Objective: Posterior lumbar interbody fusion (PLIF) techniques have been used for
many years for the treatment of a variety of lumbar spine degenerative diseases.
Patients with herniated disc disease in the lumbar spine at one or two levels,
unilateral or bilateral leg(s) pain, chronic low back pain and a failed conservative
treatment, were considered for this procedure. This paper discusses how many levels
of the spine are suitable for cages alone which the patient needs for the operation,
and which level is better than others when the patient undergoes single-level surgery.
Methods: Twenty-three patients (21: single level, 2: two levels) underwent a
posterior lumbar interbody fusion procedure in which A-spine titanium vigor cages
were used. At follow-up, the outcomes were assessed using the Prolo Scale. All the
patients safely underwent surgery without severe complications.
Results: At the time of the last follow-up visit, 21 patients (100% of single-level
cases) were content with the result of the surgery. A patient (2-level case) underwent
pedicle screw fixation at a single level due to persistent lower back pain (LBP),
which pseudarthrosis was suspected. During the follow-up period, the patients who
underwent 2-level surgery have multiple complaints. The other patient (female, 2-
level case) suffered from LBP for 24 months. Under conservative treatment, low
back pain improved.
Conclusion: With regard to the preservation of the posterior element for utmost
benefits, a single-level operation has a better prognosis than a two-level operation. In
single level surgery, a PLIF by cages alone produces more satisfactory clinical results
at L3/4 and L4/5 than at L5/S1. |
