Synthes 421.335 1.3mm titanium Y-plate 3-hole head 8-hole shaft 32mm orthopedic hardware

Synthes 1.3mm Titanium Y-Plate | 3-Hole Head | 8-Hole Shaft | 421.335

The Synthes 421.335 is an ultra-low-profile internal fixation implant engineered for the stabilization of complex fractures in the most delicate bony structures. Featuring a Y-shaped geometry, this plate is specifically designed to provide multi-directional anchorage in the expanded metaphyseal or articular regions of micro-bones.

At a 32mm length with a 3-hole head and an 8-hole shaft, the 421.335 provides the extensive reach and high-density screw fixation required for comminuted fractures where a standard straight plate would lack sufficient points of contact. Constructed from implant-grade Titanium, it offers the highest level of biocompatibility and non-magnetic properties for post-operative imaging.

Technical & Clinical Advantages

• Triangulated Head Stability: The 3-hole "Y" head allows for divergent screw placement. This creates a "triangulated" construct that is significantly more resistant to rotational and pull-out forces than a single-line screw array, making it ideal for small articular fragments.

• Titanium Biocompatibility: Commercially pure titanium promotes superior osseointegration and minimizes the risk of inflammatory soft-tissue response. Its lightweight nature is critical in micro-fixation where excess hardware mass can impede functional recovery.

• Ultra-Low Profile Design: Engineered for anatomical regions with nearly zero soft-tissue coverage (such as the distal phalanges or midface), the plate is designed to sit flush against the bone to prevent hardware palpability and tendon adhesions.

• 8-Hole Lever Arm: The extended 8-hole shaft provides a substantial lever arm to bridge comminuted zones or to provide stable neutralization across an osteotomy site, distributing mechanical loads over a larger surface area of healthy bone.

• Malleable Contouring: While providing rigid fixation, the titanium alloy is designed to be intraoperatively contoured with micro-bending irons, allowing the surgeon to match the complex three-dimensional curves of the midface or hand anatomy.

Applications

• Craniomaxillofacial (CMF) Surgery: Stabilization of midface, orbital rim, and frontal sinus fractures where multi-directional support is required.

• Hand & Finger Surgery: Fixation of comminuted phalangeal head fractures or distal metacarpal reconstructions.

• Reconstructive Micro-Surgery: Anchoring small bone grafts or stabilizing complex osteotomies in the forefoot or hand.

• Neuro-Reconstruction: Securement of delicate bone flaps in pediatric or specialized adult cases.
