The Synthes 387.276 Cortex Expansion Handle is a surgical instrument used in orthopedic procedures, particularly when working with cortex screws or cortical bone. “Cortex expansion” suggests its use in either preparing holes in cortical bone (for screws, pins, or other implants) or expanding existing holes to fit a specified diameter. With its 4.0 mm specification, it is likely matched with 4.0 mm cortical drill bits, taps, or other instruments within the Synthes system that require a compatible handle or drive interface.

At 10 ½ inches (≈ 26.6 cm) in length, the instrument is long enough to give the surgeon a solid grip and leverage, permitting control deep in surgical exposure, yet short enough to allow maneuverability in a typical operating field. The handle may be designed to connect with other attachments or shafts (e.g. extension bars, bits) in the Synthes system, ensuring that the 4.0 mm component is securely held and driven. The construction material is not explicitly listed in the available sources, but Synthes instruments are generally made of surgical-grade stainless steel or similar high-strength biocompatible metals, capable of sterilization and repeated use.

In practice, the expansion handle helps improve precision and efficiency in operations involving cortical bone when holes must be enlarged, reamed, or otherwise prepared to accept implants (such as screws or bolts). It serves as a mechanical interface between the surgeon’s driving force (manual or powered) and the cortical instrument (drill, tap, reamer). Because accurate alignment, minimal wobble, and secure attachment are important (to avoid mis-drilling, weakening of bone edges, or tool slippage), an instrument like this is critical. Also, by offering a standard handle size and drive compatibility, it integrates into broader instrument sets, helping maintain consistency and reducing the risk of mixing incompatible instruments.
