Summary
Patients with spondylolisthesis may have altered spinopelvic parameters. Low sacral slope values might be a compensatory mechanism to maintain balance and reduce pain in these patients.
Area of Science:
- Spine surgery
- Orthopedics
- Radiology
Background:
- Spinopelvic parameters are crucial for maintaining sagittal balance.
- Understanding these parameters is important in conditions like spondylolisthesis.
Purpose of the Study:
- To compare lumbar lordosis and spinopelvic parameters in patients with stage 1-2 spondylolisthesis versus a normal population.
- To highlight the significance of these parameters in sagittal balance.
Main Methods:
- Retrospective analysis of lateral radiographs from 125 patients.
- Comparison of lumbosacral parameters: pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), lumbar lordosis angle (LLA), L5 incidence (L5I), L5 slope (L5S), and sacral table angle (STA).
Main Results:
- No significant sex-based differences were observed in the compared parameters (p > 0.05).
Conclusions:
- Abnormal sagittal spinopelvic parameters are linked to spondylolisthesis development and should be routinely assessed.
- Low sacral slope values in spondylolisthesis patients may represent a compensatory mechanism for pain reduction and sagittal balance maintenance.

Electrochemistry is the science involved in the interconversion of electrical and chemical reactions. Such reactions are called reduction-oxidation, or redox reactions. These important reactions are defined by changes in oxidation states for one or more reactant elements and include a subset of reactions involving the transfer of electrons between reactant species. Electrochemistry as a field has evolved to yield sufficient insights on the fundamental principles of redox chemistry and multiple...

1.2K
The human body gets energy from the three macronutrients: carbohydrates, proteins, and fats. Energy is released when the chemical bonds in the organic compounds present in the food are broken down. The energy content of food is measured in kilocalories (kcal), defined as the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius. This value is determined by measuring the temperature change of the water surrounding a calorimeter after the complete...

The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

01:05Difference from Background: Limit of Detection
8.2K
The limit of detection (LOD) is the smallest amount of analyte that can be distinguished from the background noise. The LOD value corresponds to the concentration at which the analyte signal is three times larger than the standard deviation of the blank signal. Below this value, the analyte signal cannot be differentiated from the background noise. It is calculated by dividing the calibration slope by 3 times the standard deviation of the blank signals.

01:16Electric Potential and Potential Difference
5.6K
Suppose a positive test charge moves away from a positive static charge, then the Coulomb force does positive work, and its electric potential energy decreases. The potential energy per unit charge is defined as the electric potential. The electric potential is independent of the test charge.
When a test charge moves from the initial to the final position, the electric potential difference between those positions is defined as the ratio of the change in the potential energy to the charge on the...

01:29Disorder of Water Balance
2.4K
Water balance disorders are medical conditions that occur when there is a deviation from the body's water volume or osmolarity, disrupting normal homeostasis and leading todehydration, hypotonic hydration, hyperhydration, edema, or water intoxication.
Dehydration
Dehydration occurs when the body loses fluids (particularly water).
Causes:
The major causes of dehydration include excessive sweating, fever, vomiting, diarrhea, and diuresis.
Signs and Symptoms:
Symptoms primarily include intense...
