Service to Bone Tumour Patients


Prior to 1988 in India, the treatment of malignant bone tumours was by amputation of the limb to save the life of the patient. Dr Mayilvahanan has revolutionized the treatment of bone tumour patients by introducing the technology of Limb Salvage Surgery by Custom Mega Prosthesis in Tamil Nadu. By this specialized technique he has avoided amputation in patients with bone cancer and pioneered Limb Salvage Surgery.


His impressive and unmatched series of 2250 cases of Custom Mega Prosthesis in 34 years (1988 to 2021) has earned him National and International acclaim. Among the 1000 Orthopaedic surgeons in Tamilnadu and 10,000 Orthopaedic surgeons in India, Dr. Mayilvahanan has consistently been doing this work for over three decades. This is the largest personal series by the single surgeon in the whole world.


Service to Society


The cost of the imported custom mega prosthesis was 4,00,000/- Working on the philosophy of Indigenous Technology Development based on locally available resources in biomedical materials, he has reoriented and improved the health care facilities to bring it within the reach of the common man. The scientifically designed and indigenously manufactured Custom Mega Prosthesis has brought down the cost to an affordable INR 1,00,000/- Thus, he has made the Custom Mega Prosthesis a cost effective treatment, which is affordable by all sections of the society.


The Indigenisation of the manufacturing process has cut down the cost of this procedure to one tenth and enabled service oriented organization like the Cancer Institute, Adyar and the Govt. General Hospital, Chennai to offer this invaluable option to their patients. For the needy patients attending the premier tertiary care Public Hospitals in Tamilnadu, the prosthesis has been provided free of cost, bringing this technology within the reach of the poorest members of our society.
