The Bryan Cervical Disc prosthesis effectively preserves spinal motion for degenerative disc disease. Major complications were infrequent, though some patients experienced pain or kyphosis post-surgery.

Area of Science:

  • Neurosurgery
  • Orthopedic Surgery
  • Spinal Surgery

Background:

  • Spinal arthroplasty is an emerging treatment for degenerative cervical disc disease.
  • This technique offers potential advantages over spinal fusion but introduces new surgical challenges and complications.

Purpose of the Study:

  • To assess the incidence and types of perioperative complications associated with the Bryan Cervical Disc prosthesis.
  • To evaluate the early clinical and radiographic outcomes of Bryan prosthesis-based cervical arthroplasty.

Main Methods:

  • Prospective data collection on operative details, complications, and outcomes in 74 patients undergoing one- to three-level Bryan arthroplasty.
  • Ninety-six Bryan prostheses were implanted.
  • Complication rates and outcomes were analyzed at two tertiary care centers.

Main Results:

  • The overall perioperative complication rate was 6.2% per treated level.
  • Complications included retropharyngeal hematoma, neurological worsening, prosthesis migration, and segmental kyphosis.
  • Motion was preserved in 94 of 96 prostheses; however, 25% reported late neck/shoulder pain.

Conclusions:

  • The Bryan prosthesis demonstrates effectiveness in maintaining spinal motion.
  • Major perioperative and device-related complications were infrequent in this early series.
