Inclusion criteria

Inclusion criteria: All patients who undergo surgical treatment for spinal or spinal cord diseases at our institution between 2026 and 2030 as part of standard clinical practice. Eligible conditions include degenerative spinal diseases (such as myelopathy, intervertebral disc herniation, spinal canal stenosis, and ossification of spinal ligaments) as well as spinal deformities (including adult spinal deformity and idiopathic scoliosis). Surgical procedures include decompression surgery, fusion surgery, and deformity correction surgery, and eligibility is not restricted by the type of surgical procedure.

Exclusion criteria

Exclusion criteria: In principle, no exclusion criteria will be applied.

Design outcomes

Primary

Measure	Time frame
Changes in patient-reported outcome measures (PROMs) from preoperative baseline to 5 years postoperatively, with EQ-5D as the core outcome, and JOABPEQ, ODI, VAS, ZCQ, and postoperative satisfaction assessed as complementary measures.	—

Secondary

Measure	Time frame
The following variables will be evaluated as key secondary outcomes Patient related and disease related factors including disease etiology such as degenerative disease trauma infection tumor and spinal deformity Patient related factors including patient understanding of preoperative explanations Understanding will be assessed across three domains including understanding of the disease condition and planned surgical procedure understanding of the limitations of surgery and understanding of potential complications Understanding will be assessed across three domains including understanding of the disease condition and planned surgical procedure understanding of the limitations of surgery and understanding of potential complications Imaging evaluations using plain radiographs computed tomography and magnetic resonance imaging including spinal alignment pelvic parameters cervical parameters spondylolisthesis bone density related measurements soft tissue muscle evaluation calcification ossification and paravertebral muscle fatty degeneration based on the Goutallier classification Perioperative and surgery related factors including operative time blood loss dural injury location and repair method dural adhesion location and severity physical status classification blood pressure variability and administered medications Postoperative course and complications	—
