Advanced imaging and arthroscopic management of shoulder contracture after birth palsy.

Overview

Modern imaging techniques applied to the pediatric glenohumeral joint have advanced understanding of the anatomic changes that occur secondary to muscular imbalance after brachial plexus birth palsy. A better understanding of the progression and timing of glenohumeral dysplasia has also increased awareness and vigilance of this problem. Early detection of glenohumeral joint subluxation is now possible, allowing for prompt treatment with closed, arthroscopic, or open joint reduction with and without tendon transfers. Dynamic ultrasound imaging, Botox, and arthroscopic techniques have expanded treatment options, providing minimally invasive methods to successfully manage glenohumeral joint dysplasia.
