Short-segment cement-augmented fixation in open separation surgery of metastatic epidural spinal cord compression: initial experience

چکیده
OBJECTIVE High-grade metastatic epidural spinal cord compression from radioresistant tumor histologies is often treated with separation surgery and adjuvant stereotactic body radiation therapy. Historically, long-segment fixation performed during posterior transpedicular of a minimum 2 levels superior inferior to the decompression. Previous experience minimal access techniques percutaneous stabilization have highlighted reduced morbidity as an advantage use shorter constructs. Cement augmentation pedicle screws attractive option for enhanced while performing fixation. Herein, authors describe their initial open using short-segment cement-augmented screw reconstruction. METHODS The retrospective chart review patients undergoing (i.e., nonpercutaneous, surgery) high-grade at single adjacent decompression level(s). Patient demographics, treatment data, operative complications, short-term radiographic outcomes were evaluated. RESULTS Overall, 44 met inclusion criteria follow-up mean 8.5 months. Involved included 19 thoracic, 5 thoracolumbar, 20 lumbar. through fenestrated was in 30 patients, vertebroplasty-type approach used remaining 14 augment purchase. One (2%) patient required revision hardware complication. Three (7%) nonoperative complications occurred, including 1 pathologic fracture index level causing progressive kyphosis incidences haloing around screw. There wound that managed conservatively without intervention. No cement-related occurred. CONCLUSIONS Open posterolateral utilizing viable alternative instrumentation reconstruction following spine tumors. Studies longer are needed determine rates delayed durability these outcomes.

Metastatic spinal cord compression is a devastating complication of cancer. Patients may often require high doses of opioids that may cause side effects, myoclonus being one such. A 63-year-old male suffering from malignant spinal cord compression was admitted to our institution. The primary team managed him conservatively with pharmacotherapy with no relief of pain, and he experienced myoclonu...

متن کاملMetastatic Spinal Cord Compression
According to recent Canadian statistics, an estimated 186,400 new cases of cancer and 75,700 deaths from cancer are expected in Canada in 20121. In general, between 40% and 70% of patients with advanced solid tumours such as those of breast, prostate, and lung will develop bone metastases2. The spine is the most common site for bone metastasis, affecting up to 30% of cancer patients3. Overall, ...
