The treatment of a major osseous defect in orthopaedic oncology focuses heavily on surgical techniques that are intended to preserve the affected limb as much as possible. Hence amputation, rotationplasty and arthrodesis is avoided as much as each patient’s status will allow. The main options therefore involve the use of allograft and/or autologous graft and/or tumour prosthesis. And, in recent years modular segmental replacement systems have become increasingly popular as they offer the the surgeon a way to treat patients with defects which can vary significantly in size on an individual basis and with confidence.
Since it’s introduction in 1992 the MUTARS® (Modular Universal Tumour And Revision System) has been successfully used for the treatment of major osseous defects of the lower and upper extremities. Its modular design was developed in co-operation with Univ.-Prof. Dr. W. Winkelmann* (em. Director) and Univ.-Prof. Dr. G. Gosheger (Director), Department of General Orthopaedics and Orthopaedic Oncology at the University Hospital of Münster, Germany. The system shows good functional results and allows an individualised solution for major osseous defects, including arthroplasties of the adjacent joints.
