Does axial loading effect ulnar variance?

Описание: Wendy and Jan discuss a research article on The Effect of Axial Loading on Ulnar Variance.

0:00 Intro
1:39 Ulnar variance changes with weight bearing
2:10 Change in variance during axial load hasn't been investigated
2:35 The study
2:58 MRI and measurements
3:33 No change with age
4:11 Standardized test using analog scale
4:55 Importance of positioning
5:41 Study parameters
6:52 How load effects spreading
7:37 Significant findings
9:13 Table 1
9:40 Difficulties in working with mm differences
10:33 Outliers in Figure 2
10:45 Analyzing imaging
12:48 Spreading of distal radius and ulna visualized
14:51 Will surgical removal of part of ulna solve problem and bring back stability?
15:29 TFCC involvement
16:30 What would loaded test look like after procedure?
16:45 Was pain present?
19:30 More ulnar variance with more load, but cannot generate in imaging if it's painful
20:35 Is it the ulnar variance that causes the problem or is it a TFCC tear that causes the ulnar variance?
21:35 Axial load increases ulnar variance
23:00 Conclusion on study and future investigation

TFCC Talk is a discussion about all things triangular fibrocartilage complex and ulnar sided wrist pain. It is our hope to provide knowledge and education worldwide to those who are seek insight into their ulnar sided wrist pain.

Hello!! My name is Wendy and I am the inventor and patent holder of the WristWidget®, a solution for those with tears of the Triangular Fibrocartilage Complex.

I am an Occupational Therapist with a specialty in hands or CHT- Certified Hand Therapist. My fascination with the hands started at a young age when I became intrigued with the incredible dexterity that allowed me to play the piano, repair engines, write and function so well. It led me down the path of medicine at Chaminade University and then obtain a Bachelor of Science in Occupational Therapy in 1993. My work at Shriners Hospital in Hawaii led me to meet the hand therapist who demonstrated the incredible ability to mold and form materials for the hands of children. My passion excelled at Stanford University Hospital and Clinics where I received the most incredible exposure to all areas of medicine. I opened my private practice in Redwood City, California upon the birth of my second child. Then returned to my hometown to open 3 clinics in Honolulu, Kailua, and Queens. It was here that I invented the WristWidget®. Now the WristWidget® has expanded to all continents. I never imagined that I would have the opportunity to look at an injury every day, all day. With this has come great knowledge and understanding of an important dynamic of the human wrist.
My work now is entirely manufacturing, distribution and research. My hope is to influence the way we understand the TFCC and its incredible capacity to heal. With time and research, the work of the many who have shared their stories and experiences will be published. Hopefully soon, a patient with ulnar-sided wrist pain can receive an early and non-invasive diagnosis and an effective treatment.

Warmest Aloha to all of the mentors, teachers, patients, clinicians, friends, and family who have guided me along this path.
