AIM To explore the morphology of neuromas and to determine the differences, if any, between asymptomatic and symptomatic neuromas using ultrasound.
MATERIALS AND METHODS Eighty patients with symptomatic neuromas were included in this retrospective review. High-resolution ultrasound examination was performed. Transducer pressure allowed real-time analysis of both symptomatic and asymptomatic neuromas. Quantifiable assessment of pain by the patient assigned a pain score of 0, 1, 2, or 3, to each neuroma.
RESULTS One hundred and fifty-nine neuromas were identified in total. Fifty-three neuromas were asymptomatic (pain score=0), very severe pain was recorded in 54 (pain score=3), 16 neuromas were mildly painful (pain score=1) and 36 were moderately painful (pain score=2). The average number of neuromas per patient was 1.98, and the average number of symptomatic neuromas per patient was 1.3. There was no correlation between pain score and patient age, neuroma volume, amputation type, and time since amputation.
CONCLUSIONS High-resolution ultrasound can distinguish between asymptomatic and symptomatic neuromas. Patient age, time since amputation, the type of amputation, and the neuroma volume were not related to the presence of pain.
