Positive test: reproduction of pain and/or paresthesias If having trouble finding the nerve Color Doppler Can be used to help find nerve, Interdigital artery runs adjacent to it Mulder's Click Test, in which the metatarsal heads are squeezed together, can also help identify the nerve Don't confuse with intermetatarsal bursitis Plantar Approach: Long Axis, In Plane Patient Position Prone Foot at position that is at comfortable height for practitioner performing injection Probe Position, Needle Orientation Start in short axis Once the needle is in the neuroma, turn the probe in long axis Needle is in plane Needle approach is distal-to-proximal Target Hyper- to hypoechoic to anechoic nodule at the level of the intermetatarsal space Pearls and Pitfalls Distinguish from intermetatarsal bursitis where the anechoic fluid is usually compressible Distinguish from metatarsalgia by direct palpation of the metatarsal joints Note that these three conditions can co-exist in the same patient Dorsal Approach: Long Axis, In Plane Patient Position Supine Knee flexed, forefoot hanging off end of examination table Foot at position that is at comfortable height for practitioner performing injection Probe Position, Needle Orientation Start in short axis Once the needle is in the neuroma, turn the probe in long axis Needle is in plane Needle approach is distal-to-proximal Target Hyper- to hypoechoic to anechoic nodule at the level of the intermetatarsal space Pearls and Pitfalls Distinguish from intermetatarsal bursitis where the anechoic fluid is usually compressible Distinguish from metatarsalgia by direct palpation of the metatarsal joints Note that these three conditions can co-exist in the same patient Aftercare No major restrictions in most cases Can augment with ice, NSAIDS Complications Skin: Subcutaneus fat atrophy, skin atrophy, skin depigmentation Painful local reaction Infection Hyperglycmia Tendon, nerve or blood vessel injury See Also References Mak, M
