Ventral vs Dorsal Spinal Surgery on Functioning in Patients With Cervical Spondylotic Myelopathy .
This study has been identified as potentially high impact.
OE's AI-driven High Impact metric estimates the influence a paper is likely to have by integrating signals from both the journal in which it is published and the scientific content of the article itself.
Developed using state-of-the-art natural language processing, the OE High Impact model more accurately predicts a study's future citation performance than journal impact factor alone.
This enables earlier recognition of clinically meaningful research and helps readers focus on articles most likely to shape future practice.
Effect of Ventral vs Dorsal Spinal Surgery on Patient-Reported Physical Functioning in Patients With Cervical Spondylotic Myelopathy: A Randomized Clinical Trial
JAMA. 2021 Mar 9;325(10):942-951.One hundred sixty-three patients with multilevel cervical spondylotic myelopathy were randomized to receive either ventral decompression and fusion (n=63) or dorsal surgery (laminectomy with fusion or laminoplasty, n=100). The primary outcome was the change in the SF-36 physical component summary (PCS) score at 1 year. Secondary outcomes included changes in the modified Japanese Orthopaedic Association (mJOA) score, Neck Disability Index (NDI), EuroQol-5D (EQ-5D), complication rates, work status, sagittal alignment, and healthcare resource use, assessed up to 2 years. Overall, the results revealed no significant difference in the 1-year improvement in SF-36 PCS scores between the ventral (5.9 points) and dorsal (6.2 points) groups. Complication rates were significantly higher in the ventral group. The study suggests both approaches lead to meaningful functional improvements, but ventral surgery carries a higher risk of complications.
