Among the various resources used in orthopedics, immobilization is a tool commonly used in the treatment of bone and musculoskeletal injuries. The objective of the present study was to perform a structural biomechanical evaluation of the spine of rats submitted to immobilization and recovered with swimming training. Thirty-two female Wistar rats were divided into four groups: Control (CTR), Fixed Assets (I), Fixed Assets / Swimming (IN) and Swimming (NA). Immobilization occurred in the right hind limb, including the pelvis, hip, femur, knee (extension), tibia, and ankle (plantar flexion) for two weeks. Swimming training occurred for six days a week over two weeks. After this period the animals were sacrificed and the L6 and T13 vertebrae were dissected and the areas of interest were subsequently measured. The animals submitted to the immobilization model showed metrical changes in the vertebral column. The results emphasized that the movement restriction is not restricted to the immobilized region, but it can also affect other adjacent structures in a systemic way. [ABSTRACT FROM AUTHOR]

In the literature, there is no evidence of relationship between primary bone lymphoma and osteochondroma or of coexistence of both of them in a single bone. The present report describes an uncommon case of primary bone lymphoma occurring simultaneously with osteochondroma in the proximal third of the tibia. In the present case, magnetic resonance imaging signs simulated the presence of sarcomatous degeneration. [ABSTRACT FROM AUTHOR]
