[Lumbopelvic stabilization for bilateral lumbosacral instabilities: indications and techniques].
BACKGROUND
Bilateral lumbopelvic instabilities are rare; for the affected patients, however, they mean a severe reduction in quality of life. Optimal results can only be achieved with a well-adapted therapy algorithm that balances surgery and non-surgical procedures.


OBJECTIVE
The present article addresses the indications, strategy, and techniques of bilateral lumbopelvic fixation in the operative treatment of bilateral lumbopelvic injuries and review of the literature and personal experience.


RESULTS
The overall incidence of lumbosacral instabilities is low and mainly caused by high energy trauma, osteoporotic insuffiencies (e.g., primarily or secondary after long segment lumbar instrumentation), and tumors. Dramatic soft tissue injuries can occur in addition to hidden neurological impairments, and therefore it is important to diagnose and evaluate all concomitant comorbidities. The keys to success are gaining stability in the lumbosacral junction possibly combined with neuronal decompression and meaningful coordination of all disciplines, certainly challenged by finding the correct moment for surgery which is between 2 days and 2 weeks. Based on the superficial anatomy of the bony structures in the lumbosacral junction, the surgical approach has to match the pathology and should be tissue saving.


CONCLUSIONS
Treatment of bilateral lumbopelvic instabilities requires an accurate examination, sophisticated therapy protocol, and a multidisciplinary approach. Surgery with a bilateral lumbopelvic fixation combined with neuronal decompression is an adequate treatment that creates early bony stability, thus, promising functional weight-bearing mobilization.
