Randomized Controlled Trial Multicenter Study Comparative Study
Comparison of adverse events between the Bryan artificial cervical disc and anterior cervical arthrodesis.
Randomized controlled study. ⋯ Bryan cervical disc replacement and anterior cervical fusion are both safe procedures with a low incidence of significant adverse events related to the procedure. Statistically, more serious adverse events and reoperations occurred in the fusion group while a greater number of less serious surgically related events were seen in the investigational group.

A cohort study. ⋯ Women with combined pain were identified to be a target group since they had the most unfavorable course and since the classification of combined pain was found to be a predictor for persistent pain postpartum. Identification of women at risk for persistent pain postpartum seems possible in early pregnancy and requires physical examination and self-reports. Pregnancy had low impact on the course of lumbar pain.

Multicenter Study Comparative Study
Adolescent idiopathic scoliosis patients report increased pain at five years compared with two years after surgical treatment.
A multicenter study of changes in Scoliosis Research Society (SRS) outcome measures after surgical treatment of adolescent idiopathic scoliosis (AIS). ⋯ There was a statistically significant increase in reported pain from 2 to 5 years after surgical treatment; however, the etiology of worsening pain scores could not be elucidated. Given continued patient satisfaction, the clinical relevance of this small reduction remains unknown. Nevertheless, this observation deserves further evaluation and must be considered in relation to the natural history of this disease.

Multicenter Study Comparative Study
Spontaneous lumbar curve correction in selective thoracic fusions of idiopathic scoliosis: a comparison of anterior and posterior approaches.
A retrospective evaluation of adolescent idiopathic scoliosis (AIS) patients treated with selective thoracic instrumentation and fusion. ⋯ Anterior and posterior instrumented fusions performed selectively on the appropriate curves result in equal SLCC when matched by LIV, flexibility of the lumbar curve, and percent thoracic curve correction achieved. This suggests that the observed phenomenon of SLCC after selective thoracic fusion in AIS is independent of surgical approach and can be reliably achieved with either technique.
