title: What factors predict the need for further intervention following corticosteroid injection of Morton's neuroma?
abstract: BACKGROUND
  This study investigated factors that may predict the need for Morton's neuroma (MN) to undergo further treatment within 2 years of a single ultrasound-guided corticosteroid injection.
  
  
  METHODS
  A retrospective study was undertaken over a three-year period. The data was stratified into two groups: Group A - did not receive further intervention and Group B - received further treatment. We investigated age, gender, neuroma size and presence of other forefoot pathology or ipsilateral neuromas.
  
  
  RESULTS
  54 patients (57 feet) were reviewed. 29 feet (51%) required further treatment within 2 years (11 repeat injections, 18 surgical excisions). Binary logistic regression showed that larger neuromas (p=0.011) and younger patients (p=0.007) predicted the need for further intervention but not gender (p=0.272). The distribution of concomitant forefoot pathology and ipsilateral neuromas were similar between the two groups.
  
  
  CONCLUSIONS
  Size and age appear to be predictors for further treatment of MN within 2 years of corticosteroid injection.
