To combat degenerative lumbar diseases, lumbar spine fusion is recognized as an effective surgical procedure. During Lumbar fusion, solid arthrodesis, immobilization of the unstable segment and degenerated intervertebral disk area can be achieved effectively. Bilateral pedicle screw fixation is regarded as a standard surgical method for degenerative lumbar diseases. However, there are certain shortcomings associated with rigid fixation .
Rigid internal fixation had the potential to accelerate the degeneration of adjacent lumbar segments and cause device-related osteoporosis and was associated with greater blood loss, longer operative time, and greater costs. With unilateral pedicle screw fixation, studies have shown that it reduces the effects of stress shielding on the fixed vertebrae and avoid adjacent intervertebral disc degeneration. It is also enough to maintain the stability of…
