  • Alternative modes of treatment other than the traditional standard of care
  • Potential benefit of preserving the motion of the cervical and lumbar spine
  • Potential improvement of quality of life


Dr. Cheng is the Principal Investigator on the following clinical trials:

  • Spinal Motion - Kineflex, single-level lumbar artificial disc replacement
  • Medtronic - Prestige, two-level cervical artifical disc replacement
  • Archus Orthopedics - Total Facet Arthroplasty System, facet replacement

All clinical trials must be approved through the Loma Linda Institutional Review Board before the beginning of patient enrollment. All studies are then conducted by the protocol guidelines of the sponsor and the Food and Drug Administration.

Patients are pre-screened to determine whether or not they meet inclusion/exclusion criteria set for each individual study.
