Comparison of proximal and distal corticosteroid injections for carpal tunnel syndrome.

Introduction: Evidence for the efficacy of distal corticosteroid injection compared with proximal injection in carpal tunnel syndrome (CTS) is inadequate.

Methods: We conducted a randomized, double-blind noninferiority trial of 131 wrists with CTS. Forty milligrams of methylprednisolone was injected medial to the palmaris longus tendon 2 cm proximal to the wrist crease, or at the volar aspect, 2 to 3 cm distal to the wrist crease.

Role of Ultrasound to Monitor Patients With Carpal Tunnel Syndrome Treated With a Local Corticosteroid.

Objectives: Carpal tunnel syndrome (CTS) is an entrapment neuropathy resulting from compression of the median nerve at the carpal tunnel (CT). We assessed the role of high-resolution ultrasound (US) in monitoring patients with CTS treated with corticosteroid injection.

Methods: We performed high-resolution US evaluations of the wrists of patients with CTS before and after treatment with local corticosteroid.
