Predisposing factor for adjacent-segment failure following lumbar fixation for degenerative instability
Mohamed Shaban
Cairo University, Egypt
Aim:
Adjacent-segment failure is a well-known risk of lumbar fixation. The aim of this retrospective study was to identify risk factors
for next-segment failure in lumbar fixation for degenerative instability.
Method:
We retrospectively evaluated 122 patients who underwent of lumbar fixation for degenerative instability from 2011 to 2014
in Faculty of Medicine, Cairo University. All procedures were performed by a single surgeon. The patients with next-segment failure
underwent neurological assessment, radiographic studies and sequential follow-up examinations. The mean follow-up period for this
group was 30 months.
Results:
33 patients of 122 fusion procedures were performed in women who were postmenopausal. A total of 19 patients of 125
patients developed symptomatic next-segment degeneration at a previously asymptomatic level; 15 were postmenopausal women. All
women were postmenopausal, and 50% received bisphosphonate drugs and calcium supplementation preoperatively for osteopenia.
20% of all patients with next-segment failure were cigarette smokers. Next-segment diseases included spondylolisthesis (52%), spinal
canal stenosis due to disc herniation and/or facet hypertrophy (33%), stress fracture (12%), and scoliosis (3%). Patients may have
more than one degenerative process at the next segment.
Conclusions:
Postmenopausal women show the highest risk of adjacent-segment failure for patients in whom lumbar fusion with
rigid instrumentation is performed to treat degenerative instability.
