Objective: To explore the characteristics of the injuries in thoracolumbar burst fractures occurring with laminar fractures and associated dural laceration.

Objective To analyze the trauma mechanism of the lamina fractures and dural tears and cauda equina entrapment in L2-L5 burst fractures, and to explore the relationship between the two.

Objective To determine the incidence and mechanism of dural tears in burst fractures of the second through fifth lumbar vertebrae with lamina fractures and to find out if any specific clinical and radiographic factors are predictive of dural tears and cauda equina entrapment.
