The Synthes 388.31 4.0 mm Long Small Hexagonal Driver (13‑1/2″) is a precision orthopedic instrument designed to engage and drive 4.0 mm hex head screws in deep or difficult‑to‑access anatomical sites. The long shaft allows the surgeon to reach screws seated well within bone or through substantial soft tissues, while the 4.0 mm hex tip provides a strong interface with the screw head to minimize slippage and allow adequate torque application.

Because of its length, this driver offers a better line of approach in cases where standard shorter drivers cannot reach without retraction or enlarging exposure. The design must balance rigidity (to transmit torque without twisting or flexing) with usability; a too‑stiff driver might be hard to maneuver in tight or curved anatomical corridors, so the shaft diameter and heat‐treatment are likely chosen to maintain both stiffness and resilience.

In surgery, using this driver helps avoid the need to disassemble or remove intervening anatomy just to seat or remove a screw. However, its length also introduces potential pitfalls: torque at the handle is magnified by leverage, so care must be taken to avoid over‑torquing screws or applying excessive force that could damage screw heads or bone. Also the tip should fit exactly (no rounding), and the shaft must be clean and free of bends. Proper sterilization, inspection for tip wear, and ensuring that handle provides a secure grip (especially when wet or under gloves) are important to maintain safety and effectiveness.
