Frequently this type of fracture becomes converted to a complete fracture. ⚫ An incomplete fracture with a cortical break in the tension side of the bone. The cortex on the compression side undergoes plastic deformation but remains intact 15min
Outlines requirements and time allocation 2、Simple fracture 15min .Which is bone fracture only there are no more than two pieces fragments,lucent line can be seen at the site of the fracture. 3.Communited fracture There are more than two pieces at the site of fracture.accompanying the dislocation of bone fragments 4、Open fracture Both bone and soft tissue are injury.It should be deal with just now.in oder to keep from infection. Differential diagnosis Imaging:according to the feature of X-ray and CTwe can know the type of the fracture and cope with it comrectly. Disease of Disc 20min Schmorl's node a protrusion of intervertebral disc material through a break in the subchondra bone plate with displacement of this material into the vertebral body.leading to an abnomma contour of the spine on radiographs Causes Intervertebral (osteo)chondrosis.Trauma.Hyperparathyroidism. Osteoporosis,Infection,Neoplasm They may result from any disease or condition that leads to weakening of the cartilaginous endplate or subchondral bone of the vertebral body Schmorl's nodes may sometimes be associated with a vacuum phenomenono fish vertebrae
