Clubfoot deformity in Down's syndrome.
The association of Down's syndrome (trisomy 21) with clubfeet has not previously been elaborated. Eight patients with a total of 15 clubfeet were identified for review. Five of these had trisomy 21 noted by chromosomal analysis, and 1 had a mosaic pattern. Two patients did not have chromosomal documentation, but had characteristic features of Down's syndrome. Interestingly, 2 patients had evidence of arthrogryposis as well as Down's syndrome. Four of the 8 patients had other orthopedic anomalies, including scoliosis, atlantoaxial instability, brachydactyly, and coxa valga. All 8 patients had an initial period of casting prior to any surgical intervention. Fourteen of the 15 feet required surgical intervention to afford correction of the deformity. The 6 feet with relatively long-term follow up (average: 5 years) showed that there was 1 excellent, 4 good, and 1 fair result using the criteria of Turco. It appears that, even though Down's syndrome is usually characterized by ligamentous laxity, when clubfeet are associated with this syndrome they are often resistant to nonoperative treatment, and surgical treatment seems to produce an acceptable result.
