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.

The loads acting on a vertebral body replacement (VBR) were measured in vivo. ⋯ High forces may act on a VBR especially in the first postoperative month. Flexion of the upper body and going upstairs cause high implant loads and should be avoided in the first few months after stabilizing the spine.

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.

Comparative Study
The cultural adaptation, reliability and validity of neck disability index in patients with neck pain: a Turkish version study.
The aim of this study was to conduct the cross-cultural adaptation of Neck Disability Index (NDI) and investigate the validity and reliability of Turkish version in patients with neck pain. ⋯ The Turkish version of NDI was found to be a valid and reliable method of measurement for evaluating disability, caused by problems of the neck region as it is easy to comprehend by the patients and the time needed to apply is short in clinics.
