RACHIOKYPHOSIS - Humpbacked curvature of spine; kyphosis.
RACHIOMYELITIS - Inflammation of the spinal cord.
RACHIOPARALYSIS - Paralysis of the spinal muscles.
RACHIOPATHY - Any disease of the spine.
RACHIOPLEGIA - Spinal paralysis.
RACHIOSCOLIOSIS - Lateral curvature of the spine.
RACHIOTOMY - Incision into a vertebral canal for exploration.
RACHISAGRA - Pain or gout in the spine.
RACHISCHISIS - Abnormal congenital opening of the vertebral
RACHITOMY - Surgical or anatomic opening of the vertebral
RADICULECTOMY - Excision of a rootlet or resection
of spinal nerve roots.
RADICULOPATHY - Disease of the nerve roots in or near
the spinal canal as a result of direct pressure from
a disc, or inflammation of the nerve roots due to disc
or spinal joint disease.
RADIATION ONCOLOGIST - A medical doctor who has received
advanced training in the treatment of persons receiving
x-ray treatment for an illness.
RADIATION PHYSICIST - A person having a PhD degree
who is trained in the science dealing with the properties,
changes and interactions of continuous energy.
RADICLE - A rootlet or structure resembling one, a
minute veinlet joining with others to form a vein.
RADICULAR - Relating to the radicle.
RADIOLOGIST - A medical doctor who has received specialized
training in interpreting x-rays, CTs, MRIs and performing
RADIOTHERAPY - Treatment of a lesion with radiation.
RADIUS - The lateral and shorter of the two bones of
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 - The removal of bone tissue by normal physiological
process or as part of a pathological process such as
RETROLISTHESIS - Posterior displacement of the vertebra
on the one below.
REVERSAL of CERVICAL LORDOSIS - Change in the normal
curvature of the cervical spine as seen on lateral radiograph.
This is usually a straightening of the normal lordotic
curve or an actual reversal and is most commonly caused
by muscle spasm, indicating cervical disc abnormality.
RHEUMATOID ARTHRITIS - generalized inflammatory joint
RHIZOTOMY - Division of the roots of the spinal nerves.
RISSER - For scoliosis deformity; particular attention
to fusion of facet joints and use of cast stabilization.
ROAF, KIRKALDY-WILLIS, and CATTERO - Drainage of thoracic
spinal abscess through dorsolateral approach.
ROBINSON and RILEY - An extensive anterior approach
for fusion of C-1 to C-3 or lower.
ROD - In spinal applications, a slender, metal implant
which is used to immobilize and alien the spine.
ROGER FUSION - Posterior cervical using iliac cortical
and cancellous grafts.
ROGOZINSKI - A combined anteroposterior device used
in correction of spinal deformities.
ROOT - The primary or beginning point of any part,
as of a nerve at its origin from the brainstem or spinal
ROOT SLEEVE FIBROSIS - Scar tissue surrounding a nerve
in the spinal canal or neural foramen; epineural fibrosis.
If it is within the nerve, it is called intraneural
ROUNDIND of the CRANIAL BORDER - Relationship of the
height to the width of the rounded portion of the superior

C-2; posterior bone graft with wire and parallel vertical
screw plate fixation from occiput to C-3. Posterior
pedicle screw and plate device for spinal stabilization.

where the last rib normally occurs.
