Polyaxial screw with improved locking |
| abstract |
The multiaxial pedicle screw assembly includes a recess on the receiver that engages the convex surface on the head of the screw to form a ball joint. The radius of at least a portion of the concave surface is less than the radius of the convex portions to join, providing an interference fit. |
