Lesgaft-Grinfelt Triangle

The Lesgaft-Grinfelt triangle (also known as the “Lesgaft-Grinfelt triangle”) is a unique anatomical landmark that was discovered in the 19th century and named after two prominent scientists - Peter Frantsevich Lesgaft (1837–1909) and Jacques-Cyril Grimfelt (1840). -1913).

Lesgaft was a Russian anatomist and physiologist who conducted research in the field of physical culture and sports. He developed a number of training techniques to strengthen muscles and improve physical fitness. Grimfelt was a French surgeon who specialized in the treatment of injuries and diseases of the musculoskeletal system.

However, despite the fact that Lesgaft and Grimfelt worked in different fields of medicine, their scientific achievements overlapped in the study of human anatomy. They both discovered that the human neck contains a unique area that connects muscles, tendons and blood vessels. This area was called the “Lesgaft-Greenfelt triangle”.

The Lesgaft-Grinfelt triangle is an important guideline when performing operations on the neck and spine, as well as in the treatment of injuries and diseases of the musculoskeletal system. It helps surgeons locate important anatomical structures and avoid damage.

The discovery of the Lesgaft-Greenfelt triangle became one of the most significant scientific achievements in the field of anatomy and medicine. It has improved the quality of treatment and increased the efficiency of operations in this area.



The Lesgaf-Ginfeld triangle is a concept in medical science that was first introduced by Paul Friedrich Lesgaft and John Sinclair Gienfeld in 1899. This term describes the combination between the musculoskeletal, nerve structures and blood vessels that connect to the hips, legs, knees and lumbar spine. These structures interact to provide movement of the body.

Lesgaf developed the theory of biomechanics of movement, and Ginfeld was a surgeon. They believed that normal movement is only possible with the simultaneous use of all three mentioned structures
