Article Synopsis
- Most total disc replacements result in excessive mobility and can lead to chronic back pain due to their inability to mimic natural spinal movement.
- In a study involving cadaveric lumbosacral spines, researchers analyzed the movement after disc removal and subsequent prosthesis implantation, comparing flexion, extension, lateral bending, and rotation.
- The new ADDISC total disc replacement showed promise in mimicking natural disc kinematics but was unable to fully restore normal motion because the ligaments around the disc became destabilized during surgery, indicating a need for improved techniques in the future.
Study Design: Biomechanical study in cadaveric specimens.
Background: The commercially available lumbar disc prostheses do not reproduce the intact disc's Instantaneous centre of Rotation (ICR), thus inducing an overload on adjacent anatomical structures, promoting secondary degeneration.
Aim: To examine biomechanical testing of cadaveric lumbar spine specimens in order to evaluate and define the ICR of intact lumbar discs.
