Parsonage-Turner Syndrome After Bacterial Pharyngitis in Childhood With Resulting Glenohumeral Joint Subluxation in Adulthood.

Abstract

Abstract: Parsonage-Turner syndrome (PTS), also known as neuralgic amyotrophy, presents with unilateral shoulder pain, followed by weakness. Associated sensory symptoms such as numbness may also occur. Contrary to the traditional thought that the condition typically self-resolves within weeks or gradually reaches full recovery with conservative management, more recent reports have revealed that a large portion of affected individuals experience persistent symptoms. We present an unusual case in which the patient developed PTS associated with streptococcal pharyngitis as a child, and his shoulder symptoms did not recover despite ongoing physical therapy. By young adulthood, he developed high-grade glenohumeral joint subluxation on the verge of full dislocation. Furthermore, imaging demonstrated the possibility of a reverse Hill-Sachs deformity. In addition to resumption of physical therapy, the patient has been referred to a tertiary care center to determine whether tendon transfer is a viable treatment option.
