2024年7月24日 · The primary function of vertebral pedicles is to protect the spinal cord and serve as anchors for muscles and ligaments. They also provide the structure necessary to support the weight and movement of the body.

2020年4月25日 · The posterior entrance of the pedicle lies at the junction of the superior articular facet, the transverse process and the lamina; its exact position is variable according to the vertebral level. The exact knowledge of the point of entry …

2022年6月6日 · The pedicle is a short projection of bone that comes directly off the back of the vertebral body. The pedicle lies between the back of the vertebral body and the transverse process. There are two pedicles per vertebra, one on each side.

The region between the transverse process and the vertebral body is called the pedicle. The vertebrae are joined by facet joints (zygapophyseal joints) , which are covered by articulating cartilage to provide smooth movements between the joint surfaces.

2017年3月7日 · The lumbar vertebral bodies are thick and wide, with short pedicles and laminae. The inferior articular processes extend inferiorly from the undersurface of each lamina, while the superior articular processes extend superiorly from the junction of the laminae and pedicles.

2019年12月17日 · The pedicle is an essential element in spinal instrumentation as it provides a strong anchorage for osteosynthesis that allows a satisfactory correction of spinal deformities as well as a rigid stabilization of traumatic, degenerative, infectious, iatrogenic or tumoural instability.

2023年9月12日 · It consists of two pedicles and two laminae. The pedicles contain vertebral notches (superior, inferior) which form intervertebral foramina. These facilitate the passage of spinal nerves from the spinal cord. The pedicles, laminae, and body of each vertebra form a cavity (vertebral foramen).

The intervertebral discs, along with the laminae, pedicles and articular processes of adjacent vertebrae, create a space through which spinal nerves exit.

The pedicles are two short, thick processes, which project dorsally, one on either side, from the superior part of the vertebral body at the junction of its posterior and lateral surfaces. They connect the body of the spinal vertebra to the arch.

Understanding the morphometry of the pedicle and the anatomy of adjacent neural structures should help decrease the risk of postoperative complications.
