ABSTRACT
STUDY DESIGN:
A retrospective review of the patients who have a fixation failure of instrumentalion for the spinal fusion in lumbar region.OBJECTIVES:
To assess the incidence and different types of the mechanical failure of fixation and to evaluate their managements and their influences on the progression of a spinal fusion and to the clinical outcomes. SUMMARY OF LITERATURE REVIEW Most of the spine surgeons have been experiencing the mechanical failures after instrumentations for a spinal fusion, eden though the incidence is decreasing with a modification of the implants. Reports on this problem are sporadic in conjunction with the other topics, rarely focusing on their management and their influences on the final outcomes. MATERIALS ANDMETHODS:
338 consecutive patients who had a lateral fusion in the lumbar region with an instrumentation of pedicle screws and rods, mostly with decompression, were reviewed to analyse the fixation failures of instrumentation after surgery.RESULTS:
There were 26 patients (7.7%) who had the fixation failures of instrumentation, in terms of loosening around the pedicle screws in 18 patients (5.3%), the breakage of the pedicle screws in fide patients (1.5%), and the migration of a rod in three patients (0.9%). They were managed by prolonged use of brace and ergonomic back cares. Even with the fixation failures, 19 patients (73.1%) disclosed solid union uneventfully, but one patient had re-operation to obtain solid fusion. The final outcomes were satisfactory in 22 patients (84.6%), including four of six patients who had pseudoarthrosis.CONCLUSIONS:
The fixation failure of instrumentation after a spinal fusion in lumbar region was not rare, but the progression of a spinal fusion usually quite well achieved and the final outcomes were not so bad, even with the implant failures and pseudoarthrosi s. Except for the persistently symptomatic pseudoarthrosis, only a prolonged use of brace and the ergonomic back cares are recommended for symptomatic patients.
