we are transparent in our efforts to heal the injured poor




Dr. Lewis Zirkle

Diversity creates equality of fracture care.

The SIGN Network is like a machine moving steadily toward creating equality of fracture care throughout the world. Each part symbolizes SIGN Staff, Surgeons, Volunteers and Donors, who all rely on each other as SIGN Implants are used to treat increasing numbers of patients in developing countries.

I see the results of SIGN Surgery on the database every day when I am in the U.S. The comments on the database by surgeons in developing countries often express new ideas and new indications for SIGN Implants. The x-rays demonstrate the process of fracture healing and the pictures of the patients squatting and smiling have been shown to demonstrate fracture healing better than the x-rays. We realize the smile is not quantitative but smiles are contagious as an expression of joy and appreciation.

These are patients who would have severe disability due to their fractures if their surgeons were not excellent surgeons and did not have access to SIGN Implants. These surgeons understand fracture principles and enthusiastically treat their fellow countryman without using sophisticated equipment.

Our generous donors are essential to the network as the number of SIGN Programs and different implants increases. We are like a big family.

Financial Accountability

SIGN is a registered non-profit corporation in the state of Washington in the United States of America.

The majority of our funding comes from individual contributions given to us by people like you.

The economic conditions in most of the countries we work in require that we donate the SIGN Implants to the hospitals. However, about 1/3 of our funds come from cost reimbursement programs that we have in a few of the government hospitals, with other non-profit organizations and with implant distributors in Vietnam, Indonesia, Ethiopia, and Guatemala. We do not profit from these sales. Rather, the cost reimbursement program enables us to start new programs in other areas of great need.

89% percent of our budget went directly to supply the SIGN Surgeons with the implants and training needed to care for their patients.

Officers and Board

The SIGN Board of Directors is a volunteer governing board, providing high-level oversight for the organization. Most of the Board Members are orthopaedic surgeons, or come from orthopaedic for-profit companies. They each play a unique role in SIGN’s Mission.
