Randomized Controlled Trial
Posterior lumbar interbody fusion using nonresorbable poly-ether-ether-ketone versus resorbable poly-L-lactide-co-D,L-lactide fusion devices: a prospective, randomized study to assess fusion and clinical outcome.
A prospective randomized clinical study. OBJECTIVE.: To assess fusion, clinical outcome, and complications. ⋯ Our results strongly suggest that PLDLLA cage proffers a lower rate of fusion compared with PEEK cage, and also confirms that the efficacy of PLDLLA cage in enhancing interbody spinal fusion is yet to be established. The higher rate of subsidence and occurrence of osteolysis seen in association with PLDLLA cages in this study remain worrisome.

Magnetically isolated, peripheral blood-derived CD133+ cells were used as the therapeutic agent of spinal cord injury (SCI). A rat model was used to investigate the hypothesis that the cell therapy using this clinically accessible cell fraction could be an attractive option for injured spinal cord. ⋯ The administration of CD133+ cells has a therapeutic potential to a rat spinal cord injury model and could be an optional treatment for spinal cord injury in the clinical settings.

Randomized Controlled Trial Multicenter Study
Effectiveness of a lumbar belt in subacute low back pain: an open, multicentric, and randomized clinical study.
Multicentric, randomized, and controlled study of clinical evaluation of medical device in subacute low back pain. ⋯ Lumbar belt wearing is consequent in subacute low back pain to improve significantly the functional status, the pain level, and the pharmacologic consumption. This study may be useful to underline the interest of lumbar support as a complementary and nonpharmacologic treatment beside the classic medication use in low back pain treatment.

Randomized Controlled Trial
Steroids and risk factors for airway compromise in multilevel cervical corpectomy patients: a prospective, randomized, double-blind study.
Prospective, randomized, double-blind study. ⋯ Based on our data, we cannot recommend intravenous dexamethasone for prevention of delayed extubation after multilevel anterior cervical corpectomy and strut grafting procedures.

Randomized Controlled Trial
RhBMP-2 versus iliac crest bone graft for lumbar spine fusion in patients over 60 years of age: a cost-utility study.
Randomized clinical trial. ⋯ There are more complications, increased need for additional treatment and revision surgery in patients over 60 years old receiving ICBG compared with rhBMP-2/ACS. This may account for higher costs and lower improvements in utility seen in patients receiving ICBG compared with rhBMP-2/ACS in this study population.
