Summary
Reconstructing after total sacrectomy is challenging. Combining spinopelvic fixation (SPF), posterior pelvic ring fixation (PPRF), and anterior spinal column fixation (ASCF) improves stability, but biological fixation needs further research.
Area of Science:
- Spine surgery
- Orthopedic reconstruction
- Biomechanical engineering
Background:
- Total sacrectomy presents significant reconstruction challenges.
- Advancements in fixation techniques are crucial for restoring stability.
Purpose of the Study:
- To review the evolution of reconstruction methods after total sacrectomy.
- To guide the selection of optimal reconstruction strategies.
Main Methods:
- Literature search of case reports and biomechanical/finite element studies.
- Summarization of developmental trends and current reconstruction approaches.
Main Results:
- Significant progress in reconstruction concepts and fixation techniques over 30 years.
- Three primary fixation strategies identified: spinopelvic fixation (SPF), posterior pelvic ring fixation (PPRF), and anterior spinal column fixation (ASCF).
- SPF evolved from intrapelvic rods to screw-rod systems; PPRF and ASCF enhance stability.
Conclusions:
- Reconstruction after total sacrectomy remains complex.
- Combining SPF, PPRF, and ASCF is key for mechanical stability.
- Achieving long-term stability through biological fixation is a critical future challenge.

2.3K
An analytical methodology can be divided into four sequential steps: technique, method, procedure, and protocol. A technique is a scientific principle that rationalizes a specific phenomenon through chemical measurements. Adapting a technique for analyzing a sample of interest is termed a method. The procedure outlines the directions for performing the analysis via an analytical method. The protocol is the detailed guidelines on the procedure, which should be strictly followed to obtain the...

01:10Electrical Current
7.2K
Electrical current is defined as the rate at which charge flows. When there is a large current present, such as that used to run a refrigerator, a large amount of charge moves through the wire in a small amount of time. If the current is small, such as that used to operate a handheld calculator, a small amount of charge moves through the circuit over a long period of time. The SI unit for current is the ampere (A), named for the French physicist André-Marie Ampère (1775–1836).

As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

01:10Reconstruction of Signal using Interpolation
737
Signal processing techniques are essential for accurately converting continuous signals to digital formats and vice versa. When a continuous signal is sampled with a period T, the resulting sampled signal exhibits replicas of the original spectrum in the frequency domain, spaced at intervals equal to the sampling frequency. To handle this sampled signal, a zero-order hold method can be applied, which creates a piecewise constant signal by retaining each sample's value until the next...

01:12Total Voids in Concrete
494
Total voids in concrete encompass gel water volume, capillary pores, and entrapped air. Gel water (retained within the cement hydration products) and physically entrapped or adsorbed water are significant for the hydration process. For complete hydration, it's estimated that the space needed for the products of a cubic centimeter of cement doubles. Capillary pores constitute the unoccupied space within the hydrated cement paste, with their size largely influenced by the water-to-cement...

01:21Current Density
5.2K
The total amount of current flowing through one unit value of a cross-sectional area is referred to as current density. If the current flow is uniform, the amount of current flowing through a conductor is the same at all points along the conductor, even if the conductor area varies. The current density consists of the local magnitude and direction of the charge flow, which varies from point to point. Current density is measured in amperes per meter square, and direction is defined as the net...
