This study compares the effectiveness of two types of local injections-Hyaluronic Acid (HA) and corticosteroids-for treating mild to moderate idiopathic Carpal Tunnel Syndrome (CTS). Sixty adult patients will be assigned to receive one of the two injections under ultrasound guidance. The goal is to see if HA is as effective as the standard corticosteroid treatment in improving symptoms and nerve function over a 3-month follow-up period.
Numbness or pain in the Median Nerve (MN) distribution.
Nerve conduction studies (NCS) consistent with CTS as per the AANEM guidelines.
An MN cross-sectional area (CSA) at the wrist >12 mm²
Patients with severe symptoms (indication for surgery).
Patients who show improvement on medical treatment.
Patients with previous surgical or injectional CTS treatment.
Coexistence of brachial plexopathy, or thoracic outlet syndrome.
