Journal of Neurosurgery. Spine
|December 23, 2017
Summary
A novel interspinous process screw/rod construct provided stable temporary fixation for a thoracolumbar spine injury. This technique allowed for safe placement of traditional instrumentation, preventing further spinal cord damage.
Area of Science:
- Orthopedic Surgery
- Spinal Surgery
- Neurosurgery
Background:
- Operative management of thoracolumbar spine injuries often requires temporary fixation for unstable segments.
- Traditional fixation methods may pose risks during the management of complex injuries.
Observation:
- A patient with a ligamentous thoracolumbar flexion-distraction injury presented with spinal instability.
- The need for temporizing fixation was identified during the operative management.
Findings:
- A novel interspinous process screw/rod construct was utilized for temporary fixation.
- The construct demonstrated stability, enabling the subsequent placement of traditional posterior instrumentation and fusion.
- This method successfully prevented secondary injury to the spinal cord.
Implications:
- This technique offers a potentially safer approach to managing unstable thoracolumbar spine injuries.
- The described construct may be a valuable addition to the armamentarium for spinal surgeons.
- Further research is warranted to evaluate the long-term efficacy and broader applicability of this novel fixation method.

Protons and neutrons, collectively called nucleons, are packed together tightly in a nucleus. With a radius of about 10−15 meters, a nucleus is quite small compared to the radius of the entire atom, which is about 10−10 meters. Nuclei are extremely dense compared to bulk matter, averaging 1.8 × 1014 grams per cubic centimeter. If the earth’s density were equal to the average nuclear density, the earth’s radius would be only about 200 meters.

Intact DNA strands can be found in fossils, while scientists sometimes struggle to keep RNA intact under laboratory conditions. The structural variations between RNA and DNA underlie the differences in their stability and longevity. Because DNA is double-stranded, it is inherently more stable. The single-stranded structure of RNA is less stable but also more flexible and can form weak internal bonds. Additionally, most RNAs in the cell are relatively short, while DNA can be up to 250 million...

The time response of a linear time-invariant (LTI) system can be divided into transient and steady-state responses. The transient response represents the system's initial reaction to a change in input and diminishes to zero over time. In contrast, the steady-state response is the behavior that persists after the transient effects have faded.
The stability of an LTI system is determined by the roots of its characteristic equation, known as poles. A system is stable if it produces a bounded...

6.7K
The structure and stability of mRNA molecules regulates gene expression, as mRNAs are a key step in the pathway from gene to protein. In eukaryotes, the half-life of mRNA varies from a few minutes up to several days. mRNA stability is essential in growth and development. The absence of the proteins regulating its stability, such as tristetraprolin in mice, can cause systemic issues, including bone marrow overgrowth, inflammation, and autoimmunity.

In mechanical engineering, the stability of systems under various forces is critical for designing durable and efficient structures. One fundamental way to explore these concepts is by analyzing systems like two rods connected at a pivot point, O, with a torsional spring of spring constant k at the pivot point. This system is similar in appearance to a scissor jack used to change tires on a car. In this case, the arms of the linkage (equivalent to the rods in this system) are entirely vertical,...

The transfer function is a fundamental concept representing the ratio of two polynomials. The numerator and denominator encapsulate the system's dynamics. The zeros and poles of this transfer function are critical in determining the system's behavior and stability.
Simple poles are unique roots of the denominator polynomial. Each simple pole corresponds to a distinct solution to the system's characteristic equation, typically resulting in exponential decay terms in the system's...
