Daniel Mollière (1848-1890): the French anatomist-surgeon who introduced Robin's pioneering osteoclast for the genu valgum observed in adolescents.

Inside the pages of the French medical treatises of the 19th century a forgotten osteoclast apparatus for the genu valgum observed in adolescents remained hidden waiting to be unearthed. It was Victor Robin's osteoclast, which has been used by the supreme French anatomist and surgeon Daniel Mollière. With the purpose to share a significant heritage on orthopaedics, a thorough research of the literature of the era was conducted. Our study resulted in the illumination of both Mollière's prolific figure and osteoclast's impact on orthopaedic surgery at that time. Having in mind Mollière's perseverance towards surgical apparatuses, his antiseptic measures inside his operating theatre, his published treatises, his surgical skills, we may effortlessly conclude that he stands among Lyon's best surgeons with an important contribution to orthopaedics.
