Abstract

Reconstruction for fingertip defects categorized as Type 3 and Type 4 in Allen's classification is challenging, because surgeons need to reconstruct not only the pulp but also great parts of the distal phalangeal bone. This paper introduces an original technique for the reconstruction of defects of these types. The defects of seven fingers (two small fingers and five index fingers) of seven patients (three males and four females; aged 14-44 years) were repaired. After the fingertip is divided in a fish-mouth fashion to expose the stump of the distal phalangeal bone, a curved block of hydroxyapatite is grafted to fill the phalangeal defect and straighten the nail bed. A rectangular flap is raised from the dorsal side of the neighbouring finger in the region between the PIP and DIP joints. Then the fish-mouth region carrying the grafted hydroxyapatite is covered with the rectangular flap to reconstruct the pulp. The rectangular cross-finger flap is separated 3-4 weeks postoperatively. In all seven cases, the flap survived completely. Infection developed in no case. In all cases, aesthetic appearance of the pulp and nail presented improvement, satisfying the patients. Combined usage of hydroxyapatite and a cross-finger flap from the neighbouring finger is an effective method for the reconstruction of type 3 and type 4 defects in Allen's classification.
