We investigated the 30-day complication incidence and 1-year radiographic correction in obese patients undergoing surgical treatment of cervical deformity. ⋯ Obese patients had a 5 times greater odds of developing infections after surgery for adult cervical deformity. Obese patients also showed significantly greater pelvic anteversion after cervical correction.

Case Reports
Retropharyngeal granulation: A delayed complication of anterior cervical discectomy and fusion in C2-3.
A 26-year-old man presented with acute quadriparesis owing to a traffic accident. A computed tomography scan revealed a hangman fracture and locking of the left facet joint at C2-3. Magnetic resonance imaging showed a high signal change of the spinal cord on T2-weighted image and hemorrhage in the C2-3 level. ⋯ Retropharyngeal granulation can occur as a late complication associated with plate fixation after anterior cervical diskectomy and fusion. Recurrent retropharyngeal wall granulation caused by plate irritation might only be resolved after plate and screw removal.

Subclavian steal phenomenon can cause retrograde flow through the ipsilateral vertebral artery as a result of atherosclerosis of the subclavian artery. Clinically this can present as intermittent vertebrobasilar ischemia or claudication of the affected extremity, but rarely it poses a serious risk of neurologic morbidity or mortality. Aneurysm formation at the vertebrobasilar junction is rare but may occur as a sequela of increased flow through 1 vertebral artery, as occurs in subclavian steal syndrome. Here, we present a rare case of subarachnoid hemorrhage from a vertebrobasilar junction aneurysm related to subclavian steal syndrome.

Superior cluneal nerve entrapment neuropathy is one cause of low back pain often referred to as "pseudo sciatica." Studies have found that the superior cluneal nerve can arise variably from T11 to L5. The osteofibrous tunnels formed by a groove on the iliac crest might compress the superior cluneal nerve. Therefore, the purpose of this study was to investigate the origin of the superior cluneal nerve and its course through such bony grooves. ⋯ These results could help identify such bony grooves and better understand low back pain and its related anatomy.

To analyze the plasma cell-free DNA (Cf-DNA) in glioma patients with high throughout sequencing for a novel non-invasive method for the early diagnosis and management of glioma. ⋯ There were some cancer-related somatic mutations in the Cf-DNA of glioma patients, but no identical mutations were found in the paired solid tumors. Therefore, plasma Cf-DNA mutations may not be a suitable marker for the detection of glioma.
