Abstract:

Purpose: To compare morphologic data of the talus using magnetic resonance images with previously reported values of the humeral head and the glenoid as a potential graft source for both the humeral head as well as glenoid reconstruction in the setting of concomitant glenoid and humeral head defects.

Methods: All magnetic resonance images of the ankle were reviewed for assessment of the morphology and variation of the talus among individuals. Patients with post-traumatic, osteoarthritic, or surgical changes to the distal tibia about the mid- or hind- foot, or patients with incomplete medical records were excluded. Radiographic parameters that were measured included the maximum vertical height (MVH), the height to the talar neck, the radius of curvature (ROC) of the talar dome, ROC of the subtalar joint, and the maximum medial-to-lateral width of the talar dome. Demographic data also were collected on each individual. Statistical analysis was performed via a linear regression model with backwards elimination to determine which demographic data correlated most strongly with talar anthropometric values.

Results: A total of 82 study patients met inclusion criteria (59 male, 23 female; mean age 40.91 ± 14.69 years). Sex was found have a positive correlation of the following talar dimensions: MVH (P = .039), talar dome ROC (P < .001), and subtalar joint ROC (p = 0.001). Height was the most positive correlation for medial-to-lateral width (P < .001), height to the talar neck (P = .004), and also correlate for MVH (P = .004). Body mass index was found to have multicollinearity and was therefore not used as a variable.

Conclusions: Allograft talus appears to be a viable graft, as demonstrated in this anthropometric study for both reconstruction of the glenoid and humeral head when cases of bipolar glenohumeral bone loss are present.

Clinical relevance: This study aims to further evaluate potential allograft donor sites for bipolar lesions.

Wow the Steadman clinic and Doctor Matthew Provencher now that;s a super combination of expertise, experience, empathy, skill and a cherry picked staff with truly outstanding nurses and professional support staff. I was scared of shoulder surgery until I read Dr. Provencher BIO and talked to him. If your considering shoulder replacement surgery this is the place. In three weeks out now and people are amazed at my ability of movement and flexibility I have now. I love the Steadman Clinic and Dr. Matthew Provencher, He's Superman

Grateful to Dr Provencher and his team

I am a 75-year old, active, athletic woman. Over the last few years, both of my shoulders reached a point where severe arthritis was affecting even day to day tasks. It started with one shoulder in 2021 and recently the second reverse shoulder replacement – both with Dr Provencher. Before my first one, I had received various recommendations including adjusting my lifestyle. Dr Provencher looked at my MRI and x-ray and asked what I enjoy doing and was quick to let me know I could be back to my active lifestyle soon – and he was right. He reads images faster and more accurately than any doctor I have consulted. He has many options available and if you need surgery he is the one to do it. Surgery is quick and the recovery is much easier than I anticipated. I am 10 days out from my second reverse shoulder and have no pain and gaining mobility already! My case for both shoulders was a bit more complicated due to bone integrity, severe arthritis and bicep tears. Dr Provencher has dealt innovatively with both complications and makes it seem straightforward although I know it was not. He is not only one an extraordinary surgeon, but also, a caring human being who takes the time with his patients and makes himself available if questions arise. His team is second to none – Maddy, Madison, Sam, Scott, Jasmin and in pre-op, Layla and Kevin – in terms of commitment, competence, compassion and responsiveness. Both times I have felt cared for and that resolving my situation mattered to him. Wherever you live, Dr Provencher and his team are the ones to trust. There is no need to live a compromised life!

Success

If you are planning to see Dr Provencher ,do not hesitate ,do it. In 2018 Dr Provencher replaced my LCL. I had no complications and very little pain. I did my physical therapy as prescribed. I was able to ski 30 plus days the winter of 2019-2020. Before seeing dr Provencher I had spent a years time trying to solve my problem locally. I saw a pain specialist, orthopedic urgent care and a orthopedic surgeon. All had access to an mri done locally. It was also read by local radiologist. Pain dr gave injections as did orthopedic urgent care. No relief from pain. Orthopedic surgeon told me about arthritis, meniscus needing cleaning up and general deterioration from age. Told me to take ibuprofen for pain. At that time I reached out to Steadman Clinic. By luck of the draw I was assigned Dr Provencher. I took with me the mri that had been done locally and viewed by 3 local Drs and 1 PA. It took Dr Provencher less than a minute to tell me my problem was my LCL after viewing my mri. He told me my options . I selected surgery as I wanted to continue an active life style. It was a complete success!!
