Shortwave Therapy and Metal Implants: Safety Concerns in Rehabilitation

Shortwave vs. Steel Pins

Hello, doctor.
I recently visited a small clinic for knee rehabilitation where they used shortwave and ultrasound therapy.
I just looked up the contraindications for shortwave therapy and found that it is best to avoid proximity to metal objects.
I remembered that I have a steel pin in my shoulder from a previous surgery, but the therapist did not inform me about this.
I would like to know if this could potentially raise the temperature of the steel pin and cause damage to the surrounding tissues.
Or does it not matter since the treatment area is different? Additionally, how far should the metal object (my shoulder) be from the device during therapy to be safe? Or is shortwave therapy not suitable for me at all?

Rehabilitation should still be possible, but please inform us of your condition so we can consider alternative treatments.

More Info

Shortwave therapy, also known as diathermy, is a form of electromagnetic therapy that uses high-frequency electromagnetic waves to generate heat in body tissues. This technique is often employed in rehabilitation settings to promote healing, reduce pain, and improve circulation. However, when it comes to patients with metal implants, such as screws or plates used in orthopedic surgeries, there are important safety considerations to keep in mind.

First and foremost, it is crucial to understand that shortwave therapy can indeed cause heating of metal implants. The metal can absorb the electromagnetic energy, leading to an increase in temperature. This localized heating can potentially result in damage to the surrounding tissues, including burns or thermal injury, especially if the treatment is applied for an extended period or at high intensity. Therefore, it is essential to inform your physical therapist or rehabilitation specialist about any metal implants you have before undergoing such treatments.

In your case, since you have metal screws in your shoulder from a previous surgery, it is advisable to exercise caution. While the distance between the treatment area and the metal implant can influence the risk of heating, it is generally recommended to avoid applying shortwave therapy directly over or near the area of the metal implant. The specific distance that is considered safe can vary depending on the type of equipment used and the intensity of the treatment, but a common guideline is to maintain at least a few centimeters of distance from the metal implant.

If you are concerned about the safety of shortwave therapy in your rehabilitation, it would be prudent to discuss this with your healthcare provider or physical therapist. They can evaluate your specific situation, including the type and location of your metal implant, and determine whether shortwave therapy is appropriate for you. They may also suggest alternative rehabilitation modalities that do not pose the same risks, such as ultrasound therapy, electrical stimulation, or manual therapy techniques.

In summary, while shortwave therapy can be beneficial for rehabilitation, it is essential to consider the presence of metal implants. The potential for increased temperature and subsequent tissue damage necessitates caution. Always communicate openly with your healthcare providers about your medical history and any concerns you may have regarding treatment options. Your safety and well-being should always be the top priority in any rehabilitation program.
