Spine
-
A technical case report of direct surgery for spinal arteriovenous fistulas of the filum terminale. ⋯ Although intraoperative image guidance is certainly not a prerequisite, the concept of safe and minimally invasive surgery makes it indispensable. It can facilitate identification of crucial or important landmarks where anatomic structures may be distorted.
-
Prospective cohort observational study. ⋯ AMDs do not detect modern spinal implants. HHMDs detect all modern posterior spinal implants; this has implications for patient documentation.
-
A case report. ⋯ Delayed anterior spinal artery syndrome after aortic coarctation repair because of anterior spinal artery thrombosis can manifest even 6 months postoperatively. Careful analysis of pre- and postoperative cross-sectional imaging should provide the correct diagnosis. Spinal digital subtraction angiography is probably unnecessary and must be interpreted with caution.

Comparative Study
Does obesity affect outcomes of treatment for lumbar stenosis and degenerative spondylolisthesis? Analysis of the Spine Patient Outcomes Research Trial (SPORT).
Retrospective subgroup analysis of prospectively collected data according to treatment received. ⋯ Obesity does not affect the clinical outcome of operative treatment of SpS. There are higher rates of infection and reoperation and less improvement from baseline in the SF-36 physical function score in obese patients after surgery for DS. Nonoperative treatment may not be as effective in obese patients with SpS or DS.
