Summary
Cervical pedicle screws offer a safe surgical option for cervical spondylotic myelopathy. Preoperative MRI is crucial for identifying individual safe spaces and avoiding spinal cord injury.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Radiology
Context:
- Cervical spondylotic myelopathy (CSM) is a degenerative condition affecting the cervical spine.
- Surgical intervention is often required to decompress the spinal cord.
- Cervical pedicle screw fixation is a common surgical technique.
Purpose:
- To investigate the anatomical relationship between the cervical pedicle and the spinal cord.
- To determine the safety margins for pedicle screw placement in CSM patients.
- To assess if spinal cord compression influences these anatomical parameters.
Summary:
- This study measured the distance (LH/RH) and angle (LSA/RSA) between the cervical pedicle and spinal cord in 105 CSM patients using MRI.
- No statistically significant differences were found in these parameters between compressed and non-compressed spinal cord segments.
- Results indicate a consistent safety space, though with individual variations.
Impact:
- Highlights the importance of preoperative MRI for precise surgical planning.
- Emphasizes the need for individualized surgical approaches to prevent spinal cord injury.
- Provides valuable anatomical data for neurosurgeons and orthopedic surgeons performing cervical spine surgery.

01:54The Spinal Cord
32.8K
The spinal cord is the body’s major nerve tract of the central nervous system, communicating afferent sensory information from the periphery to the brain and efferent motor information from the brain to the body. The human spinal cord extends from the hole at the base of the skull, or foramen magnum, to the level of the first or second lumbar vertebra.

6.2K
The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.

The spinal cord resides within the protective confines of the vertebral column. It is the main pathway for information traveling between the brain and the body. It plays a fundamental role in nearly all bodily functions, from simple reflexes to complex motor movements. The spinal cord begins at the medulla oblongata at the base of the brainstem and extends downward, terminating at the conus medullaris near the first and second lumbar vertebrae. The spinal cord's length in adults is...

01:16Vertebral Column: Regions and Curvature
11.6K
The vertebral column or spine is a flexible column that supports the head, neck, and body and allows for their movements. It also protects the spinal cord.
Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form...

The spinal cord, a critical component of the central nervous system, extends from the base of the brainstem to the lumbar region of the vertebral column. It is essential for maintaining physical stability and facilitating communication between the brain and peripheral parts of the body.
