Objective: Lumbar interbody fusion (LIF) entails the placement of a
bone graft within the intervertebral space, with or without the use of a
cage, subsequent to discectomy. While numerous studies have explored
caged LIF methods within the literature, limited attention has been given
to direct comparisons between caged and cageless LIF techniques.
This study aims to scrutinize the delayed outcomes of interbody fusion
involving peek-caged and cageless laminar autografts. The investigation
was specifically carried out at the L4-5 level.
Method: This retrospective comparative study was conducted on patients
who underwent surgical procedures at our institution’s neurosurgery
clinic between 2011 and 2018, with the sanction of the ethics committee
from the same institution. The study group (Group 1, n=27) comprised
patients who underwent L4-5 single-level lumbar instrumentation and
transforaminal LIF using a banana cage alongside autograft for the
purpose of fusion. The control group (Group 2, n=31) consisted solely
of cases that underwent posterior LIF operations with the utilization of
autografts. Corticocancellous bone fragments sourced from posterior
structures during decompression were utilized as autografts. The study
parameters encompassed fusion rates, segmental and lumbar lordosis
angles, disc height, ipsilateral and contralateral foramen heights, as well
as slip distance.
Results: Within our study, the late-stage fusion rates were determined to
be 96.3% in the caged group and 96.7% in the cageless autograft group.
No alterations were identified in segmental and lumbar lordosis angles
across both groups. Notably, the caged group exhibited a propensity for
late-stage cage embedding, while graft migration was the most prevalent
complication within the autograft group.
