An anatomic study investigated the attachment of the nuchal muscles to the spinous process. ⋯ The current study confirmed that C3-C6 laminoplasty in which the C7 spinous process is preserved reduces invasion of the nuchal muscles.

Comparative Study
Differences in standing and forward bending in women with chronic low back or pelvic girdle pain: indications for physical compensation strategies.
This cohort study compares motion characteristics during forward bending of a group of chronic female patients either with low back pain (LBP) or pelvic girdle pain (PGP) and healthy subjects using computer-video analysis. ⋯ BP and PGP patients show specific, consistent, and distinct motion patterns. These motion patterns are assumed to be functional compensation strategies, following altered neuromuscular coordination.

Comparative Study Clinical Trial
Calcium-phosphate and polymethylmethacrylate cement in long-term outcome after kyphoplasty of painful osteoporotic vertebral fractures.
A comparative prospective trial evaluating 3-year outcome. ⋯ CaP cement, e.g., Calcibon, is as effective and safe as conventional PMMA-cement with regard to immediate and sustained pain reduction and improvement of mobility after kyphoplasty of patients with painful osteoporotic vertebral fractures. CaP cement has the potential of being resorbed and replaced by newly formed bone tissue; thus, it seems to be a promising alternative for PMMA also in younger patients with painful vertebral fractures.

Comparative Study
Surgical treatment of severe angular kyphosis with myelopathy: anterior and posterior approach with pedicle screw instrumentation.
Retrospective study. ⋯ Anterior decompression and fusion followed by posterior pedicle screw instrumentation and fusion without correction effectively improved neurologic symptoms and halted progression of kyphotic deformity in cases of severe angular kyphosis with myelopathy.

Comparative Study
Effects of age and comorbidities on complication rates and adverse outcomes after lumbar laminectomy in elderly patients.
This is a retrospective cohort study using the National Inpatient Sample database. ⋯ Elderly patients with comorbidities are at a higher risk for complications and adverse outcome after lumbar spine surgery. The effects of age and comorbidities on patient outcomes have been quantified. This information is critical in counseling elderly patients about the risk of surgery in their age group.
