Observational Study
Does Duration of Pain at Baseline Influence Longer-Term Clinical Outcomes of Low Back Pain Patients Managed on an Evidence-Based Pathway?
Nonrandomized longitudinal observational study. ⋯ Baseline pain duration would appear to be of clinical importance. Patients with shorter baseline pain duration demonstrated better outcomes. Those with ≥12 month's duration of pain may need additional support during their management to achieve clinically relevant functional improvements in the medium-to-long term. These findings raise questions about the decision by NICE to move away from duration of pain to differentiate management of LBP patients.Level of Evidence: 3.

Single-center retrospective case series. ⋯ 3D virtual planning and 3D-printed patient-specific drill guides appear to be safe and accurate for pedicle and lateral mass screw insertion in the cervical and upper-thoracic spine. The quantitative 3D deviation analyses confirmed that screw positions were accurate with respect to the 3D-surgical plan.Level of Evidence: 4.

Retrospective case series. ⋯ The CT-confirmed fusion rate of OCF was 77.2% over an average 89.7-month follow-up. Compensatory sagittal alignment change can occur in the unfused subaxial segments in conjunction with the alignment change in the instrumented OC segments, whereas the horizontal gaze was maintained. Strong consideration for the intraoperative measurement of the OC2A should be given during OCF to minimize both early and long-term complications.Level of Evidence: 4.

Retrospective chart review. ⋯ SCSs can be effective options for treating lumbar back pain and radiculopathy. Our study suggests that the presence of mild structural deformities does not adversely affect outcomes of permanent SCS placement and as such should not preclude this population from benefiting from such therapies.Level of Evidence: 4.

Technical case report. ⋯ This novel surgical technique is considered to be able to be a safe and effective alternative to the conventional treatment of selective cases of thoracic myelopathy caused by concurrent OPLL and OLF at the same thoracic level.Level of Evidence: 4.
