Rare Case of Dynamic Thoracic Outlet Syndrome Resolved by an Isolated Subclavius Posticus Muscle Resection: A Case Report.

Case: We reported a dynamic neurogenic left thoracic outlet syndrome (TOS) with a permanent abduction of the fifth left finger. Preoperative magnetic resonance imaging (MRI) assessed the presence of subclavius posticus muscle (SPM). Because of a nonoperative treatment failure, we performed a brachial plexus neurolysis and SPM resection.
