Factors affecting the surgical results of expansive laminoplasty for cervical spondylotic myelopathy

This study investigates factors influencing the success of a surgery called expansive laminoplasty for patients with cervical spondylotic myelopathy, a condition where the spinal cord in the neck is compressed. The study divided patients into 'good' and 'fair' recovery groups based on how well they recovered after surgery, and then looked for differences in pre-operative measurements and conditions. The goal was to identify which pre-operative factors could predict how well a patient would respond to the surgery, helping doctors make better decisions about treatment.

• 1
  Patients with better pre-operative JOA scores, greater compression ratios, and larger Pavlov ratios had better surgical outcomes.
• 2
  The presence of high signal intensity on MRI was not a reliable predictor of surgical success.
• 3
  Duration of symptoms affected surgical outcomes only in patients with more severe pre-operative symptoms (JOA score less than 9).
