Frequently Asked Questions
What is LigaZip P used for?
LigaZip P is a PEEK interference screw designed for robust graft fixation in ligament reconstruction procedures. Its taper tip with self-starting threads facilitates insertion without requiring a tap, while the dual-start buttress threads are designed to provide strong fixation and minimize graft damage during implantation.
What are the advantages of PEEK interference screws?
PEEK (polyether ether ketone) interference screws offer biocompatibility, high mechanical strength, non-bioresorbability, and MRI compatibility. Unlike metallic screws, PEEK is radiolucent and produces minimal MRI artifact, which can facilitate postoperative imaging and assessment of graft incorporation.
Is LigaZip P compatible with MRI scans?
LigaZip P is made from PEEK, a non-metallic material that is generally compatible with MRI and does not produce the same metal-related imaging artifacts associated with metallic interference screws. However, the MR safety status and conditions for the specific LigaZip P device should be confirmed from its current product labeling or instructions for use before an MRI examination.
What are the key features of LigaZip P?
LigaZip P features a PEEK construction, taper tip with self-starting threads, blunt buttress-profile dual-start threads, and an anti-slip hexalobular socket. These features are designed to facilitate easy insertion, provide strong pullout resistance, minimize graft amputation, and ensure positive driver engagement during implantation.
