Reading

Practice pronunciation of medical terms by reading the following medical report aloud.

Degenerative, Intervertebral Disk Disease

Anteroposterior and lateral views of the lumbar spine and an AP view of the sacrum show a displacement of L5 on
S1. The L5–S1 intervertebral disk space contains a slight shadow of decreased density. There is now slight narrowing
of the L3–L4 and L4–L5. Bilateral laminectomies appear to have been done at L5–S1. Slight hypertrophic lipping of
the upper lumbar vertebral bodies is now seen, as is slight lipping of the upper margin of the body of L4. The sacroiliac
joint spaces are well preserved. Lateral views of the lumbosacral spine taken with the spine in flexion and extension
show slight motion at all of the lumbar and lumbosacral levels.

IMPRESSION: 1. Degenerative, intervertebral disk disease at L5–S1, now also accompanied by slight narrowing of
the L3–L4 and L4–L5.

2. Slight motion at all of the lumbar and lumbosacral levels.
