Does malnutrition in clubfoot patients affect Ponseti technique and its outcome?

Abstract

Malnutrition is a crucial health problem predominantly in the developing countries. Malnutrition in children is one of the main risk factors for diseases and mortality. Club foot or congenital talipes equinovarus (CTEV) is the most common form of congenital orthopaedic abnormality. Over the past 20years, the Ponseti method is considered the gold standard for the treatment of clubfoot. Our objective is to determine the prevalence of malnutrition in clubfoot patients, and its effects on the outcome of Ponseti technique in patients presenting to the Orthopaedic Clinic of tertiary care Hospital in Karachi, Pakistan. The cross-sectional study was conducted from January to December 2018. Total 153 clubfoot patients were treated and the World Health Organization (WHO) classification of weight-for-age index was used to assess the nutritional status of patients, and its impact on outcome of Ponseti technique was recorded and analysed with a P value≤.05 as significant. Of the 153 patients, 112 (79.7%) were found in good nutritional status and 42 (20.6%) were malnourished. The average number of casts per patient and patients requiring 6+casts in the undernutrition group was higher compared with good nutrition group (45.5% vs 21.42%, respectively). The number of Achilles tenotomy performed in the undernutrition group was also higher (76.4% vs 51.8%). A significant correlation between patients' nutritional status and outcome of the Ponseti technique is found as it influences the number of casts, possible relapse and failure of treatment.
