Randomized Controlled Trial
How do low back pain patients conceptualize their expectations regarding treatment? Content analysis of interviews.
The purpose of this study was to gain insight into how low back pain (LBP) patients conceptualize the construct of expectations regarding treatment. ⋯ This study showed that LBP patients' expectations for treatment are multifaceted. Current measurement instruments do not cover all domains and subdomains of expectations. Therefore, we recommend the development of new or improved measures that make a distinction between value and probability expectations and assess process and/or outcome expectations covering multiple subdomains. Some of the influencing factors found in this study may be useful targets for altering patients' treatment expectations and improving health outcomes.

Randomized Controlled Trial
Tranexamic acid reduces postoperative blood loss of degenerative lumbar instability with stenosis in posterior approach lumbar surgery: a randomized controlled trial.
This study is randomized controlled trial. ⋯ Preoperative single-dose TXA can significantly reduce postoperative blood loss in posterior approach lumbar surgery, and there were no significant side effects.

Randomized Controlled Trial
The effect of timing of rehabilitation on physical performance after lumbar spinal fusion: a randomized clinical study.
The number of patients undergoing lumbar spinal fusion procedures (LSF) has risen in recent years, but only few studies have examined different rehabilitation strategies for this patient group. ⋯ No difference was found in the effect of initiating rehabilitation either 6 or 12 weeks after LSF on the patients' physical performance in terms of fitness and walking distance. The 6MWT showed fair to moderate correlation to the questionnaire-based outcome measures. The AF-test showed no significant independent value, and we question its use in LSF patients.

Randomized Controlled Trial Comparative Study
Comparison of titanium and polyetheretherketone (PEEK) cages in the surgical treatment of multilevel cervical spondylotic myelopathy: a prospective, randomized, control study with over 7-year follow-up.
Anterior cervical discectomy and fusion (ACDF) with titanium- or polyetheretherketone (PEEK)-cage reconstruction is widely used in the treatment of cervical spondylotic myelopathy (CSM). This study was to compare outcomes of titanium and PEEK cages in the treatment of multilevel CSM. ⋯ In surgical treatment of multilevel CSM, PEEK cage is superior to titanium cage in maintenance of intervertebral height and cervical lordosis, resulting in better clinical outcomes in the long-term follow-up.

Randomized Controlled Trial
Predictors for long-term disability in women with persistent postpartum pelvic girdle pain.
The majority of prognostic studies on postpartum lumbopelvic pain have investigated factors during pregnancy. Since the majority of women recover within the first few months of delivery, it is unknown if the same predictors are valid for long-term consequences. It is also important to investigate predictors within subgroups of patients with pregnancy-related lumbopelvic pain due to their different clinical courses. The aim of this study was to identify predictors for disability 15 months postpartum in women with persistent postpartum pelvic girdle pain (PGP). ⋯ Age, muscle function and disability seem to influence the long-term outcome on disability in women with persistent postpartum PGP. It may be important to consider the possibility of different variables impact on each other when predicting long-term disability. In addition, further studies are needed to investigate the impact of interaction effects on long-term consequences in women with persistent postpartum PGP.
