Summary

Researchers at Assiut University are measuring the shape and size of the sub axial cervical spine pedicle in Egyptian adults using CT scans. The goal is to see whether cervical pedicle screws can be placed safely in this population. The study includes 80 people aged 16 to 65 who need a cervical spine CT for unrelated reasons. People with spine abnormalities, injuries, or certain conditions are excluded.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Cervical pedicle screw
What this could lead to
If the measurements show enough space, it could support safer use of cervical pedicle screws in Egyptian patients.
What could go wrong
This is an observational study, not a treatment test. Results may not apply to people with spine conditions or injuries.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Sample size was calculated using Epi- Info7. According to results of previous study (put ref.) , the pullout strength failed by fracture of pedicle screw in 40% of patients undergoing cervical spine CT. Based on this percentage, confidence limits of 7% and a confidence level of 80%, the sample needed for the study was estimated to be about 80 patients.

Ages
