Summary

A corticosteroid injection proximal to the carpal tunnel effectively treated carpal tunnel syndrome (CTS), with 77% of patients improving after one month. This treatment offers a significant benefit for CTS relief.

Area of Science:

  • Neurology
  • Orthopedics
  • Pain Management

Background:

  • Carpal tunnel syndrome (CTS) is a prevalent condition characterized by median nerve compression at the wrist.
  • Symptoms include hand numbness, reduced dexterity, muscle wasting, and impaired functional ability.
  • This study evaluates a novel corticosteroid injection technique for CTS management.

Purpose of the Study:

  • To assess the efficacy of a corticosteroid injection administered proximal to the carpal tunnel for treating carpal tunnel syndrome.
  • To compare the outcomes of corticosteroid injection versus a placebo injection in CTS patients.

Main Methods:

  • Sixty patients with confirmed CTS for over 3 months were randomized into two groups: intervention (lignocaine and methylprednisolone) and control (lignocaine only).
  • Injections were administered 4 cm proximal to the wrist crease, avoiding direct injection into the carpal tunnel.
  • Outcomes were assessed at 1 month, with improvement defined as self-reported absence or minor residual symptoms.

Main Results:

  • Seventy-seven percent of patients receiving the corticosteroid injection improved at 1 month, compared to 20% in the control group (P <.001).
  • The number needed to treat was 1.8, indicating high efficacy.
  • No significant side effects were reported from the injections.

Conclusions:

  • Corticosteroid injection proximal to the carpal tunnel is a safe and highly effective treatment for carpal tunnel syndrome.
  • This minimally invasive approach provides rapid symptom relief and may reduce the need for surgery.
  • Further research could explore long-term outcomes and reproducibility across different clinical settings.
