Congenital constriction band syndrome.
A retrospective study of 55 patients with congenital constriction band syndrome was performed. Multiple extremity involvement was found to be the most common clinical feature associated with the disease, and 34% of the patients studied were premature at birth. Malformations included constriction bands, clubfoot, intrauterine amputation, syndactyly, and acrosyndactyly (fenestrated syndactyly). The extremities were most often affected distally, involving the longer central fingers and medial two toes. More proximal involvement with constriction bands was associated with a higher frequency of neurologic deficit. Significant leg-length discrepancy exceeding 2.5 cm was seen in 9 of 38 patients (24%) with lower extremity involvement, a condition that has not been previously reported.
