A bone growth stimulator is a medical device designed to encourage the body’s natural healing process in bones that have difficulty mending on their own. These devices are often recommended when a fracture is not healing as expected, a condition known as a nonunion or delayed union, or following certain surgeries like spinal fusions. Many individuals wonder if using such a device causes pain. This article explores how bone growth stimulators function and addresses potential sensations or discomfort associated with their use.
How Bone Growth Stimulators Work
The human body naturally generates mild electric fields during bone growth and healing. Bone growth stimulators mimic these natural processes by delivering specific forms of energy, such as low-level pulsed electromagnetic fields or pulsed ultrasonic energy, to the injury site. This energy stimulates bone-forming cells, enhances tissue repair, and promotes faster healing and increased bone density.
External bone growth stimulators are portable units worn outside the body, often over clothing or a cast, secured with straps. These can be electrical stimulators, using coils or electrodes to create a low-level electrical field, or ultrasonic devices, transmitting sound waves through a coupling gel. Internal stimulators are surgically implanted directly at the fracture site. Both types provide energy that supports the body’s ability to repair and regenerate bone tissue.
Addressing Potential Pain and Discomfort
Significant pain is not a common side effect of using bone growth stimulators. Many patients report feeling nothing at the treatment site from the electrical or ultrasound waves emitted by the device, as the current is often imperceptible and does not cause discomfort. However, some individuals might experience mild, temporary sensations or discomfort.
These sensations can include tingling at the application site, localized skin irritation (such as redness or a rash) where the device’s electrodes or pads make contact, or minor soreness. This discomfort is usually related to the device’s placement or the body’s initial adjustment to the therapy, rather than the bone healing process itself. It is typically manageable and tends to subside as treatment continues.
Managing Discomfort and Other Side Effects
For mild discomfort, ensure the bone growth stimulator is properly positioned and secured according to manufacturer’s instructions. Regularly inspect the skin around the application site for any signs of irritation and practice good skin hygiene to help prevent issues like rashes or soreness. If skin irritation occurs, a healthcare provider might recommend topical creams, possibly including steroid creams.
While most discomfort is mild, over-the-counter pain relievers can manage minor aches, but only with healthcare provider approval. Some devices, particularly for spinal fusion, list potential adverse effects such as increased pain, numbness, tingling, or headaches. If these effects are directly related to the device, they should cease upon discontinuation. Always discuss any persistent or new sensations with your prescribing doctor.
When to Seek Medical Attention
While mild discomfort typically resolves, certain symptoms warrant immediate medical attention. Contact a healthcare provider promptly if severe or worsening pain occurs, especially if it is not at the application site or is more intense than expected. Signs of infection at the application site, such as fever, pus drainage, or spreading redness and swelling, also require urgent evaluation.
Other concerning symptoms include skin breakdown at the site, persistent numbness or tingling, or device malfunction. Any symptoms that raise concern or interfere significantly with daily life should lead to a consultation with a healthcare professional to ensure patient safety and effective treatment.
