Long-term follow-up of resection–replantation for sarcoma in the distal radius

Excerpt

For malignant bone and soft-tissue tumors of the forearm, various reconstructions after curative resection have been described [1, 2]. However, amputation is sometimes necessary for complete eradication when the tumors are large or have neurovascular involvement [3]. Resection–replantation is a surgical method for partial limb salvage for upper-extremity malignant tumors [4‐8]. Its principle is derived from rotationplasty, and the technique is similar. The tumor-bearing area is resected as a cylindrical segment that includes bone, soft tissues, involved skin, and sometimes vessels and nerves. The distal part of the arm is reimplanted with shortening, adjustment of all structures and, if necessary, vessel anastomosis [4‐8]. Resection–replantation is indicated for treating primary malignant tumors of Enneking stage IIB when any other limb-salvage procedures are not indicated and amputation appears to be the only way to achieve wide margins [5, 6]. Although this procedure can retain a relatively functional limb, there have been few reports that describe its long-term results [6, 7]. Here, the long-term result of resection–replantation for mesenchymal chondrosarcoma (MCS) in the distal radius of a 13-year-old boy is presented. …
