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