Review Case Reports
Unstable pathological fracture of the odontoid process caused by Langerhans cell histiocytosis.
A case report and literature review. ⋯ Immobilization and systemic chemotherapy with close observation are adequate for the management of patients despite the unstable pathological fracture of the odontoid process.

Review Case Reports
Cervical myelopathy after cervical total disc arthroplasty: case report and literature review.
Case report and literature review. ⋯ On the basis of presented cases and other reports, the surgical goals in these patients were prioritized as follows: (1) safe and adequate neurological decompression and (2) establishment and maintenance of cervical sagittal balance. Moreover, a criterion for selecting patients undergoing CTDA needs to be established in order to reduce the occurrence of neurological complications associated with the procedure.

Multicenter Study
Postoperative segmental motion of the unfused spine distal to the fusion in 100 patients with adolescent idiopathic scoliosis.
A cross-sectional study. ⋯ In a group of postoperative patients with adolescent idiopathic scoliosis, evaluation of the distal unfused intervertebral motion showed that preservation of vertebral motion segments allowed greater distribution of functional motion across more levels. With each distal fusion level, motion was significantly increased at the L2-L3, L3-L4, and L4-L5 segmental levels in lateral bending. The relationship between the increased motion and subsequent disc degeneration with a more distal fusion is unknown, but suspected.

We reviewed existing methods for identifying patients with neck and back pain in administrative data. We compared these methods using data from the Department of Veterans Affairs. ⋯ Gaps are evident in existing methods and a new framework to identify patients with neck pain and back pain in administrative data is proposed.

Review
Nonoperative treatment of lumbar spinal stenosis with neurogenic claudication: a systematic review.
Systematic review. ⋯ Moderate- and high-GRADE evidence for nonoperative treatment is lacking and thus prohibiting recommendations to guide clinical practice. Given the expected exponential rise in the prevalence of lumbar spinal stenosis with neurogenic claudication, large high-quality trials are urgently needed.
