Fixation caused by interdiscal block is primarily due to:

• A. Increased flexibility of the disc
• B. Internal derangement of the disc
• C. Inflammation affecting the surrounding tissues
• D. Poor physical conditioning

Answer: (B)

The fixation caused by interdiscal block is primarily due to internal derangement of the disc. When a disc experiences internal derangement, it signifies a disruption in the normal structure and function of the disc, which can lead to impaired movement between vertebrae. This condition may arise from various factors such as degeneration, trauma, or other mechanical issues that cause the disc to lose its natural flexibility and ability to absorb shock. Internal derangement can inhibit the ability of the disc to glide smoothly within the intervertebral space, ultimately leading to a state of fixation, where normal mobility is restricted. This fixation is observed clinically as restricted range of motion and may contribute to pain or discomfort in the affected area. In contrast, increased flexibility of the disc would not result in fixation, but rather in more active movement. Inflammation affecting surrounding tissues could lead to compensatory muscular guarding, but it does not directly cause the disc to become fixated. Poor physical conditioning might contribute to a general increase in musculoskeletal issues, but it does not specifically lead to the fixation associated with internal derangement of the disc. Thus, internal derangement is the primary cause connecting interdiscal block to the phenomenon of fixation in chiropractic practice.
