Surgery: Right Thumb Trapeziectomy / LRTI – April 18

Surgery: Right Thumb Trapeziectomy / LRTI

Starting at 10:00 AM CT, the Pan Am Clinic will open its operating room to students by streaming a live surgery. The patient’s surgery is a right thumb trapeziectomy /LRTI (ligament reconstruction tendon interposition). What’s that? Keep reading for a bit more information!

Watch it LIVE!

  • When: Tuesday, April 18th, 2017
  • Time: 10:00 AM CT
  • Length: TBD

Platform: Two Options:

  1. Polycom Video Conference Live Stream. If you have an endpoint, your students will be able to vocally interact with the surgeons and other students with an endpoint.
  1. Youtube: If you don’t have an endpoint don’t worry! You will still be able to watch the surgery live on youtube. Your students can submit questions to the live chat feed, and someone from Sisler will ask the questions for you!

Goals of Presentation:

The goal of this project is simply to make high tech procedures such as surgeries more accessible to students. A project like this allows students to understand what exactly goes on behind the scenes during a surgery, something that is nearly impossible to replicate in a typical classroom setting. This will be the fourth live surgery which has stemmed from partnership with Sisler High School, Pan Am Clinic, Manitoba Health, Telehealth, and Frontier School Division. Our first two surgeries were of ACL reconstructions, and last year we streamed a surgery fixing the “funny bone”.

About the Live Surgery

The surgery will be interactive, meaning the students will be able to ask surgeons questions (via Polycom, Youtube Live Chat, or Twitter) and receive feedback in real time. The surgery will be streamed to Sisler High School, and from there to students around the world thanks to a partnership with Frontier School Division. Check the description and link below for more info about this surgery.

“Most activities that involve grasping or pinching are possible because of the thumb’s remarkable range of motion. But dexterity comes at a price – an increased risk of osteoarthritis in the first carpometacarpal (CMC) joint, where the thumb meets the trapezium bone in the wrist. Sometimes the joint becomes so damaged that surgery is necessary.

Problems often start when the thick ligaments that hold the joint together loosen, allowing it to slip out of place. Over time, the articular cartilage that cushions the ends of the bones wears away, causing pain and limiting movement. Rheumatoid arthritis (RA) and other forms of inflammatory arthritis can also damage the first CMC joint – also known as the trapeziometacarpal joint (TMC).

In use for more than 40 years, LRTI is the most commonly performed surgery for thumb arthritis. The arthritic joint surfaces are removed and replaced with a cushion of tissue that keeps the bones separated. To accomplish this, surgeons remove all or part of the trapezium bone in the wrist.

A nearby tendon is detached at one end and then passed through a hole drilled in the thumb metacarpal. The remaining tendon is rolled like an anchovy and placed into the space where the bone was removed. Surgeons can also use artificial “anchovies” that eliminate the need to move a tendon.
