AI Technical Summary
Existing spinal fixation systems using pedicle screws lack flexibility for adjusting the position of spinal rods after initial fixation, limiting the ability to achieve optimal alignment and requiring additional instrumentation for repositioning.
A bone anchor extender, such as a pedicle screw tulip head extender, is designed to fit and secure into a fixed pedicle screw, allowing for variable positioning of a spinal rod by increasing the distance from the bone surface through a mounting bar and extender tulip head with adjustable dimensions.
The extender provides enhanced flexibility for repositioning spinal rods, enabling better alignment and correction of spinal deformities without disturbing the pedicle screw's initial placement, thus improving surgical outcomes in neuromuscular and revision cases.
