It has been shown in literature that a
fibrous tissue called "halo sign" in the radiological terminology can
develop around the transpedicular screws implanted incompletely and/or incorrectly,
which appears after movement of the screw in the cancellous bone. In this
retrospective clinical study, 141 patients who underwent posterior spinal
instrumentation for thoracic, lumbar or thoracolumbar vertebrae were evaluated
using computed tomography (CT) and direct X-rays images for "halo
sign" formation which refers in probable failure of spinal
instrumentation. Hospital records included in the year 2014-2018 were examined
and adult patients who were performed lumbar, thoracal, and thoracolumbar
spinal instrumentation via posterior approach due to reasons such as
"spine fracture", "spondylosis",
"spondylolisthesis" and "intervertebral disc hernia" were
included and evaluated in this study. The age and sex of the patients were
recorded. Spinal X-ray and spinal CT images obtained during the postoperative
follow-up period were examined. Halo sign was seen in 13 patients. Age
(p=0.013), number of instrumented vertebrae (p=0.001) and number of
transpedicular screws (p<0.001) values were different between the patients
with halo sign and patients without halo sign. As a result, it was observed in
this study that the formation of the halo sign in posterior spinal
instrumentation system could develop in proportion to the number of
transpedicular screw and patients' age. It was thought that the halo sign
formation was not connected with the parameters called performed laminectomy,
gender, inserted intervertebral cage, or vertebral region which were inserted
transpedicular screws.
