Spinopelvic Parameters as Risk Factors of Nonspecific Low Back Pain: A Case-Control Study

Area of Science:

• Orthopedics
• Radiology
• Biomechanical Engineering

Background:

• The relationship between spinopelvic alignment and low back pain (LBP) is complex and not fully understood.
• Specific spinopelvic parameter patterns potentially contributing to nonspecific LBP remain unclear.
• This study investigates spinopelvic parameters as risk factors for nonspecific LBP.

Purpose of the Study:

• To evaluate the role of spinopelvic parameters in the incidence of nonspecific LBP.
• To identify specific spinopelvic parameters associated with increased LBP risk.
• To compare spinopelvic parameters between LBP patients and healthy controls.

Main Methods:

• A case-control study involving 148 patients with nonspecific LBP and 148 healthy controls.
• Radiographic assessment of spinopelvic parameters: lumbar lordosis (LL), sacral slope (SS), pelvic tilt (PT), and pelvic incidence (PI).
• Univariate and multivariate logistic regression analyses were performed, controlling for demographic factors like age, gender, BMI, smoking, and occupation.

Main Results:

• Female gender, higher BMI, smoking, and blue-collar jobs were associated with higher LBP risk in univariate analysis.
• Lumbar lordosis (LL), sacral slope (SS), and pelvic incidence (PI) were significantly greater in LBP patients (univariate analysis).
• Multivariate analysis identified female gender (ORAdj = 4.26) and LL (ORAdj = 1.58) as significant predictors of nonspecific LBP.

Conclusions:

• Spinopelvic parameters, particularly lumbar lordosis (LL), are potential risk factors for nonspecific LBP.
• A greater LL may indicate an increased risk of developing LBP.
• While LL is a key factor, the contribution of other spinopelvic parameters to LBP should also be considered.
