Carpal Tunnel Syndrome
Aims and objectives
Aim:
To understand the diagnosis and management of carpal tunnel syndrome (CTS)
Objectives:
Define CTS
Identify the carpal tunnel, median nerve, ulnar artery and ulnar nerve on a diagram of the hand
Identify the roots, trunks, division, cords and main branches of the brachial plexus on a diagram
Recognise the common symptoms of CTS
Recognise the risk factors for CTS
Establish a differential diagnosis for CTS
Interpret the clinical test performed for suspected CTS
Identify the dermatomal and nerve innervation of the hand
Interpret the investigations that occur when diagnosing CTS
Compare the treatment options in CTS
NOTE: The anatomy part of this tutorial will be covered in the musculoskeletal block of Systems 3.
