Evaluating Palpation Guided Injections in Trapeziometacarpal Arthritis

The objective of this study is to evaluate the accuracy of trapeziometacarpal injections using palpation alone. The importance of this study is one of education, cost containment, and decreased risk to the patient. If it can be shown that the accuracy of trapeziometacarpal injections using palpation alone is similar to the reported accuracy of ultrasound and fluoroscopy, then these guided techniques may not be needed.
