Radius and Ulna Stress Fractures in a Patient with Neuromyelitis Optica: A Case Report
نویسندگان
چکیده
Introduction Stress fractures are more common in the weight-bearing bones of the lower limb and are particularly prevalent in athletes. Whereas, those of the upper limb are usually reported as unique events in rare circumstances. Case Report We present a case of a 40-year-old White British female with neuromyelitis optica (NMO) who mobilized in a wheelchair and presented to our center in April 2016 with a week-long history of a hot, swollen, and unstable right forearm. Plain radiographs demonstrated fractures of both the radius and ulna of the dominant right arm. These were managed by open reduction and internal fixation to facilitate mobility and transfer using the forearm. Intra-operatively, these were confirmed to be fatigue fractures, and there was evidence that the fracture was several days old. The neurological deficit in this patient had led to a delayed presentation owing to the lack of pain. Unfortunately, this construct failed within 8days, and a refixation was performed 2months later. 1year following the revision, no further problems have been reported, and there has been satisfactory union. Conclusion This is the first report in the published literature of a stress fracture in a patient with NMO. We recommend screening for stress fractures with a nuclear bone scan in patients who mobilize in atypical ways, particularly if their sensation is compromised. The use of constructs stronger than those routinely applied to the upper limb should also be considered if patients are weight bearing through their arms.

متن کاملSegmental radius and ulna fracture with epiphyseal involvement: a case report.
Segmental fractures of the radius and ulna are relatively common in adults, often occurring after high energy trauma. Segmental forearm fractures in children have not previously been reported, and their optimal management is unclear. We report a child of eight years of age who underwent fixation of these injuries with a good outcome.

Background: Neuromyelitis Optica Spectrum Disorder (NMOSD) is an autoimmune neurological disorder that is characterized by optic neuritis and longitudinally-extended transverse myelitis lesions in spinal segments.

INTRODUCTION Diaphyseal fractures of both bones of the forearm are commonly encountered in clinical practice. Segmental radius shaft fractures are, however, less commonly seen. We hereby report two cases of segmental complex radius fracture with mid-shaft ulna fracture. Such type of cases are reported previously in children but rarely in adults.

INTRODUCTION Simultaneous radius and ulna fractures are common in adults and generally osteosynthesis with plating is the treatment of choice. Nailing of such fractures is infrequently advocated. We present our unique technique of radius ulna nailing in adults to achieve closed reduction and early predictable union with minimal or no complications.
