[Corrective surgery for lower limb length discrepancy and malalignment in paediatric orthopaedics]

Area of Science:

• Pediatric Orthopaedics
• Biomechanical Analysis
• Skeletal Development

Background:

• Lower limb length discrepancy and malalignment are common structural pathologies in pediatric orthopaedics.
• These conditions can significantly alter lower limb biomechanics and joint loading.
• Asymmetrical mechanical stress distribution may predispose affected joints to early-onset arthritis.

Purpose of the Study:

• To review and define the tolerance limits for various lower limb malformations in children.
• To describe and evaluate innovative surgical and non-surgical techniques for correcting these pediatric orthopedic anomalies.
• To provide a comprehensive overview for clinicians managing limb length discrepancies and malalignments.

Main Methods:

• Systematic literature review of pediatric orthopaedic studies.
• Analysis of biomechanical principles related to limb alignment and joint function.
• Review of current and emerging treatment modalities for lower limb malformations.

Main Results:

• Established ranges for acceptable limb length discrepancies and angular malalignments.
• Detailed description of surgical techniques including epiphysiodesis, osteotomies, and lengthening procedures.
• Evaluation of non-operative management strategies and their efficacy.
• Discussion of the correlation between malalignment severity and risk of arthritic changes.

Conclusions:

• Accurate assessment of limb malalignment and discrepancy is crucial for predicting joint health.
• A variety of innovative techniques offer effective correction options for pediatric patients.
• Management strategies should aim to restore biomechanical balance and prevent secondary arthritic degeneration.
