Spondylolisthesis

Spondylolisthesis

Spondylolisthesis is a forward slippage of the vertebral body engendered by a break in the continuity or elongation of the pars interarticularis and presents in 4% of the adult population. Spondylolisthesis can be classified into six types by causation ( Table 37.8 ) or by the degree of slip ( Table 37.9 ) . For skeletally immature patients (<18 years old) who have progressive slips in the spine, and in individuals with intract able low back or radicular pain or neurological symptoms, sur gery may be indicated. For low-grade slips (Meyerding grades I and II) fusion- in-situ is the procedure of choice. If there is objective evidence of neural compression (e.g. weakness of extensor hallucis longus), a spinal decompression should be performed at the same time. For high-grade slips (Meyerding grades III or IV) ( Figure 37.5 ), opinion is divided on whether to reduce the slip first and then fuse, or simply to fuse in situ Spondylolisthesis
