Chronic Midfoot Pain Due to Idiopathic Osteonecrosis of Tarsal Navicular Bone in Adult - Mueller-Weiss Syndrome: A Case Report.

Abstract

Introduction: Mueller-Weiss syndrome is a rare condition seen in adults due to spontaneous osteonecrosis of tarsal navicular bone unlike Koehler's disease which is quite common in paediatric population.

Case report: We report a single case of Mueller-Weiss syndrome in an adult female. After a trail of conservative treatment, operative management was done with excision of necrotic fragment and arthrodesis of mid-foot joints augmented with tricortical iliac crest graft. Good fusion and significant reduction of pain on weight-bearing was observed after a duration of 6 weeks.

Conclusion: Mueller-Weiss syndrome is relatively rare differential for mid-foot pain in adult population. Early recognition and management of the condition prevents arthritic changes and disability.
