Ultrasound Exam: LF Inferior Check Ligament Desmitis

TREATMENT

7/22/21
LF carpal sheath was injected with Hyaluronate and Triamcinalone. After treating the carpal sheath the leg looked better for a week then started swelling again.

8/10/21
Recheck ultrasound showed LF ICL desmitis to be more significant than at first exam, with heat and soreness on palpation. Treatment options were discussed.

8/27/21
Treatment: Ultrasound guided injection LF ICL with Regenaflex.

8/29/21
Bandage was removed, the LF leg was about 50% smaller than before the injection of the ICL. No heat or pain on palpation.Follow up ultrasound on 9/16/21 showed significant improvement.

Left Superficial Digital Flexor Tendon Lesion

Dr. Heather Sherman | John R. Steele & Associates

19 year old pony treated only with Regenaflex-RT.

Client Constraints: able to do only one treatment with no adjunctive treatments.

All therapies were considered: PRP, stem cells, shockwave, laser, etc. With primary considerations being effectiveness and risk of causing more damage, Regenaflex was decided on as the best choice.

Treatment: Early Feb 2022 – 1 dose of Regenaflex; no other treatments.

Post Treatment: Hand-walked for 30 days and then turned out in a small paddock.

See video for full details.

Results: Rechecked at the beginning of August 2022 and was shocked by new scan. The leg had no profile to it, the lesion had filled in really nicely, the fiber pattern was pretty uniform with the rest of the tendon.

“This was kind of a slam dunk case… We were pessimistic about the long-term prognosis given the pony’s age. This case study really sold me on the product because it was such a positive result in a case that probably shouldn’t have had such good results.“

Canine Acute Traumatic Lesion with Dehiscence

Dr. Tony Rodriguez | Foxfield Veterinary Services

Dr Tony Rodriguez of Foxfield Veterinary Services, Downington, PA.

Chumlee: 11-year-old, Male neutered, Shar Pei canine

History & Treatment

Chumlee presented on 1/25/22 after experiencing an acute traumatic lesion to a large sternal mass. The mass was removed, and the site closed under extensive tension. Chumlee returned 1/31/22 for evaluation due to incisional dehiscence. The skin was necrotic and infected thus extensive debridement was required resulting in a large open wound. The resulting wound was approximately 4.5inches (110cm)2. Regenaflex-M was applied on 2/5/22 and a bandage applied.

Post-Treatment Evaluations

2/14/22: Resulted in wound contracture and healing. The site was debrided, scrubbed and silver sulfadiazine applied along with a soft bandage. The wound was approximately 70cm2.

2/21/22: The above procedure was repeated. Approximate wound size was 50cm2.

3/1/22: The above procedure was repeated. Approximate wound size was 30cm2.

3/7/22: The above procedure was repeated. Approximate wound size was 15cm2. At this point the would was small enough to be left unbandaged and the owner was instructed to manage the remaining care at home.

Conclusion

The application of Regenaflex-M appears to have greatly improved the healing time of a large wound and aided in second intention healing. Approximately 20cm of wound contracture/healing was noted weekly.
