Insights
Ultrasound offers a valuable, non-invasive method for evaluating infant clubfoot deformity and its correction. This technique correlates well with the clinical Pirani score, improving diagnostic accuracy.
Area of Science:
- Pediatric Orthopedics
- Medical Imaging
- Biomechanical Analysis
Background:
- Conventional imaging has limitations in evaluating infant clubfoot.
- Ultrasound presents a promising, non-invasive technique for assessing clubfoot deformity.
- Monitoring correction of clubfoot using ultrasound is beneficial.
Purpose of the Study:
- To sonographically evaluate clubfoot deformity.
- To assess changes in sonographic parameters after Ponseti method treatment.
- To correlate ultrasonographic variables with the clinical Pirani score.
Main Methods:
- Prospective study of 82 feet in 54 children.
- Clinical assessment using the Pirani six-point system.
- Ultrasound measurements (7.5-12MHz transducer) of specific parameters.
Main Results:
- Key sonographic parameters (MMN, CCD, CCA, TAL, TCL) showed statistical significance.
- Sonographic parameters demonstrated a statistically significant correlation with the Pirani scoring system.
- Pearson correlation coefficient was used to establish the correlation.
Conclusions:
- Ultrasound is a simple, non-invasive, and accessible imaging modality.
- It enhances pathomorphological documentation of nonossified clubfoot and its correction.
- Ultrasound aids in monitoring treatment effectiveness for clubfoot.
Background:
Objective evaluation of infant with clubfoot is required as conventional imaging modality is of limited usefulness. Ultrasound shows to be a promising technique for assessing deformity and monitoring of clubfoot correction.
Aim:
Study was done to evaluate the deformity sonographically; to assess the changes in these parameters after treatment by Ponseti method and to correlate these ultrasonographic variables with clinical Pirani score.
Materials And Methods:
82 feet in 54 children were observed. Clinical assessment was done using Pirani six point system and ultrasound machine with 7.5-12MHz linear transducer was used to measure several parameters and data obtained was assessed to derive correlation between sonographic parameters and clinical system.
Results:
Medial malleolus navicular distance (MMN) measured on medial view, calcaneo-cuboid distance (CCD) and calcaneo-cuboid angle (CCA) measured on lateral view, talar length (TAL) measured on dorsal view and tibio-calcaneal distance (TCL) measured on posterior view showed statistical significance. Sonographic parameters correlated statistically with Pirani scoring system on measuring Pearson correlation coefficient.
Conclusion:
Ultrasound is a relatively simple, non invasive and widely available procedure that can improve pathomorphological documentation of nonossified clubfoot and its correction.
Level Of Evidence:
Level II prospective study, as per guidelines for authors.

The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
