Randomized Controlled Trial Multicenter Study Comparative Study
Initial fusion rates with recombinant human bone morphogenetic protein-2/compression resistant matrix and a hydroxyapatite and tricalcium phosphate/collagen carrier in posterolateral spinal fusion.
Prospective, randomized, unblinded study of iliac crest bone graft (ICBG) versus recombinant human bone morphogenetic protein-2/compression resistant matrix (rhBMP-2/CRM)in a posterolateral instrumented fusion procedure. ⋯ These early results are encouraging and suggest a more rapid incorporation and development of the fusion mass with rhBMP-2/CRM than iliac crest autograft in a single level posterior instrumented fusion.

Multicenter Study Comparative Study
The transition from acute to subacute and chronic low back pain: a study based on determinants of quality of life and prediction of chronic disability.
Follow-up study. ⋯ LBP influences disability and quality of life more than RP. Disability is predicted by pain duration and quality of life is predicted by disability, but pain severity predicts neither one of them. Changes related to determinants of disability and quality of life, and to the prediction of chronic disability, appear 14 days after the onset of pain, supporting that cutoff point for considering a patient as being subacute.

Review Case Reports
Successful reduction for a pediatric chronic atlantoaxial rotatory fixation (Grisel syndrome) with long-term halter traction: case report.
Clinical case report of atlantoaxial rotatory fixation (AARF) in a girl presenting with torticollis and neck pain. ⋯ From this case, we suggest that long-term traction could be another treatment method for chronic AARF, especially in children.

A case report of acute quadriplegia resulting from closed traction reduction of traumatic bilateral cervical facet dislocation in a 54-year-old male with concomitant ossification of the posterior longitudinal ligament (OPLL). ⋯ This case report highlights the advantages and shows some safety concerns regarding immediate, closed traction reduction of cervical facet dislocation with real-time neural monitoring in an awake, alert, oriented, and appropriately select patient before MRI studies in the setting of preexisting central stenosis from OPLL.

Randomized Controlled Trial Comparative Study
Efficacy of dilute betadine solution irrigation in the prevention of postoperative infection of spinal surgery.
Prospective, single-blinded, randomized study. ⋯ Our report is the first prospective, single-blinded, randomized study to evaluate the clinical effectiveness of dilute betadine solution irrigation for prevention of wound infection following spinal surgery. We recommended this simple and inexpensive measure following spinal surgery, particularly in patients with accidental wound contamination, risk factors for wound infection, or undergoing surgery in the absence of routine ultraviolet light, laminar flow, and isolation suits.
