BACKGROUND: osteoporotic elderly patients with lumbar spine problems needing
stabilzation are more likely to be encountered with recently and constitute a major
concern to the spine surgeon due to the increased rate of mechanical failure at the
osteoporotic spine-implant interface
AIM OF THE STUDY: we tried to evaluate the validity of CBT to stabilize the lumbar
spine when indicated in osteoporotic patients from Jnuary 2018 till December 2021 at
the Neurosurgery department Benha University Hospital.
PATIENTS AND METHODS: a retrospective study for the medical reports of all
patients operated upon by the cortical bone trajectory technique (CBT) to stabilize the
lumbosacral spine in osteoporotic patientsfrom Jnuary 2018 till December 2021 at the
Neurosurgery department Benha University Hospital.
RESULTS: 20 osteoporotic patients were admitted at the Neurosurgery department
Benha University Hospital from Jnuary 2018 till December 2021 with the diagnosis pf
lumbar instability that required fixation due to lithesis in 10 patients, recurrent disc
herniation in 8 patients and foraminal stenosis in 2 patients. After 24 month nean
follow up period there were decrease in VAS for low back pain and fusion occurred in
90 % of patients
CONCLUSIONS: Cortical bone trajectory screws are valid to stabilize the lumbar
spine in osteoporotic patients with lumbar instability due to different pathologies.
