Summary
Lumbar retrolisthesis is linked to increased spinal kyphosis and poorer spinopelvic alignment. Lower lumbar retrolisthesis correlates with worse alignment and health-related quality of life.
Area of Science:
- Orthopedics
- Radiology
- Geriatrics
Background:
- Lumbar retrolisthesis pathology requires further elucidation.
- Understanding its impact on spinal alignment and quality of life is crucial for older adults.
Purpose of the Study:
- To investigate the role of lumbar retrolisthesis in spinopelvic alignment.
- To assess the impact of lumbar retrolisthesis on health-related quality of life (HRQOL) in individuals over 50.
Main Methods:
- A large cohort study included 639 volunteers (average age 73).
- Radiographic measurements included sagittal vertical axis (SVA), thoracic kyphosis (maxTK), lumbar lordosis (LL), pelvic incidence (PI), and pelvic tilt (PT).
- Health-related quality of life was assessed using the Oswestry Disability Index (ODI).
Main Results:
- 41% of subjects had lumbar retrolisthesis (R(+)).
- The R(+) group exhibited greater SVA, maxTK, and PI-LL, with smaller LL and PI compared to the R(-) group.
- Subjects with lower lumbar retrolisthesis (inferior group) showed significantly worse spinopelvic alignment and ODI scores.
Conclusions:
- Lumbar retrolisthesis is associated with increased spinal kyphosis and poorer spinopelvic alignment.
- Lower lumbar retrolisthesis is linked to worse spinopelvic alignment and reduced HRQOL compared to upper or multiple retrolisthesis.

7.1K
In animals, gender is determined by the number and type of sex chromosome. For example, human females have two X chromosomes, and males have one X and one Y chromosome, whereas C.elegans with one X chromosome is a male, and the one with two X chromosomes is a hermaphrodite.
In addition to sexual development, the X chromosome has genes involved in autosomal functions such as brain development and the immune system. Therefore, males and females with distinct numbers of X chromosomes will...

01:28Compensation Mechanisms
2.0K
The human body employs intricate mechanisms to counteract changes in blood pH, preventing conditions like acidosis (pH < 7.35) and alkalosis (pH > 7.45). These compensatory responses aim to restore normal arterial blood pH by engaging respiratory or renal systems, depending on the source of the imbalance.
Respiratory Compensation
This mechanism addresses metabolic-induced pH imbalances by adjusting breathing rates. Respiratory compensation begins within minutes of detecting a pH...

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.

01:54The Spinal Cord
31.6K
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.

01:10Spinal Cord: Information Processing
3.3K
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...

01:21Spinal Nerves: Plexus II
2.2K
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...
