4 mm Ligament Washer
The 4 mm Ligament Washer, also known as a 4.0 mm Spiked Washer, is an orthopedic implant component designed for soft-tissue and ligament fixation to bone. It is commonly used with compatible low-profile cancellous screws in knee reconstruction procedures. The underside spikes are designed to engage the bone and help resist washer movement during fixation.
Depending on the manufacturer and product specification, 4 mm spiked washers are available in titanium or titanium alloy, with product designs varying in spike configuration and dimensions.
