Use of a radiofrequency probe for tenoscopic-guided annular ligament desmotomy.

This research paper explores the use of a radiofrequency (RF) probe for performing annular ligament desmotomy (surgery of tendons) in horses. This technique aims to address common limitations faced with traditional tenoscopic techniques, such as blood loss and cumbersome tools. The outcomes of the study showed successful transection of annular ligament in cadavers and live horses, with no collateral damage and effective management of bleeding. Notably, the use of RF in this surgical procedure also led to satisfactory outcomes for treated horses and their owners.

Methodology and Sample

• The study was conducted using a sample consisting of 14 cadaver specimens and two live horses that were already scheduled for unrelated terminal procedures. These were used to fine-tune the technique of tenoscopic-guided RF annular ligament desmotomy.
• In addition, the researchers examined records of all horses that underwent this procedure between 2003 to 2008, ensuring that there was a post-operative follow-up of more than a year for each horse.

Results and Findings

• The results indicated that the annular ligament was successfully transected in both the cadaver and live horse model limbs using two different commercially available RF probes.
• This transection was seen to be achievable with practice and was verified through gross dissection.
• No collateral damage to surrounding tissues was observed on histopathology, suggesting precision in the technique.
• Out of the 6 clinical cases where follow-up of more than one year was available, 4 horses returned to work, indicating a good recovery rate.
• Owners of all the horses were satisfied with the outcome, suggesting a positive assessment of the procedure’s effectiveness and post-operative results.

Conclusions

• The study concluded that the use of a RF probe in desmotomy allows precise tissue transection under tenoscopic guidance, without causing damage to surrounding structures or inducing bleeding.
• The technique is easy to perform with adequate experience and in clinical patients, a positive outcome can be expected.
• The tenoscopic-guided RF annular ligament desmotomy technique offers several advantages over previously reported techniques. These include effective blood loss management and precise tissue transection, making it a viable surgical alternative for treating horses with annular ligament desmitis and other complex pathology within the tendon sheath.
