Vertebral fracture treated with kyphoplasty: case
review
The following set of images outlines one patient's
experience with the use of kyphoplasty to treat a vertebral
compression fracture.
Initial diagnosis
After this 78 year-old man slipped
and fell while at home, he complained of mid-back pain.
A lateral (side view) x-ray was taken, which showed
a compression fracture of the L1 vertebra (see Figure
1).
He was initially treated with pain medication and a
removable back brace.
Continued pain
Six weeks later, the patient was experiencing
continued pain that limited his ability to do everyday
activities. A new x-ray was taken that showed increased
collapse of the front of the L1 vertebra (see Figure
2),
creating wedging of the vertebra and causing the
patient to stand leaning forward.
Surgical planning
To help plan the treatment, it was
important to also view the back of the vertebra to
see if there was any damage. Cement fixation
via vertebroplasty or kyphoplasty is considerably less
safe in cases where the back of the vertebral body
is also fractured, because of the increase in the chance
of leakage of cement into the spinal nerve canal. Therefore,
a CT scan image of the fractured L1 vertebra was taken
(see Figure
3),
which in this case showed no such breaks in the back
of the vertebral body.
It was decided to proceed with kyphoplasty, with the
goal of alleviating the patient's pain and restoring
the height of the vertebra (to reduce the wedge shape)
so that the patient would be able to stand upright.
Postoperative images
Following the kyphoplasty procedure,
x-ray images of the L1 vertebra were taken. The
lateral (side view) x-ray showed restoration of the
height of the front of the L1 vertebra to its original
fracture height before the additional collapse (see Figure
4).
Likewise, the anteroposterior (front view) x-ray following
the kyphoplasty also shows restoration of the L1 vertebra
(see Figure
5).
The whitened areas shown in the x-rays are the
cement that was injected into the bone after elevation
of the collapsed vertebra with the inflatable balloon.
Following the procedure, the patient was able to stand
upright and reported a considerable reduction in his
level of pain, and he was able to return to his normal
activities.
