With Irony About the Author

More than a quarter of a century ago, I asked myself the question: why do penguins and people waddle?

I studied the locomotion of people and animals, movement of machines, observed in zoos and museums, studied the structure of birds and human, experimented and analyzed, developed a mathematical apparatus. For the penguins the operation was developed: circular periacetabular osteotomy of the pelvis with rotational transposition of the proximal area of attachment of the ligament of the head of femur (ligamentum capitis femoris, ligamentum teres). A similar operation can improve the gait of some people too.

In the beginning, there was a question...

A Novel Technique for Proximal Fixation

Arkhipov SV. A Novel Technique for Proximal Fixation of Ligamentum Capitis Femoris Reconstruction: The Gifts of the Magi for Orthopedic Surgeons. About Round Ligament of Femur. January 14, 2026. DOI: 10.13140/RG.2.2.25269.33763 https://roundligament.blogspot.com/2026/01/the-gifts-of-magi-for-orthopedic.html Abstract Purpose: To describe an experimental technique for proximal fixation in ligamentum capitis femoris (ligamentum teres femoris; LCF) reconstruction using pubic and ischial portions anchored in corresponding pelvic bone tunnels, tested on synthetic hip joint models, and to propose it’s for arthroscopic application with visualization via an inferior portal and femoral tunnel. Methods: Synthetic polyurethane bone analogs (Synbone) of the pelvis and proximal femur were used to fabricate hip joint models. Acetabular cartilage analogs were created from self-curing plastic compound. Femoral tunnels were drilled along the neck axis from the subtrochanteric region below the tub...
