The "Thumbs-up" sign and trapeziometacarpal joint injection: a useful clinical indicator.

ABSTRACT:

Background

Several clinical studies investigating the accuracy and efficacy of trapeziometacarpal injection exist. Some studies utilize anatomical landmarks for proper injection placement while others utilize modalities including ultrasound and fluoroscopy. The changes of limb position that occur at the time of intra-articular injection can provide valuable visual and tactile feedback to the clinician. The purpose of this study is to investigate the occurrence of the "Thumbs-up" sign with injection of the thumb trapeziometacarpal joint as a useful and reliable clinical indicator of intra-articular trapeziometacarpal injection and correlate level and duration of pain relief.

Methods

Trapeziometacarpal joint injections were performed on twenty-seven thumbs utilizing anatomic l
