Percutaneous veebroplasty is not done for:

**Percutaneous Vertebroplasty**

**Core Concept**
Percutaneous vertebroplasty is a minimally invasive procedure used to treat vertebral compression fractures by injecting bone cement into the affected vertebra. This procedure aims to stabilize the spine, alleviate pain, and improve quality of life for patients with vertebral fractures.

**Why the Correct Answer is Right**
The correct answer is D. **Osteoporotic compression fractures** are a common indication for percutaneous vertebroplasty. However, the procedure is not typically performed for patients with **infectious spondylodiscitis** (D). This is because the introduction of bone cement into an infected disc or vertebra can exacerbate the infection, leading to further complications.

**Why Each Wrong Option is Incorrect**
* **Option A:** Traumatic fractures may be treated with percutaneous vertebroplasty, especially if they are unstable or not responding to conservative management.
* **Option B:** Osteolytic lesions, such as those caused by multiple myeloma, may be treated with percutaneous vertebroplasty to stabilize the bone and alleviate pain.
* **Option C:** Degenerative disc disease is not typically treated with percutaneous vertebroplasty, as the procedure is more focused on stabilizing the spine in cases of vertebral fractures or osteolytic lesions.

**Clinical Pearl / High-Yield Fact**
Percutaneous vertebroplasty is a safe and effective procedure for treating vertebral compression fractures, but it should be performed only in patients with a clear indication and under the guidance of an experienced interventional radiologist or orthopedic surgeon.

**Correct Answer:** D. Infectious spondylodiscitis.
