Synthes 314.21 Wrench for Nut 219.96 5-7/8"

Synthes Wrench for Nut 219.96 | 5-7/8" Length | 314.21

The Synthes 314.21 is a specialized orthopedic manual instrument engineered for the precise manipulation of the 219.96 Nut. This nut is a critical component used in conjunction with 4.5mm cortex screws in complex fracture fixations where standard screw purchase in bone is insufficient or where a bolt-and-nut construct is required for maximum stability.

With an overall length of 5-7/8 inches (~150mm), this wrench provides the necessary mechanical leverage to apply controlled torque to the nut without over-tightening. The business end of the tool is precision-machined to match the specific hexagonal geometry of the 219.96 nut, ensuring a "no-slip" interface that protects the hardware from rounding or deformation.

Key Specifications

• Manufacturer: Synthes (DePuy Synthes)

• Model / REF: 314.21

• Compatibility: Specifically for Synthes Nut 219.96 (4.5mm System)

• Overall Length: 5-7/8 inches (15.2 cm)

• Material: High-Grade Surgical Stainless Steel

• Finish: Satin / Polished (to reduce glare under OR lights)

• Quantity: 1 Each

Technical & Clinical Advantages

• Optimized Mechanical Leverage: The 5-7/8" handle is calibrated to provide the surgeon with an ideal balance of reach and rotational force. This is particularly useful in deep surgical sites where manual nut placement and tightening are required.

• Precision Geometric Fit: The wrench socket is engineered to tight tolerances, ensuring that the nut is held securely during the initial threading and final tightening phases. This reduces the risk of the nut falling into the surgical wound.

• Ergonomic Profile: The slender, rounded handle design allows for comfortable "palm-in-hand" rotation, reducing hand fatigue during long reconstructive procedures.

• Surgical Steel Durability: Forged from vacuum-melted stainless steel, the 314.21 maintains its structural integrity and resistance to torsional stress through repeated high-temperature sterilization cycles.

Applications

• Complex Fracture Fixation: Securing 4.5mm cortex screws using the 219.96 nut in scenarios with significant bone loss or poor bone quality.

• Pelvic & Acetabular Surgery: Maneuvering nuts in the restricted anatomical spaces of the pelvic ring.

• Hardware Removal / Revision: Providing the necessary grip to break the "cold-weld" of older hardware during retrieval in 2026.

• Orthopedic Salvage Procedures: Creating stable bolt-and-nut constructs for non-unions or mal-unions.

Condition & Quality Assurance

• Status: PRE-OWNED / REFURBISHED.

• Integrity: These instruments have been previously used in clinical settings. They show visible signs of wear consistent with standard surgical usage, such as minor surface scratches or dulling of the finish. However, they remain fully functional, with the socket geometry intact and the handle straight.

• Sterilization Note: This is a NON-STERILE, REUSABLE instrument. It MUST be thoroughly cleaned and sterilized via validated steam autoclave protocols in accordance with your facility's guidelines and Synthes’ Instructions for Use (IFU) prior to clinical application.

• Professional Standards: With over 25 years of experience in orthopedic logistics, Primis Medical ensures all pre-owned instruments are inspected for mechanical soundness and are free from structural defects.

Shipping & Handling

• Secure Logistics: Shipped in protective packaging to ensure the instrument remains in its verified functional state during transit.

• Fast Dispatch: Ships within 1 business day.
