RESUMO
INTRODUCTION AND IMPORTANCE: Ankle fractures result from a wide variety of mechanisms the biomechanics of this articulation make any fracture altering the contact of the articulation surface lead to increased stresses and an inevitable evolution to tibiotalar arthritis. CASE PRESENTATION: We report the case of a 56-year-old patient admitted for open fracture dislocation of the ankle with a missing medial malleolus. He was treated by external fixation k-wiring and periosteal repair of the deltoid ligament. The one-year follow-up shows a good functional outcome with the patient's satisfaction. CLINICAL DISCUSSION: In ankle fractures, some authors report no need for fixation of the medial malleolus. Furthermore, the absence of the medial malleolus is not necessarily accompanied by instability of the ankle; however, it inevitably leads to ankle osteoarthritis. CONCLUSION: Our patient admitted for a bimalleolar fracture with missing medial malleolus, as described in the literature, had a favorable evolution with a functional score that was judged fair.
