Synthes 281.54 135° DHS Plate-Short Barrel 4 Holes/78mm

Synthes 135° DHS Plate | Short Barrel | 4 Holes | 78mm | 281.54

The Synthes 281.54 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 standard 135° neck-shaft angle combined with a short barrel configuration, making it the primary choice for patients with smaller femoral anatomy or those requiring a shorter lag screw trajectory.

The DHS system is the global biomechanical 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 weight-bearing loads into beneficial interfragmentary compression, promoting primary bone healing and reducing the risk of hardware "cut-out."

Technical & Clinical Advantages

• Short Barrel Optimization: The 25mm short barrel is designed to prevent "bottoming out" when using shorter lag screws (typically 75mm or less). This is critical for patients with a narrow femoral neck or small stature, ensuring the sliding mechanism remains functional throughout the healing process.

• Controlled Dynamic Compression: The precision-honed barrel allows the DHS lag screw to slide freely, facilitating postoperative fracture impaction. This shifts the mechanical load from the implant to the bone, which is vital for achieving stable union in 2026 geriatric trauma protocols.

• Standard 135° Geometry: The 135° angle matches the average human femoral neck-shaft inclination, allowing for anatomical restoration of hip mechanics and helping to maintain equal limb length post-surgery.

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

• Low-Profile Plate Design: Featuring beveled edges and a tapered distal end, the 281.54 minimizes soft-tissue irritation and facilitates easier submuscular insertion, reducing surgical trauma.

Applications

• Intertrochanteric Fractures: Stabilization of stable and unstable pertrochanteric fractures in smaller-stature patients.

• Basilar Neck Fractures: Providing rotational stability and axial compression when used with a sliding lag screw.

• Short-Neck Anatomy: Cases where a standard 38mm barrel would interfere with the lag screw threads or provide insufficient sliding room.

• Trauma Reconstruction: Providing a rigid lateral buttress for proximal femoral fractures.

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.
