Overview

[edit]

SIGN Fracture Care International (SIGN) is a 501(c)(3) non-profit organization equipping orthopaedic surgeons in low-and middle-income countries (LMIC). It was founded in 1999 by Dr. Lewis G. Zirkle, Jr. (born Lewis Greer Zirkle) to help surgeons treat patients with a fractured long bone.

SIGN provides doctors in LMIC with implants, instruments, and education. Dr. Zirkle invented and patented a system of orthopaedic instruments and implants designed for use in low-resource hospitals. The SIGN Model is to provide ongoing educational support for LMIC surgeons, then donate orthopaedic instruments and implants the surgeons need for their patients. Hospitals that partner with SIGN are called SIGN Programs (or, programs).

The SIGN System heals at a greater speed than healing by traction. [1] One independent study shows that SIGN’s implants provide angular and rotational stability despite fracture continuation, resulting in a high union rate and low complication rate.[2] Intermedullary nails are often regarded as the gold standard of care in femoral fractures.[3]

Founding

[edit]

In 1968, Dr. Zirkle was drafted into the United States Army to serve in the ongoing Vietnam War. While operating as a surgeon with the 93rd Evacuation Hospital, Dr. Zirkle treated wounded American and Vietnamese soldiers. Eventually, he made a formal request to begin operating on Vietnamese civilians, and after deliberation his request was granted.

After returning from Vietnam, Dr. Zirkle rotated through several hospitals while finishing his Army contract. It was during this time that Dr. Zirkle became involved with CARE MEDICO. In 1970, Dr. Zirkle traveled to Indonesia to provide training for local orthopaedic surgeons. Along with traveling, Dr. Zirkle would also send donations of medical equipment to the Indonesian hospitals. It wasn't until 1996 that Dr. Zirkle realized his efforts did not have the results he expected. On this trip, he encountered a patient who had been bed-ridden for three years due to a fractured femur. Dr. Zirkle proceeded to question the Indonesian surgeon overseeing the patient as to why surgery had not been performed. The surgeon informed Dr. Zirkle that the patient could not afford an implant, nor were the supplied implants suitable for use. All the donated implants required the use of instant imaging and power tools, neither of which were available in the hospital. This interaction led Dr. Zirkle to realize another solution was needed to treat patients who live in LMIC.

Dr. Zirkle recognized that providing training for surgeons was inadequate without also supplying usable implants and instruments. To accomplish this goal, Dr. Zirkle needed to partner with a US-based surgical implant manufacturing company. After many rejections, Dr. Zirkle connected with Portland-based Acumed, Inc. The founders of Acumed shared his desire to provide implants for people of LMIC. Acumed engineers created a prototype set of intramedullary (IM) nails and instruments that Dr. Zirkle took to Vietnam. The trip proved successful, as the Vietnamese surgeons demonstrated their skill with the nails after receiving instruction from Dr. Zirkle.[4]

After Dr. Zirkle returned from Vietnam, SIGN officially launched on January 29, 1999. By September, Dr. Zirkle had set up a small shop in Richland, Washington with a manual lathe and a mill for metal working. Dr. Zirkle and Acumed founder Randall Huebner handcrafted two IM nails in Richland, which Huebner took to Acumed headquarters for mass production. By the end of 1999, the SIGN technique was piloted in four hospitals (two in Vietnam, one in Indonesia, and one in Nepal).[4]

Surgeon Education

[edit]

SIGN partners with surgeons based in LMIC by providing orthopaedic education opportunities. SIGN hosts an annual conference for international surgeons and supports regional conferences and trainings around the world. In addition, mentor surgeons provide feedback on every surgery after reviewing x-rays and case notes submitted to the SIGN Surgical Database. SIGN also partners with medical schools in LMIC to support their orthopaedic residency programs, with the goal of increasing the number of qualified surgeons in their home countries.

Annual SIGN International Orthopaedic Conference

[edit]

The Annual SIGN International Orthopaedic Conference has been held in Richland nearly every year since 2001. During the COVID-19 Pandemic, the in-person conference was canceled with leadership opting to instead utilize online training tools. The SIGN Conference began as a way for Dr. Zirkle to showcase SIGN's mission to US-based orthopaedic surgeons. Many of these surgeons would then travel overseas to help establish SIGN Programs in LMIC hospitals. In 2004, LMIC surgeons attended the SIGN Conference for the first time, representing Kenya and India. Over the course of two days, the gathered surgeons shared their experiences of treating injured people in developing countries.

As time went on, LMIC surgeons began to take on more roles at the SIGN Conference. At the 2024 conference, over half of the overseas surgeons gave lectures to their colleagues. Lecture topics ranged from case studies to stories of experiences with patients.

Another educational aspect was added to the conference in 2017. That year, Surgical Training Institute (STI) donated their Mobile Bioskills Lab for the week-long conference. The Bioskills Lab gave surgeons a chance to practice their surgical skills on human cadavers. Surgical training was offered on four topics: foot and ankle, hip, elbow, and the pelvis. In 2018, a muscle flaps course was added. The success of the STI Mobile Lab prompted SIGN to build their own Bioskills Lab. Remodeling of SIGN Headquarters began in 2021, and was completed in time for the 2022 SIGN Conference.

At it's Pre-COVID height, the SIGN Conference hosted nearly 150 surgeons representing 28 different countries Recently, numbers have decreased to roughly 60 surgeons in attendance, representing 26 countries.

Traveling SIGN Sets and Mentors

[edit]

When SIGN first started, programs were established at new hospitals by surgical teams traveling from the United States. As the number of SIGN-trained surgeons have grown, local surgeons have taken over the roles of training and helping establish more programs.

Medical Device Manufacturing

[edit]

Intramedullary (IM) Nails

[edit]
Standard SIGN IM Nail

SIGN designs, manufactures, and donates intramedullary nails used to treat fractures in the femur, tibia, and humerus. The SIGN Nail is a solid, stainless-steel rod inserted into the canal of a fractured bone and stabilized with screws on each end. They are produced in a variety of lengths and thicknesses to allow surgeons to treat fractures for optimal results based on patient presentation.

SIGN Fin Nail

A design variant called the SIGN Fin Nail does not require interlocking screws at the distal end, using instead the friction of flanged fins to lock into the bone canal. This allows for quicker surgery.

SIGN Pediatric Fin Nail

SIGN’s Pediatric Fin Nail uses the fin design, but is scaled to fit in the bones of younger patients and avoids using screws in growth centers of the bone, allowing the patient to grow during healing and avoiding long-term complications.[5]

SIGN Instrument System

Orthopaedic Instruments

[edit]

SIGN manufactures a system of orthopaedic instruments used to insert the nail and stabilize it with interlocking screws. This system does not rely on live-view C-arm x-ray systems in the operating room. Instead, SIGN’s Target Arm and Slot Finder guide insertion of the nail and positions screws for stabilization.

The SIGN System can be used without electricity, making it possible to perform surgery in austere conditions, including after natural disasters or in conflict regions. This is notable, as the World Health Organization estimates nearly 1 billion people are served by healthcare facilities that lack reliable access to electricity. [6]

Manufacturing Compliance

[edit]

SIGN Fracture Care is registered with the United States Food and Drug Administration. SIGN manufactures finished medical devices in compliance with the United States Code of Federal Regulations, FDA Quality System Regulation (21CFR820) and maintains a quality management system that is certified to be compliant with ISO 13485:2016.

Patents Held

[edit]

SIGN Instruments and Implants patented with the United States Patent and Trademarks Office include:

Current Non-profit Operations

[edit]

Through contributions from individuals and foundations, SIGN donates education, instruments, and implants at no cost to hospitals or patients. In some cases, hospitals and distributors purchase implants at or below production cost.

As of November 2024, SIGN partners with more than 7,000 surgeons at 442 hospitals in 60 countries[1]. Surgeons trained by SIGN have cared for more than 447,000 patients with fractures since 1999, and provide surgery for around 30,000 patients per year.
