Local Corticosteroid Injections versus Surgical Carpal Tunnel Release for Carpal Tunnel Syndrome: Systematic Review and Meta-Analysis.

Both CTR and LSIs were effective and feasible in reducing symptoms of carpal tunnel syndrome. Though LSIs led to greater pain relief, this superiority was not permanent. Irrespective of the severity of the symptoms, current evidence suggests that a cycle of LSIs may be considered in patients with CTS. However, patients must be aware that LSIs may not be the definitive therapy, and CTR should be recommended.
