Summary

This study was a retrospective study. The investigators intended to review the preoperative paraspinal muscle imaging data of patients with lumbar spinal stenosis and degenerative scoliosis treated in hospital, and follow up the symptoms, quality of life and surgical complications at 1 year and at the last follow-up. The aims were: (1) to explore the correlation between paraspinal muscle imaging parameters and clinical outcomes; (2) based on the postoperative functional scores and the presence of complications, to explore the best combination of imaging parameters for predictive value of prognosis; (3) to evaluate the consistency between different measurement methods, and improve the standardized paraspinal muscle imaging assessment; (4) Combining the characteristics of individual bone mass and paravertebral muscle (functional and imaging assessment), to explore the correlation between bone loss and paravertebral muscle degeneration; (5) to explore a muscle-bone mass assessment system that could reflect the prognosis of patients.

Detailed description

This study was a retrospective study. The investigators intended to review the preoperative paraspinal muscle imaging data of patients with lumbar spinal stenosis and degenerative scoliosis treated in our hospital, and follow up the symptoms, quality of life and surgical complications at 1 year and at the last follow-up. The aims were: (1) to explore the correlation between paraspinal muscle imaging parameters and clinical outcomes; (2) based on the postoperative functional scores and the presence of complications, to explore the best combination of imaging parameters for predictive value of prognosis; (3) to evaluate the consistency between different measurement methods, and improve the standardized paraspinal muscle imaging assessment; (4) Combining the characteristics of individual bone mass and paravertebral muscle (functional and imaging assessment), to explore the correlation between bone loss and paravertebral muscle degeneration; (5) to explore a muscle-bone mass assessment system that could reflect the prognosis of patients. The investigators intended to review the patients who underwent posterior surgery for degenerative lumbar diseases from January 2010 to December 2019. 1. To review the patients who underwent posterior surgery in orthopedic department for degenerative scoliosis. The inclusion criteria were: (1) above the age of 45; (2) satisfy at least one of the following criteria: cobb angle \> 10°, sagittal vertical axis (SVA) \> 5cm, pelvic tilt (PT) \> 25°, or thoracic kyphosis (TK) \> 60°. The exclusion criteria were: (1) with a history of arthritic tumor or neuromuscular disease (2) with a history of spinal surgery. 2. To review the patients who underwent posterior surgery in orthopedic department for lumbar spinal stenosis. The inclusion criteria were: (1) above the age of 45; (2) diagnosis of lumbar spinal stenosis. The exclusion criteria were: (1) with a history of arthritic tumor or neuromuscular disease (2) with a history of spinal surgery.
