Retrospective cohort analysis. ⋯ Although all patients typically present with a similar functional status, patients with intramedullary lesions are more unlikely to improve after surgical resection and derive less of a benefit compared with those with intradural extramedullary and vertebral hemangiomas.
-
Retrospective observational cohort analysis of administrative claims. ⋯ Readmission rates for spinal stenosis decompression were approximately 8% to 10% per year. Fusion at the index procedure did not protect against subsequent readmission. Large databases can inform choice of surgical options by focusing examination on indications for surgery and reasons for readmission. Fusion along with decompression does not seem to impact readmission rates.
-
A prospective study. ⋯ Without radiation shielding, a surgeon performing 291 PELDs annually would be exposed to the maximum allowable radiation dose. Given the measurable lifetime radiation hazards to the surgeon, the use of adequate protective equipment is essential to reducing exposure during PELD.

Case Reports
Somatosensory-evoked potential monitoring detects iliac artery occlusion during posterior spinal fusion.
Report of a rare case of iliac artery occlusion occurring during posterior spinal surgery. ⋯ It is feasible to assume that continuous and direct pressure on the inguinal region during surgery on Jackson table was the primary cause of the iliac artery occlusion, particularly in these patients with known peripheral vascular disease. Early recognition and prompt vascular intervention can prevent serious sequelae.
