Abstract
OBJECTIVE
The purpose of this report is to describe a new sonographically guided technique for carpal tunnel injections using an Ulnar approach.
METHODS
Previously published sonographically guided techniques for carpal tunnel injections were reviewed. Described approaches were noted to be technically challenging because of the need to perform long-axis imaging of the carpal tunnel, short-axis (out-of-plane) imaging of the needle, or both.
RESULTS
We developed and herein describe the ulnar approach for sonographically guided carpal tunnel injections. Advantages of this approach include transverse imaging of the carpal tunnel, long-axis (in-plane) imaging of the needle, and versatility in targeting structures within the carpal tunnel.
CONCLUSIONS
Clinicians should consider the ulnar-sided approach when performing sonographically guided carpal tunnel injections.
