| Ideal uses |
Fingertip cover.
Less PIP flexion needed for more ulnar fingers. |

Beefy hands
may not allow small fingertip to reach the thenar area. PIP flexion contractures
are more likely if not hyperextensible preop or if flap is divided after
2 weeks. |
| Tips, misc and pics |
Inject PIP
joint with 1 mg Kenalog at the time of flap placement to lessen chance
of postop contracture. |
