Which forces must be considered when designing an IVD tissue-engineering strategy?

• A. Uniaxial Compression
• B. Biaxial Load
• C. Shear Forces
• D. All of the above

Answer: (D)

When designing an intervertebral disc (IVD) tissue-engineering strategy, it is crucial to consider all the mechanical forces that affect the functionality and health of the IVD. Each type of force plays a vital role in the biomechanical environment of the IVD, which is essential for the design of effective tissue-engineered constructs. Uniaxial compression refers to the forces that compress the disc along a single axis. This type of loading is significant as the IVD primarily sustains compressive loads in the spine, especially during activities such as standing or walking. Understanding uniaxial compression is necessary for mimicking the physiological conditions the IVD experiences in vivo. Biaxial loading involves forces applied simultaneously in two different directions. This type of strain is important for the IVD because it experiences combined loads during various activities, including bending and twisting motions. Incorporating biaxial loading into the design strategies ensures that the engineered tissue can withstand the complex forces encountered in natural motion. Shear forces are critical as they occur when forces are applied in a parallel direction to the surface of the IVD. These forces contribute to the overall stability and function of the IVD by allowing for flexibility and movement between vertebrae. Addressing shear
