Limb length discrepancy in congenital talipes equinovarus

Area of Science:

• Orthopedics
• Pediatric Orthopedics
• Genetics

Background:

• Congenital talipes equinovarus (CTEV) is a common birth defect affecting the foot and ankle.
• Limb length discrepancy (LLD) can be a significant complication of CTEV, impacting patient outcomes.
• Understanding the prevalence and contributing factors of LLD in CTEV is crucial for effective management.

Purpose of the Study:

• To determine the prevalence of limb length discrepancy in patients with congenital talipes equinovarus.
• To assess the clinical significance and management of LLD in this patient population.
• To investigate the contribution of tibial and femoral shortening to LLD in CTEV.

Main Methods:

• Retrospective analysis of 536 patients diagnosed with congenital talipes equinovarus.
• Identification and measurement of limb length discrepancies greater than 0.5 cm.
• Analysis of surgical interventions and correlation with discrepancy magnitude and tibial/femoral shortening.

Main Results:

• A prevalence of 18% for LLD in unilateral CTEV and 4% in bilateral CTEV was observed.
• LLD necessitated surgical equalization in 5% of unilateral and 1% of bilateral cases.
• Tibial shortening was a major contributor to LLD, with 89% of unilateral cases showing at least 0.3 cm of tibial shortening.

Conclusions:

• Limb length discrepancy is a clinically significant issue in congenital talipes equinovarus, particularly in unilateral cases.
• Tibial shortening plays a substantial role in the development of LLD associated with CTEV.
• Early identification and management of LLD are important for optimizing functional outcomes in patients with CTEV.
