Definition

As part of an infiltration, one or more substances are injected into a region of the body, e.g. in tendons, muscles, joints or near the spine. The targeted application to painful areas results in rapid and effective pain relief. Another advantage of local application is the lack of systemic side effects. There are various substances that can be used for infiltration and are selected individually depending on the clinical picture. Local anesthetics are most commonly used in combination with cortisone. Other substances that can be used are hyaluronic acid, autologous blood (PRP) and Traumeel®.

Mode of action

Depending on the substance used, infiltrations have the following effects on the body:

  • Local anesthetics (local anesthetics): Relief of pain
  • Cortisone: inhibition of inflammatory processes
  • Hyaluronic acid: improves the gliding ability in the joint
  • Autologous blood (PRP)Stimulation of self-healing processes in the body
  • Traumeel®: Relief of pain, inhibition of inflammatory processes

Local anesthetics quickly lead to pain relief. In combination with cortisone, they also inhibit inflammation. The typical dreaded side effects of cortisone (weight gain, high blood pressure, increased blood sugar) are not to be expected due to the local and short-term application.

Hyaluronic acid is one of the main components of connective tissue and synovial fluid. It serves as an artificial synovial fluid and thus improves the gliding ability of the joint.

Another substance is autologous blood, which is intended to stimulate self-healing processes in the body. Autologous blood (PRP) is often used in combination with hyaluronic acid for joint infiltrations.

Traumeel® is a homeopathic remedy that contains plant-based active ingredients such as St. John's wort, camomile and marigold.

Areas of application

Infiltrations are used for a wide range of orthopaedic conditions. These include acute and chronic pain in particular, where conservative therapy has not yet produced satisfactory results. Infiltrations are never used as the sole pain therapy, but only in combination with other therapeutic measures.

Infiltrations are used for the following orthopaedic diseases, among others:

Facet infiltration:

In the case of facet joint arthrosis, joint wear of the small intervertebral joints, a facet block can contribute to significant pain relief. This involves pain treatment of the intervertebral joints (facet joints) and their immediate surroundings. After local anesthesia, medication is injected precisely into the facet joints under the control of an imaging procedure such as ultrasound or X-ray. As facet joints at different levels of the spine are often affected, several injections may be necessary.

ISG infiltration:

In cases of persistent pain in the sacroiliac joint and unsuccessful pain and physiotherapy, local infiltration of pain and anti-inflammatory preparations near the joint or directly into the joint can improve the symptoms.

Periradicular therapy:

In particularly severe cases of a slipped disc, periradicular therapy can be carried out, in which painkillers are injected close to the irritated nerve root.

Treatment process

In the vast majority of cases, infiltrations are performed on an outpatient basis and without anesthesia. A session lasts between 20 and 40 minutes, depending on the clinical picture, including preparation and follow-up. As a rule, two to four sessions are necessary to achieve long-term pain relief.

After thorough disinfection and a subsequent local anaesthetic, the infiltration can begin. The needles are applied precisely using computer tomography, an X-ray or ultrasound. Sterile disposable instruments are used to avoid infection. Sterility is particularly important when infiltrating joints, as the immune system is very weak in these areas.

With regard to the substances used, it can be stated that local anesthetics with or without cortisone are used in particular for pain and irritation. Hyaluronic acid is primarily used in the context of osteoarthritis and Traumeel® is mainly used for painful conditions of tendons or muscles. The selected substance can be injected into the affected area of the body using thin needles. After the infiltration, you should remain in our practice for about half an hour for observation.

Side effects

Possible side effects and risks may include

  • Pain at the puncture site
  • Bruising
  • Rarely: Infections

Normally, infiltration is a safe procedure with few side effects. If pain occurs at the injection site after the treatment, painkillers from the group of non-steroidal anti-inflammatory drugs (NSAIDs) can be taken. In rare cases, infections may occur.

FAQs

The advantages and disadvantages of infiltration must be carefully weighed up for people with blood clotting disorders or people taking blood thinners , as there is a risk of bleeding. Infiltration should never be carried out in the case of allergies to any of the substances used. Inflammation in the region to be treated is also a criterion for exclusion.

This depends on both the subjective sensation of pain and the area of the body to be treated. As a rule, infiltration treatment is only slightly painful, as a local anesthetic is administered before the actual treatment. Nevertheless, patients may experience a slight to strong pulling sensation when the needle is inserted and the substance is injected. Pain may also occur after the treatment, which can be treated with painkillers from the group of non-steroidal anti-inflammatory drugs (NSAIDs) .

You will come to our practice on the day of your treatment. You do not need to take any special precautions beforehand. The affected body region will be disinfected and anaesthetized. Depending on the area to be treated, the position of the needle is checked during infiltration using computer tomography, an X-ray or an ultrasound image. The thin needle is positioned and the substance, usually a local anesthetic, is injected. After the treatment, you will remain in our practice for around 30 minutes, after which you will be allowed to go home. If necessary, further sessions will take place at weekly intervals.

After spinal infiltrations, you should not drive or operate machinery for several hours afterwards. Infiltrations in other parts of the body do not usually require any special precautions. If you feel severe pain, rest the area in question for a few days and take painkillers from the group of non-steroidal anti-inflammatory drugs (NSAIDs) .

Local anaesthetics quickly take effect in the body, so that an improvement in symptoms can be expected immediately after infiltration. When using other substances such as autologous blood or hyaluronic acid, on the other hand, it can take several weeks before there is a noticeable improvement in symptoms.

Statutory health insurance companies cover the costs of infiltration treatment depending on the substance used and the area of the body affected. It is best to call your health insurance company and ask.
