Spinal Fractures and the Impact of Frequent X-rays

Vertebral fracture and mild spondylolisthesis?

Hello! I was diagnosed with a vertebral arch fracture and mild spondylolisthesis in early January.
Since then, I have visited several clinics and have had multiple X-rays of my spine and vertebral arch.
In early March, I started shockwave therapy at one clinic and also underwent a CT scan.
Recently, I have been having weekly positioning X-rays before starting shockwave therapy, which may require 8 to 12 sessions.
Will the frequent X-rays have any impact on my body? I read that exposure below 100 millisieverts is generally considered safe, but could the cumulative exposure reach a level that might cause harm? Thank you!

Hello, the application of radiation in medicine is very extensive.
It is utilized in radiological diagnostics, radiation therapy, nuclear medicine, surgical localization in operating rooms, dental procedures, and lithotripsy in urology, among others.
When performed by qualified personnel, these procedures are safe.
The use of radiation in the medical field is increasing, and to achieve diagnostic or therapeutic goals while providing physicians with necessary information for diagnosis or treatment, it is advisable to follow the doctor's instructions regarding radiation-related examinations, as the health benefits outweigh the potential risks of radiation exposure.
If there are any concerns, it is recommended to communicate with the physician before undergoing any examinations.
Please take this into consideration, and I wish you peace and good health.

When dealing with spinal fractures and the subsequent treatment process, it is essential to understand the implications of frequent X-ray examinations. X-rays are a valuable diagnostic tool that allows healthcare providers to visualize the internal structures of the body, particularly bones. However, they do involve exposure to ionizing radiation, which can raise concerns about potential health risks, especially when multiple X-rays are taken over a short period.

In your case, you have been diagnosed with a spinal arch fracture and mild spondylolisthesis, and you are undergoing treatment that includes regular X-ray imaging. The amount of radiation exposure from X-rays is measured in millisieverts (mSv). According to the information you referenced, exposure levels below 100 mSv are generally considered safe and unlikely to cause significant health issues. For context, a single chest X-ray typically exposes a patient to about 0.1 mSv, while a lumbar spine X-ray can expose a patient to approximately 1.5 mSv.
The cumulative effect of radiation exposure is a valid concern. While the risk of developing cancer from low-dose radiation exposure is low, it is not zero. The International Commission on Radiological Protection (ICRP) suggests that the risk of cancer increases with higher cumulative doses of radiation. However, the risk associated with diagnostic imaging, particularly at doses below 100 mSv, is considered minimal. For instance, a study indicated that the additional cancer risk from a dose of 10 mSv is approximately 1 in 10,000.

In your treatment plan, if you are receiving X-rays weekly for 8 to 12 weeks, the cumulative exposure could potentially reach levels that warrant consideration. However, it is crucial to weigh the benefits of these imaging studies against the risks. The information gained from X-rays is vital for monitoring the healing process of your spinal injury and ensuring that the treatment is effective.
If you have concerns about the frequency of your X-ray examinations, it is advisable to discuss this with your healthcare provider. They can provide insights into the necessity of each X-ray and whether alternative imaging methods, such as MRI or ultrasound, could be utilized. These methods do not involve ionizing radiation and may be suitable for certain evaluations.

In summary, while frequent X-ray examinations do expose you to radiation, the levels you are likely experiencing are still within a range that is generally considered safe. The key is to maintain open communication with your healthcare team, ensuring that the diagnostic benefits of the imaging outweigh the potential risks associated with radiation exposure. Always feel empowered to ask questions about your treatment plan and the necessity of each imaging study to ensure you are comfortable with your care.

Dr. Wang Shouji reply Orthopedics
Hello: X-rays and bone density tests involve radiation exposure, while MRI does not involve any radiation at all. If the condition requires the examination, it should be performed. With modern equipment, the radiation exposure is minimal and has little impact. Thank you.
