A prospective interventional trial, using a rat model of lumbar interbody fusion. ⋯ Our study suggests that using PRP with HA was beneficial for spine fusion. This combination may promote bone union and also decrease inflammatory neuropeptide in sensory neurons innervating the discs.

Comparative Study
Lumbar modic changes-a comparison between findings at low- and high-field magnetic resonance imaging.
A cross-sectional observational study. ⋯ There was a significant difference between low- and high-field MRI regarding the overall prevalence of any Modic change, but this had opposite directions for types 1 and 2: type 2 dominated in high field and conversely in high field [corrected]. The type of MRI unit should be taken into consideration when diagnosing patients with Modic changes
-
A retrospective cohort study. ⋯ Referral to a PTC/SC did not yield improved functional outcomes in this cohort. A major factor contributing to this finding was the length of time to referral to PTC/SC after the initial injury.
-
A prospective follow-up study. ⋯ An optimal intravertebral cement volume was identified for accomplishment of pain relief through PVP in painful OVCFs. Appropriate thresholds were provided to guide the operator.

Retrospective cross-sectional analysis of administrative data. ⋯ Both the supply of chiropractors and the utilization of chiropractic by older US adults varied widely by region. Increased chiropractic supply was associated with increased chiropractic use but not with increased chiropractic utilization intensity. Utilization of chiropractic care is likely sensitive to both supply and patient preference.
