The Graham Field 4160 (Grafco) is a specialized orthopedic instrument designed for the efficient spreading of plaster or synthetic casts after they have been cut. This Hennig-style spreader features a heavy-duty, stainless steel construction that provides the necessary leverage to open cast shells safely and quickly. The grooved, wedge-shaped jaws are designed to fit into narrow cast saw cuts, while the ergonomic plier-style handle allows for maximum controlled force. This tool is a staple in orthopedic clinics and emergency rooms for safe cast removal procedures.
