Cubital Tunnel Syndrome (CuTS) is the 2nd most common compressive neuropathy affecting 6% of the population. Surgical decompression is the most effective treatment, but clinicians lack a reliable test to select patients for surgery. Diffusion tensor imaging (DTI) characterises tissue microstructure and so, DTI was acquired from 14 controls and 8 patients awaiting surgery in this proof-of-concept study. Patients had a significantly lower FA and higher RD than controls, throughout the length of the ulnar nerve. Therefore, DTI may add objective evidence of the ‘health’ of the ulnar nerve and aid the management of cubital tunnel syndrome.
