Effects of two posterior procedures for treatment of cervical hyperextension injury with multilevel spinal stenosis: A retrospective study

This study compares two surgical techniques for treating cervical hyperextension injuries in patients who also have spinal stenosis. These injuries often affect older adults and require surgery to address spinal compression and stability. The first technique involves laminoplasty with unilateral pedicle screw fixation, while the second uses laminectomy with bilateral lateral mass screw fixation. The study assesses which approach leads to better patient outcomes. Researchers collected data on surgical time, hospital stay, blood loss, complications, and neurological function using the ASIA impairment scale. They also measured cervical lordosis before and after surgery to see if the procedures affected spinal alignment.

• 1
  Both surgical procedures led to significant improvements in postoperative AISA scores compared to preoperative scores, indicating enhanced neurological function after surgery.
• 2
  The laminoplasty group experienced significantly less intraoperative blood loss compared to the laminectomy group, suggesting that laminoplasty may be a less invasive option in terms of blood loss.
• 3
  There was no significant difference in overall surgical complications or changes in cervical lordosis between the two groups, indicating comparable safety and maintenance of spinal alignment.
