Sacral fractures are generally seen together with pelvic ring fractures. They can also develop in isolated form rarely. Instability is observed in these fractures in rates reaching 30%. ⋯ Serious spinopelvic instability can be talked of in sacral fractures accompanied by pelvic fractures, particularly when the anterior and posterior integrity of the pelvic ring is interrupted together. An aggressive stabilization and fixation must be performed without delay.

Case Reports
Intramedullary spinal cord metastasis of renal cell carcinoma 6 years following the nephrectomy.
Intramedullary spinal cord metastasis is an uncommon manifestation of systemic tumor. We present a case of metastatic mass inside the thoracic spinal cord 6 years after nephrectomy because of renal cell carcinoma. ⋯ The case shows that renal cell carcinoma has the possibility of metastasis into spinal cord even several years after nephrectomy. Any symptom of neurological deficit should alert to a possible intramedullary spinal cord metastasis.

To evaluate the feasibility of this novel surgical approach for treatment of cervical discitis and vertebral osteomyelitis. ⋯ The described technique using AI-PMMA offers immediate structural stability and local delivery of high concentration of antibiotics. Use in two patients has demonstrated a cost effective, long-term biomechanically stable construct and infection control.

Piriformis syndrome is a rare neuromuscular disorder that occurs when the piriformis muscle compresses or irritates the sciatic nerve. The treatment of piriformis syndrome includes injections into the piriformis muscle around the sciatic nerve. These invasive approaches have been used with various techniques to increase the safety of the procedure. Computed tomography (CT)-guided injection of the piriformis muscle and the clinical outcome of the patients are discussed. ⋯ CT-guided piriformis injection is a safe and effective method in the treatment of piriformis syndrome.

Dermoid cysts are rare benign congenital tumors comprising 1.1 % of the spinal tumors, with lumbosacral region and cauda equina being the common sites. Many cranial cases with spillage of cyst contents into the subarachnoid space have been reported. ⋯ However, there is no consensus for the treatment of the syrinx cavity. Observation of similar cases would give us more information about treatment options and the progression of these lesions.
