- RADICULAR
- Relating to the radicle.
- RADIOLOGIST
- A medical doctor who has received specialized training in interpreting x-rays, CTs, MRIs and performing angiography.

- Treatment of a lesion with radiation.
- RADIUS
- The lateral and shorter of the two bones of the foreman.
- RECOMBINANT HUMAN PROTEINS
- proteins developed by isolating a human protein and using recombinant DNA technology to produce genetically engineered proteins that act like natural proteins.
- REFERRED PAIN
- Sclerotomic in distribution and felt distant from its origin (e.g., bursitis in the shoulder produces pain in the lateral arm, and sciatic-like leg pain can be referred from the lower-back area).
- REFLEX
- An involuntary reaction in response to a stimulus applied to the periphery and transmitted to the nervous centers in the brain or spinal cord.
- RESECTION
- The surgical removal of part of a structure, such as bone.
- RESORPTION
