Etiology of symptomatic recurrent interdigital neuromas
Summary
Recurrent Morton's neuroma symptoms stem from amputation neuromas forming plantarly. This study explains their location and offers a surgical method to reduce recurrence after neuroma resection.
Area of Science:
- Podiatric surgery
- Nerve pathology
Background:
- Morton's neuroma is a common foot condition often treated surgically.
- Symptom recurrence after neuroma resection can occur due to amputation neuroma formation.
Purpose of the Study:
- To provide an anatomical and biomechanical explanation for the location of symptomatic amputation neuromas.
- To propose a method for reducing neuroma recurrence.
Main Methods:
- Intraoperative observations during surgery for recurrent neuromas.
- Cadaver dissections to analyze nerve pathways and anatomical structures.
Main Results:
- Symptomatic amputation neuromas are consistently found on the plantar surface.
- Neuromas are located proximal to metatarsal condyles and medial to the nerve resection interspace.
Conclusions:
- The anatomical and biomechanical theory explains amputation neuroma location.
- The proposed method aims to decrease the incidence of recurrent Morton's neuroma symptoms.
