What is it?
Infiltrations are medical procedures that involve the direct administration of medications into specific tissues, joints, muscles, or anatomical spaces where pain or inflammation originates. This technique allows therapeutic concentrations of medication to be delivered precisely to the affected area, maximizing effectiveness while minimizing systemic side effects.
The procedure uses specialized needles to inject medications such as corticosteroids, local anesthetics, hyaluronic acid, or tailored combinations depending on the condition being treated. Infiltrations may be performed under ultrasound or fluoroscopic guidance, or using anatomical landmarks, ensuring accuracy in medication delivery. Depending on the target area, they may be intra-articular, periarticular, epidural, applied to trigger points, or administered into specific soft tissues.
What is it used for and what diseases or chronic pains does it treat?
Infiltrations are effective for a wide range of musculoskeletal conditions and localized pain, including:
- Arthritis and osteoarthritis of the knee, hip, shoulder, and other joints
- Lumbar and cervical pain treated through epidural or facet infiltrations
- Tendinitis and bursitis of the shoulder, elbow, wrist, hip and ankle
- Carpal tunnel syndrome and other compression neuropathies
- Plantar fasciitis and heel pain
- Rotator cuff syndrome and shoulder injuries
- Sacroiliac pain and joint dysfunction
- Muscle trigger points and myofascial pain syndrome
- Herniated discs with associated radiculopathy
- Adhesive capsulitis (frozen shoulder)
- Morton’s neuromas and peripheral neuralgias
- Post-traumatic or degenerative joint pain
This treatment is ideal for patients seeking quick and targeted relief without the side effects of systemic medication.
Benefits compared to other treatments
Infiltrations offer significant advantages as a targeted therapeutic approach:
Direct action: Medications act precisely at the source of the problem, achieving optimal therapeutic concentrations.
Rapid relief: Patients often experience reduced pain and inflammation within hours or days after the procedure.
Minimal systemic effects: Localized administration significantly reduces side effects compared to oral or intravenous treatments.
Outpatient procedure: Performed in an outpatient setting, allowing for a quick return to normal activities.
Diagnostic value: A positive response can help confirm the exact origin of the pain.
Alternative to surgery: In many cases, infiltrations can delay or avoid more invasive surgical interventions
Repeatability: Procedures can be repeated based on clinical need and patient response.
Therapeutic combination: Can be combined with physical therapy and other treatments to enhance outcomes.
Cost-effectiveness: Provides an economical option with an excellent cost-benefit ratio.
Functional preservation: Helps maintain or restore joint and muscle function while controlling pain.
Infiltrations are a versatile and effective tool for the immediate and targeted management of musculoskeletal pain.
