Redo lumbar spine kyphoplasty
A redo kyphoplasty is a viable option after having one performed, especially if the initial kyphoplasty did not inject enough cement to stabilize the vertebral body which is what we suspect in this case. Therefore we filled her vertebral body with an additional 8 mL of cement which resolved her pain.
Osteoporosis is a disease in which the bones lose density making someone more prone to fractures. According to the U.S. National Library of Medicine, "as a result of osteoporosis about half of all women over 50 will experience a fracture of the hip, wrist, or vertebra."
This patient was a female 75-year-old so she already had a predisposition to having a fracture like this occur. According to the Hartford HealthCare Medical Group, osteoporosis affects about 30 million Americans and 700,000 individuals experience vertebral fractures each year. Although the levels of severity can differ and are treated differently, about 260,000 of these cases are vertebral compression fractures. However, a lot of these vertebral compression fractures are not treated, misdiagnosed or never diagnosed.
After a patient has already received a kyphoplasty, there is an 8% chance of having a cement leakage. There is a <1% chance of having a repeat fracture in the previously treated vertebra and a 9% chance in the adjacent vertebrae. There is a 0.17% chance of having a PCE (pulmonary cement embolism). Spinal stenosis resulting in compression of the spinal cord occurred in 0.16% of the cases 2.
Vertebral compression fractures (VCF) are most commonly caused by osteoporosis. In patients with osteoporosis, the forces encountered in daily life are enough to cause fractures. They also occur in patients on "long-term steroid therapy" or in patients suffering from cancers that have metastasized to the spine. These fractures occur when the vertebral cortex collapses which reduces the overall structure of the vertebra causing excruciating pain. About an equal number of fractures occur acutely, as occur chronically.
