Microsurgical Reconstruction of Foot Defects: A Case Series with Long-Term Follow-Up.

(1) Background: Microsurgical reconstruction of foot defects with free flaps is rare as it is a challenging task for a surgeon. For extensive defects, advanced surgical procedures, such as free flap transfer with microsurgical anastomosis, may be the last chance to avoid major amputation. The aim of the study was to examine the opportunities and risks posed by free flap reconstruction of foot defects and to illustrate in which situations reconstruction is useful on the basis of case characteristics. (2) Methods: In this study, we retrospectively analyzed data of cases with free flap reconstruction of the foot from 2007 to 2022. Therefore, demographic data, comorbidities, information about the defect situation, data on the operational procedure, and complications were evaluated. (3) Results: A total of 27 cases with free flap coverage of foot defects could be included. In 24 of these cases (89%), defect coverage was successful. In 18 patients, some form of complication occurred in the postoperative stage. The most frequently used flap was the latissimus dorsi flap, with 13 procedures. (4) Conclusions: Foot reconstruction using free flaps is a proven procedure for the treatment of larger foot defects and can offer a predominantly good functional outcome. The lengthy process and possible complications should be thoroughly discussed in advance so as to provide criteria, suitably adjusted to the individual prerequisites of the patients, for deciding whether limb salvage using advanced surgical procedures should be attempted.
