Table 4 Facet joint forces at instrumented levels and adjacent levels under extension

From: Application of an interspinous process device after minimally invasive lumbar decompression could lead to stress redistribution at the pars interarticularis: a finite element analysis

Motion Model L2-L3 (N) L3-L4 (N) L4-L5 (N)
Extension INT 25 (100%) 35 (100%) 45 (100%)
DEF 21 (84%) 29 (83%) 43 (96%)
DIAMUNI 26 (104%) 24 (69%) 50 (111%)
DIAMBIL 27 (108%) 25 (71%) 51 (113%)
  1. The percentages indicate the facet joint forces of all the models normalized by the corresponding facet joint forces of the INT model
