Thoracic Outlet Syndrome Causing Phantom Hand Pain in a Person With a Transradial Amputation: A Case Presentation

In this case, a 47-year-old commercial truck driver with a remote right transradial amputation presented with pain in the medial aspect of his right phantom hand. He was diagnosed with thoracic outlet syndrome (TOS). This was attributed to the muscular demands associated with using his body-powered prosthesis for many years. TOS remains a controversial diagnosis in the able-bodied population and a unique diagnostic challenge in a patient with a transradial amputation. In this case, consideration of TOS guided the rehabilitation and treatment plan. His pain improved with a conservative stretching program.
