Leg length discrepancy in scoliotic patients.

Area of Science:

• Orthopedics
• Biomechanics
• Rehabilitation

Background:

• Scoliosis evaluation and treatment remain challenging, particularly regarding leg length discrepancy (LLD) and pelvic tilt.
• The efficacy of underfoot wedge corrections for LLD in scoliosis is debated due to assessment uncertainties and measurement limitations.

Purpose of the Study:

• To investigate the effectiveness of underfoot wedge corrections for leg length discrepancy in improving posture and reducing spinal deformities in scoliosis patients.
• To highlight the role of 3D opto-electronic measurements in assessing LLD, planning interventions, and monitoring treatment outcomes.

Main Methods:

• Utilized 3D kinematic optoelectronic measurements, force platforms, and baropodographic systems for comprehensive postural assessment.
• Analyzed data from 143 scoliosis patients (average age 16.4 years) with varying degrees of LLD and spinal curvature.
• Employed paired t-test to compare postural parameters before and after applying underfoot wedges for LLD correction.

Main Results:

• 94.4% of patients (135 out of 143) demonstrated improved posture after LLD correction.
• Significant postural improvements (p < 0.05) were observed in various parameters after wedge application.
• The study confirmed the efficacy of underfoot wedges in correcting leg asymmetry and re-balancing posture.

Conclusions:

• Underfoot wedge correction is an effective method for addressing leg length discrepancy in scoliosis, leading to significant postural improvements.
• 3D opto-electronic measurement systems are crucial for accurate assessment, tailored therapy planning, and effective monitoring of scoliosis treatment.
• This approach contributes to reducing spinal deformities and enhancing overall posture in scoliosis patients.
