Wachstumsprothesen nach Sarkomresektionen im Kindes- und Jugendalter

Abstract

Bei der Behandlung eines Sarkoms im Kindesalter sind Wachstumsprothesen eine wichtige Alternative zu Amputation und Umkehrplastik. Mittlerweile gibt es mehrere Systeme, die entweder invasiv oder nichtinvasiv verlängerbar sind. Das Ziel dieses Beitrages ist es, neben der Indikationsstellung und den Erfolgsaussichten die altersspezifischen Probleme aufzuzeigen und Lösungsmöglichkeiten darzustellen.

Construction and Validation of Nomograms for Predicting the Prognosis of Juvenile Osteosarcoma: A Real-World Analysis in the SEER Database

“…The extent of tumor resection is based on the Enneking standard, which not only removes the tumor itself, but also removes healthy tissue 5 to 7 cm away from both ends of the tumor. 7 The reconstruction methods include tumor segment resection plus joint fusion, autologous or allograft bone transplantation, tumor segment bone inactivation and replantation, artificial joint prosthesis replacement. 8 With the popularization of neoadjuvant chemotherapy and the development and improvement of surgical techniques, the 5-year overall survival rate of osteosarcoma patients has gradually increased from 60% to 80%.…”

Surgical Treatment of Bone Sarcoma

“…Limb length equality was obtained in 79% patients with the Phenix-Repiphysis system and in 84% with the Stanmore implant. Additionally, Windhager et al [ 50 ] state, in their review, satisfactory functional results with an averaged Musculoskeletal Tumor Society score of 78.3 but a high complication rate of 27.3% of infections and 22.4% of mechanical failure. It is this high complication rate that prompts some authors to still argue in favor of rotationplasty [ 51 ].…”
