Abstract:

Purpose: To evaluate whether characteristics such as age, height, weight, sex, or body mass index affected the distal tibial dimensions and radius of curvature (ROC) of a potential donor for anterior glenoid augmentation.

Methods: A retrospective review of magnetic resonance imaging of ankles without bony trauma was performed, and the anteroposterior (AP) and medial-lateral (ML) distances and ROC of the tibial plafond articular surface were measured. Demographic characteristics, including age, sex, height, weight, and body mass index, were recorded.

Results: A total of 141 imaging studies were included (73 men and 68 women; average age, 38.2 ± 12.65 years). All potential specimens accommodated harvest of a 10 × 22-mm distal tibial allograft bone block. Men had greater ML (42.74 cm [95% confidence interval (CI), 42.09-43.39 cm] vs 38.01 cm [95% CI, 37.30-38.72 cm]; P < .001) and AP (38.16 cm [95% CI, 37.47-38.85 cm] vs 34.57 cm [95% CI, 33.97-35.17 cm]; P < .001) dimensions. Significant moderately positive correlations were found for AP dimensions with height (r = 0.584, P < .001) and weight (r = 0.383, P < .001) and for ML dimensions with height (r = 0.711, P < .001) and weight (r = 0.467, P < .001). ROC was positively correlated with height (r = 0.509, P < .001) and weight (r = 0.294, P < .001). Patient age was not related to either the AP or ML distal tibial dimensions or ROC.

Conclusions: After magnetic resonance imaging analysis, all potential donors permitted harvest of a standard-sized distal tibial allograft irrespective of sex or common anthropometric measures, and 85.8% showed distal tibial morphology acceptable for glenoid augmentation. AP and ML graft dimensions and ROC correlated significantly with height and weight.

Level of evidence: Level II, diagnostic study.

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!!

My reverse shoulder replacement

I had my reverse shoulder replacement with Dr.Provencher four months ago. Took an hour, home an hour later. No pain with the meds cocktail, ice machine, and lidocaine pump. My recovery was incredible quick and effortless, no pain and good range of motion. Dr.Provencher is really the best surgeon, and a genuine and kind human being. If you are able to have Dr. Provencher do your shoulder you would be a fool to go anywhere else. The Steadman Clinic is state of the art, extremely efficient, using tranexamic acid intravenously right before surgery to minimize bleeding and many other sophisticated strategies not available in community hospitals. The process and the outcome way exceeded my expectations. If you would like more detail about the experience email me or call on my cell, 3036182303.

My shoulder was ruined in a car accident. I am 82 years old and Dr. Provencher did more than I had ever hoped for. He did a reverse shoulder and at 2 weeks the range of motion exceeded what I had before replacement. He is my hero! Thank you, Dr. Provencher!!
