Abstract

PURPOSE:

This study was undertaken to assess the feasibility of real-time elastosonography (RTE) of Achilles tendon in the clinical evaluation of a cohort of children affected by unilateral clubfoot, not surgically treated.

MATERIALS AND METHODS:

Twenty patients affected by unilateral clubfoot were evaluated. The study group consisted of 8 males and 12 females (mean age, 16 ± 7.3 months), all treated with the Ponseti method. Children were divided into two groups according to age: group 1 aged 0-18 months, and group 2 aged 18-60 months. Any further systemic pathological conditions were considered exclusion criteria. For each subject, RTE examination of the Achilles tendons was performed bilaterally, and then regions of interest (ROIs) were positioned.

RESULTS:

In children aged 0-18 months, the mean value ROI 1/mean value ROI 2 ratio was 2.0 ± 0.18 and it showed a statistically significant difference if compared to the same ratio from healthy tendons, 2.5 ± 0.17 (p < 0.05). In group 2 (children aged 18-60 months) the mean ROI 1/mean value ROI 2 ratio value was 1.8 ± 0.27, compared to a 2.04 ± 0.21 (p < 0.05) ratio in healthy tendons.

CONCLUSION:

RTE is a feasible, reliable and easily performed technique that allows an accurate study of the mechanical properties of Achilles tendon in children with clubfoot.
