“…El proceso de necrosis ósea y de tejido medular, habiéndose excluido infección, se denomina infarto óseo, particularmente cuando se ubica en la diáfisis y metáfisis oseas. El mismo proceso también es conocido como necrosis avascular o aséptica cuando se ubica en la epífisis [8][9][10] . A pesar de existir esta diferenciación en la terminología, muchas veces en la literatura, se describe este proceso de forma indistinta 11 .…”

“…A pesar de existir esta diferenciación en la terminología, muchas veces en la literatura, se describe este proceso de forma indistinta 11 . Hoy en día se han identificado poblaciones de riesgo para presentar infarto óseo y necrosis ósea avascular, estando documentados en pacientes con anemia de células falciformes, talasemia, enfermedad de Gaucher, pacientes diabéticos, enfermedades mieloproliferativas, trasplante renal y uso de terapia crónica esteroidal [9][10][11][12] . El infarto óseo puede presentarse en forma crónica, siendo clínicamente asintomático u oligosintomático, y visualizándose en forma incidental por exámenes imagenológicos.…”

“…MRI is much more sensitive than plain radiography to show bone infarction and may show changes caused by altered hemodynamics early in the course of disease. 4 Spine MRI showed scattered areas of patchy enhancement along the midportion of multiple vertebral bodies within the cervical, thoracic, and lumbar spine consistent with bone marrow infarction (figure).…”

[1][2][3] Iako osteonekrotično ošteće nje može spontano regredirati, ipak u većine bolesnika dolazi do napredovanja bolesti, propadanja zglobne hrskavice i nastanka sekundarnog osteoartritisa.

Spontaneous osteonecrosis of the knee (SONK) is the most common type of knee osteonecrosis. It causes subchondral bone damage and in the majority of cases leads to cartilage damage and secondary osteoarthritis. The etiology is commonly explained with two main theories, vascular and traumatic. Vascular theory is based on disrupture of bone blood supply which causes local ischaemia and subchondral bone necrosis. Traumatic theory suggests the development of subchondral insufficiency fractures due to mechanical overload, which causes local oedema, ischaemia and necrosis. SONK typically appears in middle age and older women, with acute onset of sharp pain in the medial femoral condyle without predisposing trauma. Considering that the characteristic radiological signs are not seen on conventional radiography until advanced stage, magnetic resonance imaging is the gold standard in diagnostics. Treatment depends on the size and stage of the osteonecrotic lesion. Small osteonecrotic lesions are usually successfully treated non-operatively, which is based primarily on protected weight bearing and physical therapy. Medium osteonecrotic lesions are treated either non-operatively or operatively, while large osteonecrotic lesions are almost always treated operatively. Most commonly used joint preserving procedures include arthroscopic bone marrow stimulation using microfracture technique, core decompression, osteochondral autologous or homologous transplantation, artificial graft transplantation, and medial opening-wedge high tibial osteotomy. The treatment of choice after subchondral bone collapse is knee arthroplasty.
