Abstract

The "delta phalanx", first named by BlundeII Jones in 1964, is a triangular("delta-shaped") or trapezoidal phalanx with C-shaped epiphyseal plate causing progressive angular deformity of the digit with growth. Neither splinting nor physical therapy is effective in improving the condition. Surgical correction is indicated and several methods of correction have been reported. Authors have experienced a rare case of "delta phalanx" occuring in the proximal phalanx of the syndactylous digit.
