Retrospective study (data analysis). ⋯ Surgery for DCM leads to significant functional improvement. However, better outcome was observed in younger individuals with lower CCI and absence of radiographic myelopathy signs. Therefore, DCM surgery, particularly before occurrence of high SI on MRI, seems to be essential for postoperative functional improvement regardless the above-mentioned confounders.Level of Evidence: 3.

Construct validity and reliability of the Japanese Version of the Lumbar Stiffness Disability Index.
Outcome study to determine the construct validity and reliability of the Japanese version of the Lumbar Stiffness Disability Index. ⋯ The construct validity and reliability of the Japanese version of the LSDI were confirmed. The J-LSDI can be used to evaluate lumbar stiffness and associated disability in Japanese patients following lumbar spinal surgery.Level of Evidence: 2.

A cross-sectional study with a test-retest design. ⋯ The Nepali versions of the NRS neck pain and NDI can be recommended for assessing pain and disability among patients with neck pain and cervical radiculopathy, but their responsiveness to change remains to be tested.Level of Evidence: 2.

Retrospective case-control study. ⋯ This is the first study to describe the sagittal alignment in patients with TOLF. The TOLF group showed a hypolordotic spine with a larger PI-LL mismatch compared to the age- and sex-matched control group with lumbar spondylosis.Level of Evidence: 4.
