[Fractures and dislocations of the lumbar vertebrae (author's transl)].

The authors report 6 cases of fracture and dislocation of the lower lumbar vertebrae (L3, L4, L5) and note that they were usually lesions following violent trauma usually in hyperflexion. The following were treated 1 dislocation L3-L4, 2 dislocations L4-L5, 2 comminuted fractures of L4, 1 fracture of L5, and included in all cases intersomatic arthrodesis at one (five cases) level or two levels (one case) and one posterior internal fixation with Kempf's material. The simplicity of the follow up and the stability of the fixation, permit us to propose the method for all unstable lesions of the lower lumbar vertebrae.
