There is a low complication rate using Keystone flaps (this double VY is a clinical development from Diffenbach's original work of 1848(1)) and this technique is particularly useful in achieving wound healing especially after irradiation treatment. This surgical technique once mastered is easy to perform. Another bonus is that there is minimal use of postoperative analgesia. Additional XRT is well tolerated by the patients with minimal evidence of wound complications, while achieving an acceptable aesthetic appearance.

We studied the initiation and sequence of digital joint motion during unrestricted flexion and extension using a 3-D motion analysis of all fingers moving simultaneously. Our results showed that motion started in a single joint in 83%, of flexion and 80%, of extension cycles. The DIP joint initiated flexion and extension in the index, middle, and ring fingers, but in the little finger, flexion started in the PIP joint, and extension in the MP joint. The two most frequent sequences of joint movement during flexion of the three radial fingers were DIP-PIP-MP and PIP-DIP-MP. The two most frequent sequences during extension of the three radial fingers were DIP-MP-PIP followed by DIP-MP/PIP. In the little finger, however, the most frequent sequences during flexion were PIP-DIP-MP followed by DIP-PIP-MP and during extension, DIP-MP/PIP followed by PIP/DIP-MP.
