Instrumental and clinical diagnosis of interdigital neuroma

Abstract

Abstract. Interdigital neuroma is one of the most common diseases in foot surgery. At the same time, the diagnosis of neuroma can be a difficult task for orthopedic surgeon. The main purpose of this study is to evaluate the importance of collecting anamnesis and complaints, clinical tests and MRI of the foot in the diagnosis Interdigital neuromas. Materials and methods: The study presents a retrospective analysis of the medical histories and outpatient records of 28 patients (8 men and 20 women) treated at EMC ECSTO in the period from 2017 to 2022. The examination was performed according to a standardized protocol: collection of complaints and anamnesis, palpation, manual testing, including Mulder's click test. As part of the examination, all patients did MRI of the foot. The average age at the time of surgical treatment was 45 years. Resection of a part of the affected nerve with subsequent histological examination was considered the "gold standard" in the treatment and verification of interdigital neuromas. Results: The sensitivity of MRI in the diagnosis of interdigital neuromas was 86%, the sensitivity of the Mulder test was 61%. Pain during palpation of the affected interdigital space was determined in 100% of cases. Conclusion: the combination of manual examination and MRI imaging, analysis of complaints and anamnesis makes it possible to diagnose Morton's neuroma in most cases.
