Paraspinal Muscle Degeneration, Bone Mass and Clinical Outcomes in Patients With Lumbar Degenerative Diseases

December 28, 2021 updated by: Peking University Third Hospital

The Relationship Between Paraspinal Muscle Degeneration and Bone Mass and Clinical Outcomes After Surgery in Patients With Lumbar Degenerative Diseases

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.

Study Overview

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Disability
Time Frame: 12 months; through study completion, an average of 3 years
The Oswestry Disability Index (ODI) (0-100, high score indicates severer disability) is used to assess disability.
12 months; through study completion, an average of 3 years
Low Back pain
Time Frame: 12 months; through study completion, an average of 3 years
The Visual Analog Scale (VAS) (0-10, high score indicates more pain) is used to evaluate leg pain.
12 months; through study completion, an average of 3 years
Leg pain
Time Frame: 12 months; through study completion, an average of 3 years
The Visual Analog Scale (VAS) (0-10, high score indicates more pain) is used to evaluate leg pain.
12 months; through study completion, an average of 3 years
Sagittal balance
Time Frame: 12 months; through study completion, an average of 3 years
Sagittal balance is evaluated by anteroposterior and lateral X-ray of the whole spine at the standing position.
12 months; through study completion, an average of 3 years
Bone nonunion
Time Frame: 12 months; through study completion, an average of 3 years
Bone nonunion was evaluated by dynamic X-ray. Bone nonunion was defined as 1) there was no continued bone fusion mass at any fusion segment; 2) any motion (greater than 3 mm or 3°) on flexion/ extension plain radiographs.
12 months; through study completion, an average of 3 years
Screw loosening
Time Frame: 12 months; through study completion, an average of 3 years
Screw loosening was evaluated on spine radiograph or CT. Screw loosening was defined when a 1mm or wider circumferential radiolucent line around the pedicle screw was confirmed.
12 months; through study completion, an average of 3 years
Proximal junctional kyphosis
Time Frame: 12 months; through study completion, an average of 3 years
Proximal junctional angle (PJA) was determined by the sagittal angle subtended by the inferior endplate of the uppermost instrumented vertebra (UIV) and the superior end plate of the vertebrae two levels above the UIV (UIV + 2). The definition of proximal junctional kyphosis (PJK) was PJA 10 or greater and at least 10 greater than the corresponding preoperative measurement.
12 months; through study completion, an average of 3 years
Proximal scoliosis progression
Time Frame: 12 months; through study completion, an average of 3 years
The proximal scoliosis progression (PSP) was defined as the disc wedging increased 10 degrees from postoperative to two-year follow up on the AP radiograph.
12 months; through study completion, an average of 3 years
