Multicenter Study
Validation of a minimum outcome core set in the evaluation of patients with back pain.
Prospective study of patients with subacute osteoporotic fracture (SOF) or chronic low back pain (CLBP). ⋯ These findings support the potential usefulness of the Core Set when respondent burden is a major concern. However, subscale scores need to be further tested in other populations before they can be widely recommended.

Randomized Controlled Trial Multicenter Study Comparative Study
Revisability of the CHARITE artificial disc replacement: analysis of 688 patients enrolled in the U.S. IDE study of the CHARITE Artificial Disc.
A prospective, randomized, multicenter, FDA-regulated Investigational Device Exemption clinical trial. ⋯ Lumbar TDR with the CHARITE Artificial Disc did not preclude any further procedures at the index level during primary insertion, with nearly one third being revisable to a new motion-preserving prosthesis and just over two thirds being successfully converted to ALIF and/ or posterior pedicle screw arthrodesis, the original alternative procedure.

Multicenter Study Comparative Study
Can condition-specific health surveys be specific to spine disease? An analysis of the effect of comorbidities on baseline condition-specific and general health survey scores.
This is an observational cross-sectional study of 26,290 patients seen and evaluated in the 25 centers of the National Spine Network. ⋯ Traditional medical comorbidities correlate with both SF-36 (e.g., PCS) general health survey scores as well as disease-specific ODI scores. However, psychosocial comorbidities such as poor self-rated health (SF-1), an active compensation case, and low education level have a higher association than traditional medical comorbidities on these health status measures. The results show that the type of survey (disease-specific e.g., ODI, vs. generic e.g., SF-36) used may be less important than the need to assess and control for psychosocial and medical comorbidities when any patient-reported health survey is used in the spine population.

Multicenter Study
Reliability of a novel classification system for thoracolumbar injuries: the Thoracolumbar Injury Severity Score.
Prospective study of 5 spine surgeons rating 71 clinical cases of thoracolumbar spinal injuries using the Thoracolumbar Injury Severity Score (TLISS) and then re-rating the cases in a different order 1 month later. ⋯ The TLISS has good reliability and compares favorably to other contemporary thoracolumbar fracture classification systems.

Multicenter Study Comparative Study
Emotional health predicts pain and function after fusion: a prospective multicenter study.
Prospective. ⋯ Presurgical emotional status is one significant predictor of pain and function outcomes up to 2 years after fusion. Other significant predictors included workers' compensation status, smoking status, and presurgical pain/function. Studies to identify and intervenewith patients with poorer emotional status will clarify whether presurgical mental health intervention can improve pain and function outcomes after surgery or whether these patients are not candidates for surgery.
