Synthes 309.200 Hollow Reamer-Complete for 2.0mm Screws

Synthes Hollow Reamer-Complete | For 2.0mm Screws | 3" Length | 309.200

The Synthes 309.200 is a specialized salvage instrument engineered for the difficult removal of 2.0mm cortex screws. It is a critical component of the Synthes Mini-Fragment Screw Removal Set, specifically designed for "worst-case" scenarios where a screw head is stripped, sheared off, or cold-welded to a plate, rendering standard drivers and extraction screws ineffective.

Unlike extraction screws that engage the internal drive or cannulation, the Hollow Reamer works by cutting a minimal circular trench around the perimeter of the screw shank. This "over-coring" technique releases the bone-to-thread interface, allowing the damaged hardware to be lifted out with minimal disruption to the surrounding cortical architecture.

Key Specifications

• Manufacturer: Synthes (DePuy Synthes)

• Model / REF: 309.200

• Compatibility: 2.0 mm Cortex Screws

• Overall Length: 3 inches (~76 mm)

• Material: Hardened Surgical-Grade Stainless Steel

• Shank Type: Quick Coupling (QC)

• Components included: Hollow Reamer Bit + Centering Pin (309.170)

• Quantity: 1 Each

Technical & Clinical Advantages

• Counter-Clockwise Cutting: The reamer is engineered with left-hand (reverse) cutting flutes. This ensures that as the tool cuts into the bone, the rotational friction actually encourages the screw to back out rather than driving it deeper into the fragment.

• Precision Centering: The system includes the 309.170 Centering Pin, which fits into the hollow bore of the reamer. This pin acts as a guide to keep the reamer perfectly coaxial with the screw shaft, preventing "skating" across the bone surface and protecting adjacent soft tissues.

• Bone-Preserving Diameter: The thin-walled construction of the reamer is designed to remove only the absolute minimum amount of bone necessary to break the screw's purchase. This is vital in hand and foot surgery where bone stock is limited.

• High Torsional Durability: Forged from vacuum-melted, hardened stainless steel, the 309.200 maintains its sharp cutting edge through dense cortical bone, ensuring a clean and efficient extraction.

Applications

• Hardware Revision: Removal of stripped or damaged 2.0mm screws from the phalanges, metacarpals, or midface.

• Broken Screw Retrieval: Extracting screw shanks that have snapped off at or below the bone surface.

• Cold-Weld Release: Freeing 2.0mm screws that have become stuck in non-locking or locking plates.

• Hand & Small Fragment Trauma: Salvaging fixation failures in 2026 where primary removal tools have failed.

Condition & Quality Assurance

• Status: NEW — Open Package.

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

• Professional Standards: With over 25 years of experience in surgical logistics, Primis Medical ensures all specialized extraction tools are stored and handled to preserve their mechanical precision.
