Transient Osteoporosis and Osteogenesis Imperfecta: A Case Report

Síndrome de edema de la médula ósea de cadera

“…Hasta ahora, el único factor predisponente conocido es el embarazo y la incidencia parece ser mayor en pacientes con osteogénesis imperfecta que en la población general 42,43 . Algunos autores han reportado casos en los que se asoció con osteoporosis generalizada 3,30 pero otros han encontrado una densidad mineral ósea normal 2,34 .…”

Transient regional osteoporosis

“…Apart from that, there are disparities regarding cell death, fatty marrow necrosis, and bone turnover. Reports from some isolated cases described an increased number of resorption lacunae filled with osteoclasts, break lines representing microfractures, and slender trabeculae suggesting osteopenia or osteoporosis [42,43]. Other histological studies confirm focal areas of thin and disconnected bone trabeculae, which are compatible with osteopenia, but do not find increased activity in osteoclasts [24,44].…”

Dolore acuto non traumatico del ginocchio nell’adulto: ruolo della risonanza magnetica

“…According to these authors, there is an ischemic threshold that determines whether the lesion will progress from reversible BMO to irreversible AVN. Moreover, the role of the regional accelerated phenomenon activation has been stressed [14]. This theory was based on the frequent coexistence of systemic osteoporosis with TBMOS.…”

“…The radiographic findings may persist weeks after symptom resolution, and evidence of complete remineralisation may be delayed for up to 2 years [14][15][16]. Bone scan is considered very sensitive but not specific for detecting TBMOS.…”
