      Abstract

      Background

      Medial femoral condyle(MFC) flap is frequently used in hand reconstruction, but like other buried flaps, MFC is not easy to monitor and follow.In this study, we present our adipofascial and periosteal tissue technical modifications and results for MFC free flap monitoring and compare different monitoring methods.

      Methods

      Twenty one patients with wrist bone or metacarpal defect reconstructed with MFC flap were included in the study. Adipofascial tissue in wrist defect and periosteal tissue in metacarpal defect were selected as MFC flap's monitor. Patient characteristics, type of injury, flap size, early or late-period complications, flap elevation time,satisfaction scale, visual analogue scale (VAS) and postoperative X-ray view were noted.

      Results

      There were 3 female and 18 male patients in the study. The mean age of the patients was 50.8 (38–68). The elevation times of flaps with adipofascial and periosteal monitors were 48 and 53.3 min, respectively. The satisfaction scale averages for the adipofascial and periosteal monitor groups were 3.5 and 3.54, respectively. The VAS scores of the adipofascial and periosteal monitor groups were 2.9 and 3.9, respectively. The flap sizes with periosteal and adipofascial monitors were 10.48 cm3 and 1.36 cm3, respectively. There was no statistically significant difference between flap elevation, VAS, and satisfaction scale (>0.05). There was a statistically significant difference in flap sizes. (<0.05)

      Conclusion

      MFC free flap is frequently used in wrist and metacarpal reconstruction. Monitor selection according to the defect area positively affects the prognosis of the flap in the postoperative period.
