Accuracy of non assisted glenohumeral joint injection in the office setting

Abstract

Purpose: The diagnostic and therapeutic success of shoulder joint injection depends on its accuracy. Two recent studies reported high success (93-96%) for non-imaging-assisted anterior injection in anesthetized patients. This study examined the accuracy of anterior shoulder injection in awake patients under conditions similar to the office setting.

Methods: The study group consisted of 166 consecutive patients with shoulder pain who underwent diagnostic magnetic resonance arthrography at a tertiary medical center in 2011-2012. As part of the examination, contrast material was injected into the glenohumeral joint via an anterior approach by a certified musculoskeletal radiologist without any image assistance. Success was defined as contrast material limited to the intra-articular joint on the scan, without scatter to the periauricular tissue.

Results: A successful injection was verified by magnetic resonance arthography in 163 patients (98.2%).

Conclusions: Non-assisted anterior shoulder injection is highly accurate (98.2%) in the hands of an experienced radiologist, even in awake patients.
