Abstract

|
|
Purpose: We wanted to compare the accuracy between the blind anterior approach and ultrasound guided posterior approach, which are preferred in the present clinical practice for the glenohumeral joint injection.
Materials and Methods: The consecutive 95 cases were included in that the glenohumeral joint injection was done in the university hospital and the medical record and ultrasonography were available. There were 52 cases which were injected by blind anterior approach (group I) and 43 cases who were injected by ultrasound guided posterior approach(group II). The injection was decided as accurate if the fluid was visualized in the posterior joint under the ultrasound. We evaluated the range of motion before and after 2 weeks of injection. A subjective satisfaction of the patients was interviewed at the 2 weeks after injection.
Results: The accuracy of the glenohumeral joint injections of the group I and group II was 80.8% and 90.7%, respectively. The range of motion was improved for the all cases regardless of the approaches. At the 2 weeks after injection, the subjective satisfaction (better than good) was achieved in 73.7%.
Conclusion: The accuracy of the blind anterior approach for the glenohumeral joint injection was 80.8%. The accuracy of the ultrasound guided posterior approach was 90.7%. In this comparative study by the one physician, the ultrasound guided posterior approach showed the better accuracy.
