screw (DHS) System, specifically engineered for the stabilization of intertrochanteric, subtrochanteric, and basilar neck fractures. This 4-hole plate features a 145° neck-shaft angle and a standard-length barrel, offering a steep anatomical configuration for patients with high-angle femoral neck geometry.

The DHS system is the biomechanical "gold standard" for internal hip fixation. It allows the femoral head fragment to slide along a lag screw (sold separately) within the plate's barrel. This controlled collapse converts physiological loading into beneficial interfragmentary compression, promoting secondary bone healing and reducing the risk of hardware "cut-out."

Technical & Clinical Advantages

• Dynamic Sliding Mechanism: The standard barrel is precision-honed to interface with the DHS lag screw. This allows for controlled postoperative shortening and impaction of the fracture, which is critical for stability in osteoporotic bone.

• 145° High-Angle Alignment: The 145° angle is specifically designed for patients with a more valgus proximal femoral anatomy. Selecting the correct angle is vital to restoring the patient's natural hip mechanics and ensuring equal limb length post-surgery.

• High-Fatigue 316L Stainless Steel: Forged from vacuum-melted surgical steel, this plate provides the structural rigidity needed to withstand cyclic loading during early 2026 mobilization protocols.

• Low-Profile Plate Geometry: The plate features beveled edges to minimize soft-tissue irritation and facilitate submuscular insertion, reducing surgical trauma for geriatric or high-BMI patients.

• Standard Barrel Support: The 38mm barrel length provides maximum internal support for the lag screw, preventing "toggle" and ensuring smooth sliding even under high stress.

Applications

• Intertrochanteric Fractures: Stabilization of stable and unstable pertrochanteric fractures.

• Subtrochanteric Fractures: Providing a rigid lateral buttress when used with supplemental fixation.

• Basilar Neck Fractures: Offering superior rotational stability compared to isolated cannulated screws.

• Valgus Osteotomies: Management of proximal femoral deformities requiring a high-angle correction.

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.

• Sterilization Note: This device is provided as a NON-STERILE implant. It MUST be properly cleaned and sterilized via validated steam autoclave protocols in accordance with facility guidelines and Synthes’ Instructions for Use (IFU) prior to clinical implantation.
