Summary
Understanding cervicothoracic junction anatomy is crucial for spinal stabilization. This study details predictable bony and soft tissue changes from C5-T3, aiding surgical planning and reducing risks.
Area of Science:
- Spinal anatomy
- Cervicothoracic junction
- Surgical anatomy
Background:
- Posterior spinal stabilization carries risks of soft tissue damage.
- Understanding cervicothoracic junction anatomy is essential for safe surgical procedures.
Purpose of the Study:
- To provide reference data on anatomic variations within the cervicothoracic junction.
- To characterize intrasegmental and intersegmental gradients of anatomic variation.
Main Methods:
- Analysis of 324 cross-sectional spinal segments from nine human spines.
- Characterization of bony and soft tissue relationships in the cervicothoracic junction.
Main Results:
- Predictable cranial-to-caudal alterations in bone and soft tissue anatomy were observed.
- Neural and vascular structures anterior/lateral to bony landmarks decrease in frequency.
- Vertebral dimensions increase from C5-T3, with noted exceptions in pedicle dimensions at C7-T1.
Conclusions:
- Anatomic changes in the cervicothoracic junction are consistent and predictable.
- Recognizing these predictable changes improves understanding of clinical implications.
- This data aids in safer surgical approaches to the cervicothoracic spine.
