Physiolysis for correction of the delta phalanx in clinodactyly of the bilateral little fingers.

We report the results of long-term follow-up after Vickers' physiolysis of the trapezoidal delta phalanx in a boy aged five year and six months with bilateral clinodactyly of the little finger. Radial deviation of the little finger was corrected from 36 degrees to 15 degrees on the left, and from 35 degrees to 15 degrees on the right at last follow-up six years and five months after surgery. The patient's parents were satisfied with the cosmetic appearance. X-ray film showed the abnormal distal epiphyses of the middle phalanges of the little fingers had disappeared.
