Abstract:
Although, trauma, foot deformity (pesplanovalgus), systemic diseases such as diabetes mellitus and lupus, drugs (steroids, antineoplastic) and excessive alcohol consumption have all been accused in the etiology of avascular necrosis of the tarsal bones, spontaneous avascular necrosis of the navicular bone, especially in adults, is a rare entity. In this article, we report a 50-year-old female patient with bilateral, spontaneous avascular necrosis of the navicular bone and related severe talonavicular arthrosis. Clinical and radiological findings were concordant with Müller-Weiss disease, which is a rare disease with complex idiopathic foot condition of the adult tarsal navicular bone characterized by progressive navicular fragmentation and talonavicular joint destruction. The patient was successfully treated with two-staged bilateral talonavicular arthrodesis.
Insights
Spontaneous avascular necrosis of the navicular bone is rare in adults. This case report details a successful bilateral talonavicular arthrodesis for Müller-Weiss disease, a complex idiopathic foot condition.
Area of Science:
- Orthopedics
- Podiatry
- Radiology
Background:
- Avascular necrosis of tarsal bones has multiple known causes, including trauma, systemic diseases, and certain medications.
- Spontaneous avascular necrosis of the navicular bone, particularly in adults, is an uncommon condition.
Observation:
- A 50-year-old female presented with bilateral spontaneous avascular necrosis of the navicular bone and severe talonavicular arthrosis.
- Clinical and radiological findings were consistent with Müller-Weiss disease.
Findings:
- Müller-Weiss disease is a rare, idiopathic condition affecting the adult tarsal navicular bone.
- It is characterized by progressive navicular fragmentation and talonavicular joint destruction.
Implications:
- This case highlights the successful management of bilateral Müller-Weiss disease using a two-staged bilateral talonavicular arthrodesis.
- The findings contribute to understanding treatment options for this rare foot condition.
