Carpal tunnel syndrome (CTS) is a condition caused by compression of the median nerve as it travels through the carpal tunnel in the wrist. This compression can lead to symptoms such as pain, numbness, and tingling in the hand and fingers. Carpal tunnel syndrome injections are a common treatment option to alleviate these symptoms.
Mechanism
The injection for carpal tunnel syndrome typically involves administering a corticosteroid medication directly into the carpal tunnel. This anti-inflammatory medication helps reduce swelling and pressure on the median nerve, providing relief from pain and discomfort.
Procedure
The procedure for a carpal tunnel injection involves:
Preparation: The area around the wrist is cleaned and sterilized to prevent infection. Local anesthesia may be administered to numb the injection site.
Injection: Using a syringe and needle, the corticosteroid medication is injected into the carpal tunnel. The physician may use imaging guidance, such as ultrasound, to ensure accurate placement of the injection.
Post-Injection Care: After the injection, patients may be advised to rest the wrist and avoid activities that could exacerbate symptoms. Ice packs may be applied to reduce swelling.
Benefits
Pain Relief: The corticosteroid injection can provide significant pain relief by reducing inflammation and pressure on the median nerve.
Improved Function: Many patients experience improved hand function and reduced symptoms following the injection.
Non-Surgical: The injection is a non-invasive treatment option that can help delay or avoid the need for surgery.
Risks and Complications
Infection: Although rare, there is a risk of infection at the injection site.
Allergic Reaction: Some patients may experience an allergic reaction to the medication.
Temporary Pain or Discomfort: Mild pain or discomfort at the injection site is common and usually resolves on its own.
Effectiveness
The effectiveness of carpal tunnel injections varies among individuals. Some patients experience long-lasting relief, while others may require multiple injections or additional treatments. In cases where symptoms persist despite injections, surgical options such as carpal tunnel release surgery may be considered.
