Osteosynthesis of an intertrochanteric fracture on osteopetrosis A case report.

INTRODUCTION: Osteopetrosis is a rare hereditary disease that can be transmitted in an autosomal recessive or autosomal dominant. CASE REPORT: Here, we report a case of trochanteric fracture in an 18-year-old boy with an anatomical plate. At the last follow-up, 24 months after surgery, the fracture had healed well, and the patient was not restricted in his activities. DISCUSSION: Osteopetrosis is a rare bone disease that is mainly caused by osteoclast dysfunction. It results from a remodelling defect that leads to hypermineralization of the skeleton, resulting in bone fragility. Both surgical and nonsurgical management have advantages and disadvantages. Thus, open reduction and anatomic plate fixation remain effective management modalities for trochanteric fractures in osteopetrosis patients. CONCLUSION: For our patient and as described in the literature, the complication rate decreases as some principles are respected with better consolidation of the osteoporotic fracture.

Post-traumatic missing medial malleolus: case report with a one-year follow-up.

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.
