Radiological Outcome of Short Segment Posterior Instrumentation …
The short segment posterior instrumentation and fusion is the current trend as it can reduce the blood loss, preserving segmental motion with an acceptable anatomic and functional outcome [5,6,7,8,9,10,11,12,13]. However, there are also reports of high percentages of instrumentation failure [14,15].
