Mucormycosis in compound grade IIIa tibial plafond with medial malleolus fracture: A case report

Abstract

Tibial plafond fracture is defined by intra articular involvement of the distal tibia with metaphyseal extension. The plafond fracture accounts for less than 1% of lower limb injuries and 3–10% of tibial fractures. The rate of deep infection in open ankle fractures is approximately 5%. Pilon fractures are frequently associated with severe soft- tissue injuries that alter the management plan. Here we describe the case of 35year old man brought to ER after sustaining machinery injury to right ankle. On local examination a Laceration of 7x2x2 cms present over left ankle anteriorly extending from Medial Malleolus to Lateral Malleolus and cut ends of tendons of extensor digitorum longus, extensor hallucis longus and Tibialis anterior were identified. X-ray left ankle Ap and Lateral views were taken. X-ray showed Left Distal Tibia fracture. Thorough Wound wash given. Under spinal anesthesia debridement of wound was done and K-wire fixation done for distal tibia fracture. Tendon repair for extensor digitorum longus, extensor hallucis longus and tibialis anterior done using Ethibond suture material using Modified Kessler Technique. On 2 Post operative day a swab from the wound site sent for culture and sensitivity which revealed fungal growth of zygomycetes species. In view of angioinvasive properties of Zygomycetes, after checking Renal parameters patient was started on Inj Amphotericin B 1mg/kg for 4 days and later converted to Tablet Posaconazole 600mg BD. Patient was kept on posaconazole tablet for 6weeks. Regular dressings were done. On regular follow ups and regular dressings wound healed well.
