Summary
Granuloma formation can occur after cervical total disc arthroplasty (TDA), or artificial disc replacement. This case highlights nylon thread extrusion from a TDA prosthesis causing a granulomatous reaction, a rare complication.
Area of Science:
- Spine surgery
- Biomaterials science
- Pathology
Background:
- Cervical total disc arthroplasty (TDA) is an alternative to anterior cervical discectomy and fusion for degenerative cervical spine disease.
- TDA aims to preserve motion and reduce adjacent segment degeneration.
- Granuloma formation following cervical TDA is exceptionally rare.
Observation:
- A patient developed recurrent cervicalgia two years after a double-level cervical TDA.
- Cervical MRI suggested granulomatous formation on the C6-C7 prosthesis.
- Surgical removal revealed prosthesis rupture with nylon thread extrusion.
Findings:
- Histopathology confirmed a giant cell granulomatous reaction to extruded nylon threads.
- This complication has been rarely reported following lumbar and cervical TDA.
- This represents the third reported case of granulomatous reaction to nylon extrusion after cervical TDA.
Implications:
- Nylon extrusion from TDA prostheses can lead to rare but significant granulomatous complications.
- This case underscores the importance of material integrity in cervical TDA.
- Further research into long-term biomaterial behavior in TDA is warranted.

Determining Order of Reaction
62.0K
Rate laws describe the relationship between the rate of a chemical reaction and the concentration of its reactants. In a rate law, the rate constant k and the reaction orders are determined experimentally by observing how the rate of reaction changes as the concentrations of the reactants are changed. A common experimental approach to the determination of rate laws is the method of initial rates. This method involves measuring reaction rates for multiple experimental trials carried out using...

Precipitation Reactions
65.4K
In a precipitation reaction, aqueous solutions of soluble salts react to give an insoluble ionic compound – the precipitate. The reaction occurs when oppositely charged ions in solution overcome their attraction for water and bind to each other, forming a precipitate that separates out from the solution. Since such reactions involve the exchange of ions between ionic compounds in aqueous solution, they are also referred to as double displacement, double replacement, exchange reactions, or...

Leveling Effect
1.4K
In acid-base chemistry, the leveling effect refers to the limitation imposed by the solvent on the strength of acids and bases in solution. When a base stronger than the solvent's conjugate base is used, it deprotonates the solvent until the base is entirely consumed, making it ineffective against weaker acids. Conversely, an acid stronger than the solvent's conjugate acid protonates the solvent until the acid is depleted, rendering it ineffective against weaker bases. Essentially, the...

Reaction Stoichiometry
77.9K
A balanced chemical equation provides a great deal of information in a very succinct format. Chemical formulas provide the identities of the reactants and products involved in the chemical change, allowing classification of the reaction. Coefficients provide the relative numbers of these chemical species, allowing a quantitative assessment of the relationships between the amounts of substances consumed and produced by the reaction. These quantitative relationships are known as the reaction’s...

Chemical Reactions
95.7K
A chemical reaction is a process by which the bonds in the atoms of substances are rearranged to generate new substances. Matter cannot be created or destroyed in a chemical reaction—the same type and number of atoms that make up the reactants are still present in the products. Merely, the rearrangement of chemical bonds produces new compounds.

Fixing Double-strand Breaks
14.7K
The double-stranded structure of DNA has two major advantages. First, it serves as a safe repository of genetic information where one strand serves as the back-up in case the other strand is damaged. Second, the double-helical structure can be wrapped around proteins called histones to form nucleosomes, which can then be tightly wound to form chromosomes. This way, DNA chains up to 2 inches long can be contained within microscopic structures in a cell. A double-stranded break not only damages...
