Background: Success after lateral transpsoas interbody fusion (LLIF) partially depends on
avoidance of subsidence to maintain spinal alignment, disc space height, and indirect …

Introduction: Few studies have investigated the influence of cage subsidence patterns
(intraoperative endplate injury or late-onset cage settling) on bony fusion and clinical …

Background All interbody fusions are associated with a risk of subsidence. In the case of
lateral lumbar interbody fusion (LLIF), an interbody device that spans the apophyseal rings …

Purpose The LLIF procedure is a useful stand-alone and adjunct surgical approach for many
spinal conditions. One complication of LLIF is subsidence of the interbody graft into the …

OBJECTIVE Lateral lumbar interbody fusion (LLIF) facilitates the restoration of disc height
and the indirect decompression of neural elements. However, these benefits are lost when …

Object Lateral transpsoas interbody fusion (LTIF) permits anterior column lumbar interbody
fusion via a direct lateral approach. The authors sought to answer 3 questions. First, what is …

Object Indirect decompression of the neural structures through interbody distraction and
fusion in the lumbar spine is feasible, but cage subsidence may limit maintenance of the …

OBJECT Intervertebral cage settling during bone remodeling after lumbar lateral interbody
fusion (LIF) is a common occurrence during the normal healing process. Progression of this …

OBJECTIVE Transpsoas lateral interbody fusion is one of the lateral minimally invasive
approaches for lumbar spine surgery. Most surgeons insert the interbody cage laterally and …

Background Few data are available on the occurrence after stand-alone lateral lumbar
interbody fusion (LLIF) of implant subsidence, whose definition and incidence vary across …
