Zimmer 2255-32-37 M/DN Intramedullary Fixation Tibial/Humeral Drill 3.7mm

Zimmer M/DN Intramedullary Drill | 3.7mm Diameter | 10.5" Length | 2255-32-37 | NEW

The Zimmer 2255-32-37 is an essential high-performance power accessory designed for the precise preparation of interlocking screw holes in long-bone fixation. As a core component of the Zimmer M/DN (Multi-Directional Nail) System, this 3.7mm drill bit is specifically engineered to create the transverse pathways required for distal and proximal locking screws in the tibia and humerus.

Featuring an extended 10-1/2 inch (26.7 cm) overall length, this bit is designed to clear bulky soft-tissue envelopes and navigate the deep surgical corridors often encountered in intramedullary nailing. The extra-long shaft ensures that the surgical power driver remains well outside the primary operative site, providing the surgeon with an unobstructed line of sight and superior ergonomic control during high-torque drilling.

Key Specifications

• Manufacturer: Zimmer Biomet

• Series: M/DN™ Intramedullary Fixation System

• Model / REF: 2255-32-37

Technical & Clinical Advantages

• 10.5-Inch Deep-Access Reach: The extended profile is critical for "over-the-top" drilling in humeral and tibial nailing, allowing the bit to pass through soft-tissue protectors and targeting guides while maintaining a perpendicular trajectory to the nail.

• High-Efficiency Flute Geometry: Precision-machined flutes facilitate rapid bone chip evacuation. This reduces friction-induced heat during the penetration of dense cortical bone, significantly lowering the risk of thermal necrosis and supporting faster osseointegration.

• M/DN System Compatibility: This bit is factory-calibrated to match the tolerances of Zimmer M/DN nails, ensuring that the resulting 3.7mm hole perfectly accommodates the system's corresponding locking screws for a stable, rigid construct.

• Standard AO Quick-Connect: The universal QC shank ensures a secure, "no-play" attachment to all major surgical power systems and manual T-handles, facilitating rapid intraoperative instrument transitions.

• Pristine Factory Condition: As a New-in-Box item, the cutting edges are factory-perfect, ensuring maximum cutting efficiency and procedural safety for the first use.

Applications

• Tibial Nailing: Transverse drilling for proximal or distal interlocking screws.

• Humeral Nailing: Precise hole preparation in the humerus where neurovascular proximity requires absolute drill stability.

• IM Fixation: Any intramedullary procedure requiring a high-tensile 3.7mm drill with extended reach.

Condition & Quality Assurance

• Status: New – In Original Manufacturer's Packaging.

• Integrity: This instrument is in pristine, unused condition. It has remained sealed and untampered with since leaving the Zimmer facility (may have been opened briefly for photographic documentation only).
