Synthes 387.276 4.0mm Cortex Expansion Handle – 10-1/2" Orthopedic Surgical Instrument

The Synthes 387.276 Cortex Expansion Handle is a precision surgical instrument engineered for high-stakes orthopedic procedures involving cortical bone. Specifically designed for use with 4.0mm cortical drill bits, taps, and reamers, this handle serves as the critical mechanical interface between the surgeon’s manual force and the cutting instrument. It is primarily used to prepare, enlarge, or refine holes in dense bone to ensure a perfect fit for cortical screws and implants.

Measuring 10-1/2 inches (26.6 cm) in length, the 387.276 provides the ideal balance of reach and leverage. The extended shaft allows for deep-access control within the surgical exposure, while the handle's ergonomic design ensures a stable, "no-wobble" grip. This stability is vital to prevent mis-drilling or weakening of bone edges during cortical expansion and reaming tasks.
