The Relationship of TRIZ Principles to Deformity Correction in Surgery

Robert Joseph, DPM, PhD

Charcot neuroarthropathy is a devastating and crippling condition that results in foot and ankle deformities which cause wounds. At one time, amputation was the primary treatment of severe Charcot deformities however advances in surgical instrumentation and surgeon technique now enable reconstruction of deformities that previously required amputation. The pathway of innovation in Charcot surgery is consistent with applications of TRIZ principles however formal adoption of systematic processes of innovation in surgery is uncommon.

Several challenges exist to surgeon adoption of systematic methods of innovation and include 1) difficulty applying engineering based systems to clinically relevant physiology   2)   contextual differences between systematic processes of innovation and impromptu innovation that most commonly occurs in surgery when complications arise. This presentation will include a surgical case series demonstrating how select TRIZ principles apply to advancements in Charcot surgery. Recommendations will be made on how TRIZ concepts can be contextually framed to facilitate physician oriented problem solving in a patient care environment. Conceptual relationships between several TRIZ principles and clinical physiology will be highlighted through case studies.

A tool to estimate the strength and life of a Patent

TRIZ (Theory of Inventive Problem Solving) classifies inventions into five novelty levels. At level 1 are slight modifications of the existing systems.  At level 2 are those inventions that resolve a system conflict or contradiction using usually inventive solution or inventive principle used to solve similar problems in other systems.    At level 3, the inventions change one subsystem or resolve the system conflicts in a fundamental way. At level 4, the invention gives birth to new systems using interdisciplinary approaches. The level 5 inventions are closer to a recently discovered scientific phenomenon. See article for a complete discussion.

Alexander Selyutsky - a key figure in the history of TRIZ!

Alexander Selyutsky

Selyutsky Alexander Borisovich was born April 6, 1933 to an intelligent Jewish family residing in Leningrad. During the World War II the plant where his father was working was evacuated to the Urals, and the family (the parents and Alexander) moved to Chelyabinsk. Here, Alexander graduated from high school. He wanted to go to a military school, but didn’t pass vision test and entered the Chelyabinsk Polytechnic Institute. In his first year he was forced to learn boxing (because of frequent anti-Semitic attacks) and became a Komsomol activist.

After graduation, he was sent to Petrozavodsk Onega tractor plant, where he worked as a designer. He continued leading a very active social life, organized and led voluntary militia patrolling the streets of the city because the situation was very criminal. In the search for more satisfying work he became interested in patenting, completed appropriate courses and became a patent agent.

In 1960, Alexander married Dolly Naumovna Audleys, and had a daughter Alla in 1961. The same year G.S Altshuller published a book " “Learn how to invent"[1] . After reading this book in 1965 Selyutsky wrote a letter to Altshuller. This letter started their acquaintance by correspondence. Since then, Alexander became one of the most dedicated Altshuller’s disciples and an active promoter of the emerging new science.

They finally met in 1968 in Dzintary (near Riga), at the seminar organized by the Central Board of VOIR (state leading inventors’ and innovators’ society) that invited Altshuller and several of his associates. It was the first time that Alexander and others got a chance to work under the direct guidance of Altshuller and to learn from him. Later, in 1983, Alexander participated as one of the instructors in the seminar conducted by G.S. Altshuller in Moscow at the Institute for continuous education for chemical and petroleum industries.
