5-Minute Summary: Image-guided injections versus anatomical-based injections for carpometacarpal (CMC) arthritis: A Systematic Review

Thumb carpometacarpal (tCMC) arthritis is a common and debilitating condition for aging people worldwide. Conservative treatments including activity modification, bracing, anti-inflammatory medications, and steroid injections remain the initial treatment of choice. Given the size of the tCMC joint, intra-articular image-guided injections (IGI) may provide more consistent and superior outcomes with comparison to peri-articular anatomic landmark injections (ALI). This study systematically reviews the accuracy and efficacy of intra-articular IGA versus ALI.
