    Abstract:
    BACKGROUND: Arterial deficiency in congenital clubfoot or congenital talipes equinovarus (CTEV) was postulated as either the primary cause of deformity or secondary manifestation of other bony and soft tissue abnormalities. The objectives of the study were to find any association between arterial deficiency with severity of CTEV and its treatment. METHOD: This prospective study conducted on 24 feet with CTEV (18 babies) with Pirani score ranging between 2 to 6. Eighteen normal babies (36 feet) were selected as control. We used Color Doppler Ultrasound to assess dorsalis pedis and posterior tibial arteries before initiating the treatment. Second ultrasound was performed in study group upon completion of Ponseti treatment. RESULTS: The patients were from one week to 15 weeks of life. Dorsalis pedis arterial flows were absent in 7 clubfeet (29.1%) while the remaining 17 clubfeet (70.8%) had normal flow. There was a significant association between Pirani severity score and vascular status in congenital clubfoot. There was a higher proportion of clubfeet having abnormal vascularity when the Pirani severity score was 5 and more. In study group, posterior tibial arteries were detectable and patent in all feet. All normal feet in control group had normal arterial flow. There was a significant difference in vascular flow before and after the Ponseti treatment (p 0.031). CONCLUSION: The study concludes that there is an association between Pirani severity score and arterial deficiency in CTEV. Ponseti treatment is safe in CTEV with arterial deficiency and able to reconstitute the arterial flow in majority of cases.
