Fig. 8From: Imaging in the diagnosis of ulnar nerve pathologies—a neoteric approacha Thickened hypoechoic ulnar nerve (yellow arrow) getting compressed by orthopaedic implant—K wire (red arrow). b Ring down artefact on colour Doppler shows the orthopaedic implant (red arrowhead) compressing the hypoechoic ulnar nerve which also shows increased vascularity suggestive of neuritis (yellow arrow). c Plain radiograph of the same patient shows the implant following intervention for an olecranon fracture. d Colour Doppler image of the same patient showing hypervascularity of the ulnar nerve (yellow arrow) which co-relates with higher grade of neuritis due to compression or inflammation [41]Back to article page
