ABSTRACTBackground: heterotopic ossification is the formation of ectopic lamellar bone containing bone marrow. The physiopathology is not known in its entirety. The treatment is based on non-steroid anti-inflammatory drugs, radiotherapy, biphosphonates, surgery, and physical therapy.
Objective: to present a case of neurogenic heterotopic ossification of the right hip caused by limited articular mobility and truncal sciatica.
Clinical case: a twenty-eight-year-old male patient with antecedents of severe traumatic brain injury. The patient stayed in bed for two months in a critical condition. A year later, his right gluteal region started to grow and he presented a slight pain in the leg that made him difficult to sit associated to debility with distal predominance (pendular feet) and hypoesthesia. In the physical examination, a tumor mass of hard consistence and fix to deep planes, painless with positive signs of Tinel in the emergence of the sciatic nerve, was found in the right gluteal region. In the radiography of the right hip, an osseous tumoral image was seen. A conservative treatment was started without any improvement, that’s why a surgery was conducted to remove the osseous mass, obtain the histological diagnosis and improve the symptomatology.
Conclusions: neurogenic heterotopic ossification is a complication that appears in patients with severe craniocerebral trauma. The clinical manifestations are not specific and the diagnosis is determined by means of imaging and confirmed through histopathology. The surgical treatment offers the best results. The recurrence can be minimized when combining non-steroid anti-inflammatory drugs, radiotherapy and rehabilitation.
