Prospective cohort study. ⋯ Contrary to previous reports, there was no evidence of consistent posterior osteophyte resorption during 5 years of follow-up.

Comparative Study
Can elderly patients recover adequately after laminoplasty?: a comparative study of 520 patients with cervical spondylotic myelopathy.
This was a prospective clinical comparative study of surgical outcomes for patients with cervical spondylotic myelopathy (CSM). ⋯ Pre- and postoperative JOA scores were low in elderly patients. However, the achieved JOA score was almost similar among the 3 groups. Thus, elderly patients could obtain reasonable recovery after cervical laminoplasty.
-
Retrospective review. ⋯ Risk factors for cervical SCI associated with OPLL were being elderly, having a mixed or segmental type of OPLL, and presence of OALL. Most instances of SCI occurred at edges of the OPLL or OALL. Severe spinal canal stenosis caused by OPLL was not an essential risk factor for developing SCI.

Randomized Controlled Trial
Oxiplex reduces leg pain, back pain, and associated symptoms after lumbar discectomy.
Prospective, randomized, blinded clinical trial. ⋯ These data demonstrate improvements in clinical outcomes resulting from the use of Oxiplex gel in discectomy procedures for treatment of lumbar disc herniation.
-
A cross-sectional study between subgroups of nonspecific chronic low back pain (NSCLBP) and asymptomatic controls. ⋯ Subgroups of NSCLBP had similar neutral spinal position deficits regarding error magnitude and variability, but subclassification revealed clear subgroup differences in the direction of the deficit. The trunk muscle activation was shown to be largely nondiscriminatory between subgroups, with the exception of superficial lumbar multifidus.
