Synthes 281.36 145° DHS Plate-Standard Barrel 6 Holes/110mm

Synthes 145° DHS Plate | Standard Barrel | 6 Holes | 110mm | 281.36

The Synthes 281.36 is a high-performance implant within the Dynamic Hip Screw (DHS) System, specifically engineered for the stabilization of intertrochanteric, subtrochanteric, and basilar neck fractures. This 6-hole plate features a 145° neck-shaft angle and an extended 110mm shaft length, providing a robust lateral buttress for patients with steep femoral neck anatomy.

The DHS system is the biomechanical benchmark 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, which is essential for promoting bone union and preventing hardware "cut-out" in the proximal femur.

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, shifting stress from the implant to the bone to facilitate rapid healing.

• 145° High-Angle Geometry: The 145° angle is designed for patients with more upright (valgus) femoral neck anatomy. Correct angle selection is vital to restoring the patient's natural hip mechanics and avoiding limb length discrepancy post-surgery.

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

• 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 Design: Featuring beveled edges and a tapered distal end, the 281.36 minimizes soft-tissue irritation and facilitates submuscular insertion, reducing surgical trauma.

Applications

• Intertrochanteric Fractures: Stabilization of fractures in patients with valgus femoral neck geometry.

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

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

• Complex Proximal Femoral Trauma: Cases requiring a long 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.

• 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.
