From TMH-NICE to ResTOR: An Eventful Journey A Treatise of developing a Tumor Megaprosthesis

The primary option for patients with osteosarcoma for many decades was an amputation to save life. A review in 1986 demonstrated that limb salvage surgery was as safe as an amputation and provided the evidence to change the surgical management of these patients to limb salvage surgery and megaprosthetic reconstruction. International developments since the 1990s formed the backdrop for the evolution of limb salvage surgery in India. Initial obstacles faced in India were that of patient affordability. In the late nineties, Dr. Ajay Puri and Dr. Manish Agarwal from the orthopaedic oncology department of Tata Memorial Hospital (Mumbai) in association with Sushrut-Adler initiated development of an indigenous limb salvage megaprosthesis (the TMH-NICE). This had to be a low-cost prosthesis by all means. This surgeon industry partnership over time led to overcoming many challenges and failures and continuous learning both on the clinical and engineering fronts resulting in the evolution of the ResTOR modular resection prosthesis system. This journey continues with improvements and modernization of the system contributing to cost-effective limb salvage surgery to patients in India and a number of other countries.
