Abstract

Limb salvage is a common procedure after extensive osteosarcoma resection. However, the long-term outcomes after limb salvage surgery (LSS) remain unclear. In this article, the case of a 24-year-old man who underwent hip disarticulation (HD) after an uncontrollable infection is presented. He was previously diagnosed with right distal femoral osteosarcoma and underwent LSS 10 years before disarticulation. Four years after LSS, an uncontrollable infection developed around the endoprosthesis, which eventually prompted HD. The Musculoskeletal Tumor Society (MSTS) functional rating system and the Toronto Extremity Salvage Score were used to compare the subject's activity statuses after LSS and HD. MSTS functional scores were 53.3% after LSS and 60% after HD. Toronto Extremity Salvage Scores were 78.3% after LSS and 95.8% after HD. The subject's emotional acceptance was 3 for LSS and 5 for HD (0 = worst and 5 = best). Both the MSTS and Toronto Extremity Salvage Scores were greater after HD than after LSS. The subject's improved emotional acceptance of the affected limb after HD contributed to the improved functional assessment scores. Alleviation of pain and other disabilities associated with the infection may have contributed to the higher functional scores after the more recent HD surgery. Even if amputation is unavoidable because of complications, high psychological acceptance may prevent a decrease in patient mobility and quality of life after amputation.
