infiltration du rachis lombaire à Paris

Lumbar spine pain?

Du point de vue anatomique, le rachis (colonne vertébrale) est une partie du squelette qui relie la tête et le bassin.  C’est un empilement d’os articulés appelés vertèbres. Le rachis est complexe vu qu’il est composé de plusieurs éléments : vertèbres, disques (un disque vertébral est une structure située entre deux vertèbres consécutives et qui joue un rôle d’amortisseur lors des mouvements), cartilages, ligaments, muscles et nerfs. Ajoutons que la moelle épinière, qui est une structure du système nerveux central, passe à l’intérieur de la colonne vertébrale. Du point de vue fonctionnel, le rachis supporte le poids du corps et permet de pivoter le membre supérieur du corps.

The spine is an anatomically and functionally rich region, prone to both minor and serious damage.

As a result, spinal pain is a frequent reason for medical consultations. This pain can have several etiologies. Damage to one of the joint's structures (vertebrae, discs, ligaments, muscles) can cause pain.

Qu’est-ce qu’une infiltration du rachis ?

Aspinal infiltration involves injecting a corticosteroid-based medication into the painful spinal column.

L’infiltration a pour objectif de réduire la douleur temporairement, mais ne traitera pas de façon définitive une inflammation vertébrale ou ne résorbera pas une hernie discale.

No special preparation is required for spinal infiltration.

How does this therapeutic technique work ?

Our radiologists are experts in this field.

The procedure takes 10 minutes.

You will lie on your back. This procedure sometimes requires a local anaesthetic. Infiltration can be carried out under radiological control, to reach the precise area to be infiltrated. The radiologist locates the puncture point, disinfects the area of skin, then injects the medication using a needle.

Il s’agit d’un geste très simple et pratiquement indolore. Ce geste médical est rarement douloureux, semblable à une simple prise de sang.

After infiltration, we recommend that you avoid any physical activity for 2-3 days. This period of rest helps to improve your symptoms.

How does spinal pain manifest itself ?

On peut avoir une douleur au repos (sans activité physique) ou une douleur après un effort physique qui fait intervenir le dos. De plus, cette douleur peut rester localisée au niveau de votre dos comme elle peut irradier (migrer) vers d’autres régions de votre corps. À la douleur peut s’associer d’autres symptômes comme, par exemple, une limitation de la mobilité du rachis.

This can help with lower back pain :

  1. Limit your physical exercise.
  2. Always try to maintain good posture. It helps!
  3. Votre médecin peut vous prescrire un traitement médical anti-inflammatoire et/ou antalgique.

What types of spinal infiltration are there?

Several types of infiltration are available. Your choice will be guided by the origin of your pain.

There are several infiltration zones:

  1. Epidural : An epidural is a form of regional anesthesia in which a needle is introduced into the epidural region (the area above a special membrane called the dura that covers the spinal cord and nerves in the spinal column). 
  2. Posterior joint
  3. Intradiscal: the injection is made inside the intervertebral disc.
  4. Forminal

What causes lower back pain ?

Back pain can have many causes. Here are the most common causes of back pain:

1 - Trauma : A fall, an accident... can cause a fracture of the vertebrae in the back, or a dislocation of the intervertebral discs. The result is severe pain and limited joint mobility.

2 - Osteoarthritis of the spine : It's a joint disease characterized by chronic wear and tear of the vertebrae. It generally occurs as a result of the destruction of intervertebral discs with age. Normally, the disc serves to improve contact between the vertebrae. When the disc is lost, contact between the two bones of the joint is no longer effective, resulting in significant pain. You are more likely to develop osteoarthritis if you : 

  • Are over 50 years of age; 

  • Are overweight;

  • Are going through menopause; 

  • If a family member has already developed the disease; 

  • Already have a basic skeletal abnormality; 

  • Have a metabolic disease already diagnosed by your doctor.

3 - Herniated disc : A herniated disc occurs when the peripheral part of the disc ruptures and the central part protrudes. Aging, injury and excess weight can lead to herniated discs.

4 - Spondylodiscitis : This is an infection of the intervertebral disc. It is frequently accompanied by fever.

5 - Neurological pain caused by inflammation or compression of nerves.

Other causes: cancer, inflammatory diseases...

What you need to know about lumbar spine infiltration.

Infiltration of the lumbar spine is a procedure commonly used to relieve back pain, including low back pain, sciatica and nerve pain. This technique involves injecting medication directly into the affected area, usually around the lumbar vertebrae, to reduce inflammation and relieve pain. Infiltrations can include anti-inflammatories, which work by reducing inflammation of the surrounding nerves and muscles, as well as local anesthetics for immediate relief.

Back pain can be caused by a variety of pathologies, such as disc lesions, herniations, or degeneration of joints and cartilage. These conditions can lead to muscle and bone pain, making it difficult to stretch or perform daily activities. Infiltration often targets areas where nerves are compressed by spinal structures, helping to reduce pain and improve the patient's quality of life.

This procedure can also be beneficial for those suffering from chronic pain linked to muscle or joint disorders. For example, when a lumbar muscle is strained or a vertebra is injured, the injection can help reduce pain by relaxing the surrounding muscles and allowing greater mobility. Doctors may recommend stretching and rehabilitation sessions after infiltration to strengthen back muscles and prevent recurrence of pain. In short, infiltration of the lumbar spine is an effective treatment for back pain, enabling patients to regain better function and greater ease in their daily activities.
