About iliolumbar ligament, which of the following statements is false (2018)
**Core Concept**
Iliolumbar ligament is a strong, thick ligament that connects the ilium to the transverse process of the first or second lumbar vertebra (L1 or L2). It plays a crucial role in stabilizing the lumbar spine, particularly during rotational movements.
**Why the Correct Answer is Right**
The correct answer is related to the function of the iliolumbar ligament, which primarily acts as a stabilizer of the lumbar spine by limiting excessive motion between the ilium and the transverse process of the lumbar vertebrae. This ligament is not primarily involved in the movement or rotation of the lumbar spine.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because the iliolumbar ligament is indeed attached to the transverse process of the lumbar vertebrae (L1 or L2). It is not attached to the spinous process.
**Option B:** This option is incorrect because the iliolumbar ligament is indeed involved in stabilizing the lumbar spine and limiting excessive motion between the ilium and the lumbar vertebrae.
**Option C:** This option is incorrect because the iliolumbar ligament is primarily involved in stabilizing the lumbar spine, not in the movement or rotation of the lumbar spine.
**Clinical Pearl / High-Yield Fact**
The iliolumbar ligament is often injured in sports that involve twisting or rotational movements of the lumbar spine, such as golf, tennis, or hockey. Injuries to this ligament can lead to chronic back pain and instability.
**Correct Answer:** A.
