[Morton's disease]

Area of Science:

• Orthopedics
• Podiatry
• Neurology

Context:

• Morton's disease is characterized by neuralgia and pseudo-neuroma formation in the interdigital spaces of the foot.
• It predominantly affects middle-aged and older women, often linked to the use of tight, high-heeled footwear.
• The condition typically presents as forefoot pain during ambulation.

Purpose:

• To summarize the etiology, clinical presentation, diagnostic methods, and treatment strategies for Morton's disease.
• To differentiate Morton's disease from other interdigital foot pathologies.
• To outline the indications for conservative versus surgical interventions.

Summary:

• Diagnosis involves physical examination (e.g., Mulder's test) and imaging (radiographs, MRI) to identify pseudo-neuromas and rule out other conditions.
• Conservative management includes footwear modification, orthotics, and diagnostic/therapeutic injections of corticosteroids and local anesthetics.
• Surgical excision of the pseudo-neuroma, typically via a dorsal approach, is indicated when conservative measures fail.

Impact:

• Provides a comprehensive overview of Morton's disease management for clinicians.
• Highlights the importance of accurate diagnosis for effective treatment selection.
• Emphasizes the role of conservative treatments and appropriate surgical indications in improving patient outcomes.
