Rational treatment for multiple digit congenital absence: case report of nonvascularized toe phalangeal transfers and distraction lengthening for symbrachydactyly.

Abstract

A case is discussed in which a young male was born with symbrachydactyly of multiple digits in whom nonvascularized proximal toe phalanges were transferred to the aphalangic digits when he was an infant. This initial surgical procedure was later followed by webspace deepening and ultimately by distraction lengthening of the digits. At 8 years of age, he has a very functional hand with mobile metacarpophalangeal joints in all reconstructed fingers. In fact, he uses this reconstructed right hand as his dominant extremity. The case is discussed in context of phalangeal growth potential, specific indications for this type of reconstruction, and final long-term outcome. This case also helps to recommend rational treatment protocols for similar congenital hand anomalies.
