摘要：
Provided are rod coupler devices, systems, kits and methods, which include at least one saddle having a concave configuration that either abuts a bone fastener and/or a locking cap and is shaped so as to contact the rod in two or more lines of contact, which reduces pressure on the rod, and therefore permits use of a rod having various materials, such as PEEK, without significant deformation of the rod. Also provided is the saddle itself and integrated locking caps that include a saddle, the locking cap and a set screw. Also provided are elongate rods having advantageous shapes, configurations, and/or compositions for rod coupler devices, systems and methods. Further provided are screw and cap devices and systems that themselves include a concave configuration so as to contact a rod in two or more lines of contact, which reduces pressure on the rod.
