Bone changes in Gaucher disease

These are: nonspecific skeletal and joint pain, purulent osteomyelitis, pseudo-osteomyelitis, aseptic necrosis of the femoral head, pathologic fractures of the long bones, acutely occurring kyphosis secondary to pathologic vertebral fractures with or without spinal compression, bony deformities, growth disturbances, arthritis, and bursitis. Various pathogenic mechanisms have been discussed: toxic reaction to the Gaucher cells, disturbance of the osteoblastic and osteoclastic function, compression of osseous blood vessels by pathological cells, pressure-induced atrophy of the surrounding osseous tissue, local hemorrhage, local thrombosis, invasion of the arterioles with subsequent occlusion, and bone infarcts. The case of a patient with multiple fractures of the spine and a slight spinal compression is presented
