Long-Term Follow-Up on the Donor Foot After Thumb Reconstruction Using Big Toe Wrap-Around Flap in Two Different...

The function of the donor foot has been affected after using big toe wrap-around flap for thumb reconstruction. A modified operation method has been developed to reduce the adverse effect on the donor foot. The current study compared the long-term effect of the classic and the modified operation methods on the donor foot. Gait analysis was carried out, including how the patient walked, the walking speed and walking distance, and how the patient jumped and ran. Plantar pressure was measured while the patient was standing and moving. A total of 45 patients who received the 2 different operation methods were included. The follow-up time was 4-10 years with a mean of 6.5 years. Various degrees of complications occurred for the 21 patients who received the classic operation method. For these patients, plantar pressure of the donor foot was obviously different comparing with the healthy unaffected foot while the patient was standing or walking. For the 24 patients who received the modified operation method, no obvious complications were observed and the plantar pressure of the donor foot and the healthy unaffected foot was similar while the patient was standing or walking. In conclusion, both the classic and the modified operation methods have affected the function of the donor foot after using the big toe wrap-around flap for thumb reconstruction. However, the donor foot was less affected when the modified operation method was used.
