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.
