Apatient has a slipped (herniated) disk. what treatment will alleviate his condition? a) percutaneous discectomy b) joint surgery c) replacement surgery d) vertebroplasty

A) Percutaneous discectomy

Explanation:

Percutaneous discectomy is the most common type of surgery when it comes to removing damaged piece of herniated disk in one's spine. Percutaneous means ''through the skin'' and s very little cut is made in order to perform this procedure. This disk can irritate or compress nerves. It is the most effective method for treating pain that occurs down one's arms or legs. This procedure isn't that helpful when it comes to treating bad back pain or neck pain, in this case, it's better to try with physical therapy first. There are many kinds of PD procedures, but all of them use tiny instruments that doctors insert between vertebrae and into the middle of the disc. Most of the doctors use local anesthesia for this procedure.

a, b, c - sides of a triangle

a + b > c

a + c > b

b + c > a

we have a = 5m and b = 11m. substitute:

5 + 11 > c

16 > c → c < 16

5 + c > 11         subtract 5 from both sides

c > 6

11 + c > 5         subtract 11 from both sides

c > -6

c < 16 and c > 6 and c > -6

thereofre your answer is 6m < c < 16m
