Lee KT, Kim JB, Young KW, Park YU, Kim JS, Jegal H. abstract here
- tenderness in the 3-4th intermetatarsal space.
- when squeezing pressure is applied to the intermetatarsal space, a painful and palpable clicking sensation is induced (Mulder’s sign).
- (if you are good, you can feel an enlargement where neuroma is)
- Ovoid mass on ultrasound
- failed NSAID’s, metatarsal pads, shoe modification, and steroid injection for 6 months
- Pain improved from 8.6 to 2.4/10
- There have been 8 studies – followup 4-10 years – good results in 51- 85% of cases
(present study, of 13 cases, got 10 years satisfaction of 61%)
- Side effect included some continued pain and unsettling numbness in 3rd and 4th toes.
Comment – Steroid or alcohol injections are alternatives but the former could thin fat pad under foot, and cause issues there, if injected too deep
