Brief Summary

Pseudarthrosis, a failure of bony fusion, is one of the most common causes of revision surgery following anterior cervical discectomy and fusion (ACDF). The interbody spacer is an important component of bony fusion in ACDF, and we aim to compare machined allograft spacers versus iliac crest allograft in a randomized controlled trial.

Outcome Measures

Primary Outcomes (4)

  • Improved participant reported outcome measures (PROMs)-1

    Investigators will ask participants to complete the Short Form-12 survey (SF-12) at 3 months, 6 months, 12 months, and 24 months following surgery

    2 years

  • Improved participant reported outcome measures (PROMs)-2

    Investigators will ask participants to complete the Visual Analog Score (VAS) for Neck and Arm, Neck Disability Index (NDI), at 3 months, 6 months, 12 months, and 24 months following surgery

    2 years

  • Improved participant reported outcome measures (PROMs)-3

    Investigators will ask participants to complete the modified Japanese Orthopaedic Association (mJOA) score) at 3 months, 6 months, 12 months, and 24 months following surgery

    2 years

  • Fusion status after surgery

    Fusion status will be assessed using Postoperative x-rays (AP, lateral, flexion, extension) which will be taken at 3 months, 6 months, 12 months, and 24 months following surgery

    2 years
