PURPOSE: To assess cases of unilateral congenital talipes equinovarus (CTEV) and compare both Achilles tendons using [MSK USS].
METHODS: Twenty-two patients (44 feet) with unilateral CTEV presenting at the clubfoot clinic who met the inclusion criteria were recruited for the study. Biographic data was collected from the patients and both Achilles tendons scanned using high frequency ultrasound scan probe. The length, width, thickness were measured and area of the tendons estimated.
RESULTS: The median age of the patients was 32.5days with a male to female ratio of 1.2:1. The right foot was involved in 15 patients while the left was affected in 7 cases giving a ratio 2.1:1. The Achilles tendons in Clubfeet with mean length of 2.44(±0.3) cm were consistently longer than in the normal feet with mean length of 2.25(±0.3) cm. The width, thickness and area of the Achilles tendons in normal feet with mean values of 0.52(±0.01) cm, 0.22(±0.03) cm and 0.030(±0.01) cm2 respectively were consistently more than in clubfeet with mean values of 0.43(±0.1) cm, 0.20(±0.03) cm and 0.020(±0.01) cm2 respectively. The disparity in length between the normal and clubfeet when compared with the Pirani scores of the affected feet revealed no statistically significant difference. This was also noted when the disparity in width, thickness and area of Achilles tendons were similarly compared with Pirani scores.
CONCLUSION: The Achilles tendon of unilateral CTEV is longer but thinner and narrower than in the contralateral normal foot. The disparity in sizes of the tendon has no significant correlation with severity of the clubfeet.
