(a) Photograph of the dorsal oblique finger amputation. (b) Diagram showing the three branches of the DTPA. The ulnar branch was intact to the fingertip, and the other two were ruptured.

The amputated distal part of the finger included dorsal skin, the entire distal phalangeal bone, and the entire nail complex (Figure 1(a)). One artery in the stump appeared to be the distal part of the central branch of the DTPA (Figure 1(b)).
(a) Diagram showing the radial branch of the DTPA after cutting it. (b) The radial branch of the DTPA is anastomosed with the central pulp artery of the distal stump. (c) Photograph of the fingertip six months after replantation.

We incised the radial side of the DTPA and anastomosed it to the central pulp artery of the distal stump using 11-0 nylon suture (Figure 2(a, b)). His scores on these tests were 3.61 and 0.5, respectively. He was satisfied with the postoperative appearance and function of the reconstructed fingertip (Figure 2(c)).
