概括
在成年脊柱形手术中,杆痕迹长度在纠正后显著缩短,特别是在更大的冠状形的情况下. 这表明,避免过长的杆子可以防止诸如近端结节色等并发症.
科学领域:
- 脊柱外科手术 脊柱外科手术
- 整形外科手术 整形外科手术
- 变形纠正 变形纠正 变形纠正
背景情况:
- 准确的棒长度在成年脊柱形 (ASD) 手术中至关重要,以防止诸如近端结节形 (PJK) 等并发症.
- 由于复杂的3D调整,预测杆痕长度 (RTL) 变化在ASD中具有挑战性,与青少年异常学脊椎病 (AIS) 不同.
- 在ASD中,PJK更常见,这增加了适当的棒长选择的重要性.
研究的目的:
- 在成年脊柱形患者的后部正手术前后,量化评估杆痕长度 (RTL) 的变化.
- 评估RTL变化与脊柱对齐校正之间的相关性,包括腰部位和科布角.
主要方法:
- 对30名自闭症患者进行了分阶段侧腰椎体间融合 (LLIF),随后是后部融合的回顾性分析.
- 杆痕迹长度 (RTL) 测量在CT扫描前后后纠正.
- 评估腰部主病 (LL) 和科布角前后纠正.
主要成果:
- 手术后的RTL持续缩短,所有患者平均减少16-17毫米.
- RTL缩短与腰部位 (LL) 纠正 (R=0.51) 和科布角纠正 (R=0.70) 有显著的相关性.
- 在手术前科布角≥10°的患者中,凸侧发生了较大的RTL缩短.
结论:
- 冠状元变形增加,特别是在凸起的侧面,与ASD手术中较大的RTL缩短有关.

Spinal Cord
1.8K
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.

The Spinal Cord
31.7K
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.

Spinal Cord: Information Processing
3.4K
The spinal cord is an integral hub for motor and sensory information that enables the brain to communicate with the peripheral nervous system (PNS). This communication consists of relaying sensory data and transmission of motor commands.
Sensory Information Processing
Sensory information processing begins at the sensory receptors located in the skin and other tissues, which detect somatic sensory stimuli such as touch, temperature, or pain. These receptors function as catalysts, initiating...

Spinal Nerves: Plexus II
2.3K
The plexuses of the lower body include the lumbar, sacral, and coccygeal plexuses, which innervate the abdomen, pelvis, legs, and coccygeal region. These plexuses control the transmission of sensory information and coordinate motor functions of the lower body.
The Lumbar Plexus
The lumbar plexus is situated within the lumbar region of the back and is primarily formed by the first four lumbar spinal nerves (L1 to L4). This plexus extends its branches into several nerves, including the...

Cranial and Spinal Meninges
3.9K
The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...

Spinal Nerves: Anatomy
8.6K
Spinal nerves are pivotal conduits in the nervous system, bridging the central nervous system (CNS) with the peripheral nervous system (PNS). These nerves enable a complex communication network between the brain, spinal cord, and the rest of the body, facilitating sensory input, motor output, and autonomic functions.
