Abstract:

Background: It is widely accepted that transolecranon fracture-dislocations are not associated with collateral ligament disruption. The aim of the present study was to investigate the significance of the collateral ligaments in transolecranon fractures.

Methods: Twenty cadaveric elbows with a mean age of 46.3 years were used. All soft tissue was dissected to the level of the capsule, leaving the anterior band of the medial collateral ligament (MCL) and lateral collateral ligament (LCL) intact. A standardized, oblique osteotomy starting from the distal margin of the cartilage bare area of the ulna was made. The elbows were loaded with an inferiorly directed force of 5 and 10 N in the intact, MCL cut, LCL cut, and both ligaments cut states. All measurements were recorded on lateral calibrated radiographs.

Results: The mean inferior translation with intact ligaments (n = 20) when the humerus was loaded with 5 and 10 N was 1.52 mm (95% confidence interval [CI], 1.02-2.02) and 2.23 mm (95% CI, 1.61-2.85), respectively. When the LCL was cut first (n = 10), the inferior translation with 5 and 10 N load was 4.11 mm (95% CI, 0.95-7.26) and 4.82 mm (95% CI, 1.91-7.72), respectively. When the MCL was cut first (n = 10), the inferior translation when loaded with 5 and 10 N was 3.94 mm (95% CI, 0.796-7.08) and 5.68 mm (95% CI, 3.03-8.33), respectively. The inferior translation when loaded with 5 and 10 N and both ligaments cut was 15.65 mm (95% CI, 12.59-18.79) and 17.50 mm (95% CI, 14.86-20.13), respectively. There was a statistical difference between the intact and MCL cut first at 10 N and when both ligaments were cut at 5 and 10 N.

Conclusions: The findings suggest that collateral ligament disruption is a prerequisite for a transolecranon fracture-dislocation. An inferior translation of more than 3 mm suggests that at least one of the collateral ligaments is disrupted, and more than 7.5 mm indicates that both collateral ligaments are disrupted.

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!!
