A Moment in History

Jean-Louis Petit

Jean Louis Petit
(1674 – 1750)

French surgeon and anatomist, Jean Louis Petit was born in Paris in on March 13, 1674.  His family rented an apartment at his house to Alexis Littre (1658 – 1726), a French anatomist. Petit became an apprentice of Littre at seven years of age, helping him in the dissections for his lectures and at an early age became the assistant in charge of the anatomic amphitheater.

Because of Petit’s dedication to anatomy and medicine, in 1690 at the age of sixteen, became a disciple of a famous Paris surgeon, Castel.

In 1692, Petit entered the French army and performed surgery in two military campaigns. By 1693 he started delivering lectures and was accepted as a great surgeon, being invited to the most difficult operations.  In 1700 he was appointed Chief Surgeon of the Military School in Paris and in the same year he received the degree of Master of Surgery from the Faculty of Paris.

In 1715 he was made a member of the Royal Academy of Sciences and an honorary member of the Royal Society of London. He was appointed by the King as the first Director General of the Royal Academy of Surgery when it was founded in 1731.

Petit’s written works are of historical importance.  “Traite des Maladies des Os” ( A Treatise on Bone Diseases);  “Traite des Maladies Chirurgicales et des Operation” (A Treatise on Surgical Diseases and their Operations” This last book was published posthumously in 1774. He also published a monograph on hemorrhage, another on lachrymal fistula, and others.

He was one of the first to perform choIecystotomy and mastoidotomy. His original tourniquet design for amputations saved many in the battlefield and the design of the same surgical instrument today has not changed much since its invention by him.

His name is remembered in the lumbar triangle, also called the "triangle of Petit", and the abdominal hernia that can ensue through that area of weakness, the lumbar hernia or "Petit's hernia".

2017 AACA Meeting (3)

2017 AACA Meeting – Tuesday, July 18.

This is the 2017 Meeting of the American Association of Clinical Anatomists in Minneapolis, MN. This 34th meeting of the association, gets together over 300 clinical anatomists, anatomists, physicians, and students from all over the world.

The meeting started with the official welcome by the president of the AACA, Neil S. Norton, Ph. D., and the welcome by our local Minnesota host Tucker W. LeBien, Ph.D.

Unfortunately, our Honored Member James D. Collins, M.D., is sick and could not attend. We all wish him well.

The rest of the day was spent in poster sessions, the Tech Fair, and a reception where new AACA members can meet our mentors and possibly connect throughout their careers. The AACA aims to help its members through these activities.

We also had time to visit the exhibit hall where our sponsors can present their products. We sincerely thank them for their contribution.

One of the presentations that caught my attention was the use of augmented reality in anatomy, where you can see an anatomical structure floating in the air superimposed on the environment. 3D anatomical resources were also presented by the exhibitors.

One of the highlights of my day was to meet again with Victor M. Spitzer, Ph.D., (Honored Member AACA 2014) and talk about meeting in Colorado at his lab, and the incredible revolution in anatomy that he started with The Visual Human Project. I invited him to become a contributor to our blog…. Hope he accepts!

The day ended with some of the attendees to the meeting going to see a New York Yankees vs, the Minnesota Twins baseball game…. I stayed. Unfortunately for our hosts the NYY won 6-3.

More nice stuff tomorrow!!!
