Surgery plays a role of primary importance in the treatment of sarcomas of the soft tissues. The first objective of surgical treatment is the local control of the disease. Local recurrence is a serious event, that often requires amputation, and favors metastatic progression of the disease. Currently, except in very rare cases, conservative treatment is the treatment of choice, as it has by now been demonstrated that its results are equivalent to those obtained when demolitive surgery is used. In the distal sites of the limbs, superficial localization of the tendons, ligaments, and joints, the absence of anatomical compartments, make it difficult to perform wide conservative surgery. To this must be added that patients are often sent to see a specialist after a previous inadequate operation, and the presence of a contaminated surgical scar often requires exeresis of a wide area of the skin, sufficient to obstruct healing by primary intention. The use of revascularized free flaps allows for oncologically adequate conservative surgery to be performed, even in anatomical sites where amputation alone traditionally provided a safe surgical margin.
