Single-staged, temporary bisegmental	33 (54.1%)
Two-staged, temporary bisegmental	22 (36.1%)
Type of LLIF implant

Expandable (Globus Medical ELSA ®)	7 (11.5%)

^⁎The interval between the posterior and lateral procedure was 2.6 days (SD 3.7) in the immediate group and 102.8 (SD 37.8) days in the staged group (p<0.001).

^†In 53/55 patients with bisegmental treatment, the noninjured motion segment was released by removal of pedicle screws and shortening of rods after an interval of 133.9 days (SD 40.7) following the initial surgery.

Data is presented as mean (standard deviation) or count (percent).
